Roll primer.
After the batch scraping of cement mortar is completed, it needs to be cured for more than 15 days and wait for complete drying; The thermal insulation wall shall also wait for more than 48 hours after the mortar is completed at room temperature.
Spray color dots.
Therefore, most construction masters roll coating twice to meet the construction requirements.
So you see, you can’t save the finish.
Sand in water, as the most popular exterior wall coating, many people do not know its standard construction technology.
The texture and thickness of the spray can be consistent with the color of the sample.

Base treatment.
Therefore, you must not apply alkali resistant sealing primer in order to reduce the cost.
The weather resistance can improve the ultraviolet radiation resistance of the wall, and the waterproof and dirt resistance can make the cleaning of the wall more convenient in the future.
If any, they shall be completely removed, otherwise the adhesion of putty (fine plastering mortar) will be affected.
The main purpose of using the finishing coat is to enhance the weather resistance, waterproof and dirt resistance of the sand in water coating.
Anti alkali sealing primer has the functions of anti alkali and anti salting out, reinforcing substrate, enhancing adhesion, covering putty color and forming grid joint color.
After the mortar is dry, the sharp corners and knife marks need to be removed.
In other words, it can avoid the problem of alkali pan or flower on the sand in water surface caused by the leakage of alkaline substances from the wall.
Apply putty.
The intermediate coating can enhance the adhesion of the finishing coat after rolling coating, and can also cover the color of the alkali resistant sealing primer to avoid the primer color affecting the overall decorative effect of sand in water.
The rolling coating must be uniform.
The color dots are generally sprayed twice.

Roll coating finish.
Tear the textured paper.
After the first surface is dry, spray the second time.
After spraying sand in water, the textured paper shall be torn off immediately to avoid that the textured paper cannot be torn off after drying or the integrity of the paint surface is damaged when tearing the textured paper.
After the primer is completely dry, snap the line according to the size required by the designer, paste the textured paper according to the part where the line is snapped, and gently press the textured paper to avoid falling off.
