Concrete casting pros from around the world know Smooth-On liquid rubber products as the industry standard for making rubber molds that have the abrasion resistance and tear strength needed to keep production moving.
Both urethane and silicone mold rubbers can be used to make architectural elements, concrete stone veneer, large scale formliners, concrete countertops, GFRC panels, concrete stamps and more. The high abrasion resistance and toughness of urethane rubbers such as Vytaflex ® mold rubbers allow for a very long production life.
Concrete forms are often categorized by where and how they are used. The best form for a particular project is often a function of the pour size, the amount of concrete the form needs to retain, and the pressure or weight that will be pushing against the form.
