Buff & Recoat Vs Full Sand & Refinish

What Is Buff & Recoat?

A buff & recoat (also called a screen & recoat or light sand) is a maintenance service that refreshes the protective finish on your hardwood floors without sanding down to bare wood. Here's what the process involves:

Light abrasion — a buffing machine with a fine abrasive screen scuffs the surface of the existing finish, creating a mechanical bond for the new coats
Cleaning — the abraded surface is thoroughly cleaned and vacuumed
New finish — 2 fresh coats of water-based finish are applied over the existing floor

The entire process is less invasive than a full sand — no heavy equipment, less dust, faster completion. It's also significantly less expensive. What it cannot do: A buff & recoat cannot change the colour of your floor, cannot remove deep scratches that have penetrated the finish into the wood, and cannot be performed on floors that have wax or oil contamination.

What Is Full Sand & Refinish?

A full sand & refinish is a complete floor restoration. It involves:

Heavy sanding — a drum sander removes the existing finish and a layer of wood, taking the floor back to bare wood
Edge sanding — an edge sander addresses the perimeter that the drum sander can't reach
Staining (optional) — stain is applied to the bare wood if a colour change is desired
Sealing and finishing — 3 coats of water-based finish are applied with light sanding between coats

The result is a floor that looks completely new — and because you're starting from bare wood, there are no limitations on colour, sheen level, or finish type.

When Buff & Recoat Is the Right Choice

Choose a buff & recoat when all of the following are true:

Your floor has surface dullness but no deep scratches through the finish
You're happy with the current colour
There's no wax, oil, or polish buildup on the floor
The floor hasn't had more than 1–2 previous buff & recoat services without a full sand in between
The floor was last refinished within the past 8–12 years

A buff & recoat done at the right time — before the floor is heavily worn — is one of the best investments a Toronto homeowner can make. It extends the life of the floor and keeps it looking fresh at a fraction of the cost of a full refinish.

The Preventive Maintenance Principle The ideal maintenance schedule is a buff & recoat every 4–5 years, with a full sand & refinish every 10–15 years. Staying on this schedule means your floor never gets to the point where it looks terrible — and the total cost over the floor's lifetime is significantly lower.

When Full Sand & Refinish Is Necessary

A full sand & refinish is necessary when:

Deep scratches have penetrated through the finish into the wood
You want to change the colour of your floor
There is wax, oil, or polish contamination that chemical stripping alone can't address
The floor has been buff & recoated multiple times and the finish is no longer adhering properly
There is significant staining or discolouration in the wood itself
The floor has structural surface issues (minor cupping, grain raise) that need to be levelled

The Wax Problem — Why It Changes Everything

This is the single most common reason a buff & recoat fails — and it's something many refinishing companies don't explain clearly enough upfront. If your floor has been treated with any wax-depositing product — Rejuvenate, Mop & Glo, Murphy's Oil Soap, Quick Shine, or similar — a buff & recoat will almost certainly fail. The new finish will not bond to the wax contamination and will begin to peel within days or weeks of application. Before a buff & recoat can be performed on a contaminated floor, the wax must be chemically stripped. This is an additional step and cost. In some severe contamination cases, the only real solution is a full sand — which physically removes the contamination by removing the top layer of wood along with the finish. At MKZ, we test every floor for wax contamination before recommending a service. If your floor has been treated with polish products, we'll tell you — and tell you exactly what needs to happen before the floor can be properly refinished.

Timeline Comparison

Buff & recoat — typically 1–2 days. Light foot traffic in 4 hours of final coat. Furniture back in 48 hours
Full sand & refinish — typically 4–5 days for a 1,000 sq ft floor. Light foot traffic in 4 hours of final coat. Furniture back in 48–72 hours. Rugs after 7 days

Both services use water-based finish, which is why the dry times are similar despite the additional steps in a full refinish. Oil-based finish alternatives take significantly longer to cure — another reason MKZ uses water-based exclusively.
