Is it possible to glue wallpaper on the painted walls? Stages of preparatory work

When renovating, a common question that many homeowners have is whether to glue wallpaper onto painted walls. Although it may appear like a simple task, careful preparation is necessary to ensure the wallpaper adheres well and lasts.

It’s important to realize that not all painted walls are made equal before starting the project. The success of your wallpaper application is greatly influenced by the type of paint, its state, and the surface of the wall.

You can follow this guide to learn how to get your painted walls ready for wallpaper application. These preparatory steps will help you achieve a smooth, durable finish that will improve the aesthetics of your area.

Stage Description
Inspect the Wall Check the painted surface for cracks, peeling, or uneven areas. Fix any damages before proceeding.
Clean the Surface Thoroughly clean the wall to remove dust, dirt, and grease. Use a mild detergent and water, then let it dry completely.
Sand the Paint Lightly sand the painted wall to create a rough texture. This helps the wallpaper adhesive bond better.
Apply Primer Use a suitable primer to seal the paint and provide a good base for the wallpaper. Let it dry according to the manufacturer"s instructions.
Measure and Cut Wallpaper Measure your wall and cut the wallpaper to fit. Leave a little extra at the edges to ensure a perfect fit.
Apply Wallpaper Adhesive Follow the wallpaper adhesive instructions. Apply it evenly on the back of the wallpaper or directly on the wall, depending on the type.
Hang the Wallpaper Carefully hang the wallpaper, starting from the top. Smooth it out to remove any air bubbles or wrinkles.

How to determine the type of paint?

You can easily identify the type of paint, even if the walls were painted many years ago. In order for the owners to recall the type of paints and varnishes used, the surface is frequently completed on their own. If the work was completed without your input, you will need to take certain steps in order to make the situation more clear.

To accomplish this, wet a napkin with regular water, then use it to wipe the painted surface:

  • When the foam is formed, the presence of the remains of the coloring composition on the napkin, we can safely say that this is water -based paint. It is not necessary to glue the wallpaper on such a wall – the coloring composition can be removed using warm water.
  • If the liquid is pushed away from the surface, then the frozen paint can be removed and rolled up with a spatula. If the material breaks up into separate pieces, then, most likely, some kind of paintwork was used. If the material resistant to mechanical stress is not ripped off and is not excluded, then it is likely that this is a water -dispersal paint.

How to check the surface adhesion?

It’s important to determine the level of adhesion as well as the type of paint the surface is painted before applying wallpaper adhesive to painted walls. The degree of adherence of the prior coating will be crucial.

Standard installation tape is used for the check. It is swiftly torn off after being glued. The coating needs to be taken off if the coloring composition is still stuck to the adhesive tape. You can safely adhere the wallpaper directly to the surface if it remains motionless where the gluing tape is.

Crucial! Applying glue wallpaper to walls with mold or fungal lesions is not permitted at all. Such surfaces need to be cleaned, washed, treated with antiseptic compounds, and all previous coatings removed, regardless of their condition, before you glue the wallpaper.

How to prepare a wall that was painted with oil paint?

Is it possible to glue wallpaper onto water-based paint, suggests the guide? We respond to frequently asked queries.

Adhesive wallpaper can be easily applied to oil-painted walls. Vinyl and non-woven wallpaper can also be glued if the audit revealed that the previous coating is of excellent quality and holds well. But one should resist the urge to adhere thick wallpaper.

The following is how the draft surface is prepared:

  1. First, the coating must be treated with a skin to a matte state, due to which the degree of adhesion increases.
  2. Then the wall is cleaned, all pollution is removed from it (you can wash and dry).
  3. Further, processing with primer compositions is required (you can use a primer for applying a primer).
  4. The primer is applied sequentially in two layers. Only after applying the primer and its drying can you glue the wallpaper.

Crucial! It is advised against saving and to use premium adhesive solutions (such as those that include PVA) to apply wallpaper. These solutions can offer the highest degree of wall cling.

Preparation of a wall painted with acrylic paints

Should the wallpaper be placed on a wall that has been painted with acrylic compositions, avoid using skin to clean the grout as the coating is already matte.

However, there will still be some preparation work to be done:

  1. Before gluing wallpaper on acrylic paint, the surface must be washed from dirt, cleaned of dust and dried naturally with the help of ventilation.
  2. Then, as in the previous case, primer material is applied in two layers.
  3. It is also recommended to additionally process the wall using diluted adhesive composition and wait for its drying. After that, you can safely glue the wallpaper – the base is ready for use.

Crucial! If wallpaper is to be adhered to paint (of any kind), a two-layer primer is an absolute necessity. Applying primer material in two layers is recommended.

Adhesive wallpaper can be applied to painted walls, but careful preparation is necessary to guarantee a smooth and durable result. The most important steps are to give the walls a thorough cleaning, sand any uneven areas, apply a primer, and maybe use wallpaper adhesive made for painted surfaces. You can get a polished appearance that adheres well and endures over time by carefully following these steps.

