Delta Roof Guard QC - B4 (T-roof) Liquid Roofing Membrane

A rapid curing one-component, liquid waterproofing membrane which is laid in a two-layer system, enabling Delta Roof Guard Glass Fibre Reinforcement to be embedded in the base layer. Offering a faster curing time, as the two-layer system will allow for inspection of the base layer prior to application of the top coat.

Features and benefits:

• A one component liquid semi-thixotropic waterproofing composition, after polymerization gives an elastomeric, cold-applied polyurethane membrane.
• The membrane cures in a continuous and elastic form, as a totally adhered layer.
• This waterproofing layer guarantees total water tightness and withstands building movements.
• When the base coat has cured, inspect base coat for pin holes. If any repairs are required they must be fixed at this stage.
• BS 8102:2009 Type C drained protection.
• Broof (t4) fire classification.
• BBA approved.
• Green roof approved.
• Quick installation times offering cost savings.
• Avoiding inherent risks associated with hot works.
• Seamless applications no joints or fixings.
• Exceptionally fast curing.
• Compatible with a wide range of substrates.
• Easy to maintain.
• Minimal on-site disruption.
