Description
Internal corners are a classic weak point in wetroom tanking, so ButylXpress Pro takes the guesswork out with a pre-formed detail moulded for 90-degree inside angles. Measuring 140mm x 140mm, it is made from a self-adhesive butyl rubber sealing layer that gives a neat, dependable seal exactly where two walls and a floor come together.
Key features
- 140mm x 140mm pre-formed internal corner
- Shaped for 90-degree wall-to-wall and wall-to-floor angles
- Self-adhesive butyl for an instant, permanent seal
- No priming, no slurry, no drying time
- German-made part of a certified bonded system
Fitting is quick: remove the liner, seat the corner into the angle and press it down so the butyl forms a watertight bond. Fit the corners before the main membrane goes on, then cover the walls and floors with the fleece-faced ButylXpress Pro membrane, which laps over the detailing to give the surface you tile onto. For the opposite geometry on upstands and kerbs, reach for the matching ButylXpress Pro external corner.
Full System Guarantee. ButylXpress Pro is a complete, self-adhesive waterproofing system in its own right. Fitting the ButylXpress Pro membrane together with its matching self-adhesive corners, collars and tapes creates one certified bonded barrier — and installing the full, matched system is what qualifies your wetroom for the Substrat Full System Guarantee.
