Montana Colors’s MTN PRO Chalk is a water-washable spray paint can, ideal for temporary marking or temporary art. Chalk has a texture similar to chalk. To erase it, nothing could be simpler since it is soluble in water. The less porous the surface, the faster the cleaning. Versatile, it is as effective for temporary signage of an event as a workshop with children. At the end, a simple sponge or basic water under pressure will take care not to leave any trace on the support.
