1. Treatment of wooden surface

Wood Texture Wallpaper

-The moisture content of the wood surface should be no more than 12%.

-The surface should be flat and free from dirt, oil and other filth.

-Use a thin brush with paint to prevent the wood fibers from swelling in water.

-If the wood surface has nail caps, let the nail caps sunk in the wood table and anti-rust paint.

-Patch the joints with atomic plaster, leave to dry and then use latex and water to mix putty, scrape 1-2 times all over.

- Smooth with sandpaper and brush the surface with a protective film.

Note: For smooth, flat, absorbent wooden surfaces, a thin brush of varnish on the surface is sufficient enough to adhere the wallpaper.


2. Treatment of plasterboard surface(with nail holes)

-After drying, apply bandages to the joints.

-Scrape the putty 2-3 times, after drying, sand smoothly, and straighten the corners.

-Brush the base film once.


3. Treatment of old walls

Old Walls

-Chalked old walls cannot be directly glued to the surface with wallpaper.

-Sprinkle water on the surface and then remove the paint and chalking layer with a spatula.

-Brush the interface agent or varnish once after leveling.

-Use plaster or putty to level the wall (for walls with large cracks, apply a layer of fabric before scraping the putty).

Note: For walls that cannot be leveled, use a wallpaper knife to cut small squares on the wall shaped like spider webs, the deeper the scratch the better, the smaller the square the better.
