The one question that decides it
Every floor we look at gets the same question: is the damage in the finish, or is it in the wood? That single distinction determines which job you need and it is the difference between a one day service and a week long project.
The finish is the clear protective layer on top. The wood is what it protects. Scratches, dullness, and traffic lanes that live in the finish can be abraded and recoated. Anything that has reached the wood itself, greying, water stains, deep gouges, cannot be covered up. It has to be sanded out.
How to test it yourself
There is a simple check you can do before we arrive. Find the worst looking area, usually a hallway or the path from the garage door to the kitchen. Put a few drops of water on it. If the water beads and sits, the finish is still intact and doing its job. That floor is a candidate for a buff and recoat.
If the water soaks in and darkens the wood within a minute or two, the finish is gone in that spot and the wood is exposed. Once bare wood has been walked on it picks up dirt and moisture, and that greying goes into the fibre. A recoat over that just locks the damage in under a fresh shine.
What a buff and recoat actually does
A buff and recoat, also called a screen and recoat, uses an abrasive screen to scuff the existing finish so a new coat will bond to it. Then a fresh coat of finish goes down. The floor is not sanded to bare wood, no stain is applied, and the colour does not change.
It typically takes about a day, and cure time is shorter than a full refinish because you are applying one coat rather than three. It is the cheapest way to reset the protective layer, and done on schedule it can push a full sanding out by years.
What a full sand and finish does
A full sand and finish, which is the same thing as refinishing, takes the floor back to raw wood. That removes the old finish entirely along with the top layer of wood and everything embedded in it: greying, pet stains, water marks, and scratches. Damaged boards get replaced, gaps get filled, and then the finish is rebuilt from scratch with multiple coats.
This is also the only path if you want to change colour. Stain cannot go over an existing finish. If you want lighter, darker, or a different tone entirely, the floor has to come to bare wood first.
Why timing a recoat saves money
Solid hardwood can only be sanded so many times. Every full sand removes wood, and there is a finite amount above the tongue. A floor that gets recoated every several years may never need a second full sanding in its life. A floor that is left until it greys will need one.
That is the practical argument for paying attention to your finish before it fails. A recoat is the cheap, boring, correct maintenance step, and it is the one most homeowners skip until it is too late to use it.
Where it gets complicated
Some floors do not take a recoat well. Floors that have been cleaned with oil soaps or waxed products can reject a new finish, causing it to bead or peel. Some factory finished floors have aluminium oxide coatings that are difficult to abrade properly. And a floor with a few genuinely damaged boards in an otherwise good field may be best served by board replacement plus a recoat rather than either extreme.
This is why we test on site rather than quoting from a photo. We check adhesion in an inconspicuous spot before recommending a recoat, because a recoat that does not bond is worse than no recoat at all.
What each job feels like to live through
A buff and recoat is a single day event. The floor is cleared, screened, vacuumed, and coated. There is noise for a few hours and a low odour with a waterborne product. Light foot traffic usually returns the next day, and furniture within a couple of days depending on the finish.
A full sand and finish is a genuine project. Sanding runs a day or more depending on square footage, and it is loud. Then coats go down on successive days, each needing to dry before the next. Furniture stays off for days and rugs stay off longer, because a curing finish needs to breathe.
Both are dustless in our work, with HEPA extraction at the sanding head, so neither requires you to move out of the house in most cases. But the difference in disruption between one day and a week is worth weighing when the technical answer could go either way.
A maintenance rhythm worth adopting
The floors that stay out of trouble are the ones with a boring routine. Sweep or vacuum grit regularly, because sand and dirt are abrasives underfoot and they do most of the damage to a finish. Use a cleaner made for hardwood rather than anything oily, waxy, or steam based. Put mats at the doors people actually use.
Then check the traffic lanes once a year with the water drop test. When water stops beading in the busiest path, that is the signal to book a recoat. Doing that reliably is how a floor reaches its second or third decade having only been fully sanded once, which is a meaningful saving over the life of a house.
Common questions
How often should hardwood floors be recoated?
It depends entirely on traffic rather than on a fixed schedule. Busy households wear a finish through faster than quiet ones. The practical rule is to recoat when the finish is visibly worn in traffic lanes but before bare wood shows anywhere.
Can I recoat over a waxed floor?
Usually not. Wax and oil soap residues prevent a new finish from bonding. If a floor has been waxed, it generally needs a full sand to get a modern finish to adhere. We test adhesion before recommending a recoat.
Will a recoat remove scratches?
It will soften and hide light scratches that live in the finish. It will not remove anything that has cut into the wood. Those need a full sand.
Can I change colour with a buff and recoat?
No. Stain has to go onto bare wood, so a colour change always requires a full sand and finish.
Which one is cheaper?
A buff and recoat is substantially cheaper because it is one day and one coat with no sanding, staining, or board work. We quote both by free in-home written estimate so you can compare on your actual floor.
