Metech MD-300 Wood Floor Sander

Cement Floor Grinding

1. Installing #24 diamond sandpaper allows you to smooth the mortar layer on cement floors, while dust is automatically drawn into a cloth bag, resulting in a uniformly textured yet slightly rough surface. This prepares the surface for easier penetration of applied putty, enhancing the adhesion and grip between the paint and the floor—making it less likely for the paint to peel or flake off.

2. The surface treated with putty may develop particles or bubbles. Switching to 80# or 100# sandpaper on the roller can effectively replace manual putty smoothing, delivering superior results—especially in projects involving self-leveling or epoxy resin flooring, where the final surface finish is further enhanced.

Plastic track and court grinding

1. Installing 24# fine sandpaper can smooth the recycled rubber granules on the composite plastic base, making the granules more firmly bonded and tightly packed. This results in a smooth, even surface with minimal roughness, enhancing the adhesion between the rubber and the particles.

2. If the old plastic track granules have already fallen off, use 24-grit sandpaper to sand and smooth the surface, creating a slightly rough texture. Then, reapply the plastic material, ensuring excellent adhesion.

Grinding to remove stains from hard surfaces

1. Attach 24# emery cloth to the grinding cylinder to remove residues such as gypsum and cement left on the floor due to construction or decoration.

2. It can effectively remove grime, old coatings from factories, warehouses, basketball courts, and various sports surfaces—such as oil stains and paint—leaving the ground clean and looking brand new, thus facilitating secondary floor renovations.
3. Use 24# emery paper to sand off rust from steel plates larger than 3 square meters, then use 100# emery paper for refinishing and polishing.
