Buy separate pieces of SlabMat for each color clay to prevent contamination.. You may wipe the surface with a damp sponge, but do not saturate it with water. Allow the SlabMat to dry completely before use.
It is best to remove the slab soon after rolling because prolonged wetness may cause the SlabMat surface to become wavy. Store SlabMats flat. To extend the life of SlabMat, avoid excessive heat and direct sunlight.
