When selecting putty powder, the following aspects can be considered:

1. Type selection: putty powder is mainly divided into interior wall putty and exterior wall putty. The interior wall putty has good environmental protection performance and is suitable for indoor use; The exterior wall putty needs to resist the sun and rain, with high strength but slightly poor environmental protection. It is recommended that the interior wall should not be used externally and the exterior wall should not be used internally.  br style="display: block; max width: 100%;"/>

2. Strength and water resistance: there are two types of interior wall putty powder. The bond strength of ordinary putty powder is more than 0.25MPa, and the bond strength of water-resistant putty powder is more than 0.5MPa. Ordinary putty powder dissolves and foams in water, and is easy to return to alkali, mold, crack and fall off; The water-resistant putty can still maintain high bonding strength after immersion, which is suitable for home decoration.

3. Environmental protection signs: select putty powder that meets environmental protection standards. Generally, the more environmental protection signs, the more reliable the quality. The inferior putty powder may be added with glue to ensure the construction strength, and contains harmful substances such as formaldehyde.

All HuiGao products have passed the eight environmental protection certifications in the world

1. Brands: select well-known brands of putty powder, such as nippon, Henkel Baide, Meichao, etc. these brands' product quality and environmental performance are more guaranteed. What

2. Use cost: consider purchase cost, labor cost and maintenance cost. Due to the insufficient strength of inferior putty powder, the later maintenance and renovation costs are high; Although the price of high-quality putty powder is high, it can save maintenance costs in the long run.

Construction precautions:

• Mixing proportion: mix according to the proportion of powder and water, generally 1:0.3-0.4kg, and then put it for a period of time after mixing evenly. What

• Base course treatment: the base course shall be solid, free of floating ash and dirt, and the moisture content shall be less than 5%. If the base course is smooth, interface treatment is required; The loose wall shall be removed and the interface shall be treated.

• Construction environment: appropriate temperature and humidity shall be maintained during construction to ensure that the putty powder can be fully dried and cured.

Through the comprehensive consideration of the above aspects, we can choose the putty powder suitable for our own needs to ensure the decoration quality and environmental protection performance.
