The newly renovated living room did not last long, and the wall was peeled, powdered, and peeled off. Of course, it was annoying to encounter such problems. In fact, the root cause of this problem is not the level of coating and construction level, but the treatment of the base layer during construction.
Putty is best to welcome the old
How can we avoid these problems? First, the wall must be firm, firm, dry, with a moisture content of less than 10%, and the old base must be cleaned. Some developers use the 821 putty when handing over the house. This putty is easy to be powdered, peeled, and peeled off. It must be shoveled off and re-processed. Second, the primer must be applied once before re-scraping the putty. The primer can improve the pH of the base wall, increase the strength of the base layer, and make the coating have better adhesion to the base layer. When choosing the primer, you must choose a special primer for the regular manufacturer. Do not use some glue instead.
Finally, and the most important step is to put the putty. Before applying the latex paint, you need to scrape the putty twice. Should choose the water-resistant putty of well-known enterprises, these putty have high whiteness, good water resistance, high bonding strength, no skin, no powdering, no falling off after use. After treatment, the wall surface is coated with qualified latex paint. Your wall will have no worries.
Whether it is “standard paintâ€, “environmental paint†or “green paintâ€, it must first meet the national standards for hazardous substances. It should be said that standards-compliant paints are safe. Although the VOC in the paint is harmful to the human body, it has a problem of quantity. As long as the VOC is within the limited range, it is not enough to cause too much damage to the human body, and the consumer does not have to talk about the toxic color change.
Paint picks like this
Like other products, the coatings market is also mixed. Mr. Anju reminds everyone that when buying paint, don't be cheap, you must choose a well-known brand of products, so as to ensure the safety of yourself and your family.
Do not be superstitious about the word "green" on the coating package. You should carefully check the quality inspection report of the product; observe whether there is rust or leakage at the joint of the iron drum; pay attention to whether the clear mark on the iron barrel is complete. For imported coatings, it is best to choose a product with a Chinese logo and description.
Due to excessive levels of harmful substances such as VOC and formaldehyde, most of them have pungent odor, which makes people sick and dizzy. Therefore, if consumers smell a pungent smell when purchasing, they need to choose carefully. In addition, it is best not to buy a fragrance-added coating because the additive itself is a chemical product.
Save the purchase invoice. If possible, ask the seller to open the paint bucket and check it out. If there is a serious stratification phenomenon, it indicates that the quality is poor; with the stick gently stirring, after lifting, the paint stays on the stick for a long time and covers evenly, indicating that the quality is good; It is very difficult to wash off the clean water; the lighter the hand, the finer the better.
