RA-7315 is a fast drying barrier film for use with all types of resins in porous and non-porous molds. This barrier film prevents contact with the mold. RA-7315 may be brushed or sprayed onto the mold surface. Follow with a topcoat of paste wax or spray release. Unlike P.V.A., RA-7315 is not water soluble once dried, which is ideal for plaster molds where moisture is a problem. For porous molds, several coasts may be necessary. Apply until glossy. May be thinned with acetone.
