To make the suction cups stick better

If you are unwilling or unable to drill into the walls in the bathroom in order to attach hooks for things and towels to them, suction cups will help out. They are also convenient when you need to secure a soap dish so that the soap remains dry and not wet, a cup for toothbrushes, or a miniature shelf for small items. However, everyone knows that suction cups have the unpleasant property of falling off at the most inopportune moment. Few people would like to regularly find soap or their own toothbrush on the floor. Is it possible to make the suction cups stay firmly on the tile? You can, and below we will tell you how.

Suction cups on tiles: methods of reliable fastening

Drills very well with a metal drill without perforation. Can be mounted on drywall dowels. Another question is if it’s a pity to tile, then only install it in spacers with suction cups. Well, if it’s not possible in the walls, then suspended in the ceiling. I have a spacer stand and the shelves are attached to it. The same thing with the curtain.

How to glue a suction cup onto tiles: tips and tricks

Very often, various accessories with suction cups are used for the bathroom, so the question of how to stick them to the tiles is extremely relevant. These items are convenient, but installing them can be a challenge. There are several reliable methods that will allow you to fix the product on the tile surface without a single trace.

As a rule, suction cups do not stick well to tiles, so to securely attach them you have to resort to various tricks

The nuances of installing mirror elements in bathrooms

To ensure a high service life of the mirror and user safety during installation, some nuances should be taken into account:

type of enclosing/dividing structure - concrete wall, plaster or plasterboard on a profile frame;
weight, dimensions of the mirror element;
reflection angle - the mirror can be placed in the same plane with the wall, its upper edge can be tilted outward, and hinged fasteners can be used to provide several degrees of mobility.

Concrete walls and plaster under a layer of tile adhesive have high strength and, accordingly, load-bearing capacity. Plastic dowels for self-tapping screws and anchor hooks are held securely in them. Standard installation technology is used here - drilling, driving in dowels, screwing in hardware.

On drywall covered with tiles, which has normal load-bearing capacity but is extremely thin, a special plastic or metal anchor will help you hang a mirror element, as in the bottom photo.

Heavy reflective sheets are best fixed with holders, through holes drilled through with self-tapping screws, or glued to a neutral sealant. For lightweight, small-sized mirrors, you can use the other mounting methods indicated in this manual.

Suction cup accessories and their advantages

Most often, suction cups are used in the bathroom. But there are many similar accessories for other rooms. Such products have a number of advantages:

They can be fixed to the surface in just a few seconds, without the use of auxiliary tools.
They do not leave a mark on the tile surface.
If necessary, the suction cup can be removed or moved to another location.
The cost of these accessories is low.

Thanks to these properties, as well as many other positive factors, suction cup accessories are incredibly popular. Today the following products are produced with this mount:

soap dishes;
hooks;
shelves;
cup holders;
shower holders;
decorative items;
holders for toilet paper, towels, cosmetics, etc.

Products with suction cups have proven themselves to be durable, cheap and convenient accessories for bathrooms

We'll look at how to attach a soap dish and other products with suction cups to tiles below.

What are silicone wall holders (video)

Silicone Velcro are modern holders that ensure reliable and secure fastening. If done correctly, suction cups can last for many years.

It is important that the material from which they are made is of high quality. You should check that there are no roughness or bumps on the surface of the Velcro

You should also pay attention to the surface of the tile itself - it should be smooth. Any defects will lead to the fact that the suction cup will not hold and will often fall off

The suction cups hold well if they are attached to the sealant.

Tile is one of the most common materials for finishing a room. Especially often, tiles are used to decorate the walls and floors in the bathroom or kitchen. In these rooms, it is convenient to use silicone wall holders to attach various objects to the wall. Several reliable methods will help you secure the suction cup so that it holds tightly to the wall and does not leave an unsightly mark after dismantling. Silicone holders can be used in different rooms, but most often they are attached to the tiles in the bathroom.

Suction cups are incredibly popular among consumers. This is understandable because they are easy to mount on the wall and do not require drilling any holes in the tiles. Many products are already produced with Velcro.

