Waterproofing and Deck Coatings in Simi Valley

Ultraviolet exposure is the defining condition in Simi Valley. Summers are long, clear and hot, and a coating that is never rained on for six months is still being destroyed the entire time by sunlight, which breaks down the binder in anything not formulated for it. We routinely find deck systems here that look intact from a distance and are chalking and crazing when you get on your knees on them. Concrete surfaces show it too, in the form of surface scaling that has to be repaired before anything new can bond. The other local factor is the planter box, which is on almost every house in the older tracts: a masonry box holding wet soil against an exterior wall, usually with no membrane and no way for the water in the soil to leave except through the wall behind it.
