3M™ Booth Coating is a water-based solution for protecting paint booth walls from paint overspray. Simply apply 1 to 2 medium wet coats with any 2.0 spray nozzle, such as the Accuspray™ 2.0 disposable spray nozzle. 3M™ Booth Coating dries to a clear film across fittings, walls and windows. The non-tacky formula won't discolor from dust or dirt, and removes cleanly with water.
