It is estimated that we have heard that winter is not suitable for floor paint construction, so what problems will arise, we encounter problems in winter construction and how to do?
01, the surface paint cracking phenomenon
such a problem, is undoubtedly the low temperature environment curing time is longer, and the construction time interval has not been extended, the paint is not dry to do the next process.
02, floor paint thickness
winter floor paint construction personnel should pay attention to coating thickness should not be too thick, the greater the thickness, the more difficult it is to completely cure.
although the construction of epoxy floor paint in winter is difficult and the quality is difficult to ensure, if the project does need to be constructed in winter or low temperature environment, the following methods can be used to
.
01, separate the low temperature period
Epoxy floor paint construction, try to separate the low temperature period, after 10 a.m. to start construction, 3 p.m. to stop construction, reduce the impact of low temperature.
02, increase the room temperature
increase the room temperature, the temperature to more than 5 degrees, so that can also be in winter construction. Many plants in the north have heating, which can be opened before and during construction.
03, add solvent
can add less than 5% of the volatile rate of faster solvents, such as acetone, ethyl acetate, butyl acetate and so on. This can solve the problem of large viscosity and lack of leveling in the floor paint at low temperature.
04, paint heating
the paint in a warm environment, or with steam, hot water heating. However, be careful not to let steam or hot water into the coating, and the hot water temperature is controlled below 38 degrees.
the construction of epoxy floor paint at low temperatures in winter!
1, fog should not be suitable for construction
if the construction site is not sealed space, encounter fog or frost and snow and other climate, can not be constructed. If the surface of the floor is covered with water vapor, it is not appropriate to carry out construction. Otherwise, the coating is prone to whitening and sticky.
2, extend the construction interval
winter low temperature environment, the floor paint curing time is longer, so the time interval between the construction process needs to be extended, must determine the coating film is really dry and then the next layer of construction, otherwise it is easy to seepage, coating film de-layering and other coating problems.
3, pay attention to fireworks
winter cold, workers are used to smoking or fire heating, this time must pay attention to safety awareness, do not fire or smoke near the paint pile, otherwise once ignited, barrel paint may cause an explosion. New Year's Day, be careful of fireworks, away from the accumulation of paint, so as not to cause unnecessary losses.
