Gruber's mold sealer for cultured marble and other engineered composite fiberglass open molds. GruberCare MR Sealer is designed as a mold sealer for glass reinforced polyester, vinyl ester, epoxy or metal molds. For use in combination with the MR GP and MR HI-TEC products. It should be used to prevent styrene emission or migration from new molds and eliminate surface porosity of metallic molds. The resin both seals micro porosity and fills minor scratches on the mold surface. The result is a smooth, high gloss surface primed for GruberCare top-coat application. GruberCare MR Sealer is especially recommended for use on new molds and repaired areas on older molds.
