Casting Concrete Will Never Be The Same! Formulated especially for casting concrete, VytaFlex™ Mold Rubbers are next generation urethanes that feature Smooth-On's V-Polymer™ Technology.

"We've been cycling VytaFlex™ molds for over three years now and they show no signs of giving out at all." – Dale Groff, Lancaster Stone, Lancaster, PA
Stone models are sealed with SuperSeal™ sealing agent and Universal® Mold Release then applied to all surfaces that will come in contact with the mold rubber. Measure and mix VytaFlex™ 40 mold rubber and pour slowly over model. Demold original model.
Pigment the mold cavity. Then cast concrete into the mold. Let the concrete set.
After the concrete has cured, the mold is stripped off the casting, cleaned & ready for casting again. VytaFlex® urethane rubber molds can yield hundreds of castings.
