Waterborne wood coatings is a not easy to master the technology, a lot of paint master of waterborne wood paint is not very understanding, often paint way of thinking for the construction, easy to disease caused by a variety of large and small paint.
Underneath, small make up to you about the waterborne wood paint when construction need to be aware of some factors.
1. Waterborne wood paint viscosity control
the same quality of water-based wood coatings, lower the viscosity of the summer than in winter, so according to the construction of temperature adjustment, so as not to affect the quality of the paint film. Before the actual construction, we should advance of waterborne wood paint sample, it won't appear ills as the prerequisite to adjust.
2. Control of the construction environment temperature
waterborne wood paint on the construction of environment temperature, humidity and ventilation conditions are required, general construction environment the best temperature is 25 ℃, should not be lower than 5 ℃ more than 35 ℃, humidity is no more than 85%. In temperature below 5 ℃ or more than 35 ℃, humidity is more than 85% when should stop the construction.
3. Control of waterborne wood paint film
in construction of summer, the weather temperature is higher, should not be when spraying thick coating, because of waterborne wood paint moisture volatilizes quickly, lead to table dry speed is relatively fast, so vulnerable to paint film surface heat rash, bubble and pinhole and other ills, construction personnel should be fully considered when climate factors, reasonable arrangement, avoid unnecessary problems.
4. Waterborne wood paint drying speed control
after construction of waterborne wood paint dry time in 25 - the best table Between 45 minutes. Too short time table dry, paint film is not good, easy to blister on the surface and dry paint film. In construction of waterborne wood coatings, construction environment should be based on wood coatings to adjust the temperature and humidity of the drying speed.
