When water penetrates the walls of a structure it can cause a wide range of undesirable effects. Slowing the penetration of water into walls and reducing the transmission of water vapor is crucial for the long-term health of buildings. Dampproofing membranes coat walls and foundations to reduce the penetration and transmission of water. Mar-flex created DampFUSION to provide a top-of-the-line dampproofing membrane for projects where waterproofing membranes are unnecessary, uneconomical or simply impossible to apply.

Advantages:
• Water-based; no odor
• Stops water vapor transmission
• Can be applied to damp walls
• Seamless, monolithic coating
• Gray in color; blends in with concrete
• Can be applied to top of foundation walls
• Surface cures within 24-48 hours

Mar-flex DampFUSION is an excellent water-based acrylic dampproofing membrane approved
for masonry, block, pre-cast and poured concrete wall foundations. It will stop water vapor
and protect against leaks.

Mar-flex DampFUSION is a spray-on membrane, so it dries as a seamless, monolithic coating.
It can be applied to pre-existing damp walls and the top of the foundation wall. It has no odor
and will dry to a gray color to blend with the color of concrete. DampFUSION is compatible
with Mar-flex drainage and insulation boards.

Dampproofing is often confused with waterproofing. Dampproofing simply slows down water
penetration but does not completely waterproof a foundation. It is generally very effective in
stopping water vapor transmission.
