FrogTape is the only tape treated with PaintBlock technology. PaintBlock is a super-absorbent polymer which reacts with latex paint and instantly gels to a micro-barrier that seals the edges of the tape preventing paint bleed so you get sharp paint lines every time! This tape features medium adhesion and is great for use on cured, painted walls, wood trim, glass and metal (21-day interior use/7-day exterior use). This package contains 45 yards of 1.41-inch wide FrogTape. Caution: Test before use on all surfaces including those with texture. Made in USA.
