I bought a PVC drop ceiling from Art3D and was 100% disappointed. I chose PVC material because of the advantages I read about and the photos that show the product, especially after it was installed. But it's not exactly what is shown in the photos, as the 24x48 drop ceiling sheets are not 100% flat, all the ends have a gap, which will certainly warp over time. After the ceiling is finished, all I have to do is not look at the ceiling, or do you happen to have any solution you can give me?
