Before the construction of epoxy flooring, concrete foundation treatment is carried out, and checking the moisture content of concrete foundation is one of them. Concrete base is easy to absorb water molecules. Excessive water content will affect the bonding force between floor paint and base, and alkaline substances in water will cause the performance of floor paint to be destroyed, and may cause the whole epoxy floor system to affect its firmness after finishing painting, resulting in floor blistering, delamination, failure and other phenomena. To make epoxy floor for underground garage floor, the moisture content of base floor should be tested. The following methods are introduced:
Method 1: Use 45 * 45 cm transparent plastic film to spread the floor and seal it with tape. After 16 hours, if there are droplets or concrete blackening on the inner wall of the film, the water content is high and it is not suitable for construction.
Method 2: Use a dry newspaper, then cover it with a flat plate, and take it out after 24 hours to ignite, the water content of the flammable is qualified; the intermittent flammable, wet, must choose high permeability primer or water-based materials; the flammable, can not be constructed.
