The construction skills of waterproof coating mainly include the following aspects:
Preparation:
Clean the surface: Before applying waterproof coating, you need to clean the surface to be coated to remove dirt, dust and debris. You can use clean water, detergent or high-pressure water gun for cleaning.
Repair damage: Check whether there are cracks or damage on the surface, and repair it if necessary. You can use filler, glue or cement slurry for repair.
Choose the right coating: Choose the right waterproof coating according to the material and purpose of the surface to be coated. Common types include acrylic, polyurethane, silicone, etc.
Applying skills:
Applying tools: Choose the right brushing tools according to the type of coating, such as brushes, rollers, spray guns, etc., and make sure the tools are clean.
Apply evenly: Apply the waterproof coating evenly on the surface to be waterproofed, making sure that the coating covers all corners and cracks. Pay attention to controlling the thickness of the coating to avoid being too thick or too thin.
Multi-layer application: It is usually necessary to apply multiple layers of waterproof coating to enhance the waterproof effect. After the previous layer of paint dries, apply the next layer.

Spraying method: Use a spray gun to spray liquid paint on the surface. The construction is convenient and labor-saving. The spraying surface is relatively uniform and flat, but it will cause material loss.
Rolling method: Use a roller-shaped roller brush with fluff to apply. It is suitable for large-area flat finishing. The operation is time-saving and labor-saving.
Maintenance:
Drying time: After applying the waterproof paint, it needs to be fully dried. According to the instructions of the paint, it usually takes several hours or even days.
Check for leaks: Regularly check the surface where the waterproof paint has been applied to observe whether there is any leak and repair it in time.
