Anyone ever used any Wedi Corp products? Daltile just started distributing this stuff and it seems quite interesting. I'm thinking of using the wallboard for my bathroom shower remodel this fall. The wallboard has a moisture proof core and a waterproof membrane already on the face on it. You just tape or caulk the seams and screw heads with the approved sealants after screwing it to the wall and no need for further waterproofing before laying tile. It seems like one of those too good to be true things. Any input is appreciated.
