Always Color-Match a Repair Mortar to a Clean Substrate [Video]

Whether you’re color-matching on-site or sending us a sample for our lab custom color match, always clean the masonry you intend to use for your color match.

Check out this detailed video from Craig Schnellbacher, one of our Senior Technical Specialists in New York, who explains why you need to clean the match-to masonry and shows techniques for best cleaning the masonry surface.

Note that cleaning the entire surface is not required — you can simply clean the match-to section for the color match if you like.
