Floor Sanding and Polishing

Watching Humidity Levels

Floor Sanding and Polishing

Timber floors may be re-sanded to restore the original finish or remove damage. The original finish may be compromised because of regular wear and tear. Or their may be more serious damage from water flooding, moisture in the air, or perhaps from heavy impacts.

Moisture in the air is one insidious way that floors can be damaged over time. Timber Flooring is a natural, organic material. It naturally has a certain water content. If this natural water content is increased or decreased, perhaps because of the surrounding environment, the timber will change shape.

An individual timber board that is exposed to high moisture will expand, warp, bend and generally change shape. A floor is comprised of many individuals boards pressed against eachother. If the individual boards change shape they push against eachother and cause further changes in shape This leaves us with an uneven floor that has protruding edges, not ideal to walk on.

It is best to prevent this type of moisture damage to floors. We can use a hygrometer to monitor the humidity of the indoor air. Ideally is should be between 35% and 55% humidity. 

If the indoor humidity is to high we can use air conditioning or a dehumidifier to lower the water content of the air.

If the indoor humidity is too low, cause the floorboards to dry out, we can add water to the air with a humidifier or with some houseplants. 

If the floor is damaged it can be re-sanded to restore a smooth, even surface.

Floor Sanding and Polishing

Timber floors last for decades under reasonable conditions. But if the do suffer moisture or water damage they can often be restored by re-sanding and re-polishing.
