Ronjon Damp Proof Membrane
RONJON DAMP SURFACE PRIMER
Ronjon Damp Proof Membrane and Damp Surface Primer are solvent free two pack epoxy coatings which will cure on wet or damp surfaces. If used alone they can provide a dustproof easily cleaned surface with good resistance to chemical spillage. If used as primers they should be overcoated while they are still tacky to provide maximum adhesion. Damp Proof Membrane is a more highly formulated product designed to provide a pinhole-free moisture barrier and is normally applied as a 200 micron coating.
Both Membrane and Primer are eminently suitable for application to recently laid or refurbished concrete floors allowing them to be quickly brought into use or to be immediately overlaid by a final floor finish. They are also suitable for use under cement based self-leveling finishes which are often affected by moisture ingress.

As with all systems the degree of preparation will determine the effectiveness of the product. Surfaces to be treated can be wet, damp or dry but must be free from laitance, loose dust, dirt, debris or contamination. New concrete should be cured but these products can be used on damp or wet surfaces. Pools of water should be removed if possible.
Add the full contents of Base and Hardener containers together and mix thoroughly with a slow speed drill and suitable paddle. Once mixed the coating will remain workable for 1hr 20 mins.
Apply Ronjon Damp Surface Primer by brush or roller working in to emulsify any surface water if necessary. Application temperature should be above 5 0C
Application of the Ronjon Damp Proof Membrane is similar but a thickness of at least 200 microns should be applied to floors or walls. Equipment should be cleaned immediately after use with Ronjon Cleaning Solvent.
