Wedi Board

[tay1974]

Is it possible that when I remove the tiles any damage to the Wedi boards could be skimmed over with using a cement based adhesive and then tanked using something like BAL WP1?

At the moment it sounds like I may have to replace all the Wedi boards with new ones.

How thick is the original Wedi? Is it set in a full bed?Or are they dot and dabbed? Are they Dübbled(Screwed to the wall,Wedi system).
Maybe It would be better to put a price it up making everything new!!?
Its also possible to renew with 1cm wedi using Rotband (haft Plaster, Knauf) or a Flexible Adhesive , full Bed,tape up,lay tiles next day.
It is possible to Skim the original wedi, but use a plastic mesh to reinforce it.If you use an adhesive with Trass cement in it,tanking would be over the top.Trass is water repelant!But tape the corners!
Hope this helps, materials here are a little different!

one thing I just thought about....beware if you are doing a demo and the Wedi was installed with the proprietary sealant/adhesive**. We did a steam shower about two years ago, and one day we had to remove a piece for some reason (don't remember why), and the Wedi glue that we used on the studs had a tenacious bond and it was a real PITA to deal with.:mad2:

**assuming it is the same stuff sold over here...some sort of polyurethane sealant/adhesive.

Hi 2Balls :smilewinkgrin::smilewinkgrin:

You're right, Paul didn't say studs behind the Wedi.....we are all so used to stud framing here that I didn't think of anything else.
