Surface preparation

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

Material usage: 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

Material usage: 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.
