PLEASE NOTE: DO NOT fiberglass when the ambient temperature is below 15°C as it will result in under curing of product.

All Resins including, Pool-coat must be catalyzed with catalyst/hardener before use.  This will initiate the curing process. The minimum quantity of catalyst is 1% of the weight of the resin or pool-coat being used and the maximum is 3%.

Thus, if the level of the catalyst is too low the lining will not adequately cure and water, chemical and weather resistance will not be fully developed.

Stir the catalyst in thoroughly – ideally 30 mixes to the left and 30 mixes to the right.  The hardening process begins immediately so only catalyze a working quantity or your mixing container will soon be full of solidified resin.

Once catalyzed the resin it will gradually cure taking on a jelly-like consistency in about 10 – 15 minutes, before becoming hard in about 30 – 40 minutes at room temperature (about 20°C).  The curing process generates heat within the resin.  Best to do your mixing in stages to prevent material loss.

Care should be taken to protect un-gelled and freshly gelled surfaces from rain and dew.  Contact with moisture at this stage can be the cause of white, water marks on the surface of the pool-coat.

IMPORTANT: the pool must not be filled with water until the pool-coat has fully cured.  At least 5-6 days in summer and 7-10 days in the winter
