First, the purchase skills of putty powder
1, putty powder is suitable for cement mortar plastering, mixed mortar plastering, concrete, gypsum board, decorative mortar, clay brick and other new and old wall bases, which is waterproof and breathable. It should be used in decoration engineering together with building interior wall coating.
2. Ordinary putty is used where waterproof is not needed, and waterproof putty is used where waterproof strength is required. Therefore, Bian Xiao suggested that you buy waterproof putty powder.
3, waterproof putty rubber powder is suitable for all indoor walls, basements and bathrooms and other wet engineering parts and residential waterproof walls scraping putty. Not suitable for the surfaces of soft materials such as metal products, paper products, fabrics and polystyrene.
4. The interior wall is made of waterproof putty powder, and the kitchen and bathroom are close to the interior wall. When the project is in a humid environment, such as basement and toilet, class II products should be preferred.
5. Volatile organic compounds (VOC) value.
Second, the advantages of putty rubber powder
1, good environmental protection.
The proportion of putty in the cost of home improvement can be ignored, but its construction area accounts for more than 80c/o of the total area of home improvement. If environmental protection is not sufficient, the toxic substances contained in it will be released indoors for a long time, which will endanger the health of residents. Early putty was made of toxic glue such as107,801,talcum powder and white cement. Because it contains a lot of formaldehyde, it cannot be used. Some putty glue is labeled as "environmentally friendly putty glue", but there are actually three products. When choosing putty, try to use environmentally friendly, safe and environmentally friendly putty powder produced by large enterprises, which should be paid special attention to.
2. Bonding strength
At present, some users still use the original method to prepare putty. The putty prepared by this method is inaccurate, inaccurate in measurement, poor in adhesion and easy to peel or fall off. In addition, the common inferior putty powder on the market usually has no quality guarantee.
3, smooth and delicate
Some tiny sand marks will be formed after putty is polished, which is beneficial to the adhesion of latex paint. However, if the sand mark is too thick, the latex primer is difficult to fill and cover, which will affect the smoothness of the coating surface.
4. Good water resistance
Waterproofing is usually an important index to determine the quality of putty. Waterproof putty not only has good adhesion under moldy conditions, but also is very helpful for the formation of surface film.
5. Architecture
Good putty construction is easy to scratch, sand and crack. Construction is also the basic guarantee of construction results.
That's all that Bian Xiao introduced to you.
