Sanding and Polishing Floors – How We Do It

Sanding and polishing floors usually involves three stages: Preparation, sanding, and coating with a protective sealant. Professionally sanded floors can add thousands of dollars to the value of your house and can enhance the look of a modern or older style home. So if you live in Brisbane and think your wooden floors could do with some sanding and polishing, give us a call today!


Preparation is the first stage of the sanding process. All nails are punched down. Nails can severely damage the sanding machines which are being used. 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.


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. Any unevenness in the boards is 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 followed by 36-grit. The areas around the perimeter which cannot be reached by the large sanders are sanded using an edging machine. 60 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. Filling of holes or boards is required at this stage of the floor sanding process followed by fine edge sanding. The same large belt sanding process follows using 100-grit. A rotary machine sander is then used to create the final finish. The grit papers used for this process are 100 & 120-grit.

Floor Polishing

The sanded floor is vacuumed and then coated with solvent-based polyurethane or other sealants, such as water-based products or oil. Three coats are applied of each coating material.
