Is it possible to sand and varnish semi solid flooring?

I have a semi-solid maple floor that has gotten worn and grubby looking in places like the back door enterance. Is it possible to give it a light sand and varnish to try and restore it? Did anyone ever try?

Don't know what a semisolid floor is, but we clean our woodblock floors with a mixture of 75% white spirit and 25% boiled linseed oil and then put danish oil on them. The oil takes quite a while to dry but gives a nice sheen finish.

semi-solid is more like a laminate flooring, i'm not sure if I go to sand it that it will break up on me...

I have semi-solid floor and have it sanded and varnished and it came up as new. Semi solid has layer of solid wood on top of a base of I think MDF.I know that the sales person told me you could sand the floor about three times and after that there was a danger you would have sanded of all the solid wood and be down to the base.

Yes it is possible but make sure you research and spend the money on an expensive finish.
