Wood paint construction is a very testing technical work, especially oily wood paint, which is composed of thinners, curing agents and main paint three parts, in the construction, need to be in accordance with a certain proportion of the hook mixing can be painted.
, in addition to the oilman's operating technology, construction temperature, wood paint viscosity, brush thickness, drying speed and other factors will affect the quality and effect of construction.
1
the temperature and humidity of the construction environment
before the construction of wood lacquer, the site environment should be tested, wood lacquer construction on the site of the construction environment of temperature, humidity and ventilation conditions have certain requirements
.
generally, the construction temperature must not be lower than 8 degrees C, and not higher than 35 degrees C (the optimum temperature is 25 degrees C), the maximum humidity should not exceed 85% (at less than 70%). If the construction site environment is not up to standard, the construction should be stopped.
2
the viscosity of the wood paint
the same quality wood paint, the viscosity in summer is lower than in winter. Therefore, in the deployment, should be in accordance with the temperature at the time of construction to adjust the ratio of thinner addition, so as to adjust the viscosity of wood paint, to ensure the quality and effect of construction.
, it should be noted that if the ambient temperature is too high and the amount of thinner is not added enough, the quality of the paint film may eventually be affected.
refore, before starting construction, wood paint and thinner ratio test should be carried out in advance, reference to the product description, to paint film will not appear ill as a prerequisite for matching.
3
wood paint brush thickness
summer coating construction, due to the high temperature of the weather, operation need to pay special attention to brush thickness, should not be thick coating.
due to the rapid volatilization of wood paint solvents, resulting in a relatively fast drying speed, if the paint film is too thick, it is very easy to lead to the surface of the paint film bubbles, pinholes and other ills.
construction personnel should take full account of climate factors, reasonable arrangements to avoid unnecessary problems.
4
the drying speed of wood paint
the best drying time after wood lacquer construction should be between 25 and 45 minutes. Table drying time is too short, easy to lead to paint film foaming, hanging, dry, wrinkle and other ills.
in the wood paint construction, should be based on the temperature of the construction environment to adjust the drying time of each process, in order to ensure the construction quality and final effect of painting.
