One Step™

One Step® is a convenient, economical liquid sealing agent and release agent in one. This non-flammable, low VOC formula is offered as a “one step” alternative to using a sealing agent followed by a release agent during the mold making process using Smooth-On urethane mold rubbers. One Step® will facilitate the release of cured urethane mold rubber from plaster, concrete, stone, brick, marble, limestone, wood, metal and other surfaces. Do not use on modeling clays.
