"Had some very badly contaminated facing bricks after removal of rendering. I used 2 of these to completely remove all traces of old paint and render from some 500 bricks with ease. Bricks look like new and the second disc still has some life in it. Easy to use and control in order to only remove the contaminates. A really good buy."
"I bought this along with a backing pad to clean a wall built using reclaimed Cafferata bricks which was covered with a fair bit of mortar (it was my first time). Having read the previous reviews and the product description I hoped this disc would remove the majority of mess. Testing on spare bricks, the disc removed the detritus but also marked the face (the pressure used was light) - I would not recommend this product for cleaning the facing side of bricks."
