I need to make a series of completely flat sanding blocks and I’ve chosen to use 1/4″ acrylic sheet for my backing. Previously when I Titebond 3 glued sandpaper to sheets of 1/8″ acrylic they were all curled after the glue cured. So I’ve switched up to 1/4″ acrylic and I’m searching for an appropriate glue that doesn’t shrink. I would use rubber cement but the way that application works, apply to both sides, let dry and combine, would make for unwanted little lumps. I’ll be using a brayer to make everything as even as possible after the paper is laid down on the glue surface.
Any suggestions for a better glue?
Good question. The two things I have been looking for over the years are a good glue with the qualities you are talking about and a great tape that doesn’t leave glue behind and peels up easily but is strong enough where the corners don’t curl up.
