Since most dampproofing coatings are covered up by backfill or studwalls, it doesn’t matter what they look like. Sometimes, though, the foundation walls must remain visible, and in those cases you might want to try Sure-Coat. Part of the ProSpec line from Bonsal American, this portland cement–based coating is suitable for interior or exterior surfaces. It’s applied by brush, spray, or trowel and cures to form a durable fine-sand finish that can serve as a decorative coating, says the maker. Sure-Coat comes in gray and white, but it’s also paintable. A 50-pound bag costs about $28. Bonsal American, 800/738-1621, prospec.com
