Floors
in California highly recommends
recoating your
floor every few years. (Between
3 to 7, depending on how heavily
they are used). Recoating
your floor will significantly
extend the life of the hardwood
floor in general, and allow
considerably more time to
pass before the wood floor
will need to be refinished
again. Recoating a wood flooring
basically replaces the top
coat of finish as it wears
down, before the wood is exposed.
Once the wood loses its protection
and is exposed it will begin
to turn gray, and will need
sanding in order to be restored.
