According to the type of wall, different types of putty powder need to be selected for different wall types. For example, exterior wall putty powder should be selected for exterior walls, and interior wall putty powder should be selected for interior walls. For walls in humid environments, water-resistant putty powder should be selected.
Check product quality: Choose a reliable putty powder product, and you can view the product's packaging, instructions, testing reports, etc. High quality putty powder products should have clear information such as production date, shelf life, and execution standards, and all indicators in the testing report should comply with national standards.
Considering environmental performance: When choosing putty powder, priority should be given to products with good environmental performance. You can choose putty powder with environmental certification marks, such as China Environmental Labeling Product Certification, Green Building Material Certification, etc.
Base treatment: Before using putty powder, it is necessary to treat the wall base. Clean the dust, oil stains, loose materials, etc. on the wall surface to ensure that the base layer of the wall is flat, dry, and firm.
Mixing evenly: Mix the putty powder with an appropriate amount of water according to the requirements of the product manual. After mixing evenly, let it stand for a period of time to allow the putty powder to fully mature.
Construction method: Choose the appropriate construction method based on the condition of the wall and construction requirements. When manually scraping, attention should be paid to ensuring even thickness to avoid uneven thickness. When mechanical spraying, attention should be paid to the pressure and spraying speed of the spray gun to ensure uniform coating.
Drying and polishing: After applying putty powder, it is necessary to wait for it to dry. The drying time depends on factors such as environmental temperature and humidity, and generally takes several days. After drying, use sandpaper to polish the wall surface to make it smoother and more even.
