Surface Preparation & Primers
Proper surface preparation is critical to the performance and longevity of any waterproofing system. HPMA primers are formulated to enhance membrane adhesion, stabilise substrates, and improve compatibility across a range of surfaces.
Designed for use on concrete, masonry, screeds, and other common construction substrates, HPMA primers support reliable membrane application for internal and external waterproofing projects across Sydney and Australia.
Single-pack moisture-curing polyurethane primer to promote adhesion on porous substrates.
Two-part epoxy moisture barrier suitable for green or damp concrete.
Solvent-free primer for dense, metallic, or glazed surfaces.
