A: Classic Shiplap can be installed on a flat, clean, dry, and structurally sound surface. It is recommended that all walls be tested with a sample prior to full installation. Heavy textured walls like knockdown or popcorn walls will require a skim coat application or sanding and scraping prior to installing. All other textured walls like crows feet, orange peel, smooth or swirl will should not require additional prep work.
Q: Can Classic Shiplap be installed on ceramic tile?
A: Classic Shiplap can be installed on clean ceramic tile. Waxy, wet, dusty and dirty surfaces are the only surfaces that would cause adhesion issues.
Q: Can Classic Shiplap be installed over wallpaper?
A: Clean, Smooth, well-adhered wallpaper: This can be a base for Classic Shiplap. The installer must make sure the wallpaper is clean and firmly bonded to the wall before applying the Classic Shiplap to the wallpaper.
Embossed wallpaper: The adhesive on the back of the Classic Shiplap is 1/32" thick. If the embossing on the wallpaper raises out more than that it is possible that the Classic Shiplap adhesion will be interrupted every time it goes over the embossing. This could result in less than a firm bond. The installer will need to test bond strength with several planks to ensure adhesive bond strength to the embossed wallpaper before proceeding with the entire installation. If bond strength is not sufficient, the wallpaper will have to be removed prior to installing the Classic Shiplap.
Textured wallpaper: should be removed and the base wall cleaned with trisodium phosphate ( TSP) before installing Classic Shiplap. To remove wallpaper there are steamers or wallpaper removal solutions available. These items plus the TSP cleaner are available in hardware stores or home centers.
