At present, the toilet waterproof materials on the market mainly include polymer cement-based waterproof materials, polyurethane waterproof materials and SBS modified asphalt waterproof materials, etc., the main brands are desert Oasis, Metushi, Fuya, Duluth, Carbori and so on. So many different materials and brands are really dazzled by the owners, in the end which kind of bathroom waterproof material is good? The advice of the decoration industry is to know more about the advantages and disadvantages of each brand of each material, and the owners should try to avoid the disadvantages and make use of the advantages when choosing toilet waterproof materials.
Waterproof coating is a thin film, which is coated with paint on the building and formed by chemical reaction. Through this film, the surface of the building is isolated from the water, thus playing a waterproof role. At present, there are generally two kinds of waterproof coatings on the market, one is polyurethane waterproof coating, and the other is polymer cement-based waterproof coating.
The biggest feature of waterproof coating is good waterproof performance. High temperature resistance, low temperature resistance, high temperature up to 170 degrees Celsius, low temperature to -20 degrees Celsius will not break; The adhesion of this coating is very strong, whether it is for glass or ceramics, plastics and other materials, it can be a good bond. It will not be layered under the action of external force, and the adhesion is strong, which can form an overall waterproof system. In addition, waterproof coating is also an environmentally friendly coating, non-toxic, tasteless. It will not have a bad effect on people’s health.
Bathroom waterproof material which is good
1, polyurethane waterproof coating: polyurethane waterproof coating is the most common class of waterproof coating on the market, it is made of isocyanate, polyether and other by addition polymerization reaction containing isocyanate prepolymer, with various additives mixed processing made of single-component polyurethane waterproof coating. There are several common types of paint.
2, non-tar polyurethane waterproof coating: the waterproof coating is a two-component material, the use of water as chain extender, to avoid the toxicity of amine chain extender, the formation of elastic seamless rubber waterproof layer after curing.
3, acrylic waterproof coating: the waterproof coating with pure acrylic copolymer or pure propionate emulsion, adding an appropriate amount of high-quality filler, auxiliary configuration, is a synthetic resin class single-component waterproof coating.
How to waterproof the bathroom:
1, hydropower transformation need to pay attention to waterproof layer: Many decoration owners in the water and electricity transformation, will transform the pattern of the bathroom and the upstream and downstream pipelines, so consumers in the supervision of the construction, must be stressed to the decoration workers can not destroy the original waterproof layer, if accidentally destroyed the original waterproof layer, you must be repaired in time, and even redo the waterproof project, to ensure that there will be no leakage.
2, the purchase of the correct waterproof material, recommended single-component environmentally friendly polyurethane coating, mainly because this coating can tightly wrap the pipeline and the ground, penetrate the gap, will not shrink after drying, than waterproof cement and other rigid materials are more suitable for the bathroom this pipeline, more gaps in the small area of the house. The material cost per square meter of this paint is about 50 to 60 yuan, which is the price that the general decoration owners can afford
3, rainy days do not paint operation: in order to have a good waterproof effect, waterproof paint must be painted three times, the drying period of single-component environmentally friendly polyurethane paint is about 3 to 4 days, if the waterproof material is painted in rainy days, the effect of waterproof paint will not be very good.
4, to do a good job of ground waterproof work: before paving the floor tiles, we must do a good job of waterproof engineering; After the tile is laid, it is necessary to ensure that the tile surface has a drainage slope (generally about 1% is appropriate), and the slope is toward the floor drain, which is conducive to wastewater discharge.
5, do a good job of wall waterproof work: the bathroom bath will splash water to the adjacent wall, such as no waterproof layer protection, the next wall and opposite corner wall is easy to damp and mildew. Therefore, it is necessary to do a good job of wall waterproof before laying wall tiles, general waterproof treatment of the wall to do 30 cm high waterproof treatment, but non-load-bearing light body wall, it is necessary to make the whole wall waterproof, at least 1.8 meters high.
6, finally finish the work to do waterproof inspection: after the completion of the waterproof project, for the sake of insurance, or to do waterproof inspection, if the waterproof inspection is not qualified, must not make do, to let the construction team redo the waterproof project, if conditions, you can ask professional decorators to help supervise the waterproof project.
