Instructions for working with liquid wallpaper
In this article we will try to answer many questions that often arise when you first meet with liquid wallpaper. The liquid wallpaper technology described below covers a wide range of issues.
We often meet with the questions: “How to glue liquid wallpaper?”, Or, better to say, “How to apply liquid wallpaper?” practical guidance covering all areas of their application: the preparation of various types of surfaces, the preparation of liquid wallpaper for application and, of course, the technology of applying liquid wallpaper.
Preparation of walls for the application of liquid wallpaper
If the interior uses liquid wallpaper, the design of this room will be different variety, due to the fact that they allow you to use the widest range of techniques and methods of finishing all possible surfaces. Preparing walls for applying liquid wallpaper is easier than for most other finishing materials. However, at the same time, it is necessary to accurately follow the instructions prescribed in the instructions for the material.
Often found surfaces:
- Concrete surfaces, cement-sand plasters, clay plasters.
These surfaces should be coated with white or colorless acrylic primer, then to putty with a starting gypsum plaster, which, after drying, should be covered again with white or colorless acrylic primer.
- Gypsum plasterboard.
The technology of working with gypsum plasterboard provides for the treatment of the entire surface with a gypsum plaster. We act on the technology: we cover with white or colorless acrylic primer, then putty with a finishing or starting gypsum plaster, which after drying, again covered with white or colorless acrylic primer.
Rare found surfaces:
- Wooden surfaces, wood fiber and chipboard. When preparing materials with wood base (most often it is chipboard, fiberboard, MDF, OSB), the surface should be opened with alkyd enamel. After drying, you can apply liquid wallpaper.
- Metal surfaces – Most often it can be pipes or steel structures embedded in the wall. Steel reinforcement of reinforced concrete structures projecting close to the surface of the wall can also occur. This surface should be opened with alkyd enamel.
It is important to note:
Before preparing for the application of liquid wallpaper, it is necessary to remove old rolled wallpaper from the surface, completely wash off the whitewash, and prepare the parts of the steel reinforcement protruding to the surface, as well as other metal surfaces - paint over with alkyd enamel.
When choosing acrylic primer, it is necessary that after drying it is colorless or white. Sometimes manufacturers of acrylic primer, in order to give them specific properties, can add copolymers to them, which in turn impart color to the acrylic primer and paint the finished coating in an undesirable color. It is important to choose the right acrylic primer.
The use of white or colorless acrylic primer is mandatory at each stage of the preparatory work associated with the putty, because when applying liquid wallpaper, each square meter of the coated surface contains 1.5-2 liters of water, and the correct use of acrylic primer before puttying, and before applying liquid wallpaper, allows you to avoid unwanted peeling of the putty layer from the surface to be coated.
The surface on which liquid wallpapers are applied is not necessary to be made smooth (as it’s the case with roll-wallpaper or for painting). Such a surface may be rough - for this reason, it is enough to putty with start gypsum plaster, and there is no need to additionally make finishing putty, and even more sanding it. Within the thickness of the application of liquid wallpaper, which is 1-1.5 mm, they will hide all the irregularities and roughness of the coating.
For applying liquid wallpaper, the prepared surface must be dry and clean.
It is also necessary to remind that our specialists created liquid wallpapers, the technology of which allows covering surfaces of almost any curvature.

- Preparation of liquid wallpaper for use
In order to prepare liquid wallpaper for use, it is enough to pour them into a clean plastic vessel (bucket) and fill them with warm water at a temperature of 40-50 ° C (warm water contributes to the proper dissolution of the adhesive component without the formation of lumps). After that, the soaked mass must be manually mixed just enough to leave no dry areas in the mixture. It is undesirable excessively active mixing, as well as mixing using a mixer, because this will lead to the fragmentation of color fractions, and as a result of the distortion of the color-texture laying scheme. The wetted mass should be tightly covered with a lid or plastic bag to prevent evaporation of moisture during the soaking process. Liquid wallpaper must be soaked for at least 8 hours. In the wetted state, liquid wallpaper can be stored at room temperature without losing its properties for up to 5 days, while maintaining its adhesive properties. Immediately before applying, wetted liquid wallpapers must be mixed by hand to lift liquid from the bottom of the vessel.
- Applying liquid wallpaper
Unlike most modern finishing materials, liquid wallpaper, the application of which does not require special skills of a painter or plasterer, can be qualitatively applied by anyone who has a desire to practice that skill.
