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.

Question:
last year I coated my felt flat roof with Acrypol Tech Seal PU Liquid Waterproof Membrane in Light Grey - but due to the heat this year ( now in summer 30 degrees +) i see erupted bumps on the roof ( the felt under this coating is risen and under the felt, I think the black tar paint has melted. What can I do do repair this - do I buy another tin of Acrypol Tech Seal PU Liquid Waterproof Membrane in Light Grey ? regards Mr Ahmad
Answer:
If the felt was damaged before painting you may have to pull it off and start again - you could also try repainting but add the acrypol scrim to reinforce the application
Question:
Can it be applied over bitumen?
Answer:
Yes as long as it is still sound
