Are you facing those problems of wall putty?

Drying quickly

1.Due to the high temperature in summer, the water evaporates quickly during the operation of scraping wall putty, which usually occurs on the second stage of the construction.

2.Cellulose ether’s water retention is poor, qualified cellulose ether should own the capacity of keeping mortar at least two hours before scrapping.

During construction, the temperature should not be higher than 35℃. The second stage of wall putty should not be scraped too thin.
If there is a quick-drying phenomenon, it’s need to check and identify whether it’s caused by the formula.
If quick-drying happens, it is recommended that the construction should be completed for about 2 hours after the previous construction when the surface is dry, this way helps reduce the quick-drying.
Choose high quality cellulose ether with good performance of water retention and workability even in summer extreme weather.


Hard to polish

1. It is more difficult to polish a wall when it’s too solid or polished during construction, which with increased density and stronger hardness of the wall putty layer.

2 The slow-drying wall putty will achieve the best hardness after one month. If it encounters water, such as wet weather, rainy season, wall seepage, etc., it will accelerate hardening and make it more difficult to polish, and the polished layer is rougher.

3 Different formulas of wall putty are mixed together, or the dosage of formula is adjusted incorrectly, so that the hardness of the wall putty after scraping is higher.

If the wall is too solid and hard to polish, it should be roughed with 150# sandpaper first and then 400# sandpaper to modify the pattern or scrape two more times before polishing.
Choose high quality cellulose ether in middle viscosity, with highly recommend for wall putty.

Off powder


1. External factors including thermal expansion and contraction, earthquakes, subsidence of foundations.
2. Incorrect proportion of mortar in the curtain wall will shrink and cause cracking drying.
3. The calcium ash was not sufficiently oxidized.

External forces are uncontrollable, it is difficult to prevent and control.
The scraping process should be carried out after the wall drying fully.
