Stand Off Stone, Tile & MasonryProtector can also be used.Lime run (carbonate staining)Description – Hard whiteor gray surface crustconcentrated along amortar joint or runningdown from a hole orfine separation crackbetween brick andmortar joints. Does notdisappear when wet.Cause – Water depositedor collected in the wall Lime run on brickduring construction oras a result of inadequate waterproofing dissolves water-solublecalcium compounds. Over a long period of time, the watermigrates through openings in the wall surface. As the waterevaporates, the dissolved calcium reacts with the atmosphereand crystallizes to produce a hard calcium carbonate crust onthe masonry surface.Removal – Carefully remove as much of the crust as possibleusing wooden scrapers. Then use Sure Klean Custom MasonryCleaner or Heavy Duty Concrete Cleaner following labelinstructions. Repeated controlled applications and agitationmay be required.Prevention – Protect wall cavities from rainwater duringconstruction. Clean with the appropriate Sure Klean newconstruction cleaner.
