We used styrene tiles for the popcorn ceiling in our bathrooms and spare bedrooms. It was very easy to work with, but used A LOT of caulk for the seams. We wanted to try the pvc tiles for our kitchen because it would be more durable. Someone asked if it could be used as a glue up, but wayfair answered no. After researching, other brands recommended their pvc tiles could be glued up with construction adhesive. The Art3D brand was less $ per square foot, so we tried it anyway. It worked! BUT, do not use Power Grab. It worked well for styrene but couldn't handle the weight of the pvc. We used gorilla glue ultra construction adhesive. It was more money, but used MUCH LESS glue than the Loctite brand. We overlapped the sides so we didn't have to caulk the seams. Also, use good cutters like tin snips. Blades do not work as well. Our ceiling is beautiful and we plan to buy more for the rest of the house. It will be more durable than styrene and easier to clean. Styrene attracts static.
