Kerdi Board and Bathroom Tiles

Kerdi board comes in the following thicknesses: 3/16", 3/8", 1/2", 3/4", 1-1/8", 1-1/2" and 2".

When preparing your bathroom walls for tiles, you can often be confronted with more layers than a wedding cake. There’s the mould-resistant drywall, concrete board, a waterproof membrane and thinset. Whew. Then the tiles go up.

The folks at Schluter have come up with a product that cuts down on the stuff that has to go up on your bathroom walls. It seems they’ve taken their Kerdi membrane (Layer 3, above) and turned it into a board. The Kerdi board can be attached to existing walls, or can be used to build new walls. The boards, which have an extruded polystyrene foam core with reinforced layers and fleece webbing, can be fastened to wood or metal studs with screws and washers. You can even construct partition walls themselves with this board. All it takes is a utility knife and the right bonding agent. Then you can put the tiles up on the board.

Have you worked with Kerdi board? Even if you haven’t, what are your thoughts on this new product?
