1. Classification of scrapers: According to data, scrapers can be divided into metal scrapers, rubber scrapers, bamboo scrapers, horn scrapers and plastic scrapers. According to function, the scraper can be divided into flat knife, trowel knife and scraper separated from each other. In the construction of putty and mortar layers of floor paint, the metal flat knife is most commonly used, while the metal trowel knife is most often used in the construction of self-flow floor paint.
2. How to use the scraper: The scraping can be stopped until the paint is prepared and stirred. When scraping, press the scraper forcefully. The edge of the scraper is close to the air so that the scraper or flat knife tilts to a certain angle and scrapes along the air. When applying putty or medium paint, scrape repeatedly from left to right, but pay attention to the leveling of the lap with knife. If the left and right forces are uneven or the blade tips are not exerted properly, it is easy to produce joints or stripes.
