Putty powder has been widely used in recent years. The main varieties, composition and characteristics of this putty powder are shown in Table 4-42. From Table 4 and 42, we can see that the varieties of putty powder are very complete, such as ordinary type of putty, external wall putty, water-resistant type of putty, external wall putty and high bonding strength putty used on the surface of old ceramic tile, etc. The properties of these putties can meet the quality requirements of relevant national or industrial standards and compulsory national standards GB18582-2001 "Limitation of harmful substances in interior wall coatings for interior decorative materials". Importantly, because of their good physical and mechanical properties, environmental protection performance and construction (scraping) performance, these products have been widely used and become an important supporting material for indoor and outdoor decoration and decoration.
