Using a floor scraper as part of the tile installation process ensures a smoother, safer, and more efficient workflow, ultimately leading to a better end result. M-D's Heavy Duty Floor Scraper features a 7 in. high carbon steel blade used to prep floors for tile installation. It's crucial to ensure the surface is clean, flat, and free of any debris or old adhesive when installing new tiles. This will ensure a smooth base for the new tiles. The long handle provides leverage to ensure the subfloor is properly prepped. By effectively removing old flooring materials, floor scrapers help to eliminate potential hazards, such as loose tiles or adhesive residues, which could cause accidents or injuries during the installation process or afterward.
