Interior wall coating construction process:

1.
Basic level inspection and cleaning

Check whether the surface of the base layer has dust, oil, impurities, whether the base layer is firm and firm, whether there are cracks in the base layer, whether it is flat, vertical, and whether it is dry.

2.
Grassroots treatment

Qualified is that the base layer is the guarantee of the beauty and durability of the paint.
It is a common disease that the putty layer and the paint layer cracked due to the base layer factors (such as cement mortar or wall cracking).
In case of cracks in the base layer, bandage treatment is a general method of interior wall finishing construction.
If inferior glue is used on the original white wall, it should be reinforced with anti-alkali primer.
Chalking on the wall should be removed.

3.
Wooden board closure

Avoid surface deformation and color penetration.

4.
Patch the seam and stick the bandage

Ensuring the flatness and firmness of the interface around the mending is the key point for mending.
Sticking two layers of bandages can reduce cracks in the paint layer.

5.
Partially scraping putty

If the flatness of the base is not enough, you need to scrape the putty to level the local unevenness; but when the deviation of the flatness of the base is more than 8mm, you cannot use the putty to level it, and the cement mortar should be used for leveling.

6, smooth

Polish the putty to ensure that the base layer is roughly level.

7, the first full scrape putty

The construction strives not to show the bottom, not to miss the scratch, and not to leave the traces of the joints.

8.
The second full scraping putty

Putty generally survives by scraping twice, and the scraping time of each putty layer should not be too long.
The thickness of the putty is 1~3mm.

9, the yin and yang angles are straight

Ensure that the yin and yang angles are in a straight line.

10, the third time full scraping putty

When there are high requirements for the flatness of the wall, the putty scraping can be increased again, but the thickness of the putty polishing in the last batch scraping should not be less than 0.
8mm.

11.
Fine grinding and smoothing

The paint has higher requirements for the smoothness of the putty layer.
The putty layer should be polished smoothly when sanding, and the putty layer should not be too hard, so that the putty layer is too smooth after sanding, without fine sand marks, which is not conducive to the bite of the paint on the putty layer.

12.
The first primer coating

The function of the primer is to resist alkali blocking.
Reinforce the putty and cover the fine sand marks, so the first coating layer should be eaten through the putty layer as much as possible.

13, compound putty

The putty layer was cracked during the polishing process.
For sand holes, make up the putty after the first coat of paint.

14, smoothing

After refilling the putty, there will be traces left, which should be smoothed to avoid affecting the integrity of the coating.

15.
Second primer coating

In order to ensure the finishing effect of the top coating, the total thickness of the primer should be 30mm.
It should not be greedy to save labor and materials and only apply the primer once.

16, smooth

The leveling of the primer coating is not enough, so it should be polished when the top coating is applied to ensure the smooth surface effect of the top coating.

17.
The first surface coating

The first spraying or roller coating should be uniform, do not try to save labor and spray at one time.
The roller is too thick, which will affect the adhesion.

18.
The second surface coating

Spray the second time.
Care should be taken to maintain after roller coating, and strong ventilation is not recommended, so as to avoid contraction of the coating layer during the ventilation, resulting in coating cracking.
