The old wall is so dirty that I want to scrape putty again. Does the putty on the old wall need to be removed? Can you scrape a new layer on the original putty?

Some netizens asked Bian Xiao before: Do you want to invite a master to paint the old house? Can I brush it myself?

Of course, you can paint the wall yourself, but you need to master some basic knowledge. Here, Bian Xiao spent some time finishing a painting process commonly used by masters, hoping to help the owners who want to paint themselves.

Step 1: Level the wall.

Shovel away the damaged, peeling and loose parts of the wall, and keep it dry and clean.

Step 2: Apply plaster on the wall.

Use a scraper to evenly coat the wall patching paste on the wall to be repaired. Thin repair positions can be smoothed at one time, and thicker positions need to be brushed several times.

Step 3: After 12 hours, polish with sandpaper.

After the plastering of the patching wall is completely dry (usually 12 hours), gently polish it with sandpaper.

Step four, paint the wall.

Apply the repair paint evenly on the repaired wall, and then apply the repair paint after it dries.

After the above four simple steps, the repaired old wall is basically done.

Precautions:

1. The putty needs to be scraped twice, and the last putty can't be scraped before it is dry.

2. Before painting, it is necessary to take protective measures for other places that do not need painting.

3. Be sure to choose a high-quality permanent brush.