When purchasing, you should pay attention to the surface of the suction cup - its inner surface should be absolutely smooth. This factor is very important, as it decides whether the suction cup will be suitable for mounting

You should also choose only suction cups of the correct shape.

Advantages of suction cups:

They are quickly attached to the surface, without the need to use auxiliary tools.
They do not spoil the tiles with unsightly marks on its surface.
They are distinguished by their mobility. They are easy to dismantle and move from place to place.
The low cost allows you to purchase various types of suction cups.

With suction cups already attached, you can buy a soap dish, special hooks, shelves, shower holders, various accessories, toilet paper holders, etc. Silicone suction cups are durable, economical and have a large selection

When purchasing a suction cup, it is important to remember that not only the quality of the accessory is important, but also the type of finishing material

Surface quality and suction cup

First of all, you need to make sure that the product you buy with a suction cup will not be unsuitable for fastening. High-quality material must have an absolutely smooth inner surface. It is this factor that determines the choice. Be sure to run your fingers over it. If you feel a depression or bump, it is better to refuse such a product.

Please also note that the shape of the suction cup must be correct.

Another important aspect is the assessment of the tile surface. It must be perfectly flat, since it will not be possible to glue the suction cup onto a textured tile.

Glue "Moment"

If the tape and suction cups cannot withstand the necessary loads, use Moment glue. Apply a layer of glue to the wall and wait 10 minutes for the hook, then press it firmly to the wall. After 24 hours the grip will be at its maximum.

If you use glue in the bathroom, pay attention to whether the fastening will be strong in rooms with high humidity

In addition to the proposed methods, various types of glue can also be quite effective - epoxy, super glue, liquid nails. The main thing is to understand what the humidity is in the room, the load on the hook, and how to dismantle it if necessary. You can fasten metal hooks into the gaps between the tiles - a blank in the shape of the letter T is made from stainless steel 1 mm thick, the length of the “top crossbar” is 15-20, the “legs” are approximately 25-30 mm, the width is 5. The seam is cleared with a piece of a hacksaw, the crossbar is inserted into a horizontal seam, covered with joint compound, after drying, the end is bent upward with a hook. If necessary, you can pick out and rub the seam again. The advantage is that no marks remain. Withstands more than 5 kg. What methods do you use to hang heavy and not so heavy objects?

Why don’t the suction cups stick to the tiles (shelves, hooks, soap dish), what to do, how to secure them?

Smooth gloss is best suited for this purpose. Pores on the matte surface can weaken the bond. And raised protrusions, various surface defects, particles of glue or putty are not at all capable of holding the suction cup.

In order for the suction cup to adhere well to the tile, you need to make sure that the product is of high quality, and that the tile is even, and preferably glossy

It will not be possible to securely attach the suction cup to a chip or crack. Unfortunately, it will not be possible to disguise these flaws in this way. The only way out is to fix the object hanging down a few centimeters above this flaw.

How to attach: instructions

A couple of tricks will help you cope with the task. These are not exactly standard methods of attaching suction cups, but they give long-lasting results.

How to glue Velcro securely, all stages:

First, degrease and wash the surface. Remaining dirt significantly reduces the stickiness of the suction cup. To degrease the tile surface, use a regular soap solution. Another way is to wipe with alcohol.
Degrease the Velcro surface as well.
If the suction cups come with mugs with a sticky side, do not neglect them: they will make the attachment stronger.
Place the suction cup on the cleaned wall and apply maximum pressure.

You can attach suction cups to bare tiles, but the result will be short-lived. It is better to make additional mugs yourself or look for them complete with suction cups. To make it yourself, you will need self-adhesive polyethylene film, which is used for office purposes - for laminating paper without heating. Just cut out circles of the appropriate size, stick them on the tiles, and only then attach the hooks.

An easy way to improve the quality of adhesion is to apply an additional layer of Vaseline or a cream of similar consistency to the inside of the suction cup. This substance is safe for various surfaces. The method is used for further placement of light objects on suction cups.

Mounting methods

Let's move on directly to the issue of installation. There are several ways to stick objects with suction cups to tiles. Of course, they will hold up well and perform their functions only if the above conditions are met. The most popular fastening approaches are:

using alcohol for degreasing;
the use of petroleum jelly or other similar products;
PVC film backing on a self-adhesive basis;
strengthening the suction cup with silicone sealant.

