Grasscloth’s woven fibers add natural texture, but they also make the wall beneath them especially important. Unlike many printed wallpapers, grasscloth can’t disguise bumps, seams, or uneven patches; its texture may draw attention to them. Proper preparation gives the material a stable, smooth surface and helps the finished wall look consistent. Before installation, inspect the entire area, repair damage, address rough spots, and choose a primer suited to wallpaper and your wall condition.
Inspect the Entire Wall
Remove existing wallpaper and loose paint, then look across the wall in daylight or with a work light held at an angle. Side lighting can reveal ridges, dents, patched areas, and raised paint edges that are easy to miss when viewed straight on. Check corners, areas around windows and doors, and the wall near baseboards, where old caulk or repairs often leave uneven transitions.
Run your hand over the surface to find texture that your eyes might miss. Mark cracks, nail holes, peeling areas, and rough seams with a pencil. If you find active moisture, mold, or a recurring crack, address the underlying problem before covering it. Wallpaper can conceal a defect temporarily, but it cannot stabilize a damp or moving surface.
Repair Damage Before Smoothing
Scrape away loose paint and remove old adhesive residue so repairs can bond to a firm surface. Fill nail holes and small dents with an appropriate wall compound, applying it slightly beyond each edge. For cracks, remove loose material and use a suitable repair method for the crack’s size and cause. Let each repair dry fully according to the product directions before sanding.
Sand repaired spots until they blend into the surrounding wall, then wipe away dust. Use a wide putty knife or straightedge to check for remaining ridges and hollows. Broad, shallow irregularities may need another skim coat rather than repeated spot filling. If the wall has extensive damage or unevenness, consider professional resurfacing; grasscloth’s texture will not reliably hide poor repairs.
Create a Smooth, Consistent Surface
Grasscloth usually looks best on a wall that is smooth, clean, and uniform, not necessarily perfectly polished. Remove raised paint edges, dried compound, and old adhesive lumps. On previously textured walls, determine whether the texture can be safely removed or needs a skim coat. Do not sand paint that may contain lead; follow local guidance and use a qualified professional when the coating’s age or condition raises concern.
After sanding, remove all dust with a vacuum and a clean, slightly damp cloth if appropriate for the wall surface. Let the wall dry completely. Check it again with angled light and your hand. Dust, loose particles, or a damp surface can interfere with primer and adhesive, while even small raised defects may cast shadows beneath the woven material.
Prime and Confirm Readiness
Apply a wallpaper primer recommended for the wall and the installation system. Primer helps create a consistent surface, supports adhesion, and can make future removal easier. Follow the manufacturer’s instructions for application and drying time. Avoid substituting ordinary paint without checking compatibility, and confirm that the primer is suitable for the wall’s existing finish and any repaired areas.
Before installation, make sure the wall is dry, clean, firm, and free of visible dust or loose paint. Resolve any remaining surface defects rather than expecting the grasscloth to conceal them. Because natural fibers can vary in color and texture, discuss the wall condition and material layout with your installer in advance. Miami Grasscloth Co. can assess preparation needs before installation.
Careful wall preparation is essential for a clean grasscloth installation. Repair damage, blend patches, remove raised texture, clear away dust, and apply a compatible wallpaper primer. If the wall has moisture issues, extensive unevenness, or uncertain coatings, get advice before covering it. Contact a qualified installer to review your wall and plan the preparation.
