Polyurethane molds for concrete can be used for pourable concrete as well as hard rubber stamp molds. When mixing this product, use only clean plastic containers and stir sticks — paper, cardboard, wax and/or wood will contaminate your mold.
Pro Tip: Use AeroMarine Products’ concrete molding and stamping urethane rubber between 65° and 75°F in a humidity-controlled environment.
We’re proud to offer industrial-grade materials that provide durability and strength. Like our RTV mold-making kits and silicone potting compounds, this urethane rubber can provide the tear resistance your project requires.
You can use the mold release paste that we sell with the concrete molding and stamping rubber. Please clean your molds thoroughly and dry them completely before your next use.
Our concrete molding rubber comes in two bottles: Part A and Part B. Mix the two parts at a 1:1 ratio in a clean plastic container.
Once you’ve opened and poured the polyurethane, be sure that you close the lid tightly to avoid moisture contamination or the polyurethane drying out.
