(1) Base strength is too low, pulverization or peeling, resulting in surface putty empty hollow, or even peeling.
(2) Base wall surface is not cleaned, floating soil or other debris lead to water-resistant putty can not normally adhere.
(3) The improper maintenance of cement and demoulding of base course result in the decrease of adhesion on cement surface and the failure of normal adhesion of water-resistant putty.

Under what conditions are cracks prone to occur in water-resistant putty?

(1) The putty cracks during the curing period due to the excessive thickness of single scraping.
(2) Construction under high temperature environment.
(3) Construction in a dry and windy environment.
(4) Construction under low temperature environment.

What are the factors causing foaming of water-resistant putty?
