New Surface is one of the coolest products Plaster Paint has! Its job is to help your paint adhere to whatever surface you choose. New Surface can be applied to any piece of furniture, glass, metal, or wood, tile, slick surfaces, gloss finishes, varathane finishes, high gloss paints...the list goes on. All that is needed is one light coat before you paint and you are ready to start painting. And yes, this also means you DO NOT need to sand first.
