When sanding a floor, you'll need a few materials and tools to get the job done: 1. Floor Sander: This is a big machine used to sand the floor. It comes in different types, such as drum sanders or orbital sanders. 2. Sandpaper: You'll use sandpaper to sand the floor. It comes in different roughness levels, from coarse to fine. Coarser sandpaper is used at the beginning to remove old finishes or uneven surfaces, while finer sandpaper is used for a smoother finish. 3. Dust Containment System: Sanding creates a lot of dust, so a dust containment system is used to keep the area clean. It typically includes a vacuum or dust collection system attached to the sander. 4. Filler: You may need wood filler to fill in gaps or cracks in the floor before sanding. It helps create a smooth surface. 5. Finishes: After sanding, you can apply finishes to protect and enhance the floor's appearance. Common finishes include polyurethane, varnish, or oil-based and water-based finishes. 6. Applicators: To apply the finishes, you'll need brushes, rollers, or pads, depending on the type of finish you're using. Remember, floor sanding can be tricky, so it's often best to hire a professional who knows how to use these materials and tools properly.
