Can I brush latex paint in winter? Is it too cold in winter to affect the quality of latex paint?

It is not advisable to brush latex paint in winter, and the temperature should be above 5℃. Otherwise, the quality will be affected.

The minimum film forming temperature of latex paint is 0℃. When painting, the paint film is thin, which is easy to freeze and destroy latex particles in cold environment, and the film forming environment is low, which easily leads to incomplete film forming. The film formation of latex paint is a slow process, and it can only be formed at 25℃ for 7 days. Therefore, cold and rain should be avoided during film formation.

In the process of brushing latex paint in winter, the wall will crack and fall off. This is because the winter weather is cold, and there is moisture or condensation on the wall or surface. If the wall paint or primer is brushed directly without treatment, small bubbles will be formed and cracked when the temperature rises, which will lead to peeling and peeling of the wall in the later stage of construction.

structure

Latex paint is a water-based paint, and its film performance is much better than that of solvent-based paint. The organic solvent, which accounts for half of solvent-based coatings, is replaced by water here, so the toxicity problem of organic solvents is basically solved by latex paint. Latex paint is made of some polymer aqueous solutions.

In addition to water and different types of polymers or safe and harmless polymers, it also contains a small amount of emulsifier and a small amount of unpolymerized free monomers. Free monomers are small molecules that can be volatilized, and there are different degrees of toxicity problems. The concentration of free monomer in environmental protection paint is controlled below 0.65438 0%, and the dosage of additives is 2% ~ 3%. Less than 0.05% to 0. 1%. Healthy.
