A watertight low-profile sheet membrane for protection against dampness in walls without the need to drill and install plugs. The membrane is a 1.5 mm thick flexible polypropylene sheet with a fleeced surface on both sides. The two fleeces ensure good adhesion to the wall by means of Drybase Flex Adhesive, as well as the direct application of plaster to the face.
Drybase Flex Adhesive
Drybase Flex Adhesive is a polymer modified cement-based product used to fix Drybase Flex Membrane to walls. It is supplied in powder form ready to be mixed with water, and applied using a suitable trowel.

Apply Drybase Flex Membrane on top of the Drybase Flex Adhesive, leaving a 25 mm gap between the bottom of the membrane and the floor.
Apply Drybase Flex Adhesive up to the wall joint and 100 mm onto the abutting wall. Apply Drybase Flex Membrane up to the wall joint.
When plastering around a window, Drybase Flex Adhesive and Drybase Flex Membrane should both be applied up to and around the window frame and window sill.
Apply both the adhesive and membrane up to the door.
