Works great for making your own hopper loads, rocks, or other molds. This ready-to-use Latex Rubber is formulated to be thin enough to seek detail and thick enough to be durable. Create long-lasting molds with just a few coats.

I am using Latex Rubber and it won't dry. What am I doing wrong?
You may be applying it too thick. Latex Rubber should be applied in thin layers, letting each layer dry completely for approximately 30 minutes (dry time varies due to environmental conditions). When applied, Latex Rubber is opaque and off-white in color. It is pale yellow and slightly translucent when dry.

Can latex rubber be thinned? How do I clean the applicator brushes after using it?
It is best to not thin the Latex Rubber. Adding water could change the make-up of the product. It is thick by design to adhere to vertical surfaces.
Brushes should be cleaned immediately with warm, soapy water, then rinsed well. If the Latex Rubber dries on the brush, there is no way to remove it.

I have just started making my own rock molds. The Latex Rubber product says to apply each coat and let dry before the next one. What is an average drying time (it's hot and dry here)?
Latex Rubber should be applied in thin layers. Dry time is approximately 30 minutes, but can vary due to environmental conditions. When first applied, it is opaque and off-white in color. Latex Rubber is dry when it has turned pale yellow and is slightly translucent.
For durable, long-lasting molds, apply at least three coats of Latex Rubber, placing gauze strips between each layer. Clean paintbrush between coats with warm, soapy water.

I made a mold with your Latex Rubber. What do I use as a release agent for my mold?
Before applying Latex Rubber to the item you want to make a casting of, apply a thin layer of petroleum jelly to the object.
Before pouring plaster into the Latex Rubber mold, spray the mold with wet water (mix 1-2 drops liquid dish soap in 8 fl oz water).

Is your Latex Rubber pre-vulcanized?
Latex Rubber is prevulcanized, it does not require heat to cure.

Will Latex Rubber create heat while curing? I plan to apply it over styrofoam to make and mold and wonder if it will melt the styrofoam.
Latex Rubber does not generate heat while drying. However, it will adhere to the Styrofoam and you will not be able to remove the mold. To make a mold using these products, the Styrofoam should first need be sealed with acrylic paint. When the paint is dry, a release agent (such as petroleum jelly) should be applied to the piece.
