The floor of every kitchen has to have a perfect upper surface. It's important to keep the floor from bumps, scratches, and the protect the sub-floor from water drops or fluids.
That's the reason to make a reliable sanding of solid wooden floor. It's better to use a higher level of protection with staining and varnishing. Sometimes oiling can be a good decision, but in most cases it has to be a durable mixture.
If you live in Redbridge, and you need a stable wood floor surface, you can make a complete restoration, or just to seal the floor from any further problems. It works with gap filling, light or full sanding, and matt colour.
