Embossing Medium is a smooth acrylic plaster designed to create a raised plaster look with stencils on furniture or cabinets. It can also be used to create other textures such as lace, grasscloth and as a base for a hammered copper look. No priming is needed with this product. Apply it over wood or painted surfaces using our Behr Trowel, Bondo blade or brush. Embossing Medium dries to a flat finish and becomes very hard. It can be sanded and is easy to work with. Embossing medium can be painted, glazed and/or topcoated. Clean up is with warm soapy and water.