Methods for strengthening the attachment of suction cups to the surface

The first method is suitable for objects that are small in size and weight. For example, this can be used to secure a plastic soap dish. The essence of the method is to completely clean and degrease the surface of the tile. In other words, you need to thoroughly clean it of any contaminants: dust, dirt, limescale, rust, grease, soap, etc. Then treat the suction cup itself. Alcohol is best for degreasing. After such manipulations, just press the suction cup tightly against the tile, and it will remain in the place you want. If you need to move the product, wet the tile next to the suction cup. It will glide easily on such a surface, but you won’t have to peel it off.

What should I do to prevent it from falling off?

There are only two tasks:

Clear the atmosphere inside as much as possible.
Don't let that negative pressure escape

This is why the side edges of the suction cup are made so wide! And they try to make the material as elastic as possible so that it adheres well to the glass.

Often normal fastenings fall off due to the fact that the suction cup is not sealed. And to make it as good as possible, you just need to wet the surface. Any liquid seems to clog the “microcracks” and prevent air pressure from leaking out. And yes, water is not exactly the best option.

Many people wet the surface with water (or even saliva), this is of course correct, but in winter it can freeze, but in summer it simply evaporates. Therefore, you need a composition that will not evaporate, freeze or harden. Motor oil is ideal, you need a little on your finger, wipe the surface of the suction cup and attach it to the windshield. WILL HOLD ON for a very long time!

The second “jamb” of modern gadgets is the “lever” in the mount, which creates a lot of pressure. Often it makes almost a full turn (180 degrees), but it starts working only at the very pressure, only 25 - 35 degrees, that is, the remaining angle works idle. We need to reduce this idle speed, which is done - a circle is cut out of a regular car camera, along the rim of the suction cup (like a gasket), then all the insides are cut out inside and it is inserted between the suction cup and the body.

Once you start pressing the suction cup with the lever, this “spacer” will reduce the idle speed and increase the pressure inside. IT WILL HOLD SEVERAL TIMES BETTER, tested many times.

Here's a short summary:

Checking the rubber or silicone surface for damage
Degreasing glass
Lubricate the surface of the suction cup (motor oils are ideal because they do not freeze in winter and do not evaporate in summer)
You can make a spacer (ideally from a wheel tire) between the plastic and rubber (silicone) components, thus increasing the pressure

Now we are watching a short video version.

DVR mount

The suction cup type bracket allows you to place the DVR in a place convenient for the driver. The device should not obscure the view, but at the same time be positioned so that the person sitting behind the wheel can turn the video recording device on and off at any time and see what is displayed on the screen. The holders have different designs, as well as different areas of the fastening element itself for installation; fasteners can be purchased separately from the recording device itself.

Suction cups can be rubber and silicone, with a lever or the simplest, with a side rotating mechanism, with two rubber/silicone fasteners, there are other types. The brackets included in the kit are designed taking into account the weight of the recorder, but do not always fulfill their purpose.

Soda and garlic

Sugar syrup or regular soda can also be used to create an adhesive surface. The main thing is to look at the label before use and evaluate the amount of sugar it contains. If there are more than 400 calories, then the sugar will exhibit the properties of glue when it dries. Next, you can wipe the area of the windshield where the console should hang with the drink, and also apply a few drops to the rubber. After drying, the rod can be attached to the chosen location.

If you don’t have sugar syrup or lemonade on hand, you can use any sugar-containing product. It could be pieces of fruit or even garlic. When dried, its juice has an adhesive property. It can also act as a sealant.

Why doesn't the suction cup hold?

Often the manufacturer is blamed for the weak fixation of the DVR on the glass; indeed, it is difficult to expect super characteristics and high quality workmanship from a cheap gadget. But is it worth shifting the blame to the manufacturer? There are quite a lot of reasons why the fastener falls off:

the suction cup was not installed according to the instructions;
the glass is dirty (oily), dust and greasy stains make it difficult to ensure tight contact;
due to heating (for example, being in direct sunlight), the mounting area has become deformed, and a vacuum is not created;
the holder was attached in cold weather;
the surface for attaching the suction element is uneven;
The bracket is not original and is not designed to support the weight of this device.

