Sealer PS105 Silane Water Repellent WB-40 Penetrating Sealer (5 gal.)

Malmer PS105 (176035) Description

PS105 is a water based penetrating, 40% chemically reactive triethoxyoctylsilane which repels water and moisture from concrete and masonry offering invisible protection and a low VOC. At only 5 angstroms, its small particle size makes it ideal for very dense substrates made of high performance concrete such as cast in place, poured in place, and reinforced surfaces. It penetrates deeply and chemically reacts with concrete and masonry components for long lasting protection. PS105 seals pores and capillaries of substrates preventing liquid and moisture absorption while allowing excellent vapor transmission. It combats efflorescence and dusting, freeze/thaw damage, deicing chemicals, acid rain deterioration, salt intrusion, UV damage, scaling and spalling, dirt buildup, staining, mold and mildew, alkali attack, and corrosion of reinforcing steel. It is designed to provide a high level of surface beading with penetration to protect against wind driven rains. It is also UV resistant and nonyellowing. PS105 has a milky white appearance. Upon proper application, it generally does not alter the texture of the substrate but may darken the substrate especially with over application.
