Protecting windows whilst decorating or doing construction work can be a bit awkward. You have to cut sheets of decoarators paper to size, and then attach with masking tape. Sometimes it falls off, and sometimes the masking tape leaves residue. With Interior Liquid Tape, things are a lot easier. Simply apply Liquid Tape with a brush, roller or airless spray gun, and leave to dry. When you are finished, peel it off. Really quite easy.
