Bathroom & Wet Room Waterproofing

A leaking bathroom damages the slab below it and the finishes above it. This system seals the wet zone before tiling so water stays where it belongs, applied in three stages with a verified datasheet at every step.

How the system works

The sequence starts with a sound, clean substrate and an SBR bonding slurry. Two coats of cementitious waterproofing slurry follow, with corners, drains and pipe penetrations reinforced before the field coats. Tiling proceeds over the cured membrane with a polymer-modified adhesive and matched grout, so the finish never becomes the waterproofing layer.

Common questions

Asked on real sites.

Can I apply this over existing tiles?

Only over a sound, well-bonded surface. Loose tiles, paint and laitance come off first. When in doubt, remove back to concrete and rebuild the sequence from the bonding coat.

How long before I can tile over the membrane?

Follow the waiting time on the product TDS between coats and before tiling. Rushing this step is the most common cause of debonding.

Do I need to waterproof the walls too?

Yes in shower zones, typically to full spray height. Floors alone leave the wall-floor junction exposed, and that junction is where most bathrooms fail.
