Construction method: The first step is to lay the foundation, smooth the ground and wall with cement, and dry it to make the wall and ground free of water, ash and oil. The second step is to apply the primer, with the aim of increasing the adhesion of the base surface to the waterproof coating.

The third step, after the primer is dry, the waterproof coating layer is brushed, and at least two horizontal and vertical constructions are required. Fourth, after the waterproof layer is completely dry, the leak test should be carried out, and after confirming that it meets the requirements, the water on the waterproof layer can be sucked dry for the next step of construction.

Cement mortar waterproof material is the most common bathroom waterproof material, which is matched with cement mortar in a certain proportion to form a uniform liquid. When batching, stir with a stirrer, slowly add powder and mix while stirring, and add an appropriate amount of water to adjust the viscosity. It is best to add water before adding powder, and stir well until there is no precipitation.

It should be noted that the prepared ingredients should be used up within an hour.

The thickness of the first coat is required to be more than millimeters, and the corners of the wall and around the water pipes should be painted first, and then the surface will dry after 4 hours at normal temperature, and then a comprehensive painting will be carried out. In this process, it is necessary to pay attention to the waterproof coating evenly coated, and there should be no leakage, bubbling, cracks, falling off and other phenomena.

As for the time required for this process, it still depends on the paint you use, anyway, everyone just wait patiently. When you start painting, you should first brush the façade and then the plane, and the direction of painting between the plane and the façade is perpendicular.

When the last coating film is semi-cured, the coarse sand can be thrown and the good grains can be combined, so that it can be combined with the cement mortar in the future construction.

3. Lay a protective layer

The protective layer is laid to prevent future construction from destroying the current waterproof layer. The protective layer must be completely covered with the waterproof layer, and the combination with the base layer should be firm, so that there should be no omission, and there should be no blistering, cracks, falling off and other phenomena.

4. Water seepage test

This step is the acceptance of the project after it has been completed. When conducting the experiment, the water at the highest point can not be less than two centimeters, and it should be stored for more than 24 hours, and then go downstairs to see if there is any leakage, if no leakage is found, then the project is qualified, and the floor tiles can be pasted.

Precautions

Second, the grassroots hole needs to be painted with waterproof paint in the absence of open water.

The main purpose is to prevent the liquid from being over-diluted, affecting the viscosity and covering power of the coating, and even causing the coating to be unable to form a continuous coating film. Third, the single construction painting is not old and the crack should be brushed too thick. If the waterproof coating is too thick at one time, it will cause the drying to slow down, and it is easy to have a different dryness between the surface and the inside.
