How to Use Concrete Molding and Stamping Rubber 75A Urethane
Concrete molds can be used for crafting interesting or technical shapes out of pourable concrete. The polyurethane concrete molds are best suited for portions of concrete, and should definitely be included among your stamped concrete supplies.
Polyurethane molds for concrete can be used for pourable concrete as well as hard rubber stamp molds. Be sure that when using this product, you use hard plastic or metal mold frames and stir sticks — paper, cardboard, or wood will come apart and contaminate your mold.
- Shake both Bottle A and Bottle B vigorously about 30 minutes before pouring
- Mix the two solutions in a clean container (in a 1:1 ratio) for 60 seconds
- Pour freshly-mixed urethane molding rubber into a second mixing container, mix for an additional 60 seconds
- Pour into your casting within 5 minutes of this subsequent mixing
- Let each layer cure before applying a new layer
- Remove from casting using a mold release
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 rubber urethane solution can be trusted to provide the quality tear resistance your project requires.
How can I ensure that the concrete does not stick to my molds?
Concrete can be a tricky substance to work with, so you’d be wise to think carefully about how to keep it from sticking to your molds. The molds are durable, and can be used for multiple castings, but in order to do so you’ll need to keep them clean.
Use motor oil or castor oil in your molds prior to pouring concrete to ensure that the dried concrete easily comes apart from the mold.
How easy is it to make my own concrete mold?
AeroMarine’s products are as simple to use as they are durable and efficient.
Our concrete mold comes separated into two bottles: Part A and Part B. Mix the two at a 1:1 ratio in a mixing bowl made of hard plastic or metal.
Once you’ve opened and poured the polyurethane, be sure that you close the lid tightly to avoid contamination or the polyurethane drying out.
