Instructions for application

Aug 21, 2011

1. Surface preparation (primering)


1.1. The surface has to be clean and dry. All contamination, old wallpaper, paint, scratched paint, nails, etc. have to removed

1.2. Before applying the liquid wallpaper, the surface needs to be primered, so that no stains show up on the surface of dried liquid wallpaper later. Stains can be caused by rust, grease, mold, old glue, etc.


ATTENTION: Do not primer with Boro Contact or any other silicon-based primer!!!


We recommend the following primers:

А/ when the surface on which you will apply the liquid wallpaper is clean and/or plastered with plaster, use an impregnating primer AK 11(manufactured by Lakprom)

Characteristics of the AK11 impregnating primer, straight from the manufacturer:

• It is designed for primering of gypsum plasterings, plasterboard walls, sandy plasterings, cement and lime-cement plasterings, bricks, cellular concrete, gas-filled concrete and mineral bases.

•It has a good penetration quality and it stabilizes unhealthy surfaces, increases the durability and strength of the applied plastering of choice.

• It is perfect for enclosed spaces. No organic dissolvents are emitted.

Dries in: 2 hours at room temperature

Covers: 10 m2/l ( 70-90 g/m2 )

B/ when the surface for the liquid wallpaper is very dirty or the wall color differs greatly from the liquid wallpaper, use SEALENT PRIMER (manufactured by Lakprom)

Characteristics of the sealant primer, according to the manufacturer:

• It is designed for primering and sealing very dirty surfaces, which are impossible to clean.

• Assures a good adhesion between the dirty surface and further coatings.

• Isolates from finishing coatings from surfaces which nicotine residues, stains and oil build-ups. Guarantees long-lasting coverage and prevents the migration of stains from layer to layer.

Dries in: 2 hours at room temperature

Covers: 80-100 g used per m2


In case of old or multilayered previous plasterings, use the sealant primer first and then, after it has dried, cover with the impregnating primer.

Please note any rust spots. That may mean that right under the plastering there is some rusty armature. In order to ensure that none of this rust breaks through to the liquid wallpaper layer you need to do the following: cover every rusty sector with 2 coats of sealant primer and cover the area around the spot with white paint (2 coats). Of the sector cannot be sealed in this way – for example, if the armature is sticking out – you may use some aluminum foil and paint it white white paint. That way, no stains will appear on the finished wall. Also, every single metal object needs to be removed from the wall (nails, screws, etc.) before applying the liquid wallpaper. After the wall has dried completely, they may placed back.


The liquid wallpaper is applied after the primered surface has dried completely.


2. Work instructions

Please note that the amount of water that is needed for 1 kg of cellulose from the standard pack is 6 liters, while 1 kg of cellulose from a box requires 4.5 – 5 liters of water.

I. Standard pack – 2 kg


1. Dump the whole pack in the plastic container, which can hold enough material for covering a single wall preferably. Dissolve the contents of the glue packet (250 g) in 12 l of warm and clean water (6 l per kg). Stir and wait 10-15 minutes for the glue to completely dissolve. If needed, knead using hands to help dissolve lumps of glue. The mixture is then added to the cellulose. Stir with a mixer at low RPM until a homogeneous mixture is achieved. Try not to disturb the entirety of the cellulose strands in order to preserve the integrity of liquid wallpaper. IF you do not have a mixer, knead with your hands, similarly to dough, for 5-6 minutes.

2. The mixture is left to sit a minimum of 3-4 hours, but not more than 12 hours. Then stir again using your hands or a mixer at low RPM.

3. When preparing the mixture for the next wall, use the remainders for the previous mixture.

4. The finished mixture is applied to the wall with a plastic or stainless steel mortarboard, similarly to ordinary plastering. Keep the mortarboard at an angle of 10-15 degrees to the wall to allow for easier mixture spreading. The necessary thickness of the layer is determined by the bumps in the wall and/or your taste.

Note: If the mixture seems tough to apply to the wall or the layer is not the correct thickness( usually 1-2 mm), add some water to improve the consistency of the mixture. Try it on smaller amounts of the mixture instead of the whole batch.

II. Box – 1 kg

The packet of glue that is in the box is added to 4.5 liters of water, stirred and then left to sit for 10-20 minutes until it completely dissolves. This mixture is added to the 1 kg of cellulose liquid wallpaper from the box. Stir well and let the new mixture sit for 3-4 hours. After that, stir again and add about 0.5 liters of water (for Liquid wallpaper 67 and 72, add the additional water slowly and only if needed, since they require less water than other models).

Note: Always measure carefully the amount of water added to the dry wallpaper material.

For example:

If you are using one Standard Pack with 1 box, the amount of water needed is 2×6 l + 4.5 l = 16.5 l. The two packets of glue must be completely dissolved in that amount of water.

If you are using decorative additives, add them to the dry material and stir well, to achieve a consistent effect. If you are using the brocades additive, add it to the water, so that it spreads well.


III. Finishing touches

1. In order to cover up the tracks of the edges of the mortarboard, after the surface has dried a little bit, go over the wall with a rubber roller. Use no force and dip the roller in water periodically. If you do not have a roller, use your hands, but make sure to wet them first.

To save yourself some time, use a stainless steel mortarboard with rounded edges, so that there is no need to smooth out the wall.

2. It is advised to cover the whole wall with the material from one mixture and without any significant interruptions during the application of the material. This way, you will avoid having “seams” between the wet and dry materials.

Even if you do not have any experience in liquid wallpaper decoration, following the work instructions will ensure that you have a high quality finish of desired surface.


* It is advised that you buy from just one lot of liquid wallpaper.

*If the hue of different lots is different, it will require you to mix the boxes together to achieve a consistent color.

* The time for the liquid wallpaper to completely dry is over 48 hours.

* It is advised to air out the room during the drying process, provided outside air temperatures are above 0 degrees Celsius. If the outside air temperatures are below 0, it is NOT advisable to leave the room aired for too long.


* If you want to achieve the effect in the above picture, use a relief roller 4-5 hours after the plastering is complete. Periodically dip the roller in water and the then squeeze the excess water.

3. Achieving a washable liquid wallpaper

If you want to use liquid wallpaper as a plastering for a room with a lot of human traffic, you can seal the material so that a washable surface is achieved. It will be tough and last very long. After the surface has dried completely, use a 1-to-1 mixture of glue C-200 and water. This way of “sealing” the surface is useful for entrees, corridors in public buildings, walls in bars, shops, hotels, etc.

Although the thus sealed liquid wallpaper loses its hygroscopicity, it retains its heat isolation properties and increases its possible applications – bathroom walls, laundry rooms, balconies and terraces (if covered), etc.
