How to choose a proper form release agent with concrete?
There are major two kinds of form release agent: water base and solvent-oil base. Water-base type can apply for concrete casting in roof-protection factory. There are two types of water base: ready-to-use and diluted with water in concentration. The another type is solvent oil-base that can be applied both in-door and out-door factory.
