How long do I have to wait before I can install tile on the Schluter®-KERDI membrane?

Once the KERDI membrane, including seams, corners and protrusions have been completely bonded and, therefore, waterproofed, the assembly is ready to be tiled. No wait time is required.

A water test may be performed before setting tile to verify a successful waterproofing installation. This evaluation may be required by building code officials and is considered best practice. Wait 24 hours after the membrane installation is complete to allow for the final set of the mortar and to ensure waterproof performance of the assembly at seams and connections before water testing.
