What is GacoFlex A4271 Bleed Trap used for?

GacoFlex A4271 is a base coat for suitable felt, asphalt and bituminous roofs before applying GacoFlex S42 Silicone Roof Coating. It traps oils released by bitumen, helping to prevent them migrating through and staining the topcoat.

Which roof surfaces can it be applied to?

It is suitable for built-up felt roofing, modified bitumen membranes, including torch-on felt, and smooth or granulated asphaltic membranes. It is not intended for gravel-surfaced roofs. Always carry out an adhesion test before application.

How much does one pail cover?

An 18.9 litre pail covers approximately 46m². Actual coverage depends on the surface texture, porosity and condition. Allow additional material for upstands and other roof details.

What temperature is needed for application?

The minimum application temperature is 10°C and rising. Follow the current technical data sheet for suitable weather conditions and drying requirements before applying the silicone topcoat.

Why is GacoFlex A4271 red?

Its red colour makes the applied base coat easy to see, helping you identify missed areas and check coverage before applying the topcoat.
