The use of waterproof material in the home decoration process is indispensable, and some regular use places such as kitchens, balconies, bathrooms, etc., need to use waterproof materials for waterproof treatment. For most owners, decoration is also the first time. Little knowledge of building materials knowledge, such as common home improvement waterproof material which classification? Another example is how to buy waterproof material? If you are still confused, don't worry, look down.
Waterproof material which waterproof material classification
Home-improvement waterproofing is a “hidden project†in decoration. To achieve high-quality waterproof quality, picking a good waterproof coating is a crucial step. Nowadays, waterproof material brands on the market are mixed, and a variety of waterproof coatings make the owners do not know what to do. Home improvement waterproof materials can be roughly divided into the following five categories:
1, flexible mortar
Emulsion and mortar ratio is 5:4, with elasticity, even if the base layer deformation cracking will not affect the waterproof effect. It is mostly used on the surface of water, such as wall surface and ground surface, but it cannot be used on the back surface of the top surface. If waterproof is not done well, there is water penetration and it is easy to make water seepage.
2, hard mortar (rigid mortar)
The ratio of emulsion to mortar is 1:4. After the brushing, the coating is not required and can be directly tiled, which is more convenient. After curing, it forms a cement block and does not cause water seepage. Its back surface has good waterproof effect and is its biggest advantage. The disadvantage is that this kind of mortar has high hardness and is easy to crack with the deformation of the base layer, so it is generally used for waterproofing the back surface.
3, polyurethane
Indoor and outdoor use, brushing is very thick, about 3 mm or so, and the elastic tension of more than 300%, very elastic, cracking of any substrate will not make it crack, the best waterproof effect. Although the safety performance control is among the environmental protection requirements, the odor of such a waterproof coating is relatively large, which is unacceptable to most people, and the environmental performance of a very few waterproof brands is not up to the standard. Polyurethanes are colloidal and are very thick. The use of scrapers during construction is laborious and complicated.
4, acrylic
Acrylic pure liquid, ready to use. Water-based, can be melted in water, it is easy to combine with the gap in the ground to form a strong waterproof layer, waterproof effect is better than flexible mortar. Due to its excellent waterproofing effect, flexible mortars and acrylates are more suitable for long-term immersion in water. The earliest and largest application of acrylic acid was in environmentally friendly paints and coatings.
The biggest feature of this kind of material is that it can be diluted with water to be a water-soluble material, and it is colorless and odorless (paints can be formulated with various colors as needed), but after the conjunctiva is indeed an extremely dense waterproof material. Therefore, the current paint basically does not have the same kind of paint smell (previously it was formulated with gasoline or thinner material). This material has considerable elasticity and ductility after the conjunctiva determines that he will not break with the settlement and dislocation of the substrate.
5, coil type
Most of the waterproof coatings on the market are water-soluble materials. Whether it is water-soluble or oil-soluble waterproof coating, as long as the relevant national environmental protection certification, such as China Environmental Labeling Certification or CTC product environmental protection, quality certification, etc., these materials are environmentally friendly and reliable.
Waterproof material purchase
Understand the classification of finished home waterproof material, the following Xiaobian and everyone to explain how to buy home waterproof coating>>
1, see the packaging
When choosing waterproof materials for home decoration, you should first look at the packaging. Whether the color of the product packaging is bright, whether the writing is clear, and whether the product name, net weight, manufacturer, and certificate are all complete. The real environmental protection waterproof material shall have the test report, product test report and product certificate issued by the nationally recognized testing center (CMA). Most of the well-known brands will have their own anti-counterfeiting labels. Pay special attention when purchasing.
2, see the texture
Home-installed waterproof material with or without precipitation, delamination and agglomeration. If there is any one of them, please do not purchase. These are all unqualified products and cannot be used after buying them.
3, smell the smell
There is no strong pungent odor in home waterproof material. Because waterproofing is tiling, how to use poisonous materials, there will be a long-term release of toxic gas in the home; re-replacement will be more troublesome, so we must pay special attention to it.
4, whether to facilitate the construction
There is a saying in the industry: "Three points of material, seven points of construction." The selection of materials is very important. We must choose materials suitable for home waterproofing. The specific performance is better waterproof performance, construction should be simple and convenient, environmental protection and non-toxic do not affect human health and so on.
5, look at the brand
Home waterproof material must meet the above requirements. However, there are many manufacturers that produce waterproof materials. Therefore, brand products should be purchased as much as possible. Because the quality of the brand products is good and stable, and the level of anti-counterfeiting is high, generally there are anti-counterfeiting queries and the risk of buying fake and shoddy products is avoided.
Home waterproof 4 big mistakes
1. Waterproofing on the wall is only for the areas where the water can contact. From the construction practice, this is wrong.
A. The glazed surface of your brick wall will be immersed in water.
B. Gutter groove must have waterproof function.
2, the wall of the water, usually shuttle, will soon be down, at the same time because the wall does not do waterproof will tiling after the cement mortar to close the water situation. Easy to bring problems such as emptying. (No matter what you do, this question always has to be considered)
3, a lot of people do only pay attention to the original cement wall and the surface of the water surface when facing the water, and ignore the back of the water surface protection, such as cabinetry and door cover back, it is best to do a waterproof seal, this way It is better to avoid leakage due to the water proof on the water surface, and the water penetrating into the back surface will cause the board to become moldy and rot.
4, waterproof also pay attention to the place: Bay window, balcony sealing problem, the problem of sealing around the vegetable dish, hand-washing table surface by the wall sealing problems, these are easy to ignore but not very important, but it is important About the cabinet door is not good, it turned out that the glass glue did not play well, causing the wood to rot.
Tips: Several points of construction waterproofing
1, strictly in accordance with the norms of construction, horizontal and vertical brush coating or coating 3-4 times, corner interface must be lapped tightly, carefully check, handle the trachoma, to avoid the omission;
2, do not forget to do a good job of conservation work after waterproof, in order to ensure the best waterproof effect;
3. After the construction is completed, perform the acceptance work: water storage test.
Concluding remarks: Everyone must purchase a waterproof material in the reputable building material market, and choose a qualified company for construction. Once there is a problem of water leakage, this will seriously affect the quality of our home life, and we must not ignore the water treatment. What about waterproof material waterproof material classification method and buy small series to introduce here, I hope this is useful to you.
