Functional paint meaning geometry

What is the practical significance of functional coatings for home improvement projects? After use, can the general wall problem be completely solved?

Waterproof coating: The most important property of the waterproof coating is that it can be wiped with a semi-moist rag. The paint with poor waterproof properties will fade after rubbing, while the paint with good water resistance can withstand multiple rubs. If such paint is applied to places where the water vapour such as the kitchen or the bathroom is heavy, the paint can be prevented from powdering due to moisture.

Alkali-resistant paints: The anti-alkali properties of paints are very important, because the walls are made of concrete and have high alkalinity. If you paint ordinary paints, the wall surface will change flowers shortly after use. Although the current construction team will apply a putty to the wall, even if it is waterproof putty, it is also highly alkaline, and the PH value can reach 10 or more. Therefore, it is necessary to purchase anti-alkali functional coatings.

Anti-mildew coating: Although the climate in the northern part of the country is dry for a long time, high temperature and high humidity are also encountered in summer, and mildew easily occurs on the walls. As a matter of fact, any wall with dew-forming phenomenon will develop mildew when the humidity reaches above 70% and the temperature reaches around 25°C. The use of mildew-proof coatings can reduce the chance of mildew on the walls, but this is only relative, and it does not completely eliminate such phenomena, so consumers do not have to believe too much about the propaganda of the business.

Anti-crack coating: The role of anti-crack coating is to prevent the paint from cracking caused by shrinkage. In fact, now whether it is a functional coating or an ordinary coating, as long as it is a qualified product, it has anti-cracking function. As for the propaganda of the business, it can cover up small cracks on the wall and other arguments, mainly for the second-hand decoration of the old house, but if the wall surface is not fully eradicated clean putty layer, then its cover effect is also very limited. For the new house decoration, the construction team will have to deal with the wall in a comprehensive manner, so the paint is not significant for crack resistance.
