Flash Harry Thermoflex Primer is a solvent-based bitumen primer designed to improve adhesion and surface preparation before the application of torch-on waterproofing systems. Its excellent penetrative properties help create a dust-free, well-bonded surface for Thermoflex waterproofing membranes and other compatible bitumen coatings.
Ideal for roofing and structural waterproofing applications, Thermoflex Primer also assists with corrosion protection and adhesion enhancement on metal roofing surfaces prior to aluminium protective coatings.
