Can you make sandpaper the next day after scraping putty

Under normal circumstances, no one can be accurate about how long it can be polished.

It depends on the thickness of the putty, if the wall is uneven and the putty is used too much, the drying time will be increased accordinglyThere is also depending on the weather, if the weather is sunny and the temperature is high, the putty will also dry faster, if it is in a rainy day, the air humidity is high and the temperature is low, then the putty is very difficult to dry at this time;Under normal circumstances, the thickness of the putty is uniform and the weather is good, and the drying time of the putty is about 2 days before it can be polished.

Under normal circumstances, the construction of the first layer of putty is 3 days, and its drying period is about a week;The construction of the second layer is about 2 days, and the drying period is 3 daysThe third layer is finely processed for about 2 days, and the drying period is also 2 days, and it can be polished.

Scraping putty is generally dry in 1-5 days.

Scraping putty mainly depends on the season and weather, generally in spring and autumn, when the weather is relatively dry, it can be dried in 1-2 days, and it will be at least 3 days in summer, because although the temperature in summer is very high, the surface moisture evaporates quickly, but the humidity is large, so most of the time the section is only dry on the surface, and the winter is relatively cold, it takes days to dry, pay attention to the rainy season, the time is longer.

Batch putty scraping on the wall usually needs to be scraped two or three times, and it is necessary to wait until the previous putty is completely dry before the next putty can be done. After the putty is scraped, the whole wall must be smooth and smooth, the texture is uniform, and there are no scratches on the surface, otherwise it will seriously affect the overall decoration effect.

Preliminary work for scraping putty

There are different construction requirements for the base treatment of different walls, for example, the wall surface of cast-in-place concrete often has some porosity and bulging phenomenon, so the wall should be repaired and smoothed first, and the protrusion should be smoothed and the depression filled. If it is a precast concrete wall, there will be some grit and pimples on the surface, so it is necessary for professional construction personnel to use a wire brush to brush the wall as a whole to remove these debris.

After the wall is treated with a base layer, there will still be some depressions in the wall, so it is necessary to use gypsum putty to fill the depressions. Note that when gypsum putty is prepared, the weight ratio between gypsum, emulsion and cellulose aqueous solution is about 100:5

60. After adjustment, the gypsum putty is compacted into the depression, and the vertical batch is scraped horizontally to ensure the smoothness of the wall.

In the normal construction process, after the first putty scraping is over, it must wait until it is dry before scraping the second putty, and 48 hours can ensure that the putty layer is drier, and it is less likely to cause the problem of peeling and falling off.

Scraping putty refers to the most important step in the treatment of the base layer by filling or overall treatment to remove the uneven part of the surface of the base layer and keep the wall flat and smooth.

Scrape the putty at the first time, wait for the putty to dry for the first time, and then brush the putty for the second time, and then wait for the putty to dry and check it, and then refill the putty again. Then scrape the putty again again, this time it is very critical, be sure that the variety is not too thick. Wait until you have the clubhead sanded flat, then apply the paint all over again.

It is also best to apply the paint three times.

As long as it dries thoroughly, it can be done man-made or environmentally.

When it's dry, you can shave it a second time.
