Wood coatings construction is a very technical work, in addition to workers operation technology, construction temperature and viscosity of wood coatings, the coating thickness, drying speed and other factors will affect the quality and effect of wood coatings construction.
Although waterborne wood coatings than oily wood coatings construction is simple, but also cannot ignore these four 'degree'!
a, the temperature of construction environment humidity,
in wood coatings before construction, should be on the scene environment for testing, in general, the construction shall not be less than 8 ℃ temperature, at the same time shall not be higher than 35 ℃ ( The best temperature is 25 ℃) , humidity should not exceed 85% ( Is better to less than 70%) 。 If the construction site environment not up to standard, should stop the construction.
2, wood coatings preparation viscosity
the same quality of wood coatings, the viscosity of the lower viscosity in summer than in winter. When allocate accordingly, should according to the temperature at which the construction to adjust the proportion of adding diluent, so as to adjust the viscosity of wood coatings, ensuring construction quality and effect.
3, the thickness of the wood lacquer besmear brushs
coating construction in summer, the weather temperature is higher, when special attention should be paid to coating thickness, unfavorable thick coating. Because carpentry lacquer solvent volatilization rapidly, therefore lead to table dry speed is relatively fast, if besmear brushs paint film is too thick, easy to cause film surface air bubble, pinhole and other ills. So the construction personnel should fully consider the climate factor, reasonable arrangement, avoid to produce needless issue.
4, wood paint drying speed
the best table dry wood coatings after construction time should be between 25 ~ 45 minutes. Table dry time is too short, easy to cause film blister, sagging, dryness, wrinkling, etc. So in wood coatings construction, should according to the temperature of construction environment to adjust the drying time of each process and assure the construction quality of the coating and the final result.
