You need a certain amount of acid, just a small amount of highly purified, high-grade acid that is harnessed by surfactants and inhibitors and wetting agents. And, because the dyes used on some veneers are water based, they don’t adhere well, even to the surface. So, most contractors turn to acid washes, which are not necessarily the best approach today. This technique prevents streaking on the surface. Depending on the contaminants present, agitate with a nylon brush, if necessary. Available in one gallon and five gallon pails. This product provides an average spread rate of about 200-250 square feet per gallon. This product is a very strong acid that will clean dried cement products off stones, bricks, and other masonry surfaces. Water is used to wet the surface before and after cleaning. Place the containment sock around the bricks being cleaned on top of the tarp to further contain the mess. Dip a second brush into the masonry cleaner mixture, then gently apply the brush to the brick. Repeat this process until the brick is clean.
