It is imperative to prepare walls prior to applying liquid wallpaper in order to achieve a smooth and durable application. Selecting the appropriate primer is a crucial step in this process. The final result’s durability and the liquid wallpaper’s ability to stick to the surface can both be greatly influenced by the primer you use.
Primers are different for different types of walls, so it’s important to choose one that works for both your wall type and the particular requirements of liquid wallpaper. Using the right primer will help you avoid problems like uneven application or poor adhesion, resulting in a finish that looks professional.
To assist you in making an informed choice for your project, this article will walk you through the different types of primers that are best suited for treating walls prior to applying liquid wallpaper.
| Primer Type | Key Benefits |
| Acrylic Primer | Dries quickly, seals porous surfaces, and provides a smooth base for liquid wallpaper. |
| Adhesive Primer | Enhances adhesion, especially on difficult surfaces, ensuring the liquid wallpaper sticks well. |
| Quartz-Enhanced Primer | Adds a slight texture to the wall, improving grip for the liquid wallpaper. |
| Universal Primer | Suitable for various surfaces, balances absorption, and ensures an even application of liquid wallpaper. |

When applying liquid wallpaper, using a primer strengthens the wall surface’s adhesion to the decorative coating. The following issues can be resolved with the use of this material:
- increase the adhesion of the base to the finish;
- achieve uniform application and uniformity of coating;
- strengthen the base;
- prevent the formation of mold and mildew;
- improve the appearance of the surface;
- increase the service life of the surface;
- level the base and eliminate irregularities.
An excellent primer fills in pores and microcracks. This reduces the amount of liquid wallpaper used and facilitates use.
Which primer to choose for walls under liquid wallpaper
Not only is a primer necessary to improve the coating’s degree of adhesion to the base. Its primary function is to keep water out of the building.
Selecting a primer that is of superior quality requires you to prioritize materials that exhibit a high degree of hydrophobicity. Processing ought to be done in two or three layers.
Under liquid wallpaper, the following primer types should be used:
- Acrylic – considered the best option. They are easy to apply, dry quickly and are evenly distributed.
- Deeply penetrating – perfectly absorbed by the base. After the material dries, a high-strength waterproof film is formed. An important advantage is the ability to smooth out the imperfections of the base.
- Quartz – made using quartz dust. The material makes the surface slightly rough. This helps to apply the liquid decorative coating more efficiently.
The kind of surface you intend to finish must be considered when selecting a material. Products for specific types of bases and universal mixtures are available from modern manufacturers.
The order of work when preparing walls for liquid wallpaper
If you choose to prime the walls by hand, you must heed the guidance of skilled artisans. You must first get the base ready.
The following actions are advised in order to accomplish this:
- Remove old finishing materials from the walls – paint, wallpaper, whitewash, plaster. It is also advisable to remove plastic and metal fasteners.
- Seal up all potholes, cracks and holes. Protrusions larger than 2 mm need to be leveled. If this rule is violated, the consumption of liquid wallpaper increases and the quality of the finish deteriorates.
- Treat the walls with an antiseptic composition. You should also apply a deep penetration primer. This should be done in at least 2 layers, observing an interval of 3 hours. Thanks to this, it is possible to make the base more durable and resistant to the influence of external factors.
- Apply thick putty to the surface. It can be left white or add a colorant of the same color as the wallpaper.
General requirements for the work surface
It needs to be ready before applying liquid wallpaper to ensure the best possible surface. It must therefore fulfill the following specifications:
- The base must be made as durable as possible. There should be no paint residue, cracks, or traces of plaster on the walls.
- The coating should have a low level of moisture absorption. Otherwise, the surface may suffer from excess water, and it will not be possible to apply liquid wallpaper.
- Color stability is of great importance. The walls should be of such a shade that it does not show through the liquid wallpaper.
The walls must be properly prepared for the ideal outcome. Apply putty and primer, remove the old coating, and fix any cracks.
Technology for applying primer to various surfaces
It is important that you adhere to the directions when applying primer. Every task should be completed in an environment with low humidity. The ideal temperature range for the room is +5 to +25 degrees. Higher values cause the soil to dry out faster and prevent it from being absorbed deeply enough.
The base material and soil composition have an impact on the technology used to apply the material. It is necessary to dilute a dry or concentrated mixture before creating a solution out of it. The final mixture needs to be sufficiently blended to achieve homogeneity.
The adhesive primer needs to be mixed extremely well. One of the fillers in it is quartz, and it sinks to the bottom.
The following should be taken into account when priming the surface:
- Pour the prepared solution into a paint tray.
- Apply an even layer of the substance to the wall. This can be done with a roller or brush.
- Apply a second layer after the first one has dried.
- Do not begin subsequent finishing earlier than in a day.
Painted walls should be primed using acrylic impregnations. Oil-based paints are appropriate for surfaces that can be impregnated with adhesive materials. Sandpaper should be used to pre-clean the surface.
A deep penetration primer needs to be injected into both plastered and concrete walls. At least four hours pass between each of the two times this is done.
Porous surfaces are suited for a bonding primer. The flaws must then be fixed using a gypsum mixture. You can then apply the primer evenly.
Plasterboard walls require the following preparation steps to be completed:
- prime 2 times;
- fill up irregularities and depressions with putty;
- glue the joints of the sheets with serpyanka and putty;
- apply a continuous thin layer of putty to the walls and dry;
- cover the base with a primer in 2-3 layers.
Wooden surfaces have high absorption qualities, which should be considered when preparing them. In addition, it is prone to deformation and is frequently attacked by parasites, mold, and fungi.
It is advised to use a deep penetration acrylic primer on wooden walls. It fortifies the coating, lessens the surface’s absorption of water, and keeps it from swelling. Insecticides, fungicides, and antiseptics should all be components of the primer’s composition. A primer should be applied to the walls in two to three layers. Observing technology pauses is essential for drying the earlier layers.
Selecting the appropriate primer is essential to getting a smooth and long-lasting liquid wallpaper finish. It guarantees good adherence, evens out the surface, and gets the walls ready for uniform absorption of the liquid wallpaper.
Choose a primer made especially for the type of wall you have and the type of liquid wallpaper to avoid common problems like peeling, uneven application, or inconsistent color. Your liquid wallpaper will look better in the end and last longer on a surface that has been prepared properly.
In the long run, using the right primer to prepare your walls will save you time and effort and yield a beautiful, long-lasting finish that lives up to your expectations.
Prior to applying liquid wallpaper, selecting the appropriate primer is essential to guarantee a smooth and long-lasting finish. To improve wallpaper adhesion and avoid peeling or uneven texture, the best primers should produce a stable, slightly rough surface. Primers for different types of walls may need to be used, but the main objective is always to provide a well-prepared base that will aid in the best possible adhesion and appearance of the liquid wallpaper.
