Acrypol Tech Seal PU is a seamless, liquid waterproofing membrane made up of single component PU. The polyurethane doesn’t need to be mixed with anything else, so this simple 2-coat system applies very easily. Applied by roller or brush to asphalt, bituminous felt, concrete, metal and single ply surfaces, this Acrypol liquid membrane is high performance.

Acrypol Tech Seal PU is rain proof in just 2 hours and will be fully cured in 4 hours. There’s a 20-year guarantee when this product is installed on flat roof, balconies, gutters and green roofs but it’s also applicable to podium decks, roofs, terraces and more. Acrypol Tech Seal PU is high performance and when it cures it presents a tough, durable and strong waterproof membrane.

This waterproofing membrane is for use on flat roof overlays and traditional roof build ups, but no primer is required for bitumen or asphalt roofs. For single ply PVC and metal roofs Acrypol TS PU Primer is required, for dry concrete Acrypol Porosity Sealer Flex primer is required, and for damp surfaces like timber or concrete then Acrypol TS Humidity Primer is required.
