Good masking is the key to sharp, professional paint lines and an overall neat, finished look. A great paint job begins with knowing how to mask properly and how to remove the tape. It also can help avoid rework by preventing paint drips, spatters and accidental brush strokes.
Pull tape off the roll a few feet at a time. Lay it onto surface depressions. Press down as you go. Avoid stretching the tape, as this can cause it to lift up or break.
4. Seal the Edges
Secure the tape by pressing the edge down with a putty knife or a 5-in-1 tool. If the surface is textured, seal the edge of the tape with the existing base color of the wall. This will prevent the new paint color from seeping under the tape.
Remove the tape at a 45-degree angle, and at a moderate speed. Just pull the tape back on itself. If adhesive sticks to the surface, try a 90-degree angle. If paint is pulling up with the tape, try scoring the edge of the tape with a razor blade before pulling further.
