I’ve been looking for a method to create crisp, sharp edges on canvas. I’ve used standard blue Painter’s Tape in the past, but with poor results and lots of under tape paint bleed. Along comes a new product…FrogTape®. FrogTape® is advertised as the only painter’s tape treated with PaintBlock® Technology. PaintBlock is a super-absorbent polymer which reacts with latex paint and instantly gels to form a micro-barrier that seals the edges of the tape, preventing paint bleed. I decided to conduct my experiment on gessoed cotton canvas. Here are my results:
On the top line, I painted directly over the two different tapes with (1) undiluted Golden’s acrylic tube paint and (2) the same paint heavily watered down. While the FrogTape® was better at preventing bleeding, neither did a good job.
Don’t despair! I discovered a better method to prevent paint bleed. The trick is to paint one coat of gel medium (I used gloss gel as it dries totally translucent) over the tape edges, let dry, then paint as usual. Both the FrogTape and the painter’s tape work well with this method (though the painter’s tape had some gel bleed that could add an unwanted ridge at the tape line.)
Have you conducted any artists material experiments that you would like to share? I would love to hear about them.
