  • The liquid roller/spray is applied directly to the surface with no primer. This makes it perfect for quick and simple application with minimal wastage. How it works is the blue colour will change to black once it dries for easier identification throughout the process. When dealing with penetrations and connections, you can seal these before roller/spray application. Do so by 'cutting in' with a Blowerproof Liquid Brush. The more significant gaps and holes can be plugged using the Blowerproof Non-Shrink Gap Filling Mortar to ensure a permanent and flexible airtight layer.