To understand the issue, you first need to understand how vacuum fasteners work and their principle of holding them on a plane.

How to securely glue the suction cup?

How to reliably glue the suction cup “tightly”, but without using any “superglue”? The advantages of suction cups are that you don’t have to damage the walls, you don’t need to nail them down or drill holes for them. Suction cup fastenings provide convenient installation, ease of adjustment and easy disassembly. The reliability of the retaining element is affected by such points as:

the quality of the raw materials from which the suction cup itself is made;
presence of defects on the suction element;
total weight pressing on the suction cup;
the structure of the material on which the Velcro item should be located.

It often happens that on the concave side of the suction cup there are various defects in the form of tubercles, seams, microcracks and other flaws formed during manufacturing or transportation. Such moments do not allow the Velcro to stick evenly to the surface, so after a while it falls off. If a seam or other protrusion is detected, the layering should be immediately carefully removed with a blade or utility knife. Cracks and breaks are difficult to repair, so it is better to immediately replace the suction cup. The structure of the suction cup must also be correct and even.

Another circumstance that prevents the suction cup from sticking tightly is a rough or embossed surface. If the tiles are made with patterns or non-uniform texture, then the fastening element will not be held. Also, glue particles, various seam putties and the joints themselves are not able to hold the suction cup.

How is the DVR bracket held in place?

A “suction cup” type fastening element is held on the plane due to a pressure difference; when a silicone or rubber circle is flattened on the surface, a reduced pressure is formed inside it. But the bracket is fixed only when the material is absolutely sealed and no outside air gets inside the circle. If there is even a microscopic hole in the rubber band, there will be no suction effect, such a holder can be safely thrown away. The suction cup can only be secured if it is completely sealed, and you cannot press it and immediately release it, in which case it is guaranteed to fall off.

Attach to glass

To attach suction cups to smooth glass, no additional equipment is needed; the main task is to properly wash, treat and degrease it. Many drivers complain that the suction cups of navigators, phone stands, and radar detectors do not stick to the windshield; most likely, installation occurs on a dusty, uncleaned surface.

In preparation for installing accessories on the suction cup, it is important to clean the windshield from all dirt at the mounting points, as well as degrease the surface. An excellent solution would be a glass cleaning liquid that must contain alcohol. It is necessary to treat both the glass and the suction cup itself with this product, after which the reliability of the fastening will not raise any doubts.

Modern suction cups do not have extremely strong fastening strength characteristics, however, they can always be strengthened using the simple methods described above. By using them, you will not think about when your object on suction cups will fall. Use beautiful and comfortable decorative accessories on suction cups for your pleasure.

Under what conditions is it difficult to install the holder?

The most common reason for weak fastening of the DVR bracket is low temperature, usually the suction cup falls off in the cold. This happens because rubber or silicone hardens at low temperatures and loses its elasticity. Also, the rubber band does not hold up in the heat; if you left the car for a while in the sun, you should not be surprised that upon your return you will find a fallen recorder.

It will be difficult to install the holder on glass covered with dust; the rubber circle itself should not be dirty either. The suction cup holds very poorly on uneven glass, for example, if it is silk-screened. Here it is no longer possible to level the surface; you need to figure out how to ensure tight contact. Another thing to consider is that there are a lot of Chinese products on the Russian market, and the fastener may initially be defective.

But if you can’t immediately secure the bracket well in the car, there is no need to despair; there are many different tricks and folk methods that you can use to securely install a portable device on the windshield.

What should I do to solve the problem?

Based on the reasons given above, let's consider what can be done to prevent the DVR from falling off:

If you find a defect on the new suction cup (external defect, cracks, tears, uneven surface, etc.), return the device under warranty. Such a bracket will not hold the DVR properly. Or buy a new one.

