ar-flex Dampproofing Solvent Based is a heavy-bodied cutback asphalt protective coating used when lower temperature application dampproofing is required. It forms a smooth, tough, almost rubber-like film when dry. Mar-flex Dampproofing has moderately good resistance to temperature changes, is flexible at low temperatures, has excellent weatherability and resists
water penetration. The durable film bonds to most clean, dry and firm surfaces. All surfaces to be coated must be clean, dry, sound; free from oil, grease, rust, scale, loose paint and dirt. Mar-flex Dampproofing & Foundation Coating is compatible with Mar-flex Drainage and Insulation Boards.
Mar-flex Dampproofing is recommended for dampproofing belowgrade, vertical basement walls of poured concrete or unit masonry construction. It serves as a vapor barrier on the exterior face of the interior walls of above-grade exterior masonry cavity walls. It also excels as a utility coating on posts, pilings and other metal surfaces set into the ground.
