5 after the base course is treated, the coating shall be applied In case of hollowing, sanding or cracking of the base course, the base course shall be treated firmly, fully dried, and then painted, otherwise the waterproof quality and service life will be affected.
If the closed water test is qualified, the protective layer shall be made on the ground first.
Once the water is closed at this time, the waterproof is equal to white.

Ten precautions for coating waterproof construction 1.
7 do not add other substances into the waterproof coating at will The proportion of waterproof coating is strictly tested.
After the installation of sanitary ware or the cement of ceramic tile is fully hardened, try to do another water storage test in order to check whether there is secondary damage to the waterproof layer during the paving process.
In addition, long-term exposure will also reduce the service life of the coating.
Therefore, before the roughing layer is applied with waterproof paint, the burr shall be leveled first, and it is better not to stab the hand.
After the construction of waterproof coating, a protective layer shall be made to avoid damage to the waterproof layer caused by later construction There is no protective layer on the surface of waterproof coating, which will be damaged by cross construction in the later stage, resulting in the failure of waterproof layer.

Closed water test shall be conducted after the waterproof layer is cured When the waterproof coating is not cured, the waterproof layer is still in reaction.
The one-time brushing is too thick.
8 the newly made plumbing on the ground shall be laid on the waterproof layer It is suggested to lay the newly made water pipe and heating pipe on the waterproof layer.
It is recommended to fully spray water for wetting, and some base surfaces even need to be coated.
The brushing times and thickness of waterproof coating shall meet the design requirements The coating construction should not only have the requirements on the number of times and the direction of cross brushing, but also the thickness of each time is very important.
If they are not plastered with rounded corners, stress concentration is easy to form, resulting in cracking of waterproof layer and water leakage.
Putting clean water for closed water test will damage the waterproof layer and easily cause the waterproof layer to shell and fall off.

After the surface is dry and solid and the film is formed, the internal coating has not been completely dry and solid.

In case of leakage, it will not affect other residents.
If the burr is broken, the position is a small hole.
If the coating is directly poured on the ground and applied casually in order to save trouble, each part is thick and thin, and the drying speed must be different.
10.
When there is open water in the base course, it is not allowed to apply waterproof coating directly When the base is clear water, it will dilute the waterproof coating, resulting in uneven emulsion, changing the ratio, and forming a whitening surface.

Adding water and other substances changes the product proportion, the quality cannot be guaranteed, and the waterproof effect is reduced.
If there is an empty drum in the roughing layer, the empty drum part shall be removed first.
The coating construction must be brushed again and again according to the process requirements.
The surface of the thick part is dry and the lower part is still paste.
2.
Do not paint directly on the roughening layer In this way, there are hidden dangers in brushing.
The base pipe orifice, internal corner and other parts shall be plastered into circular arc angle Rounding the internal and external corners is an important step to avoid potential waterproof hazards, because the sharper the edges and corners, the more fragile the waterproof, and the more prone to problems.
