Indoor Waterproof Paint

 Indoor waterproof coating is a functional coating material specially used in indoor waterproof projects. It can form a continuous and dense waterproof film on the surface of various substrates, effectively preventing water penetration and playing a waterproof and moisture-proof role. This type of coating is mainly used in indoor areas that need to be in contact with water for a long time or may be damp, such as bathrooms, kitchens, balconies, basements, etc. The floors and walls of these areas are often eroded by water and moisture in daily use. If the waterproof treatment is not in place, water seepage, dampness, mildew and other phenomena may occur, affecting the living environment and the service life of the building structure. Therefore, the selection of suitable indoor waterproof coatings and standardized construction are important links to ensure that the indoor space is dry and comfortable.

 Indoor waterproof coatings prevent moisture from penetrating into the substrate by forming a seamless and continuous waterproof protective film on the construction base. Its working principle is to use the density and water resistance of high molecular polymer materials to form a physical barrier after drying to block the invasion of moisture and water vapor. At the same time, high-quality waterproof coatings also have a certain degree of flexibility, which can adapt to the small deformations and cracks of the substrate caused by temperature changes or slight vibrations, thereby ensuring that the coating maintains a good waterproof effect for a long time.

1. Excellent waterproof performance By forming a continuous and dense waterproof film on the base surface, it effectively prevents water penetration and ensures a dry indoor environment. Even in a humid environment for a long time, it can maintain a good waterproof effect.

2. Good flexibility With excellent flexibility, it can adapt to slight deformation or cracking of the substrate and avoid damage to the waterproof layer caused by deformation of the base.

3. Strong bonding with a variety of substrates It is suitable for a variety of substrates such as concrete, masonry, metal, wood, etc., and can form a good bond with these materials to ensure that the waterproof layer is firmly bonded to the substrate and avoid delamination and bulging.

4. Simple construction Most of them are constructed by brushing, rolling or spraying, which is simple to operate and does not require complex tools and equipment. In addition, the tools are easy to clean after the construction of water-based waterproof coatings, which further improves the construction efficiency.

5. Good environmental performance Most of them are water-based environmentally friendly materials with low VOC content or almost no harmful substances. There is no odor after construction, which is friendly to human health and indoor environment, and is very suitable for home decoration.

6. Durability and anti-aging performance. It will not lose its waterproof effect due to moisture, temperature changes or aging during long-term use. It has a long service life and reduces the cost of later maintenance.

7. Alkali resistance and corrosion resistance. It has good alkali resistance and can effectively resist the damage of the alkaline components in the base cement mortar to the coating. In addition, it also has a certain degree of corrosion resistance and is suitable for areas such as kitchens that may be exposed to oil or chemicals.

Base treatment is the key to ensure the adhesion and waterproof effect of waterproof coatings. Before construction, dust, oil and loose materials on the base surface should be cleaned to ensure that the base surface is clean, flat and solid. For holes or cracks on the base surface, cement mortar or special repair materials should be used to repair them to avoid affecting the continuity of the coating. For base surfaces with strong water absorption (such as concrete or mortar base surfaces), they should be properly sprinkled with water before construction, but it is necessary to ensure that there is no clear water on the surface to avoid affecting the film-forming effect of waterproof coatings.

Apply multiple times to ensure the thickness of the coating. During the painting process, pay special attention to key parts such as corners, pipe roots, and yin and yang corners. These locations are prone to leakage. It is recommended to first carry out local reinforcement treatment, use additional layers or multiple brushing methods to ensure that there are no leaks and weak points.

Avoid long-term exposure to high temperature or humid environments, which may cause changes in the properties of the coating or expiration. Ensure that the paint container is well sealed during transportation to prevent leakage.

Avoid extreme low temperatures during transportation, and use insulation measures when necessary.

Water-based paint and solvent-based paint should be transported separately to avoid mixing to prevent chemical reactions after leakage.

Most of them are barreled or bagged products. They should be handled carefully during transportation to avoid falling, collision and severe vibration to prevent damage to the packaging and leakage.

Long-term direct sunlight will accelerate the aging of the paint, especially solvent-based paint may increase volatility due to temperature rise. Therefore, the paint should be stored in a cool place.

Solvent-based paint is flammable to a certain extent and should be kept away from fire sources and high temperature areas, and equipped with fire-fighting equipment.

The container of waterproof paint should be sealed in time after opening to avoid contact with air to reduce water volatilization or curing. Unopened paint should ensure that the container is intact.

Waterproof paint should be stored in a dry, cool place to avoid direct sunlight. The ideal storage temperature is usually between 5°C and 30°C, avoiding extreme environments of high and low temperatures.
