I am building a study with a stained wood ceiling. I am installing
1/4" plywood between beams. The ply is approximately 4'X4'. I have screwed 1/2 ply to the ceiling primarily to serve as a backer board for nailing the crown molding and next I need to glue the 1/4" ply to the 1/2" ply. My question is how do I hold the 1/4" ply in place while the glue dries so that I get a good even lamination of the two plys? I plan to use construction adhesive. Is there a better glue? Perhaps contact cement would be a good option.Thanks in advance for any help.
