High-Performance Moisture Cure Epoxy Membrane
Duram Primeseal MC (‘Moisture Cure’) is a high-performance, two-part, water-based epoxy waterproof membrane. Engineered for versatility, this hydrostatic pressure-resistant coating is suitable for porous and semi-porous surfaces, including green (newly laid) hardened concrete and damp substrates.
Primeseal MC cures to form a robust water vapour pressure barrier, capable of withstanding up to a 25-metre head of water pressure. Its low VOC formula meets ‘Green Star’ environmental criteria, making it safe for various construction environments.
Versatile Applications & Priming
Primeseal MC is more than just a membrane; it serves as an exceptional primer for waterproofing membranes, paints, and industrial coatings. It acts as a critical bridging layer between normally incompatible coatings.
Primary Uses:
- Damp Concrete: Seals and waterproofs green or damp hardened concrete.
- Negative Pressure: Waterproofs inside surfaces (basements, lift wells, cellars).
- Positive Pressure: Protects outside surfaces and water-retaining structures.
- Vapour Barrier: Prevents membrane bubbling caused by substrate vapour emissions.
- Substrate Sealer: Ideal for timber floors prior to membrane application or concrete floors before timber laying.
Suitable Surfaces:
- Concrete, cement render, brick, masonry, and block work.
- Hebel, timber, FC/CFC sheeting, and plasterboard.
- Damp surfaces (must be free from standing or running water).
