Precautions for use of waterproof coating

The application of waterproof coating has a great relationship with the condition of the ground base. The more uneven the base is, the more coating will be used. Therefore, before applying waterproof coating, it is better to simply treat the base course and try to level the base course as much as possible. Secondly, the ground should be dust-free, soil-free and oil-free. The pier cloth can be used to drag the ground carefully to remove all the dust. Otherwise, it will lead to the cracking and peeling of the waterproof coating and affect the waterproof effect.

The choice of products depends on the nature of the products, and the names of waterproof coatings sold on the market are various. For example, slurry, mortar, etc., there are also waterproof coatings which are divided into I type and type. Some people say that I is more suitable for indoor use. But according to the relevant professionals, the most important thing is to see the nature of waterproof coating, generally it will be tagged; general type; or flexible type, then look at the ratio of mortar to emulsion, such as 12kg+8.. There are product marks; kitchen and bathroom special in fact, this is just a gimmick, general indoor waterproof coating can be used for kitchen and bathroom.

With the continuous development and test of waterproof materials, the final effect of polymer cement waterproof materials is very good, and the construction is relatively convenient, and the maintenance time is also very long. Generally, there will be no problems in about 20 years. The specific construction points are as follows:

1. The construction shall be carried out under the temperature above 5 ° C, and it is estimated that the construction is not suitable for precipitation within 24 hours.

2. Painting shall be carried out crosswise and vertically, with an interval of 4H

3. If there are special requirements for coating, the number of times of surface coating can be increased.

4. During construction, the air humidity is particularly high and the temperature is low, so the drying time should be extended appropriately.

5. If the temperature of the construction site is high, the water volume can be increased properly during mixing to reduce the construction viscosity
