Types of putty scraper
1. The horn scraper is made of buffalo horn, with a wide and thin bottom and a certain slope to improve elasticity. Slowly become narrower and thicker upwards, and the whole is smooth. When the head is in a circular arc shape, the thumb and the other four fingers are divided across the two sides of the scraper, and the scraper is sandwiched between the thumb and index finger. When inserting putty for filling holes, holes, and cracks, only 1-2 rounds are allowed. First scrape down, then up. The putty in the holes and holes is completely scraped. When scraping putty, use your thumb and four other fingers to hold the scraper with your thumb and four fingers, and use force to fill the putty over the surface of the batch. Don’t repeat it back and forth. Avoid hitting hard objects to damage the scraper. The horn scraper is easy to deform. Wipe it clean in time after use, and insert it into the crack of the board or press it under a heavy object to prevent it from deforming.
2. The steel scraper is made of 0.5-1mm thick spring steel plate. The large and small widths are 5-12cm, and the length is 8-10cm. Grind the upper edge into a circular arc shape on the grinding wheel. It should be ground into a narrow upper and lower width, with a certain slope at the upper and lower sides. The lower end is ground into a thin mouth with 2mm near the edge, such as a kitchen knife. It’s mouth-like, so putty is easy to shave.
3. The plastic scraper is made of multi-layer resin rubber sheet, such as phenolic resin sheet, and the size, shape and mouth are ground to be similar to steel scraper. Steel-skin scrapers and plastic scrapers are mostly used to apply large-area putty. Not only does it save effort, the putty is also solid.
4. The rubber scraper is usually made of 5-10mm thick solvent-attached and oil-resistant rubber block. The upper side is ground into an arc shape, and the lower side is ground into a thin mouth of I-2mm thickness. This kind of scraper is rich in elasticity, soft and hard, and is suitable for scraping arc-shaped and complex shapes. But it is not suitable for scraping putty on a large area. Because of its large elasticity, the putty will not be compacted, the scraped putty is relatively loose and it is not easy to scrape thin.