Of course, installation of the mount is carried out strictly according to the instructions given in the service book. Below we will also give a universal algorithm;
The glass or mounting surface must be perfectly clean and dry. It is advisable to wipe the windshield with an alcohol wipe;
Strong heat can soften rubber or silicone, and cold, on the contrary, can make it “oaky.” As a result, the elasticity of the material is impaired, so the suction cup of the DVR does not stick to the windshield. Carry out installation at normal temperature (room) of glass and air inside the cabin. In winter, it is better to drive the car into a warm parking lot.

If the rubber does not hold the main structure due to the uneven surface of the windshield (for example, it is silk-screened, cracked, chipped, etc.), alas, you will have to look for another place for installation. It will not be possible to create an ideal vacuum on such a surface.
When choosing a third-party bracket, make sure that it fits your DVR exactly (weight, area of the suction element, etc. properties).

Rules for attaching the recorder holder

Before using cunning methods and non-standard techniques, you first need to try to install the suction cup according to all the rules. We install the DVR by performing the following steps:

With a clean napkin or rag moistened with alcohol or degreaser, we wipe the surface on which the device will be mounted, and we also degrease (clean) the base of the recorder bracket;
we wait for some time, we need the treated surfaces to dry;
press the holder tightly against the glass, if it has a lever, press and lower it, hold it for a minute or two, it is necessary for the suction cup to “grab” and secure in place;
After installing the bracket, we check the reliability of the installation - we try to unfasten the holder by hand, but there is no need to pull very hard.

Degreasing and silicone

Even new and high-quality fasteners do not adhere well to dirty glass. Therefore, before use, it must be washed from the inside and degreased. This is done using special chemicals. After wiping the glass with a soft towel, it doesn’t hurt to apply a layer of alcohol and wait for it to dry, for which you can use disposable wipes or ethyl alcohol.

The vacuum rubber membrane can also be degreased and then rubbed with silicone grease. It is necessary to treat its external surfaces to prevent moisture and air from entering through the pores of the rubber. You can use clear plumber's silicone. But you cannot apply too much of the product, otherwise a film will form between the glass and the rubber, from which the mount will slide off.

Methods to help securely attach the bracket

There are methods that help to secure the suction cup more securely, here are some of them (as car enthusiasts advise):

warm up the fastening element by bringing it close to the heater fan, while the car interior must be warmed up;
use double-sided tape;
coat the contact surface of the bracket with silicone;
cut a rubber gasket along the diameter of the circle and place it between the glass and the holder;
To seal, add a little glycerin to the contact surface; you can also use laundry soap and garlic juice.

Not all of the listed methods work 100%, and there are side effects. The adhesive tape holds up well, but in the sun it heats up and loses its properties. An additional rubber gasket helps in many cases, but you just need to take into account that the DVR becomes a little heavier, the load on the bracket increases (it can break), and adding rubber is pointless on suction cups without a lever. Garlic juice always helps, but not everyone likes the smell it gives off. A solution of laundry soap gives a good effect, you just need to take one thing into account - until the soap has dried, you can move the suction cup on the glass, then everything will set tightly. Silicone should be spread in a not too thin layer, evenly, its disadvantage is that it sets well only after a day; if you drive the car right away, the fasteners may fall off. Another drawback is that the silicone-lubricated holder moves across the surface.

The suction cup comes off the windshield, what should I do?

Have you ever gotten into your car in the morning and found car glass holders lying on the floor, seat or dashboard? Have there ever been situations when the suction cup for the DVR fell off right on the road, on the next bump? If yes, then we will tell you how to avoid such surprises.

Why doesn't the suction cup hold?

The most common reason is cold. In winter, the windshield freezes, the rubber suction cup loses its elasticity and falls off. In such cases, drivers usually warm up the car, place the suction cup under the airflow and attach it back. This method, despite its prevalence, rarely leads to long-term results.

But sometimes the suction cup doesn't hold up well in the heat. If in the summer the car is often left in direct sunlight, this leads to numerous sad consequences, one of which is deformation of the holder mounts.

And sometimes the suction cup holder cannot be installed from the very beginning; it simply does not stick to the glass. There are two main reasons: either the glass is dirty or there is a layer of dust on the suction cup, or you got a defective holder.

What should I do to make the suction cups stick?

Act according to the situation.

