Putty powder as the basis of decoration is indispensable, putty powder is not toxic green gas building materials, according to the different uses can be divided into: wall putty powder and interior wall putty powder, suitable for cement wall, gypsum board, composite board Such as a variety of wall construction, what is the external wall putty powder? External wall putty powder has strong adhesion, penetration and excellent water resistance. What is the difference between interior wall and exterior wall putty powder?
What is external wall putty powder
The external wall putty powder is based on inorganic binder materials, fine materials, and other additives. Its outstanding characteristics are high bond strength, water resistance, alkali resistance, and good construction performance. It can be used as an outdoor building surface leveling material once and for all. Cracking, blistering, pulverization and shedding are avoided.
How to use exterior wall putty powder
1, the grass-roots level should be solid, clean, roughly flat, no clear water, the strength of the grass-roots level should be greater than or close to the strength of putty.
2. The base layer with strong water absorption should be first treated with water or diluted Lanes interface treatment agent, and then puttying after wetting.
3, the new plastering cement wall should be putty after the curing period.
4, according to putty powder: water = 1:0.5 ratio stirring, standing for 10 to 20 minutes and then stir evenly to use.
5. Use a steel scraper or a spatula to scrape in the normal way. The number of strokes should not be excessive, and should be evenly formed. Do not leave traces of joints.
6, scraping thickness of 0.8 ~ 1.5mm, the amount of 1 ~ 1.5kg/m2, generally two times survival.
The difference between interior wall and exterior wall putty powder
First, the interior wall putty powder
1. Inner wall putty powder is made of high-performance polymer, methyl cellulose ether and other raw materials. It is a one-component interior wall special putty powder with good sturdiness, bonding strength and good waterproof capacity. It is suitable for Premium clubs, convention centers, and high-end venues that need to prevent the effects of external wall seepage.
2. Features: The wall surface of interior wall putty powder fiber can be washed with water, it can not be removed, it does not fall off, and it is not lightly impacted.
3. How to use: Put the putty powder in water for about 10 minutes and put it in a paste-like putty. Let it stand for 5 minutes and then scrape it on the wall. Usually scrape it twice. The second time it scrapes, it has to wait the first time. Can scrape. After drying, sandpaper should be used for grinding. After the leveling, the dust on the entire wall should be removed, and the latex paint can be applied after being dried.
4. Safety and stability: Non-toxic and chemically stable during normal or pyrolysis.
two. Putty powder for exterior walls
1. The external wall putty powder adopts imported high polymer polymer redispersible rubber powder, mixed with methyl cellulose ether, modified starch ether, anti-crack fiber as the weight ratio of putty powder mixture (3%), etc. The outdoor high-grade putty powder has strong resistance to micro-cracking of the wall, and has good properties such as good forehead viscosity, impermeability, reliability, and no self-shrinkage.
2. Characteristics: The putty powder produced by our factory has good crack resistance, which greatly saves the maintenance cost of the entire strong surface.
3. How to use: Apply external wall putty powder and stir it in water for 5 minutes. Then apply it on the wall. Generally the thickness should not exceed 2-3mm. According to different requirements, it can be divided into one to three batches to increase the thickness.
4. Note: Because the external wall putty powder has good water retention capacity, it can slow the solidification and avoid the early drying shrinkage cracks. Therefore, care should be taken during construction to ensure that the first layer is dry before the second layer can be used. The temperature of the construction environment must not be less than 5 degrees. It cannot be constructed on rainy days.
Editor's summary: The relevant information about what is the difference between the exterior putty powder, interior wall and exterior wall putty powder is introduced here for everyone.
