How to make putty powder waterproof?In the renovation process, waterproofing works have always been a top priority. As a common material for wall treatment, putty powder is directly related to the decoration effect and service life of its waterproof performance. So, how does putty powder do waterproof?Let's follow Meien to find out.
First, putty powder waterproof principle.
In order to understand how putty powder is waterproof, we must first understand its waterproof principle. Putty powder is a kind of powdered building materials with cement, gypsum and other main raw materials, which has good adhesion and crack resistance. In the construction process, by adding a special waterproofing agent, the putty powder has excellent waterproof performance.
There are two main types of this kind of waterproofing agent: one is polyvinyl alcohol (PVA) waterproofing agent, which can improve the adhesion of putty powder and form a dense protective film to effectively prevent moisture penetration;The other is an acrylic waterproofing agent, which improves its impermeability by changing the microstructure of putty powder.
Second, putty powder waterproof construction skills.
1.Preparation: Before construction, the substrate should first be treated to ensure that the surface is clean and flat, free of loose particles and oil stains. For the base layer of the wall, a layer of interface agent can be applied by brushing or spraying to improve the adhesion of the base layer.
2.Ingredients: According to the needs of the project, the putty powder, waterproofing agent and water are mixed in a certain proportion. During the mixing process, it should be fully stirred to ensure that the waterproofing agent is evenly distributed.
3.Construction: The prepared putty powder is applied to the surface of the base layer, and the thickness is adjusted according to the actual needs. The surface of the coating should be smooth and smooth to avoid defects such as bubbles and sand holes. During the application process, a thin application can be applied multiple times to improve the waterproof effect.
4.Maintenance: After the construction is completed, proper maintenance should be carried out. Under normal circumstances, the putty powder waterproof layer needs to be kept moist after construction to facilitate the penetration and crystallization of the waterproofing agent. During the curing period, avoid damage to the waterproof layer by impact, friction and so on.
5.Acceptance: After the expiration of the curing period of the waterproof layer, the waterproof test will be carried out. Water splashing, spraying and other methods can be used to test the waterproof effect. If there is no leakage, it means that the waterproof construction is successful.
3. Precautions for waterproofing putty powder.
1.Choose high-quality putty powder: There are many brands of putty powder on the market, and the quality is uneven. When purchasing, you should pay attention to the production date, shelf life, brand reputation and other factors of the product to ensure that you can purchase high-quality products.
2.The addition of waterproofing agent: The amount of waterproofing agent should be adjusted according to the actual demand, excessive addition may cause the waterproof layer to be too greasy and affect the adhesion of the coating.
3.Construction environment: During the construction process, the environment should be kept clean and well ventilated to avoid pollutants such as dust affecting the waterproof effect.
4.Avoid damage to the waterproof layer: After the construction of the waterproof layer is completed, attention should be paid to protection to avoid damage such as impact and wear in a short period of time.
In short, putty powder waterproofing is an important part of home waterproofing. By understanding the principle, construction skills and precautions of putty powder waterproofing, we can better ensure the comfort and safety of the home environment. As long as you grasp these points, even in a humid and watery environment, putty powder can exert excellent waterproof properties. To make home life better, start with doing putty powder waterproofing.