There are several working methods, tested by many drivers, to restore the elasticity of a frozen suction cup.

Warm up the car. Wipe the windshield with alcohol and wipe dry. Warm the suction cup, clean it of dirt and apply it to the glass. To be on the safe side (and if you have the means at hand), before putting the holder back in place, treat the suction cup with clear plumber's sealant or silicone grease.
Budget popular option. Boil the mount in a soda solution for about 20 minutes. To make a solution of suitable consistency, take a teaspoon of baking soda per glass of water.
A completely budget and desperate option for the most extreme case. The suction cup can be attached to glass or a dashboard using double-sided tape. This option is suitable only if you have nothing on hand except tape, and you need to secure the holder.

Most often, the suction cup can be easily returned to its place by simply warming it up and degreasing the area on the glass. But if the mount is deformed or continues to fall off despite all your efforts, don’t worry and just buy a new suction cup holder. An excellent choice would be the Partner car holder for tablets.

Modern gadgets have become a part of our lives and our cars. Most modern gadgets (DVR, radar detector, phone holder, etc.) “stick” to the windshield.

But sometimes this whole structure falls, and sometimes it breaks the gadget into junk. And all this is because of the suckers (usually 2-3). There are also gadgets with one massive suction cup, which has an additional lever to enhance the effect. But sometimes it is not able to support the entire structure due to poor quality materials or improper installation.

Questionable ways to attach the holder

There is a lot of advice that motorists give, but how useful they all are is a big question. Drivers also advise:

lubricate the contact surface with engine oil;
use brake fluid as a fixing agent;
moisten the contact with saliva;
attach the bracket with superglue;
attach the suction cup to the sealant;
To improve contact, use Pepsi-Cola.

Motor oil is a good way to create reliable contact, but we must not forget that the quality of the rubber seal of the suction cup, especially from Chinese manufacturers, varies; the rubber can swell and “float”. Brake fluid and saliva are water-based, and when the moisture dries, the contact reliability deteriorates. Automotive colored sealant does not look aesthetically pleasing; it is possible that traces will remain after its application, but transparent silicone sealant will come in handy. Some people attach the suction cup with superglue, but this seems like a perversion - it is not a fact that the mount will not fall off, but scraping off the remaining glue from the glass will not be easy.

Tips for different types of surfaces

Different types of surfaces, for example, tiles, plastic, glass, have some nuances in the process of gluing the suction cup.

Tile

Most often, it is on the tiles in the bathroom that you have to glue a variety of hooks, shelves and holders. In order for the adhesion of the suction cups to the tile surface to be as effective as possible, you should adhere to the following recommendations:

Ventilate the bathroom if it is damp.
Prepare the surface of the tile by washing it thoroughly, for example, using dishwashing detergent or ordinary soapy water. If necessary, additionally use alcohol-based degreasing agents.
Wipe the tiles dry.
Place the suction cup on the tile and press it firmly.

Important! Do not overload shelves and hooks. Try not to pour water on the area of the suction cups, as the weight of the water may cause the suction cups to move or fall off. If you need to glue the suction cups inside the shower stall, use transparent silicone sealant, this fastening will be more reliable.

Plastic

To properly glue the suction cup to the plastic, you need to pay attention to the surface. If it is smooth and even, then there will be no problems with fastening. © https://ydoo.info/qa/kak-prikleit-prisosku.html The algorithm of actions is simple:

Surface cleaning.
Degreasing.
Suction cup gluing.

If the suction cup needs to be attached to a car dashboard and similar surfaces where there is a “pattern” on the plastic, it is best to use a special suction cup with a lever, which during the fastening process creates a vacuum under the suction cup. Conventional suction cups do not adhere well to textured surfaces; they must be additionally secured with self-adhesive PVC films.

Glass

How to properly attach a suction cup to glass? It is this surface that causes the most problems. Thermometers attached to the window, as well as holders for video recorders on the windshield, very often fall off due to exposure to high temperatures in summer and low temperatures in winter. Attaching suction cups in an aquarium causes no less problems. It is quite possible to securely fix the suction cup if you follow the recommendations below.

How to glue a thermometer?

