Blowerproof Liquid Airtightness System

Ecomerchant Blowerproof Liquid Applied Airtight MembranesBlowerproof products are all derived from the same proven and tested formula offering a  fibre reinforced brush applied version and a liquid version for either roller or spray application with no fibres.

The brush version is used to seal penetrations, connections, window jambs and difficult to treat applications and as a preparatory treatment before spray applications for larger areas. the spray/roller version is perfect for larger areas direct to blockwork, masonry, concrete or even insulation.

Blowerproof is a unique and simple way to provide a permanent secure and flexible seal between a wide range of substrates with no primers or adhesives required. Available in a range of pack sizes this versatile product is a must for any building project where reducing air leakage is desired.

Simple, clean and easy to use keeping Blowerproof on-site means you never miss an opportunity to seal up gaps just when you need to.

Blowerproof technology with a lower Sd-value of 0.8m and an upper Sd-value of 21.7m provides outstanding humidity protection compared to other VCLs and helps to accelerate the drying out process of wet construction materials.

Blowerproof is BBA & Passive Component certified.

  8. Blowerproof Primer43 (5Kg)

    Blowerproof Primer43 (5Kg)

    £49.99

    PRIMER 43 is a water-based primer, applied on porous and less cohesive substrates, prior to the application of waterborne dispersion coatings. The use of this primer will consolidate the substrate and improve the adhesion of coatings on difficult substrates.

    Use with Blowerproof Liquid Membranes: although Blowerproof membranes do not normally require a primer where Blowerproof is applied directly to plasterboard or gypsum plaster the manufacturer recommends the use of Primer 43.


    Typical uses:

    • on older dusty substrates to consolidate
    • on water sensitive substrates such as gypsum board and gypsum plaster.

    Coverage: typically 100g/m2 dependent on substrate porosity

    One 5kg can will cover up to 50 square metres.

    Price is per can
