The construction quality of epoxy floor paint depends on three parts of the material and seven parts of the construction. If the construction technology of high-quality floor paint is not strictly followed, it will not get good results. Therefore, the construction of epoxy floor paint is very important. In the construction process, because the environmental temperature and humidity are often uncontrollable, floor paint in large-scale construction, often has a great dependence on environmental conditions. The following epoxy floor paint manufacturers will explain the impact of humidity on the construction of epoxy floor paint.
Humidity refers to the content of moisture in the air, which is generally expressed as a percentage. If condensation occurs, the relative humidity of air reaches 100%. According to the construction requirements of epoxy floor paint, when the relative humidity of air is higher than 85%, the construction of epoxy floor paint can not be carried out, because it is prone to white, cracks and other defects. Except for wet curable polyurethane coatings.
Humidity not only affects the construction of epoxy floor paint, but also affects the curing of the floor paint. When the humidity index is too large, it affects the floor paint. Its influence is often greater than people imagine. Excessive humidity will cause dew on the surface of the coating. Condensed water will destroy the curing agent and cause the phenomenon of whitening, loss of gloss, sticking and Re-sticking of the coating, which will greatly reduce the decorative effect of the surface and cause rework in serious cases. Especially solvent-free topcoat, the surface drying time is generally longer. It is dangerous to paint when it rains immediately after painting or in the evening of winter and spring. But sometimes because the owners require time limit, ideal weather conditions are not easy to appear, then measures need to be taken to improve the painting environment, such as opening air conditioning heating and dehumidification.
