Moisture-Curing Pure PU Coating
TM PurePU
One roller-applied membrane — no mesh, no overlaps.

Overview
TM PurePU is a pure PU system rather than a PU dispersion — once it catalyses on contact with atmospheric moisture, it transforms into a single continuous elastic membrane, which is what removes the need for reinforcing mesh or overlapped sheet joints entirely.
At roughly 450% elasticity, it's the most elastic membrane in the range, built for decks and roofs that see real structural movement and where a stiffer coating would eventually crack at the stress points.
It's applied by roller and left to cure with atmospheric moisture rather than a mixed hardener, which keeps the application straightforward on site — roll it on, let it catalyse, and the membrane is the finished waterproofing layer.
Key features
- ~450% elasticity — the most elastic membrane in the range
- Moisture-curing — catalyses with atmospheric moisture, no separate hardener
- No mesh or overlapping system needed
- Simple roller application
- Forms one continuous elastic membrane rather than a jointed system
