Matters needing attention in Taizhou waterproof decoration
The first step: when doing waterproof construction, we must first do a good job of grass-roots treatment. Remove the original decorative materials, clean up the eluvial soil and cement, and require the surface to be flat and dry.
Step 2: Spread waterproof coating. Brush a layer of modified asphalt on the waterproof base, spread a layer of glass fiber cloth, brush it again, and finally brush paint on the second layer of glass fiber cloth to finish the waterproof treatment. Waterproof coating should be painted evenly, glass fiber cloth and waterproof layer should be closely combined, and there should be no brush leakage, bulging and falling off, otherwise the waterproof effect will be affected. If polyurethane is chosen as waterproof coating, it is generally unnecessary to add glass fiber cloth, and it can be brushed for 2-3 times repeatedly. Because the polyurethane coating itself can form an elastic protective film, it has certain tensile properties. In order to improve the waterproof effect, a layer of glass fiber cloth can be laid, but the cost will increase.
It should be noted that when the ground is waterproof, waterproof coating and glass fiber cloth should be laid on the wall 20-30cm away from the ground to prevent leakage at the joint between the wall and the ground, and form a closed and firm overall waterproof layer. For shower wall, soft wall and indoor wall that are afraid of leakage, waterproof coating should be painted at 1.8 meters or all the walls to prevent wall leakage.
Step 3: Do the "water resistance" test, which is an important means to test the indoor waterproof quality. After the waterproof project is completed, seal the door and drain, and fill the room with water to a certain level. If the liquid level does not drop significantly within 24 hours, it is qualified. ? After the "water retaining" test is completed, cement mortar protective layer should be made on the waterproof coating, and care should be taken not to destroy the waterproof coating. After the cement mortar protective layer is dry, it can be decorated normally by laying wall bricks or painting.
Common sense of waterproof decoration materials in Taizhou:
1. environmental protection one-component polyurethane
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. ? Strong adhesion to the base surface, high molecular substances in the coating film can penetrate into the fine cracks on the base surface, and the follow-up performance is strong. ? The coating has good flexibility, strong adaptability to base expansion or cracking, and high tensile strength. The waterproof effect is the best, but the price is also higher, the cost is higher, the drying and curing are slow, and it is rarely used in decoration companies! There must be professional construction!
Two. Acrylate waterproof coating
Acrylate waterproof material is made of pure acrylate polymer or pure propionate emulsion as raw materials, and a proper amount of high-quality fillers and additives are added, which belongs to one-component waterproof coating of synthetic resin. It is a water-soluble coating that can be diluted with water. After conjunctiva, it has great elasticity and ductility, remarkable waterproof effect and moderate price. It is the first choice for home decoration, but it is only used by some large decoration companies. In contrast, it is still high!
3.JS composite waterproof material
JS compliant waterproof material is a new waterproof material developed after absorbing foreign advanced technology. It is a waterproof coating composed of organic liquid and inorganic powder, which has the advantages of high elasticity of organic materials and good durability of inorganic materials.
Four. cement mortar
Low price? Convenient construction? The waterproof effect is not bad, and it is widely used by owners and decoration companies! Mortar waterproof coating is a two-component water-based waterproof mortar, which consists of organic emulsion composed of acrylate emulsion and various additives, and inorganic powder composed of special cement and various fillers in a certain proportion. This kind of paint is non-toxic, harmless and pollution-free, and it is a real environmental protection paint. It can be directly coated on the concrete surface, with firm bonding, convenient construction, fast drying and short setting time, and the ceramic tile can be pasted on the surface after 2 hours of construction. However, because this kind of material belongs to rigid waterproof coating, it lacks elasticity after film formation, which will affect the waterproof effect due to building settlement and dislocation, and is generally suitable for parts with relatively stable structure.
Verb (abbreviation of verb) circle
At present, there are decoration companies in use! Advantages are low price and good waterproof effect! Most of the waterproof coatings on the market belong to water-soluble materials, and all businesses also claim that water-soluble waterproof coatings are environmentally friendly materials, while most of them say that oil-soluble waterproof coatings are not environmentally friendly. In fact, no matter whether it is water-soluble or oil-soluble waterproof coating, as long as it has passed the relevant national environmental protection certification, such as China's environmental label certification or CTC product environmental protection quality certification, these materials are environmentally friendly and reliable.
