How often you recoat or repair your floor will depend on several factors including the type of floor it is, its finish and the wear its experienced. However, as a basic preventative, you might consider recoating your floor every two or three years. Don’t wait until your floor looks worn. If you allow the protective coat to wear away, it becomes susceptible to dirt and water penetration and harder to clean and repair.
A good way to check whether your floor needs treatment is to pour a few drops of water onto its surface. If the finish is in good order, the water will bead on the floor and can easily be wiped way. No maintenance is needed. If the water slowly soaks into the timber, leaving behind a light saturation mark, the finish is starting to wear thin. A new coat of lacquer or oil should be applied. However, if the water is immediately absorbed and leaves a dark stain, the finish has been completely worn away and the floor may need sanding and recoating.
