Sanding and polishing floors usually involves three stages: Preparation, sanding, and coating with a protective sealant.

Sanding preparation

Staples, tacks, and any nails need to be removed to prevent damage to the sander. Glue which has been used to secure coverings may need to be removed. Some glues clog the papers and running gear of the machines used, but can generally be sanded back to bare timber.

Sanding process

After the floor is prepared, the sanding begins. The first cut is done with coarse-grit papers to remove old coatings and to make the floor flat. The unevenness in the boards are removed. The most common paper used for the first cut is 36-grit, but for glue and very uneven floors we may need to start with 24-grit. The areas which cannot be reached by the large sanders are sanded by an edger, usually with an 80-grit disc. If filling of holes or boards is desired this is the stage where this is usually done. This may also be done after the first coat. 80-grit papers are usually used for the second cut with the large belt sander. The belt sander is used inline with the grain of the timber in this cut. An orbital finishing machine is then used to create the final finish. The grit paper used is 80-grit as the orbital is not as aggressive.
