I am so impressed with how you product worked on my brickwork. The bricks had an insoluble milky salt or lime residue on them. I was able to dye these back to the original colour using sample pots of your 'Mocha', Warm Orange' and 'Classic Brick Red'. Thank you for such a great product!
THANK YOU! I bought a fixer upper that had a terrible case of efflorescence on the chimney. I was a bit wary that dye would be able to cover how extensive the efflorescence was, but everything else I had tried (muriatic acid) didn't work. Nine months later, I still love the results!
