What paint you can glue the wallpaper and how to do it correctly

For many home improvement projects, gluing wallpaper over paint is a practical and frequently necessary solution. It can significantly impact the outcome to know how to apply wallpaper to painted surfaces correctly, whether you’re updating the appearance of a room or hiding flaws.

Choosing the right paint for your walls is an important part of the wallpapering process. Not all paints are meant to be used on wallpaper, and choosing the incorrect type can result in peeling and poor durability. Wallpaper glue usually adheres well to walls painted with latex or acrylic paint. Glossy and oil-based paints, on the other hand, can be trickier and need more setup.

It’s critical to properly prepare the painted surface before beginning. In order to prevent the wallpaper adhesive from becoming tangled, the walls must be cleaned of any dust, oil, or other debris. In certain situations, you might need to lightly sand the walls to give them a rougher surface so the glue will stick to them better. It’s also essential to make sure the surface dries completely to stop the wallpaper from bubbling or lifting over time.

The strength of the bond between the paint and wallpaper can be increased by priming or applying adhesive sizing to the painted wall. These products are especially helpful if the paint is glossy because they improve the adhesion of the wallpaper adhesive and can produce a more even surface. After the primer dries, you can hang the wallpaper by gently smoothing it to remove air bubbles and make sure it adheres tightly to the wall.

You can achieve a stunning and durable wallpaper finish over painted walls by selecting the appropriate paint and carrying out the necessary preparation steps. This method not only makes your space look better, but it also makes sure that the wallpaper stays put, giving you a long-lasting and eye-catching finish.

Type of Paint How to Glue Wallpaper Correctly
Latex Paint Ensure the paint is fully cured. Clean the surface and apply a wallpaper primer before gluing.
Matte Paint Lightly sand the surface to create a better grip, clean thoroughly, and use a primer before applying wallpaper.

Advantages and disadvantages of such technology

  • the lack of the need to clean the finish, level the walls and wait for the preliminary layers to dry (all this reduces the repair time several times);
  • Blinking with minimal preparation is less laborious than a complete replacement of the cladding, therefore it can be carried out independently in 1-2 days;
  • money that would be necessary for the purchase of washing products can save or buy better wallpaper and glue for them;
  • With minimal preparation, only the surfaces around the processing zone are dusting, the risk of prolonged dusting of the apartment is absent.

The following are some of the installation’s shortcomings when done on painted walls:

  • wallpaper glue is not adapted for grasping with a painted wall, so the canvas can quickly fall off due to insufficient adhesion of surfaces;
  • A layer of paint can actively absorb water or, on the contrary, repel it, which leads to deformation and lag of wallpapers or a deceleration of glue drying;
  • If the lower coating has low vapor permeability (for example, oil paint), then moisture will accumulate under the canvas, which provokes the development of mold;
  • If the wallpaper and the preparation method are improperly, the wallpaper will be bubbled, locally depart from the walls and fall off with a minimum physical effect.

If the paint was adhered to wallpaper that rapidly moved away from the wall, the room’s owner will need to spend more money on finishing and perform twice as much prep work.

Following an unsuccessful attempt at repair, the canvas remnants must be removed, the surface must be cleared of any glue residue, the paint must be removed or washed off, and plaster and primer must be applied.

Choosing the appropriate paint type is essential when adhering wallpaper to painted walls in order to guarantee a smooth finish and proper wallpaper adhesion. Generally speaking, glossy or semi-gloss finishes are too slick for wallpaper adhesion; matte or flat latex paints offer a better surface. The painted surface should be well cleaned and lightly sanded before beginning to remove any sheen and impart a slightly rough texture. To further enhance adhesion, apply a high-quality wallpaper primer or sizing to the wall. You can successfully apply wallpaper over painted walls and achieve a polished, long-lasting finish by following these steps.