To firmly glue a thermometer with suction cups to window glass, you must follow the general principles of fastening: checking the suction cup for defects, cleaning and degreasing the glass. In addition, the following recommendations must be taken into account:

Place the thermometer in warm weather with minimal humidity.
To secure, select a north window, or at least an east or west window. At the same time, place the thermometer itself in the shade. Avoid direct sunlight.
Place the thermometer away from sources of heat or cold (meaning ventilation systems).

If necessary, increase the adhesive properties, lubricate the surface of the suction cup with Vaseline or silicone sealant.

Attaching the holder to the windshield

In order for the suction cup to reliably stick to the windshield, you need to make sure that the suction cup itself has no damage or other defects, and that the place on the glass where the suction cup will be glued is clean and free of grease. In addition, you should pay attention to the material of the suction cup. It is better to give preference to rubber, since in the cold in winter it does not tan as much as silicone. More reliable suction cup options are those equipped with levers. You can strengthen the adhesion to the surface of the windshield using a self-adhesive film, which, as a rule, comes complete with the holder. It is also worth paying attention to the options for holders impregnated with a special adhesive composition.

You can strengthen the attachment of the suction cup to the windshield using Vaseline or silicone sealant. But it is not recommended to lubricate the suction cup with machine oil or any other oil. It has a negative effect on rubber and silicone.

A popular way of additional fixation is to lubricate the surface of the suction cup with garlic juice. When dry, it will act as glue.

If the suction cup is equipped with a lever, then reducing the idle speed of the lever will help to fix it more securely, which will create more pressure under the suction cup. To do this, you need to cut a circle from a piece of rubber (a car inner tube will do) to the diameter of the suction cup, and then cut another circle of a smaller diameter in it. There should be a gasket. It is placed between the suction cup itself and the body, which is placed on top of it.

How to attach a suction cup to an aquarium?

Attaching a suction cup in an aquarium is no more difficult than on any other glass. The problem arises during operation. Due to constant exposure to water, rubber suction cups become tanned and lose their properties. Literally 2-3 months and the suction cups on the filter fail. But they can be revived quite easily. The stiffened suction cup needs to be kept in boiling water for about 10 minutes, after which it will soften and can be securely attached to the aquarium glass again.

To improve adhesion, you can use medical Vaseline. It is not harmful to aquarium fish.

Recorder bracket repair

There are often cases when the suction cup itself becomes unusable: the plastic pin holding the “hat” breaks. This happens if you remove the DVR and pull it by the body without being careful.

One way to fix it is to smear the pin with superglue, but the connection will not hold for long, sooner or later the “cap” will fall off. The easiest option is to buy a new mount, but you can still try to restore the suction cup; repairs will cost much less than the purchase. Let's look at how you can repair a suction cup with a lever:

disassemble the bracket - use a Phillips screwdriver to unscrew the screw and remove the cap;
remove the pin;
dismantle the spring and the rod with the broken base;
Using a 3.5 mm drill, we drill a small hole in the body of the rod (in the place where the lower part of the suction cup was attached);
we clean the area, take two wide washers, coat them with glue and place them on the sides of the rubber diaphragm;
take a screw or self-tapping screw 10-12 mm long with a countersunk head, also apply glue to it, screw the fastener into the drilled hole;
remove any remaining glue from the outside and let the structure dry;
we assemble the bracket - put the spring in place, connect both parts of the device, fix the pin;
if the suction cup has a large free movement, it will not press well against the glass, in this case we cut out an additional elastic band for it;
We put the cap on top, assemble the holder completely, the work is finished, the mount can be used again.

Thus, you can restore almost any bracket for a DVR; the procedure takes little time, and there is no need to buy a new holder.

I FOUND THE ANSWER MYSELF, IF SOMEONE WILL SEARCH.

» Everyone knows the various accessories for the bathroom (shelves, hooks, etc.), which are attached to the tiles with suction cups. Convenient and practical! But.. . Over time, the plastic from which the suction cups are made loses its elasticity and shape, and ceases to adhere to the wall. There are many different methods - moisten with water, soap. But all of them are not effective. The suction cup still falls off after a day or two
