Epoxy grout manufacturer share of blister is the problem?

epoxy floor paint blister osmotic pressure foaming and foaming coating surface, coating the surface bubbles mainly is the presence of moisture and volatile liquid, coating or surface under high temperature and high humidity in drying process in many uneven size, irregular round vesicular muster the phenomenon: osmotic blistering is mainly caused by water vapor of concrete. Small bubbles in the process of the paint film curing escape when the micro pores. In the process of curing reaction, because of the paint viscosity increased, stomatal small pipes will not closed, and ultimately retained in the dry paint film. No residual air or to paint tables, one way is to choose a good construction, reduce the amount of air into the, but in fact, most of the time of construction methods have been determined by the actual application condition, the method is limited. Second, by adjusting the coating formulation, reduce or eliminate foam. Specific, can be adjusted by selecting low foam raw materials or the best viscosity, can significantly reduce the bubble problem, but this method is often restricted to scheduled in construction of performance index and the viscosity of the coating specification. A bubble caused by the reasons: unfinished closed at the local level. Before or during surface construction did not eliminate and deflated omissions;

processing method: strengthen the inspection and handling at the grassroots level in do before each trowel scratch coating or coating on the surface, after check again, if there is a bubble surface, some area is bamboo broom flat brush, to bubble deflated, must be careful, don't have missing case, is correct after curing coating and then to the next process.
