One of the most common questions we hear from homeowners: “Do I need a full hardwood floor refinish, or can I get away with a buff and re-coat?” Knowing the difference between a hardwood floor refinish and a buff and re-coat can save you real time and money — and this guide will help you figure out exactly which one your floor needs.
What Is a Buff and Re-coat?
A buff and re-coat (also called a “screen and re-coat”) is a maintenance service that lightly abrades the existing finish using a buffer and applies one or two fresh coats of finish on top. There is no sanding down to bare wood and no stain changes. The process typically takes one day, costs significantly less than a full refinish, and floors are ready for light foot traffic within 24 hours.
A buff and re-coat is an effective way to restore the lustre of a dull floor and remove most topical, surface-level scratches — the kind that live only in the finish layer. However, it is important to understand what this service cannot do: a buff and re-coat will not remediate deep scratches that have penetrated through the finish into the wood itself. If the scratch catches your fingernail or you can feel it with your fingertip, it has likely reached the wood fibre, and a re-coat will not make it disappear. Those types of scratches require a full refinish.
Good candidates for a buff and re-coat: dull or lightly scratched finish, surface scuffs and traffic patterns with no wood damage, finish that is still mostly intact and adhering properly.
What Is a Full Hardwood Floor Refinish?
A full refinish means sanding the floor completely down to bare wood, then applying stain (optional) and two to three new coats of finish. This process resets the floor entirely — removing deep scratches, stains, discolouration, and years of wear. Because it involves multiple sanding passes, stain cure time, and finish coat dry times between applications, a full refinish takes approximately five days on average from start to when the floor is ready for furniture and normal use.
Industry guidelines from the National Wood Flooring Association (NWFA) and finish manufacturers like Bona point to a consistent benchmark: a well-applied finish on a properly maintained hardwood floor should hold up for roughly seven to ten years before a full refinish becomes necessary. That said, real-world lifespan varies considerably based on the type of finish used, the volume of foot traffic the floor sees, how it’s cleaned day-to-day, and whether protective mats and pads are used in high-wear areas. Waterborne finishes on floors with lighter traffic and good maintenance routines can stretch well beyond that range — sometimes 15 years or more.

How Do You Know When It’s Time for a Full Refinish?
The NWFA and flooring professionals recommend watching for these key indicators that a full refinish — rather than a simple re-coat — is needed:
- Finish worn through to bare wood — You can see or feel exposed, unprotected wood in high-traffic areas like hallways or in front of the kitchen sink.
- Deep scratches into the wood fibre — Scratches that catch a fingernail and cannot be buffed out at the finish level require full sanding to remove.
- Graying, blackening, or water staining — Discolouration that has penetrated into the wood itself cannot be corrected by adding finish on top.
- Peeling, flaking, or bubbling finish — Once a finish has lost adhesion and is delaminating, a re-coat will not bond properly and a full sand-down is required.
- Desire for a colour change — Changing the stain colour requires sanding to bare wood.
- Multiple re-coats already applied — If a floor has been re-coated several times, finish build-up can cause adhesion issues; a full refinish restores a clean, even base.
One Critical Factor for a Successful Hardwood Floor Refinish
A re-coat will only succeed if the new finish is chemically compatible with the existing one. Applying a waterborne finish over an oil-based finish — or vice versa — causes adhesion failures, peeling, and a result that looks worse than before you started. This is one of the most common reasons DIY re-coats fail. The NWFA‘s Hardwood Floors: Sand and Finish guidelines specifically address finish compatibility testing before any re-coat application, which is why a professional assessment matters before proceeding with either service.
