This textured finish is often described as "orange peel" or "knock-down" texture.It is very common that this texture was applied at new construction and considered the final finish. If wallpaper was applied over this type of textured finish and the texture was not sealed prior to wallpaper being installed, the removal process may damage the texture. The damage occurs because the wallpaper adhesive "cured" over time and absorbed into the porous texture without the benefit of the wallpaper adhesive attaching to a quality primer or sealer. Once moistened with removal solutions, bubbles or blisters can occur. Often the texture may scrape away easily.
Drywall should always be sealed with a wallpaper primer prior to the installation of wallpaper.
If it is necessary to fix the blisters, gouged drywall, torn or delaminated drywall; a penetrating sealer should be applied as the immediate next step towards smooth walls. Draw-Tite is odorless, water based and the ideal product for this application. Draw-Tite will soak through the face of the drywall and penetrate to the gypsum. Once the Draw-Tite dries (1-2 hours) the walls are ready to receive joint compound, spackle, and/or paint.
Typical coverage is 400-600 square feet per gallon. Draw-Tite is a one coat product.
Draw-Tite is also ideal for sealing builder's porous flat paint.
