- Preparation & Application
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 Anti Slip Liquid Roof Membrane is moisture activated, therefore once opened, all material must be used immediately. The tin cannot be re-sealed.
Application 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 Anti Slip 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.
