Silcone in wetroom ??

**ftm** · 22-07-2011

Hello

Finishing off a wetroom, the walls are tiled, floor about to go down with 25mm mosaics on Gmat over Bal WP1, the floor will be grouted with Kerapoxy, do I need to run a bead of silicone between wall and floor, or will the epoxy grout stop any leaks ?

Cheers

Yes use silicone which will cope with any movement between the substrates.

Make sure that the joint to be siliconed is clear from any grout. If you silicone over grout, the grout will crack and take the silicone with it, leaving a gap for water to get through and do a lot of damage.
