Mark by scraping is a job that involves using a tool to scrape off excess material from a surface. This is usually done to create a smooth, even surface or to remove any imperfections. The term SCUFF is an acronym for 'Scrape Clean Up Finish and Flatten'. This job requires the use of a scraper to remove any excess material from the surface, followed by cleaning up the surface with a cloth or brush, finishing it with a sealant or paint, and flattening it with a sanding block.
