Woodchip wallpaper is made from wood fibre in between two layers of paper. Due to the type of material it’s made from it's difficult to remove. Instead people install drywall over it, which becomes expensive. With a sharp scraper, elbow grease and patience you can successfully remove this wallpaper and save yourself money.
Determine when your woodchip wallpaper was installed. Woodchip wallpaper installed prior to 1985 may contain asbestos. If your wallpaper was installed before 1985 contact a professional and have it tested.
Removing any kind of wallpaper is not a clean activity. To protect your floors and moulding, lay a dust sheet. This collects runoff water, paste and wallpaper.
Remove the first layer of paper by loosening a corner and pulling it. This exposes the woodchip material. This does not require any scraping.
Mix the concentrate (wallpaper remover) in a bucket with water (warm preferred). Follow the directions on the bottle for the correct measurements.
Score the remaining wallpaper. This is the hardest part of the process and takes time. Do not get frustrated. Penetrating the woodchip material is a vigorous activity. An additional person to help with this step will speed up the process.
Soak your sponge in the bucket and apply the concentrate to a section of the wall. The more concentrate you apply, the easier it is to remove the wallpaper.
Let the concentrate sit for 15 to 20 minutes. This breaks up the adhesive.
Scrape off the wallpaper using the scraper. Use the scraper lightly so it doesn't damage the drywall. Woodchip wallpaper is much stronger then traditional wallpaper so you may need to repeat this a few times.
Sponge off remaining paste stuck to the wall.
