RFC Epoxy Damp Proof Membrane


SKU: N/A Category:


RFC Liquid Damp Proof Membrane (DPM) is a professional 2 component applied surface primer. It’s primarily designed for brushing onto concrete floors and fine concrete screeds. It has excellent adhesion to damp cementitious surfaces and once dried provides a dry barrier against moisture below. That means it’s perfect for damp proofing a cellar or basement room.

Fast Curing System

The fast curing time also means this liquid damp proofer can be quickly overlaid with vinyl, carpets, laminate flooring and other resin based products without the conventional “drying out” period being observed. A minimum 2-coat application is recommended for the best results. If covering with another material such as vinyl we recommend any adhesive being used is water based as epoxy based adhesives can weaken/attack the DPM over time.

While this epoxy based liquid DPM does offer some resistance against chemical spillage it’s primary function is to provide a damp proof barrier. For spaces such as factories, workshops and warehouses that want a complete resin system, we would then recommend painting over with 2 coats of RFC Epoxy Floor Coating for a complete protective resin floor installation. This also offers decorative properties great for car showrooms and similar environments.

Liquid DPM Applications

RFC liquid epoxy damp proof membrane is perfect for ensuring damp doesn’t work its way through to a decorative surface. In residential environments, it’s perfect for cellars, basements or garages that have been made into living accommodation or games rooms. Commercially this product is good for inspection pits, workshops, laundries, dairies, kitchens and food storage areas.

The resulting surface can be painted over with a resin-based coating or overlayed with carpet or vinyl coverings.
