Have a job on where some wee ned has poured some kind of red paint on a driveway of light grey concrete slabs. Tried paintstripper (2 types) for 20mins then jet wash off, but still the staining remains. Anyone got any ideas?
first u need to determin if the paint is water or oil based 111 If water it is unlikely whatever u do will get it off as it would of soaked in to the slab!!!!If oil try a chemical brick cleaner that might do it!!!!Good luck
Is there paint left on the slabs you are trying to remove,or are they stained after removal of the paint ? At work,we carry paint around in 25,000 litre tanks - water-based paint normally cleaned with caustic soda,resin-based (U.N. No.1866) removed with butyl acetate. If the paint has been removed,and you are just left with staining - sorry,but I don't think there is an easy answer
