How do I refinish a wood floor?
user
Refinishing a floor means applying a new coating, usually one that is more durable than the old one, so that it is more resistant to wear and can last longer.  This is done by sanding, cleaning, and sealing it.

Should I do a light sanding or a heavier sanding on the floor?
user
Generally, the heavier the sanding, the less there is of the old coating, and the better the new coating can attach to the floor.  But light sanding is better if there are lots of furniture or decorations to avoid damaging.

What do I do after I sand the wood floor?
user
When you are done sanding, you should apply a pre-finish cleaner. This is a solvent that removes all of the dirt and grime from the wood flooring and allows the new coating to stick to the wood much better.  Then, you should apply a finish coat of stain or oil-based lacquer to give the wood the final protective coating, along with a shine.
