What is the best waterproof material?

Lead: In the furniture decoration project, in order to prevent the infiltration of rain, snow and other substances, every household will buy waterproof materials for decoration. Waterproof materials can not only be waterproof and impervious, but also have the function of isolating air and toxic gases. Waterproof materials in the market have various properties, and different waterproof materials need to be selected for different use areas. So what is the best waterproof material? Bian Xiao's article today will give you a detailed introduction.

A, cement-based waterproof material

There are two kinds of cement-based waterproof materials in the market: universal waterproof materials and flexible waterproof materials.

Universal waterproof material is a two-component waterproof material consisting of liquid material composed of acrylic emulsion and additives and powder composed of special cement, graded sand and special mineral powder in a specific proportion.

Flexible waterproof material is a two-component, ductile plastic modified polymer cement-based waterproof slurry composed of acrylic emulsion, selected additives, cement, sand and rubber powder in proportion.

application area

1, indoor and outdoor cement concrete structures, mortar masonry walls and floors;

2. Bathroom, bathroom, kitchen, floor and balcony;

3. Used for priming treatment of stone, ceramic tile, wood floor, wallpaper and gypsum board before paving, which can prevent water and salt pollution.

Second, high elastic waterproof coating

High-elastic waterproof coating is a high-performance waterproof coating based on advanced acrylic emulsion and scientifically processed with various additives and fillers.

application area

Waterproof, seepage-proof and moisture-proof of roof, bathroom, basement, reservoir and wall.

Third, anti-corrosion and waterproof materials

It is suitable for waterproofing and anticorrosion of Shi Zhuan products such as marble, cultural stone, artificial stone, cut fake stone, ceramic tile, mosaic and tablet inscription.

Fourth, composite materials.

High-polymer high-weatherability waterproof composite material series is a flexible membrane material specially designed for crack prevention of building facilities. Because of its strong adhesion and good ductility, it can only be removed by mechanical means after being coated on cement, asphalt and other surfaces, which can adapt to harsh environment and climate and has a short service life 10 year under technical thickness.

application area

1, the movable part of the building facilities, and the old and new parts overlap.

2. Bonding and sealing of light steel workshop and residence with color steel plate

3. Metal roofs and grain depots

4, around the skylight, right-angle surface, dead angle

5, wall pipes, chimneys, vents

6. Bonding and sealing of light steel structure

7, basement, bathroom, bathroom, etc. Leak seal.

Five, polyurethane waterproof

Polyurethane waterproof coating is a one-component environment-friendly liquid building waterproof coating based on imported polyurethane prepolymer and without additives such as tar and asphalt. Curing after contact with moisture in the air, forming a firm and tough seamless integral waterproof film on the surface of the base. It can be directly constructed on various wet or dry foundations.

Six, wall waterproof

It is a polymer prepared by a unique formula, which not only has the characteristics of high bonding strength and good impermeability, but also does not affect the construction and installation of floor tiles, mosaics, wood floors and gypsum boards.

application area

1, indoor and outdoor concrete structures, precast concrete structures, cement plastering, brick walls and lightweight brick walls;

2. Before paving stone, ceramic tile, wood floor, wallpaper and gypsum board, apply it on the substrate for pretreatment to prevent water and salt pollution;

3 basements, stations, tunnels, civil air defense projects, mines and building foundations.

Seven, acrylic waterproof material

Acrylic resin, also known as acrylic resin waterproof and anticorrosive material, is environmentally friendly and non-toxic, and is a polymer waterproof and anticorrosive system modified by polymer molecules.

application area

Waterproofing, anticorrosion, seepage prevention, moistureproof and leakage repair works for industrial and civil buildings, internal and external walls, concrete, basements, pools, water towers, special-shaped roofs, tunnels, toilets and bathrooms, dams and other parts.

Once the waterproof work of the house is not done well, with the passage of time, the house will be gradually eroded by rain, civil drainage or groundwater, which will not only damage the quality of the house, but also affect its life. Choosing suitable materials is the key to waterproof engineering. The above small series introduces the relevant knowledge about waterproof materials in detail, including cement-based waterproof materials and high elastic waterproof coatings. , and their respective scope of application. I hope that small article can help everyone.