Which covers is impossible to glue the wallpaper

The following surfaces should not have wallpaper adhered to them:

  1. Walls affected by the fungus. To prevent the appearance of mold and the lag of new wallpaper, it is not enough to clear visible traces and use glue with antimicrobial properties. To remove mold, it is necessary to remove the paint, clean the wall and treat it with fungicide, vinegar or hydrogen peroxide (70%). After drying, the cause of the development of the fungus should be eliminated – for example, close the surface with a layer of mesh heat insulator and plaster. Under wallpaper the surface is primed with a composition with antifungal properties.
  2. Whitewash. Lime paint does not ensure wallpaper sticking. The weight of the wallpaper strips falls on a small surface layer of whitewashing, which is easily lags behind. To ensure adhesion of glue, you need to wash off most of the lime and primed the wall after drying.
  3. Cracking water -based and oil paint. If there are fragments of a rampant finish under a layer of wallpaper, then bubbles occur in the middle of the canvas, and at the joints – areas of discharge. Coating with large defects or nets of cracks must be replaced completely.
  4. Old paint on the walls of the kitchen. Vapor -permeable LKMs get smells well. Particles of fat that are formed in the process of cooking, penetrate deep into the coating layer and reduce the strength of adhesion to the adhesive composition. Fast -fixed wallpapers will retreat with friction with a sponge and washing. To extend their service life, the painted walls of the kitchen must be thoroughly washed from dirt and fat, and partially polished the paint.
  5. Multilayer coatings. With a lack of finance and time, the walls are painted on top of the old paint without preparing the surface and accounting for compatibility of coatings. If the adhesion between the layers is low, then the load from the weight of the glue and the canvas will accelerate the formation of defects. The thickness of the layer, in turn, does not allow you to level the damaged area without removal.

Preparation of walls depending on paint

Depending on the type of paint, there are differences in the method for priming the wall before adhering wallpaper. The way that the coatings break, react to moisture, and leave behind different characteristics when touched.

You must carefully examine the walls, assess their condition, conduct multiple tests for the type of paint, and choose the best processing technique in order to prevent the wallpaper from oscillating.

Acrylic base

An advanced subspecies of water-based paint is acrylic paint.

The following indicators point to the polymer basis:

  • bright color (acrylic holds pigments for a long time and does not burn out even with prolonged exposure to UV rays);
  • lack of reaction to high humidity (the finished polymer layer withstands up to 5-10 thousand. washing cycles);
  • the possibility of intensive cleaning (acrylic coating is wear -resistant and withstands up to 2000 abrasion cycles);
  • lack of a specific smell of olifa.

A matte or satin finish is produced by acrylic paint. The addition of varnish and resin, which lessen glue adhesion, gives a glossy shine.

It will take work to remove polymer-water-emulsion paint because of its deep penetration into the wall. The coating breaks into tiny pieces as it cracks.

  • Acrylic waterproof paint;
  • Acrylic paint for wood;
  • Acrylic paint for the bathroom;
  • Acrylic paint for furniture;
  • Acrylic paint in spray cans;

An acrylic surface needs to be prepared with:

  • moisten the walls with soapy water, clean the stuck pollution and wash thoroughly;
  • wait for complete drying;
  • Mix the solvent and a primer of deep penetration in a ratio of 1: 1, apply to the surface in 2 layers with an interval of 6-10 hours;
  • mix PVA and pre -divorced adhesive composition for wallpaper (2: 1);
  • Process the walls with the resulting glue, wait for drying;
  • Start glow.

In order to provide the primer with a deeper penetration and the required roughness, the solvent partially corrodes the polymer.

The preparation process is the same as for an oil paint layer if the surface is coated in acrylic varnish or alkyd paint.

Laundice whitewash

One of the least expensive decorating techniques is lime whitewashing.

Among its unique qualities are:

  • low moisture resistance (the coating is easily washed off with water);
  • the formation of chalk powder with a spatula with a spatula;
  • traces on the hands, fabric and other soft surfaces in contact.

Lime compounds can have colors other than white; they can also have bright, fairly persistent colors thanks to alkaline-resistant pigments.

The white surface needs to be thoroughly cleaned or covered with a composition that offers the best adhesion because it cannot support even a light sheet of paper.

There are two ways to get the walls ready:

  1. Moisten them with a warm soap solution and carefully clean the soft layer of lime. After removing the whitewash, you need to thoroughly wash the surface, removing the remaining whitewashing. For verification, you need to draw a hand over all the walls after drying them out. If white traces remain in the palm of your hand, the procedure should be repeated.
  2. Process the surface with a deep primer, wait for complete drying and repeat. After drying the second layer, apply thick wallpaper glue on the wall (not more than 20-30% of water). The dried surface will be ready for gluing.

