Five steps of mobile phone photography series course

Building waterproof engineering is a very important work in building engineering, which can effectively prevent water infiltration and protect the structure and service life of buildings. This paper will introduce five construction steps of building waterproof engineering to help you better understand building waterproof engineering.

1 wet base surface

Before construction, the base surface should be completely wet, and there can be no Mingshui. If the base surface is wet, the construction can be carried out directly. This step is the first step of building waterproof project, which is very important.

Preparation of waterproof slurry

Pour the waterproof slurry emulsion and powder into a mixing barrel in proportion, and fully stir until it is even without particles. Let stand for 10 minutes and then stir, the effect is better!

3 besmear brushs waterproof layer

Brush the prepared waterproof slurry on the wet base surface with a brush or roller brush. After the first layer is completely dry (about 2 hours or not sticky by hand), brush it for the second time, and the brushing directions of the two times should be staggered.

4 stirring waterproof slurry

In the process of construction, it is necessary to keep intermittent stirring to prevent mucilage from settling. This step is one of the key steps in building waterproof engineering, and attention should be paid to details.

5 overburden construction

After the waterproof layer is completely dried, it can be used as mortar protective layer or other covering layer. This step is the last step of building waterproof engineering, and it is also a very important step.
