Screen-and-Recoat or Full Refinish: How to Tell Them Apart
"Recoat" and "refinish" get used loosely in everyday conversation, but they describe two different amounts of work, and using the wrong one on a floor that needs the other either wastes money or doesn't fix the actual problem. The distinction comes down to how much of the existing finish, and how much of the wood itself, gets removed.
What each term actually means
The National Wood Flooring Association draws the line clearly. A maintenance coat — often called a screen and recoat — "involves cleaning the existing floor finish, then lightly sanding it, and application of a fresh new coat of wood floor finish." Nothing about the wood itself changes; only the top layer of finish is lightly abraded and renewed. A resand, by contrast, comes into play "when a new coat of finish doesn't meet the needs of the floor" — the finish alone isn't enough to fix what's wrong. A complete sand and refinish goes further still, removing the finish down to bare wood, and NWFA recommends it "when there is damage to the wood floor like deep scratches, dents, and other flooring damage," or "when the finish has worn away, and the bare wood is exposed." NWFA is careful not to attach a number to any of this — how many times a floor can be sanded over its life "varies depending on a variety of factors including the skill of the contractor, the equipment used, the thickness of the wear layer, the flatness of the floor and the condition of the floor," and no fixed count is used here either.
One upside NWFA points out for the full-refinish route: since the floor is already being sanded to bare wood, that's also the moment to change the floor's color if a different look is the goal — something a recoat, by definition, can't do.

How a manufacturer frames the same idea
Bona, a finish manufacturer, describes its own three-tier product lineup for homeowners in similar but not identical terms: polishing (a fresh layer applied over the existing finish), recoating (the finish is lightly scuffed, then a new coat applied), and refinishing (the existing finish is "completely" removed). It's worth being clear that this three-way split is Bona's own product-line framing, not an industry-standard classification — NWFA's public guidance describes two main categories (a maintenance coat, and a full sand and refinish), not three. Bona's own description of recoating calls it "excellent preventative maintenance," and separately notes that a floor's finish wears down gradually with daily use — bare wood is eventually exposed if a floor goes too long without any maintenance coat, at which point Bona says a complete refinish becomes necessary. Bona's professional guidance for its own recoat process describes light abrasion with 240-grit before the new coat goes down.
Why a recoat can fail to bond
A recoat only works if the new finish can actually bond to what's underneath it, and that's where recoats can go wrong. Bona's technical data sheet for its Traffic HD finish is direct about the risk: before recoating, the floor "must be free of wax, polish and oily residues, or adhesion failure can occur." Wax-based cleaning products, furniture polish, and certain oil soaps can leave a film on the finish that a light screening pass doesn't fully remove, and a new coat applied over that residue may not adhere properly — which can mean peeling or flaking not long after the work is done. That's one reason it's worth mentioning any past cleaning products used on a floor before a screen and recoat is scheduled, so the surface can be properly prepped rather than assumed clean.
Picking the right one
A dulling finish with no exposed wood and no deep damage is generally a recoat candidate; bare wood, deep gouges, or a desired color change point toward a full refinish instead. The two jobs also differ sharply in scope: a recoat works on the finish layer alone and can typically be turned around much faster than a full resand, while a complete refinish involves sanding the entire floor down to bare wood before any new finish goes on — closer in scale to a full renovation than a touch-up. Bona's own homeowner guidance frames a recoat as "ready overnight" and a full refinish as taking "2-4 days," though those figures describe Bona's own branded process rather than a guarantee for any specific job or product.
Getting the call wrong runs in both directions. Recoating a floor that actually needs a full resand leaves the underlying damage or bare-wood exposure unaddressed, since a fresh coat over worn-through finish doesn't restore wood that's already exposed. Going straight to a full refinish on a floor that only needed a recoat means paying for, and losing time to, a much larger job than the floor's actual condition called for. Caring for refinished floors covers the cleaning habits that stretch out the time between either one being needed in the first place.
