Gostatue molds is a manufacturer of over 5500 quality plaster, concrete, cement, soap, candy (not food grade), wax and resin molds. All of our molds are made from high strength plastic or commercial grade latex. We use over a dozen different plastics to make the mold that is best suited to the the design that is being cast. All orders come with instructions for easy casting. There are great premixed cements on the market nowadays which can allow anyone to cast like a pro. Rapid set cement all, sand topping mixes and underlayment mixes are all great for casting the thinner molds such as tiles and plaques. Quickcrete concrete mix is a great mix for the thicker castings such as benches and stepping stones. Release is a must when casting resin or concrete into the plastic molds. It is a good idea to coat them with Armor All. That will allow the resin or concrete to come out quite easily. Spray Pam will also work for concrete casting in the plastic molds but not for resin.
