In general, wood lacquer besmear brushs quality will directly affect the overall effect, therefore, wood coatings construction is very important.
At the time of construction, according to the proportion of blended mix after can brush paint, but there will be some factors will affect the construction quality.
Underneath, small make up take you to see: besmear brushs wood coatings need to strictly control the four points.
1, wood paint viscosity
with the quality of wood coatings, the lower the viscosity of the summer than in winter, so when with lacquer, should according to the temperature at which the construction, adjust the thinner, the proportion of added to control the viscosity of wood coatings. If the environment temperature is too high, add the amount of thinner is not enough, may affect the quality of the paint film. Therefore, before the actual construction, matching test first, on the premise of it won't appear ills.
2, construction environment
wood coatings on the construction of environment temperature, humidity and ventilation condition has certain requirements, general wood coatings construction environment the best temperature is 25 ℃, the highest no more than 35 ℃, humidity no more than 85%. The temperature more than 35 ℃, or more than 85% when humidity should stop the construction.
3, film thickness,
construction in summer the weather temperature is higher, when spraying shoulds not be too thick, because rapid evaporation easily lead to table dry speed is relatively fast, coupled with spray paint film is too thick, so vulnerable to paint film surface heat rash, bubble and pinhole, construction, climate factors should be considered, and the reasonable arrangement, avoid unnecessary problems.
4, drying time
wood coatings after construction best table dry time at 25 Between 45 minutes. Too short time table dry, paint film is bad, blister easily on the surface and dry paint film. Wood coatings construction, should according to the temperature of construction environment, adjust the speed to dry wood coatings.
