Frogtape masking tape is designed for use on a variety of surfaces. For best results, ensure the surface is clean, dry, and free of grease, oil, or other contaminants. The PaintBlock technology in this tape reacts with emulsion paint to form a micro-barrier that seals the tape edges, making touch-ups easier. This tape is resistant to ultraviolet and is designed to keep paint out and lines sharp. Remove the tape immediately after painting for the best results.
