SEALMASTIC solvent-type dampproofing is an asbestos-free, fibered and non-fibered asphalt compound. Both the brush-on and trowel-applied versions are flexible and will span small holes and hairline cracks. All three grades withstand temperature changes and will not crack under normal expansion and contraction. The three types offered are SEALMASTIC SPRAY-MASTIC™, a non-fibered asphalt compound for use where spray application is desired; SEALMASTIC SEMI-MASTIC™, a brush or spray-on fibered asphalt compound designed to protect exterior below-grade masonry walls; and SEALMASTIC TROWEL-MASTIC™, a trowel-applied, heavy-bodied, fibered asphalt compound for exterior, below-grade masonry wall surface applications. It is recommended to protect porous or irregular surfaces.
