densguard behind plastic tub surround

Bigguy0

I've installed densguard in my tub/shower and Im wondering about how to waterproof the seams and screw holes. Everywhere I've read (this site,other sites, the densguard website) only talk about using densguard when tiling. I'm installing a plastic tub surround. Do I still need to use fiberglass tape and thinset even when I am not tiling. I called densguard manufactures a couple of times and they have given me different answers to how to fill the seams. One person said that caulk will be fine if Im using a tub surround, another person said that I would have to speak to the tub surround company. Any suggestions? I've read some posts that say that I should use Redguard even with densguard but this was related to tiling. I think it would be overkill to redguard, since having a waterbarrier is what makes densguard different.

If you are installing a basic tub surround, I wouldn't worry about waterproofing the seams and screw heads. If tghe surround is installed properly, there isn't much of a chance for water to get behind it. Make sure you have a smooth substrate, use the proper adhesive for the tub surround, and caulk your joints.
