Reinforced waterproof protection for flat roofs
Watco Liquid Roof Membrane is a roller applied coating system designed to protect flat and pitched roofs. Watco Liquid Roof Membrane can be easily applied around existing pipe work and protrusions. With an inert fibre reinforcement it protects around these areas where the risk of water leakage is high. Two coats will cure to give a tough, 1-1.5mm thick sealing membrane. Its high elasticity allows the roof to move without the membrane splitting or cracking.

Inspect entire surface to assess soundness of existing substrates or coatings. Where necessary prepare test areas. Repairs to cracks, holes, blisters etc, should be carried out before application of the coating. Ensure roof surface is clean, dry and free from all loose debris and roof contaminants. All fungal growth, moss etc. should be treated with a suitable fungicidal cleaner. General dirt and contamination can be removed with Watco Bio D, a biodegradable solvent free degreaser.
Please note: Watco Liquid Roof Membrane is moisture activated, therefore once opened, all material must be used immediately. The tin cannot be re-sealed.
If appearance is critical we recommend the application of a small trial area first.
Do not apply if rain is forecast within 12 hours. Stir contents thoroughly (do not thin). Apply Watco Liquid Roof Membrane by brush or short/medium pile type roller. Work material well into substrate. Apply generous amounts to areas at a higher risk of water ingress i.e. joints and protrusions with a brush prior to the application of the main coating. Two coats are recommended. The second coat should be applied after a minimum of 8 hours and a maximum of 7 days. An anti slip finish can be achieved by sprinkling the coarse white grit over the second coat while it is still wet.
