Silicone Waterproofing Agents: A Guide to Application

1. Base Surface Pretreatment

Before spraying silicone waterproofing agent, must ensure that the grass-roots surface clean, no dust, oil, moss and other pollutants. For dust and dirt, can use high-pressure water gun or water rinse, and use a clean cloth or mop to wipe. For stubborn stains such as oil stains, rust stains and moss spots, special cleaning agents should be used for cleaning, and the residual cleaning agents should be rinsed with water after cleaning.

2. crack and hole repair

The basic leakage problem is mainly divided into two categories: capillary water absorption leakage and cracks and hole water seepage. Silicone waterproofing agent is excellent in dealing with capillary water absorption and leakage, but for larger cracks and holes, spraying silicone waterproofing agent alone may not completely solve the problem. Therefore, before applying the silicone waterproofing agent, the cracks and holes should be repaired with a suitable embedded filling material. The repair material should have good adhesion and durability to ensure that the repaired base can withstand a certain water pressure and wind pressure.

3. silicone waterproofing agent spraying construction

Construction preparation: before construction, should ensure that the construction environment temperature and humidity is appropriate, and in accordance with the use of silicone waterproofing agent ratio for deployment. At the same time, construction personnel shall wear labor protection articles to ensure construction safety.
Spraying operation: Use professional spraying equipment or brush to evenly spray silicone waterproofing agent on the surface of the base layer. Spraying should follow the principle of first up and then down, first difficult and then easy, to ensure that every corner and gap can be fully covered.
Construction inspection: After the spraying is completed, the construction area should be inspected in time to ensure that the silicone waterproofing agent has been evenly covered on the surface of the base layer, and there is no leakage or uneven coating.
Conservation and protection: Before the silicone waterproofing agent is dried and cured, the construction area should be protected from rain or other pollutants. At the same time, after the silicone waterproofing agent is completely dried and cured, necessary maintenance and protection work should be carried out to extend its service life.
Through the standard operation of the above steps, it can be ensured that the silicone waterproofing agent exerts the best waterproof performance during the construction process, and provides a strong guarantee for the waterproof protection of the building. At the same time, it is also necessary to pay attention to the safety and environmental protection issues during the construction process to ensure the health and safety of construction personnel and the surrounding environment.
