Why do workers take a light bulb and scrape it when scraping putty powder for the last time?

Latex paint. It is also latex paint.

Latex paint is a water-dispersible coating, which is made of synthetic resin emulsion as the base material, and then added additives after grinding and dispersion. Scrape putty when we renovated our new house.

It mainly plays the role of a foundation, and he also mainly fills the gaps in the wall better, so that we can better and more evenly paint the wall when we paint latex paint in the later stage.

If we scrape putty on the wall, to be honest, there will be a lot of scratches or smears on the wall, which is very unsightly, and the putty powder on the wall.

It is also easy to fall off the powder, and the color looks very uncomfortable, but if we only paint latex paint on the wall, then there will be a lot of black holes on the wall, and the decorative effect is also very poor, and it is also a waste of material when painting latex paint. I have seen a lot of wall decorations without latex paint after scraping putty, and more than 90% of the self-built houses in rural areas are putty straightforward, including my own home is also decorated like this, and the effect is not as bad as some people say? Just as slippery, white and bright!

Ordinary putty is actually a decorative material for leveling the surface of the wall, such as the uneven roof at home, the wall is not straight, the wall is damaged during decoration, and the air conditioning duct eye can be leveled or filled with putty. Waterproof putty is mainly used in home decoration kitchens or bathrooms, as well as hotel bathrooms and places that are easy to be wet.

You can't use ordinary putty powder, ordinary putty powder is easy to crack, burst skin, and the appearance of waterproof putty is a good solution to the problem that the bathroom can also be used for gypsum board ceilings.

After scraping the putty to dry out, it is necessary to polish and repair, generally now the grinding is used by the machine, there are also sandpaper sanding, it is more laborious, the grinding and repair is repeated, generally two or three times on it, waiting for the dry two or three days after you can brush the latex paint.

Because the specific effect can be seen in this way, the putty powder will be smoother and there will be no bumps.

Mainly because of the illumination of the light, you can see the uneven place of the putty, so that the putty can be scraped more flat.

Because this is to see if the walls are evenly plastered, because it is not clear to the naked eye. It will be seen a little more clearly under the bulb.
