How Many Times Should The Putty Be Scraped When Decorating The Wall?

As we all know, putty is also a wall material, which plays a very important role in interior decoration. But it must be used correctly to achieve the ideal decoration effect.

The main function of putty is to make the wall surface smooth. If the wall surface is not smooth, it will affect the beauty of the interior. Therefore, this article will introduce to you how many times to scrape the wall putty and what is the main function of putty.

How many times should the putty be scraped when decorating the wall?

How many times should the wall putty be scraped during interior decoration? Generally speaking, the putty needs to be scraped twice. The specific steps are as follows:

Wall inspection

Before decorating the wall, the first thing to do is to check whether the wall is firm and flat.

If your wall has cracks or dents, you need to use plaster to repair it and make it flat.

Material preparation

When applying putty on the wall, you first need to protect the furniture in the room to prevent dust from covering its surface and increase the difficulty of later cleaning.

Then apply a layer of concrete interface paint evenly and wait for it to dry before applying putty.

If it is a new wall, you need to ensure that the cement curing period has passed before applying putty, which is about 28 days.

Scrape putty

Generally, the wall only needs to be scraped twice, with at least 2 hours between each scraping.

If the flatness of your wall is poor, you need to scrape it more times. If there are obvious depressions on the wall, you need to find plaster to level it first.

Polishing wall putty

After the putty is polished, it needs to be polished. This step can be done at night. It is recommended to use a 200-watt or higher light bulb close to the wall so that the flatness of the wall can be checked during polishing.

In addition, a lot of dust is easily generated during the polishing of wall putty, so be sure to ensure that the construction workers wear masks.

Apply primer

Clean up the powder produced when sanding the wall putty, then apply primer and wait for the primer to dry.

Apply top coat

Usually, the topcoat also needs to be applied twice.

After applying the first coat of topcoat, you need to wait for it to dry before applying the second coat. There should be a 2-4 hour interval between the two coats.

If the project schedule is not very tight, it is recommended to apply the second coat 1-2 days after the first coat of topcoat.

What is the function of putty?

Beautify the wall

In the painting project, the construction requirements for the wall are relatively high, such as its flatness, smoothness, and fineness.

In particular, some coatings have very high requirements for the smoothness of the wall, so to improve the smoothness of the wall, we must start with the performance of the putty base.

Prevent wall cracks

The surface of buildings is particularly prone to small cracks, which can easily cause peeling and shedding between layers, and even cause water seepage on the wall.

Therefore, the putty layer can avoid the above phenomenon, and they have the effect of crack resistance and crack resistance.

Sealing effect

Flatness can be said to be the most basic requirement when painting the wall, so the caulking agent also has the most basic function. If the wall is not flat during the construction process, the impact can be imagined.

Ensuring the flatness of the wall is the most basic requirement when painting the wall, so the caulking agent also has the function of filling the gap, making the wall smoother and more delicate.
