How to use putty powder, putty powder use method and matters needing attention
1, the base should be solid, clean, roughly smooth, no clear water, the strength of the base should be greater than or close to the strength of putty.
2. The base course with strong water absorption should be moistened with water or sprayed with glue for sealing treatment before blowing putty (consistency should be suitable for construction).
3, new plastered cement wall should be in the maintenance period after scraping putty.
4. Stir evenly according to the proportion of putty powder: water = 1:0.5, let it stand for 10 ~ 20 minutes and stir evenly again before use.

Matters needing attention when using putty powder:
1. Keep it waterproof and moisture-proof. The storage period is six months.
2. The construction temperature is above 0℃. Putty powder should be used within 4-5 hours after it is adjusted into a paste to avoid prolonged deterioration.
3. Putty powder shall not be used on the same construction surface with other putty to avoid chemical reaction and chromatic aberration
