A scraper is a lot like a piece of sheet metal. The difference is that a scraper is designed specifically for a purpose. Therefore, it is common for paint scrapers to lose their sharpness after a few months of continuous usage. Blunt scrapers do a terrible job of cleaning the paint. So, you need to sharpen it wherever it goes. The easiest way to sharpen a scraper is using sandpaper and a fine file. Take the file and run it over the edge of the blade a few times. You can use the sandpaper to smoothen the blades.If you are looking to buy paint scrapers online in the UAE, look no further as you are in the right place.