Preparation of a wall painted with water -based paint

Since water-based paints are the least durable, it is crucial to assess the condition of the painted coating before applying any more. You can easily glue the wallpaper if the audit indicates that everything is in order, but not too thick. The tasks are completed in the same order as in the preceding two points.

The guide offers advice on how to apply glue wallpaper on a non-woven basis, including glittering details, preliminary tasks, and expert advice.

It is necessary to fully remove the previous finish before adhering wallpaper if there are any uncertainties regarding the condition of the surface.

Here’s how to get rid of the water-based composition:

  1. The walls are wetted with water, after which the coloring composition is removed with a spatula.
  2. Difficult places are recommended to be treated with chemical solvents or special washing.
  3. In special cases, you can use the surface grinding method.

It is worthwhile to respond in the affirmative when asked if it is possible to glue wallpaper to long, colored walls, but doing so requires skillful surface preparation.

The canvases will not survive more than a few days if the wallpaper is glued on top of the old paint, which peels and vanishes in bits.

If the coloring composition adheres to the wall well and is challenging to remove, even with mechanical means, you can apply glue paper, vinyl, non-woven wallpaper, and other lightweight modern wallpaper types on such a coating.

The process of gluing

If the walls are painted and have remnants of coloring material, adhere the wallpaper; however, the longevity of this type of decoration is called into question. Consequently, it’s critical to follow the above instructions for preparation before adhering the wallpaper.

Gluing for water -based or acrylic paint

In order to complete this work, updating the outdated cladding is advised. To achieve this, a unique 1: 1 primer and solvent mixture is made, which can be applied straight to the painted wall to remove the previous coloring agent. The applied primed material will thoroughly penetrate the structure and guarantee the right amount of adhesion because of this neutralization process.

Crucial! The preparatory step is particularly crucial if adhering wallpaper to water-based paint, as this type of coloring is thought to be the least long-lasting.

Following primer and solvent processing, the wall should air-dry. Applying the primer in two layers is recommended. The wallpaper cannot be glued until both layers have completely dried.

It is advised to use a 1: 1 ratio of regular wallpaper glue and PVA when adhering paintings. The completed glue must be applied to both the wall and the canvases before gluing.

Oil paint

The method by which this work is done will mostly rely on the outcome that the owners hope to achieve.

  • If the wallpaper is planned quickly and not for a long time, then you should not tear off the oil coating.
  • If it is supposed to glue expensive wallpapers that should last 10-15 years, it is strongly recommended to remove the oil paint completely and well prepare the black surface.

In order to achieve the best possible quality when gluing paintings, the wall needs to be treated with a skin when selecting option number one. By creating tiny irregularities through processing, you can improve the adhesion of the canvases to the wall. Following processing, the coating must be primed in two layers and dried one after the other.

If the second option is selected, oil paint is taken off the wall using whatever method works best for you. Typically, the old coating is removed with a metal spatula.

Aligning and priming two layers is also advised before adhering wallpaper to a black surface.

Crucial! It is not advised to adhere canvases straight onto a black surface without first priming them; the wall’s appearance will suffer and the coating will be of very poor quality.

Useful tips

Wallpaper is frequently applied to painted walls; this is a common practice. As we mentioned in earlier points, the wall’s surface needs to be properly prepared before painting.

Additionally, pay attention to these suggestions:

  • For gluing wallpapers, it is worth choosing notable and high -quality glue (preferably from well -known manufacturers). It is important that the adhesive composition has high fastening properties, t.To. The painted surface is not the best option to glue the canvases.
  • You can not glue wallpaper to the surface if it has bright shades. If the canvases are light, then the black coating will be clearly visible through a layer of material, as a result of which the entire aesthetic effect will be lost.
  • After gluing the paintings, it is recommended not to allow drafts and temperature changes in the room for 1-2 days.

If the preparatory work is done correctly, adhering wallpaper to painted walls is not only feasible but can also produce a beautifully refreshed room. Making sure the painted surface is smooth, clean, and primed for the new wallpaper is essential to success. If you take the proper procedures, you can have a beautiful finish that makes your room look better.

Examine the painted walls’ state initially. Paint that is flaking or peeling must be completely scraped off. For the wallpaper to stick properly, the walls must be clean and smooth. Another way to improve the wallpaper glue’s adhesion is to sand the surface to give it a little rougher texture.

Next, it’s imperative to clean the walls. In order to make sure the wallpaper adheres properly, all dust, grease, and dirt must be removed. For this, a straightforward solution of water and mild detergent can be used. Before proceeding to the next step, thoroughly dry the walls after cleaning them with plain water.

Using a primer is a crucial step that you shouldn’t omit. A high-quality primer will increase adhesion and produce an even surface. This will guarantee that the wallpaper remains in place for an extended period of time in addition to making the application process simpler. Let the primer completely dry before moving on.

You can begin wallpapering as soon as the walls are ready. To get the best results, adhere to the manufacturer’s instructions. A professional-looking finish can be achieved with precise alignment and fluid application. It’s worth the time to properly prepare the painted walls so that the wallpaper goes on smoothly and lasts a long time.
