Oil paint features

This type of material is created using a traditional olifa, which can be:

  1. Natural.
  2. Artificial.

The pigment that is most readily available in the pier is added first, followed by the addition of the remaining compositions. To achieve the necessary density, the paint is diluted.

These coatings have the following benefits:

  1. High strength.
  2. Durability.

To adhere with your own hands, paint on wallpaper, you must ascertain its classification:

  • If the surface of the wall is not shiny, It can not be erased with a wet rag, most likely, water-dispersion paint was used to apply the coating. It will not work to soak it, but it is possible to remove it with a spatula and is not too difficult.
  • The situation is easier with whitewashing. To determine it, you only need to rub with your hand on which a white plaque should remain. You should not paste over a whitewashed wall with chalk or lime, the coating will not hold on such a surface. But if you remove all unnecessary things with a wet sponge or brush, the panels will hold quite securely.
  • Enamel and oil paints do not react to water at all, they have a smooth, shiny surface.

Advice: Avoid adhering wallpaper to oil paint that has already been applied. However, this is achievable if specific surface preparation techniques are followed.

It’s critical to understand how to update your walls properly if you want to work with oil-painted surfaces. This tutorial will take you through all the necessary steps to guarantee a smooth, long-lasting finish and correct wallpaper adhesion to oil paint.

How to prepare a surface for gluing wallpaper with oil paint applied to it

Every surface needs to be thoroughly examined before applying wallpaper adhesive over oil paint.

  • Identify places where there are cracks, peeling layers, which are often removed along with the putty (see. How to remove putty from walls and how long it takes) or plaster. Such defects cannot be left.
  • Be sure to remove all nails, protruding elements, dismantle the baseboards.

Advice: The surface needs to be thoroughly cleaned if, following rough preparation, half or more of the existing coating was removed. Should the majority of the walls exude confidence, you may employ specific preparatory methods.

  • Before gluing wallpaper on oil paint, the wall needs to be sanded, as shown in the photo. It is known that the adhesion of oil paint to another coating is very poor.

Roughening up a smooth surface is necessary to improve adhesion.

  • Coarse-grained sandpaper should be used on all walls.
  • The walls are treated with a deep penetration primer (see. Types of construction primers and their scope of application).
  • The solution is left to dry for 24 hours.
  • Compare the cleaned areas with gypsum-based putty (see. Gypsum putty: its advantages and problems of use).
  • The surfaces are washed with soapy warm water. This solution will wash off the fat, which will allow the paper to stick better.
  • To enhance the properties of the composition, a small amount of PVA glue should be added to the wallpaper glue.

Advice: Apply a thin layer of water-diluted PVA glue to the wall before gluing wallpaper. Allow the glue to "set" a bit, but don’t wait for it to dry completely before starting to glue.

How to choose the right glue

The correct adhesive is chosen prior to adhering wallpaper.

Purchasing it is preferable for wallpaper with a high mass:

  • Even for thin, single-layer material, a mixture intended for vinyl wallpaper is taken. These can be:
  1. Bustilat;
  2. Moment;
  3. Methylan.
  • If the price suits you, it is better to buy PVA glue. The composition is used:
  1. in pure form;
  2. diluted with water, in a ratio of 1:1.

How to prime surfaces

The primary goal of surface preparation should be to get rid of oil paint’s poor absorption capacity in order to increase the adherence of paper wallpaper on the wall.

Guidelines for completing the task:

  • Purchase the primer "Concrete Contact" or quartzite.
  • The walls are washed and dried.
  • Apply the composition, the layer thickness is about 4 millimeters.
  • After drying the surfaces are putty with ordinary putty.
  • The dried layer is again covered with a primer.
  • The selected wallpaper is glued to the dried walls.
  • The primer can be made independently from available and inexpensive materials, which can be: PVA glue and
  • alabaster.
  • water is poured into a container;
  • alabaster is added little by little, constantly stirring the mixture;
  • after the composition reaches the consistency of sour cream, PVA glue is added, while the ratio of the compositions is taken: one part glue – three water.
  • Well-washed walls are coated with a homemade emulsion and left to dry.

Some tips for gluing wallpaper

  • To increase the strength of the wallpaper, you need to cover the canvases and walls with glue.
  • Drafts must not be allowed during the work, and after its completion. Windows and doors are tightly closed until the walls are completely dry.
  • Do not glue wallpaper in hot or cold weather, or in high humidity.

Careful planning and the appropriate technique are necessary for wallpapering over oil paint to be successful. The wallpaper will stick better and last longer if the surface is properly cleaned and sanded. Ignoring these steps can result in bubbling and poor adhesion, which will reduce the effectiveness of your effort.

Another important step in sealing the oil paint and preparing the surface for the wallpaper is applying a high-quality primer. This primer stops any possible bleed-through of the previous paint in addition to improving adhesion.

Applying wallpaper will be seamless and durable if you follow these instructions. The preparation stage will pay off with a beautifully finished wall that complements the decor of your room if you are patient and meticulous.
