I've had problems in the past with gluing
commercial flooring tiles to
OSB subfloor using the standard adhesive that looks and feels like contact cement. I followed the instructions and let the glue cure for about 30 min before setting the tiles but some tiles eventually came unglued. May have been partly because the OSB surface is rough so the contact surface wasn't evenly distributed (just a guess).
In the project I'm doing now, I actually set
1/2" plywood (smoother than OSB) over the OSB and I plan to put tiles on top. My question is, is there something I can
prime the plywood before applying the adhesive so that I can achieve a better and more durable grip than I did in the previous application.
