High rise building external wall plastering project: during the plastering construction of a high-rise building external wall, a brand of environmental friendly defoamer was used, which effectively eliminated foam in the mixing process, improved the flatness and compactness of the plastering layer, and reduced hollowing and cracking

The quality issues such as seams have received unanimous praise from both the owner and the construction party.

Through comparative experiments and on-site testing, it was found that the use of defoamers significantly improved the fluidity and workability of cement mortar, increased construction efficiency by about 20%, and reduced the incidence of quality problems in the plaster layer by more than 80%. This indicates that the application effect of

cement mortar defoamer is significant in this project and has high promotion value.
