Platinum DM3 Pro-Mesh is a composite Damp Proofing Membrane comprising of HDPE membrane with a rot-proof HDPE mesh heat-welded during the manufacturing process to the surface of one side. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard. Platinum DM3 is 0.5mm thick and has a pattern of raised 3mm studs. The studs face the wall and create air channels that allow for vapour equalisation to take place between the membrane and the wall. Platinum DM3 is light, clean and easy to handle. It can be cut with a sharp knife, scissors or shears. The membrane is inert and is highly resistant to water, alkalies, saline solutions and organic acids. It is also resistant to bacteria, fungi and other small organisms.
