Seal Dit for use with porous materials 8oz. (227gr)

Seal-Dit™ – Food Grade Sealer - Seals wood, plaster, paper, cloth, sea shells and almost any porous surface, making these items suitable or the application of silicone mold making materials. If a porous material is not sealed, silicone will find its way into the microscopic holes in the surface, cure to a rubber and become mechanically locked to the surface. In other words, you are going to have to rip the object out of the mold ruining the mold and possibly the object being duplicated. 8oz. http://www.makeyourownmolds.com/how-to-use-seal-dit
