Get crisp, clean lines on your next painting project with FrogTape Multi-Surface Painters Tape. How does it work. It's made with exclusive PaintBlock Technology, a super-absorbent polymer that reacts with the water in latex paint and instantly gels to form a micro-barrier that seals the edges of the tape to prevent paint bleed. The result is a crisp, professional paint line. Designed to work on a variety of surfaces, this professional grade masking tape delivers a performance you can be proud of.
