Well, there i was louging and watching a bit of TV ...There was a show on called "Completely Hammered" (Or something like that). One of the people on the show had tiles falling off the wall in her shower, and wet behind. So in comes the "Handyman". He strips off a few tiles, cuts out the old sheetrock, and here's where it got plain ugly...He installs the green drywall (he says its water resistant), tapes the seams with mastic adhesive then starts to reinstall the tiles over the new greenboard. Off course he also puts in a soap dish using mastic as well...Talk about a great job... Too bad it'll be damaged again so soon! I guess that's how the Hammered guys keep working...continually fixing old botched jobs. If I hadn't read all the information here, I would have thought it was the right thing to do. Now I know better and I just shrug my shoulders!
Cheers!

I'll have to look out for that one. Sounds fun.
