I own a home in the beaches area of the city which had delicate brick (100+ years old) which at some point had been painted white. I wanted to reveal the beautiful red brick underneath and DMA came through. There were some intricate columns, stone work and brick from which the paint was removed. Everything came out very nicely and i was surprised how much even the mortar was able to be cleaned off. My one complaint was that cleanup of the paint chips produced by the removal process could have been better as i had to do some sweeping of the street after. Nonetheless I had tried for hours to get even a tiny bit of paint off the brick using scrapers, brushes and chemicals with no luck - these guys did it in a flash and to a much higher standard than anyone could ever hope to do on their own.
