Latex Mold Making Rubber

I believe that this is the best mold making latex on the market. It goes on thicker than any other liquid latex, meaning that you can use fewer coats and make a mold much more quickly. This latex mold making rubber is extremely tough, very flexible, and is resistant to tearing. It is brushed directly onto the pattern, allowed to dry, and then reapplied. This process is continued until the latex mold has reached the desired thickness. When dried, this product resembles a rubber band. It can be removed from the original by rolling it up like a sock.

Latex is best suited for making molds for casting cement, concrete, plaster, hydrocal, or hydrostone. It can be used for limited runs of resin castings, but the yield is low.

Tips: Latex "air dries"- sort of like paint, but much thicker. To speed up the drying process you can use a heat gun to blow warn dry air over the freshly applied latex. Gauze makes a good reinforcement for a latex mold.  After brushing on at least 4 coats of latex add some gauze to reinforce the mold. Since it is so flexible, you may want to put a 'Mother Mold' around it so that the latex doesn't lose its shape when you are casting something into it. Alternately you can put the mold into a bed of sand so that the mold does not distort when being filled. When storing your latex mold leave a casting in it to help the mold to preserve its shape.

To make your latex thicker and to reduce the cost of making a mold, consider adding our black reclaimed rubber powder! If you must thin latex, distilled water is preferrred, although tap water seems to work OK. Thinning latex is not recommended because it slows the process and increases shrinkage.
