Enviro-Shield 40% WB - Premium Water Based Water Repellent


Water that seeps into brick, mortar and stone can cause all sorts of issues from efflorescence and mineral staining to cracking and spalling due to freezing temperatures.  Not all water repellents are the same.  Enviro-Shield 40% WB is the water based version of our high solids Enviro-Shield 40%.   It is a high performance, clear, penetrating water repellent sealer.  It is designed to provide long term protection for brick, blocks, Jersey barriers, vertical or horizontal concrete and natural stones and other porous surfaces.

Further Proection:

Sealing the masonry surface will prevent water and moisture from penetrating the surface.  Water will also migrate in through cracks in joints or mortar, leaking roofs or dozen other ways.  Weep holes are an important part of keeping a building dry by allowing trapped moisture to escape.  Our Drain Only Weep Tubes efficiently wick away moisture while at the same time preventing insects, dirt and debris from entering the weep holes.
