Construction process

1.

(1) Materials and tools: 200-mesh sandpaper, oil stone or angle grinder;

(2) Check the base layer first, remove floating particles and residues on the surface to ensure that the surface is clean, free of loose objects, and no moisture;

(3) Perform all-round repair treatment on the small surface cracks, blisters, and small damage to the external corners;

(4) For the repaired area, sand with coarse sandpaper to ensure that the texture is consistent with the large area after repairing, and clean up the floating dust to ensure a firm combination of the finishing layer and the base layer .

Acceptance criteria: firm surface, no loose objects, no cracks, clean, dry, no dampness, no blisters, no hollow drums, no mortar bumps, no obvious bumps and other phenomena, no oil, floating ash and other pollutants

2.

(1) Use waterproof putty on the anti-cracking layer mortar for leveling.

(2) Putty should be blended on site, mixed evenly, in the form of toothpaste, and should be used up after blending

(3) During construction, use a spatula to apply the putty evenly on the base surface.

(4) After the putty is dry, polish it until the surface is smooth without scratches, and remove the floating dust.

(5) After the putty is dry, the next process can be constructed

Acceptance criteria: The surface is smooth, uniform, clean, free of scratches, cracks, straight, square, and free from floating dust and other debris

3.

(1) After the surface treatment of the base layer, it should be carefully checked to confirm that it meets the requirements.
After the moisture content of the base layer is detected to be less than 10%, the base layer sealing wall primer construction shall be carried out;

(2) Before the base layer is sealed, the doors and windows, air-conditioning brackets and other metal parts should be wrapped and covered as necessary, and removed after the overall spraying is completed to prevent pollution and rust;

(3) Before construction of the base seal primer, it should be diluted in strict accordance with the dilution ratio specified by the product.
Note that the primer should be fully stirred during dilution to ensure uniformity;

(4) Primer can be applied only after the putty is dry;

(5) 4-6 hours after applying the primer, it will enter the next process; acceptance criteria: even spraying, no leakage, no leakage, no sagging
.

4.
Grid stitching elastic thread

The wall is divided according to the requirements.
When dividing the whole cell from top to bottom at the same time, to ensure that the surrounding gray seams are on the same horizontal line, and all vertical gray seams are parallel to each other and vertical.
To the ash seam horizontal and vertical
.

Acceptance criteria: horizontal and vertical lines, double parallel lines with consistent width and narrowness, clear and clear
.

5.
Apply the split paint

The slit paint is used to paint the slits.
In order to ensure that the slits do not show up, the width of the slit paint can be appropriately wider than the design to ensure that the slits are full within the width of the slits
.

Acceptance criteria: The paint should be horizontal and vertical, the width and the width are the same, and the depth is the same.
The interior division and seam paint is full, the effect is clear, and the bottom is not exposed, no skin, and does not pollute other parts
.

6.
Secondary elastic thread

Since the elastic line of the first division seam has been covered after the division seam paint is applied, in order to make the tape division strip straight, it is necessary to carry out the second elastic seam and only need to pop out the side seam of the division seam
.

7.
Paste split-seam masking paper

When the masking paper is pasted, just align it with the elastic line of the second division seam
.

Acceptance criteria: The masking paper is pasted firmly, tightly, and straight, and it will not damage the grid line or stick to the seam paint
.

8.
Real stone paint spraying

(1) The real stone paint should be diluted in strict accordance with the dilution ratio specified by the product, and the real stone paint should be fully stirred during dilution to ensure uniformity;

(2) When spraying, apply in order from top to bottom;

(3) The paint should be connected to the grid line or window cover during construction to avoid color difference in the joint;

(4) In the construction of different real stone paints, the construction of one kind of real stone paint should be completed and the surface is dry before the construction of another color of real stone paint can be carried out.
During the construction, the real stone paint of another color should be protected to prevent pollution;

(5) The real stone paint must be thoroughly stirred evenly before use, and the lid of the bucket should be tightly closed during the construction gap to prevent the coating from skinning;

(6) The spraying method is used for construction, and a test spray must be carried out before construction to determine the nozzle used, working pressure, spray gun moving speed and other construction factors to ensure the quality and effect of the application
.

Acceptance criteria: uniform spraying, uniform thickness, uniform color, uniform particle point, size meets the requirements, no bottoming, no spray leakage, no flow, etc.
, no accumulation of materials at the inner corner, no pollution to other parts such as doors, windows, and glass
.

9.
Real stone paint polishing

Before spraying the waterproof protective film on the real stone paint, use ordinary 400-600 grit sandpaper to grind off the floating sand and the sharp angles of the sand particles on the surface of the dried coating to increase the beauty of the natural stone paint surface and ensure the complete coverage of the protective film
.
Don't use too much force, otherwise, it will damage the paint film, cause the bottom to loosen, and in severe cases, it will cause poor adhesion and the real stone paint will fall off
.

10.
Tear and peel off grid textured paper

(1) Before peeling off the tape, use a paper cutter to cut the tape at the vertical and horizontal junctions, and cut the vertical tape in a direction parallel to the horizontal tape to prevent the real stone paint from falling off when peeling off the tape;

(2) Uncovering time control, the faster the uncovering time, the better, shorten the time as much as possible, so as to prevent the surface of the real stone paint from crusting and breaking
.

(3) The direction of uncovering the paper, opening the line at nearly 180 degrees
.

11.
Split seam processing

After the split seam treatment tape is peeled off, the ash seam should be sorted and repaired to ensure that the ash seam is straight and the width is consistent.
When repairing, avoid secondary pollution
.

12.
Roll coating dust cover topcoat

(1) After the construction of the real stone finish, the surface of the coating is hard and dry, and it should be dried for more than 24 hours on a sunny day.
The drying time should be extended in rainy and cloudy days before the finish paint spraying construction can be carried out;

(2) The finish paint should be diluted in strict accordance with the dilution ratio specified by the product, and it should be fully stirred during dilution to ensure uniformity;

(3) Roll coating construction should be carried out in order from top to bottom;

(4) The paint should be connected to the grid line or window cover during construction to avoid color difference at the joint;

(5) Spraying or rolling method can be used for construction
.

Acceptance criteria: uniform finish, consistent color, no leakage, no sagging, no bottom leakage, no accumulation of material at the inner corners
.