Oil base

Several distinguishing characteristics of oil-based paint include:

  • The barely tangible smell of olifa even on the old coating;
  • removal of the layer in large pieces after damage by a spatula;
  • glossy shine.

This surface works well with other cladding types, is moisture-resistant, and is simple to clean. Due to the lipophilic coating’s resistance to water, the glue and primer do not adhere well to the oil base.

The subsequent techniques are appropriate for wall preparation:

  1. Grinding with a coarse -grained sandpaper or abrasive circle. Mechanical processing allows you to create roughness on oil coating without wall cleaning. Microsics provide better adhesion to the surface. After processing, you need to apply 1-2 layers of primer, and a mixture of wallpaper glue and PVA (1: 1) on a dried wall. The disadvantage of the full grinding is a large amount of dust and the complexity.
  2. Lanes formation. With a small amount of work, you can limit the zones of adhesion. To do this, you need to remove the paint with vertical stripes with a width of 5-6 cm with an interval of 20 cm. The coating is removed using a chisel and a construction hairdryer (the heated base becomes softer and supple). Clean zones are primed in 1-2 layers, put off on a crush with paint and covered with adhesive composition.
  3. Creating a grid. If you need to process a large surface, and there is no time for full grinding, then you can make notches in the form of a grid with a gap of 5-7 cm. To create defects, you can use a pick, a spatula and a hammer. The treated walls are cleaned of dust, treated with a primer and left for a day for drying. A gypsum plaster is applied on top of the primer layer. The final stages of preparation – grinding walls with fine -grained sandpaper and repeated priming.

Water -based coating

The level of moisture resistance determines the classification of paints that are based on water. Detergents are compositions made of silicone, acrylic, and latex. The technology mentioned above is used to get their layers ready for wallpaper.

More affordable colors—like those made of polyvinyl acetate—are susceptible to moisture. You can use warm water or a mild liquid soap solution to clean the wall and test the composition’s resistance. Without a solvent, water-based paint that is unstable will start to wash off.

Making sure the surface is water resistant is the primary responsibility when preparing it. Applying glue to an unprepared wall will cause the paint to start exfoliating, which will cause the wallpaper to peel.

Prior to applying the glue to the canvas:

  • thoroughly wash the walls with a sponge moistened in soap solution;
  • rinse, wait for drying;
  • Process the surface with an insulating primer, wait for 6-10 hours, apply the second layer of the product;
  • Leave for drying for at least a day (to accelerate the process, you can turn on heating devices or open a window if the weather is dry on the street).

You can use the same composition that you used for the acrylic surface when gluing.

Choosing wallpapers for paint

It is advised to use non-woven wallpaper for wall decoration over paint. Only an acrylic or plastered oil base can be used to glue the vinyl canvas because it is too heavy.

The paint hold of liquid wallpaper is just as good as that of non-woven. The coating’s polyvinyl chloride provides adhesion strength. Although they don’t put much strain on the adhesion layer, paper wallpapers don’t last very long. Their sole benefit is their affordability.

The glass wallpaper needs to be aligned and prepared beforehand because it is glued to a unique acrylic composition.

Applying adhesive wallpaper with the appropriate paint can greatly improve the longevity and aesthetics of your walls. The best paints for this task are usually acrylic and latex. They provide a clear, smooth surface on which the wallpaper adhesive can adhere with efficiency. Compared to other paint types, these paints dry quickly and are less likely to cause problems like peeling or bubbling.

Make sure the painted surface is completely clean and dry before applying wallpaper. Any imperfections, grease, or dust can reduce the adhesive’s performance. To make the wallpaper glue stick better, you might need to give the surface a light sanding to give it a slightly rougher texture. Additionally, it’s imperative to give the paint time to cure completely; this typically takes a week. If you rush this step, the outcome might not be good.

When the time comes to apply the wallpaper, carefully follow the manufacturer’s instructions. Make use of a premium adhesive made specifically for the wallpaper type you have selected. Smooth out any wrinkles or bubbles as you go, starting at the top and working your way down. During this process, taking your time will guarantee a polished finish that will last for many years.

In conclusion, when applying wallpaper, carefully priming your walls and selecting the appropriate paint can make all the difference. It is possible to attain a smooth and appealing outcome that elevates the décor of your house with patience and attention to detail. Recall that the most important steps are to choose the right paint, prepare the surface thoroughly, and carefully apply the wallpaper.