In wetted form, liquid wallpaper is a viscous plastic mass. It should be noted that the liquid wallpaper is safe for health, both in dry form and soaked.
The process of applying liquid wallpaper does not require special skills, which is why they are classified as DIY or "Do It Yourself" materials. The task of applying is reduced to smoothing the plastic mass over the surface to be coated.
The most convenient tool for applying (smoothing) liquid wallpaper is a plastic trowel. It looks like a rectangular plastic board, usually with a size of 130 x 270 mm with a “90⁰ banded” shaped handle.
Smoothing on the surface must be done in a straight forward motion of trowel. Movement can be made in any convenient direction. At the end of the movement, the trowel must come off the surface completely. It is necessary to avoid continuous circular movements.
The thickness of the application for the correct consumption of material should not exceed 2 mm in the plastic phase of liquid wallpaper (when dried, the volume decreases to 1-1.5 mm). When applied too thin - there will be gaps in the applied layer, which must be corrected with the next reverse movement of the trowel. It should be noted that the application of a thicker layer than 2 mm will affect only the material expense and the drying time, but not the quality of the finished coating. Moreover, if the liquid wallpaper is applied with a layer thicker than 2 mm, we recommend maintaining the same coating thickness over the entire surface. Thus, after drying, we get a uniform coating texture on the whole plane.
Usually necessary for applying the skill is developed during the first 15-20 minutes of work, after which, in the future, it will enhance and improve.
We recommend that the first coating experience to be worked out on a flat, straight section of the wall, and it is advisable to cover the wall from right to left, provided that you put the trowel in your right hand - this will ease the application and avoid touching the finished coating with your left shoulder.
It is necessary to apply one plane with material from one batch, from corner to corner. Compliance with this condition ensures a uniform color-texture pattern on the plane to be coated.
The work on the application of liquid wallpaper also needs to be completed, bringing the coating over the entire width to the corner, in other words, having completed the entire plane. This eliminates the need to soak the dried edge of the coating to continue the work, and also guarantees that the color-texture pattern on the plane to be covered will be uniform.
In the process of applying, and after its completion, the room in which the application of liquid wallpaper was made must be ventilated. Active ventilation contributes to the rapid evaporation of moisture from the newly applied coating. On average, drying lasts two days. If it is cold and damp outside, we recommend actively use additional heating in the form of fan heaters. The flow of warm air can be directed directly to the applied liquid wallpaper - this significantly speeds up the drying process, but it is also necessary to ventilate the room from time to time.
Recommendations on caring and usage of liquid wallpaper in interior. Introduction to BIOPLAST wallpaper’s samples range.
During its lifetime period, liquid wallpaper BIOPLAST does not require special care. They have the antistatic property, i.e. lack of electrostatic charge and as a result - do not attract dust.
If, nevertheless, excessively dusty work was done in a room with a coating of liquid wallpaper, then practice shows that dust that has gotten onto the walls can be simply removed with a vacuum cleaner.
Liquid wallpaper is one of the few decorative finishing materials that allows the maintenance of the coating, leaving not any sign of this repair. The fact is that the adhesive component in the liquid wallpaper is CMC, showing the properties of convertibility. With abundant soaking, for example, when preparing liquid wallpaper for application, CMC is plastic and adhesive. When dried, it becomes a solid substance and binds all the components of the liquid wallpaper. Lifetime does not affect this property.
Thus, abundantly soaking the coating of liquid wallpaper, we can make it plastic, and by drying we remove this property.
In practice, it looks like this. Imagine that the coating was mechanically damaged. To repair a damaged area, it is sufficient to locally soak it with water. Within a few minutes, the coating on the wetted area will become plastic. And just like when applying the coating, we smooth the plastic mass with a plastic trowel and leave the repaired area to dry out.
If the coating of liquid wallpaper is stained, we use the same property to restore it - the damaged area is soaked locally and the contaminated part of the coating is removed in the plastic phase. In place of the removed fragment, the required amount of clean material is applied and smoothed. As a rule, an unused residue of a mixture of liquid wallpaper, dried, for easy storage, in case of such repair, is used as a material for restoration.
For any decorative coating, sooner or later there comes a stage when, after many years of its lifetime, it must be dismantled. Liquid wallpaper can even make this stage of work with them easy. And here again we use the property of convertibility. It is most convenient to soak large surfaces with a “fur roller”, i.e. roller with a long nap, previously dipping it into the water. Quickly absorbing water from the vessel, when rolled, the roller quickly gives it to the surface. Soaking the coating in this way, you can easily remove the plastic mass.
