Polyester laminating resins are generally used with glass matt reenforcement to build thin, strong layers for the construction of molds, back-up molds or objects. The resin is weighed out and after the addition of a small amount of MEK catalyst ( 2% - 4%) it starts to gel and finally harden. The more catalyst you add, the faster the curing (hardening) process goes. Do not mix more than you can comfortably handle in 15-20 minutes. For larger surfaces mix multiple batches and work "wet in wet". Build up a thickness of at least 3 layers of glass by cutting small patches and put them overlapping on the surface of your mold/model. Impregnate the resin by dabbing with a brush. Wet out the glass mat but do not use excessive amounts of resin. For a standard square meter of 300 grams mat you should use ca. 800 grams of resin.

materials needed

• Polyester Laminating resin (our standard sets include catalyst)
