Oriented strand board (OSB) is a multilayer construction material. The main component is glued and compressed wood. The surface of oriented strand board must be prepared very accurate, before the applying of liquid wallpaper we strongly recommend to sheathe the wall with gypsum boards and then to prepare the surface for gypsum boards. At the market you can find OSB’s that are already sheathed with gypsum boards.
If it is not possible, the surface of OSB must be plastered (about the right type of plaster is better to ask a manufacturer of OSB). Than the surface must be primed with the original SILK PLASTER primer or with the primer GF-021 and then covered with white mat paint. After that you can apply liquid wallpaper.
Because the composition of OSB can be very different depending on the manufacturer, we recommend you to apply SILK PLASTER at the small area at first and then, if the preparation of the surface was done correct, to continue the application to the rest of the wall.
Gypsum boards are currently widely used in the construction of interior partitions. The sheets are fixed with the screws and joints are leveled with plaster mixtures.
Plastering places of only sheets joints is the most common mistake in for the liquid wallpaper application. Becuase it may result to manifestation of the joints places after Silk Plaster applied on the wall, especially if you use light color of Silk Plaster. That is why it is important to putty the whole wall, even though the gypsum boards are very flat, it is important to make sure that joint places are the same white color as the rest of the wall. Then don`t forget to coat the wall with white mat paint.
Places where rust may occur (bolts, screws, nails, tacks and etc.) should be covered pointwise with oil-based paint to prevent rusting.
Materials used in the construction of old houses, were rather poor quality. Often, it's even uncertain from with materials these walls are composed. Such walls are very insidious because they can cause rust which will lead to yellow spots. To avoid the appearance of rust spots it is important to clean and prepare the surface carefully before proceed with the Silk Plaster application.
Plane surface with plaster/stucco and prime it in 2-3 layers with the original Silk Plaster primer, drying time between layers 3-4 hours. Plane the color with white mat paint.
In the absence of the original Silk Plaster primer then we recommend coating it first with any oil-based paint, white color. Then coat it with usual white mat paint for good adhesion.
It is possible to use other compounds available in the market but before applying liquid wallpaper on the wall it is recommended to test it first on the small surface of the wall.
Totally plane surface with plaster/stucco and prime it in 2-3 layers with the original Silk Plaster primer, drying time between layers 3-4 hours. Plane the color with white mat paint.
In the absence of the original Silk Plaster primer use any waterproof primer or any waterproof mat paint. To choose the best primer option please consult with the seller in your country.
If the concrete wall is initially weak, badly peeling, flaking, use of any materials is initially complicated due to the fact that the adhesion is practically absent. Therefore first it is necessary to apply a standard restorative coating which is well represented by various manufacturers in the market of building materials.
Refers to the details of steel reinforcement / armature, airways and etc. Such places have to be covered pointwise with oil-based paint to prevent rusting.
This technique had been often used before. It is important to prevent the manifestation of the color change ("waterline") after drying of Silk Plaster. In this case, we recommend plaster/stucco the surface and prime it with the mixture of PVA adhesive and any water resistant mat paint for front walls (masonry paint) in proportion 1:3. Please, apply 2-3 layers of the primer till you get homogeneous white color on the wall.
Such materials are often used locally, in places of doorways, arches, entresols and etc.
Liquid wallpaper can be applied on the wood surfaces only after you make sure that they will not deform from the moisture, i.e. fixed properly. Moreover, it is worth considering that the thinner the sheet, the most likely its deformation.
To protect Silk Plaster from these surfaces before its applying, use Silk Plaster primer in 2-3 layers, followed by mat paint or any waterproof primer which is recommended by the seller.
In the absence of the original Silk Plaster primer or waterproof primer then we recommend coating it first with any oil-based paint, white color. Then coat it with usual white mat paint for good adhesion.
