Hanging Wallpaper over paneling, concrete block and textured walls

 wallcovering tips

4. Lining Papers or Wall Liners.

Lining papers are used to bridge over grooved paneling, cement unit, cinder block, and similar surfaces before hanging new wall covering. These would otherwise be wall surfaces not appropriate for wallcovering because of the extreme texture.

Surface Preparation.

Paneling should be cleaned with trisodium phosphate and rinsed well. Allow to dry. Sand slightly with medium sandpaper. Size with Uniprep Prepcoat. On cement block walls, chip off protrusions of mortar or they will show through. Size masonry with Wall Prep Multi-Purpose Interior Latex Primer (new block may need 2 coats).

NOTE: Deeply grooved paneling,block walls and sand painted (orange peel) walls may need to be spackled or skim coated. Wall liner will not make all walls look perfect. Caution : Below grade blocks walls tend to have condensation problems in summer months. The moisture encourages mildew growth, and therefore we discourage the use of wallcoverings over below grade block walls.

Application Tips.

Apply heavy duty liners horizontally over grooved paneling, vertically on cement unit. Use heavy duty vinyl adhesive. Allow booking time of ten minutes. DO NOT USE a smoothing brush as this may push the wall liner into the grooves. Instead, use a plastic vinyl smoother. Apply the pressure vertically with the grooves.

This will allow the paper to dry out out and thus bridge over.

Allow liner to dry 24-48 hours. Prime and size in one step using Wall Prep Multi-Purpose Primer. Let dryovernight. Hang new wallcovering selected to disguise any imperfections (from above through #2).
