Wanting multi-coloured walls?
Masking tapes work best with acrylic and latex paints. Choose the width you require. Ensure the surface is clean, dust-free and dry for at least 24 hours. Pull the tape off the roll slowly to avoid stretching and gently apply along your marked areas. For longer strips either have someone help you to keep them from twisting or attach across an open door or frame.
Remove the tape before the paint is fully dried to avoid a ridge along the paint line by slowly pulling it over itself at a greater than 90 degree angle. Practice first for best results.
