Inquiry (采购产品): kao-seal i will use kao-seal to combat alkali hydrolysis on lightweight refractory guniting and castables. The instructions from my advisor is to apply after initial set, which is before the heat created by the curing cycle. Will the steam produced by curing under plastic covers destroy the kao-seal? I am also making walls and corbels by pouring into vertical shutters. How and when do I apply the kao-seal.
