Blowerproof Liquid | Liquid Membrane and Mortar

Blowerproof specialise in airtight liquid membranes that are capable of supporting insulation systems. Their years of experience coupled with fantastic products ensures you can get the job done.

Liquid membrane

Blowerproof liquid membranes create uninterrupted air and vapour-tight seals around penetrations and connections, joints, gaps and cracks. The membranes can be applied with a brush or roller/spray and can be applied directly onto a surface without the need for a primer. They work well as a sealant for blockwork, masonry and concrete. The membrane liquid is BBA certified and is simple to apply. 


Blowerpoof’s gap filling mortar compliments the liquid membrane for gaps and cracks more than 5mm wide. It dries very quickly, leaving a repaired surface for Blowerproof liquid membrane to be brushed on top.
