Helpful Tips Sanding A Floor
Remember that if you are decorating a room and sanding a floors at the same time, you should first complete decorating the room and then take up sanding floor boards.
For sanding floorboards that are in a good condition (without uneven edges, without crowning or cupping) sanding can be done along the grain using a coarse or a medium grit abrasive to begin with. On the other hand, if the floor happens to be uneven, sanding a floor can be done diagonally at 45° in both directions across the room. The abrasive used can be coarse grit.
It is always advisable to begin sanding floor boards with a test sand using a medium or fine grit abrasive first. This is because care should be taken to ensure that as little wood as possible is removed in the sanding process.
Care should be taken to ensure that not more than one intermediate grit is skipped when changing from one abrasive grit to the next.
In parquet floors, the grain runs in various directions. So, when sanding a parquet floor, sand in the direction of the natural light. In the absence of natural light, if the room is rectangular, sand in the direction of the longest side; if it is square, then sand in the direction in which people would walk.
