How to sand a wooden floor
Sanding a wooden floor.
- Clear the room and seal it to keep the dust from escaping. The job you are about to do will be a dusty job!
- If the floorboards are uneven and the gaps prove too wide to close, your only real solution will be to replace them or fit small scetions of timber infills.
- You can fill minor holes with wooden plugs or wood filler.
- Hammer in all protruding nails or remove them, if hammering them in please check for any concealed pipes or cables that may be under the floor.
- To sand your floor, you will need to hire or buy a floor sanding machine and a belt sander, to finish off the corners, buying is probably unwise.
- Start by sanding the floors with the floor sanding machine, working diagonally and using the coarsest grade of sandpaper. Move the machine at a slow walking pace, sanding at a 45 degree angle to the floorboard.
- Replace the sanding belts when needed and empty the dust bag regularly.
- Stop sanding when you feel bare wood, this is more likely to be a visual check.
- When you're finished sanding the floor diagonally, change to a medium grade sandpaper, and sand the floor parallel to the floorboard, again check visually and physically to guage if the flooring is sanded properly.
- Lastly, use a belt sander to sand corners. Again start with the coarsest grade to medium, and finish off with the finest grade of sandpaper.
- Hand-sand any inaccessible areas.
- Remember not to concentrate on any one spot for too long as it will unevenly dent or damage the floorboard.
- When you are finished sanding, vacuum or sweep the floor.
- Wipe the floor with white spirit, wear gloves and be careful of splashes especially in relation to your eyes.
- Apply at least one coat of floor sealer.
