Hardwood Floor Refinishing:
Complete Process, Costs & Timeline
We supply finishing materials to hundreds of Michigan flooring contractors every year. This guide is what we tell homeowners who want to understand the process — and what separates a great refinish from a job that fails in 2 years.
When to Refinish vs. When to Replace
The first question every homeowner should ask is: does this floor need refinishing, or replacement? After 40 years supplying Michigan contractors, we've seen both mistakes — floors refinished that should have been replaced, and floors replaced that had 3 more refinishes left in them.
Refinish If:
- ✓Surface scratches and dullness (finish worn, not wood)
- ✓Minor staining or discoloration
- ✓Boards are still flat and tight
- ✓At least ⅛" of wood above the tongue groove
- ✓No structural damage or rot
- ✓Squeaks that can be fixed with screws from below
Replace If:
- ✗Boards are cupped, buckled, or warped
- ✗Significant water damage or rot
- ✗Wood is too thin to sand (less than ⅛" above tongue)
- ✗More than 20% of boards need replacement
- ✗Subfloor damage requiring access
- ✗Asbestos-containing adhesive beneath (pre-1980 installs)
The pencil test: Find a floor register or threshold where you can see the edge of the flooring. If you can slide a pencil (¼") between the top of the floor and the top of the tongue groove, you have enough wood for at least one more refinish. If not, replacement is likely the better investment.
The Refinishing Process: Step by Step
Assessment & Preparation
Day 1 (morning)The contractor inspects the floor for protruding nails, damaged boards, squeaks, and moisture issues. All furniture is removed. Nail heads are set below the surface. Damaged boards are replaced. The room is sealed with plastic sheeting to contain dust.
Supplies Needed
- • Nail set
- • Hammer
- • Moisture meter
- • Plastic sheeting
- • Tape
QHM Expert Insight
We always recommend a moisture reading before sanding. Michigan homes with crawl spaces or slab-on-grade can have elevated subfloor moisture that causes cupping after refinishing. A reading above 12% MC warrants investigation before proceeding.
Coarse Sanding
Day 1 (afternoon)A drum sander or belt sander removes the old finish and levels the surface. The first pass uses 36–40 grit paper to cut through the finish quickly. The sander moves with the grain at all times. Edges and corners are done with an edge sander.
Supplies Needed
- • Drum sander or belt sander
- • 36–40 grit abrasive
- • Edge sander
- • Vacuum
QHM Expert Insight
Norton abrasives are our go-to for Michigan contractors. The 36-grit open-coat paper cuts fast without loading up — critical in Michigan's humid summers when finish can be tacky. We stock Norton in all grits at our Rochester Hills showroom.
Medium & Fine Sanding
Day 1 (late afternoon)Progressive sanding with 60-grit, then 80-grit, then 100-grit removes the scratch marks from the previous pass. Each pass must be thorough — skipping grits leaves visible scratches under the finish. Final hand-sanding in corners and along walls.
Supplies Needed
- • 60, 80, 100 grit abrasive
- • Hand sanding block
- • Tack cloth
QHM Expert Insight
The most common DIY mistake is skipping from 40-grit to 100-grit. The 60 and 80 grit passes are not optional — they remove the deep scratches that will show through the finish. We see this mistake regularly when customers call us after a failed DIY refinish.
Stain Application (Optional)
Day 2If a color change is desired, stain is applied with a lambswool applicator or brush, allowed to penetrate for 5–15 minutes, then wiped off. The floor must dry completely (12–24 hours) before finishing. Multiple stain coats can deepen the color.
Supplies Needed
- • DuraSeal or Bona stain
- • Lambswool applicator
- • Rags
- • Gloves
QHM Expert Insight
DuraSeal and Bona are the two stain lines we carry and recommend. DuraSeal has a wider color range and penetrates more deeply. Bona stains are faster-drying and work well under water-based finishes. We stock 40+ stain colors — bring a wood sample to our showroom for a test application.
First Finish Coat
Day 3The first coat of finish is applied with a T-bar applicator or lambswool. Oil-modified polyurethane requires 8–12 hours of dry time. Water-based finish dries in 2–4 hours. The first coat raises the grain slightly — a light screen with 120-grit screen is done before the second coat.
Supplies Needed
- • Fabulon, Basic Coatings, or Bona finish
- • T-bar applicator
- • 120-grit screen
- • Buffer
QHM Expert Insight
Fabulon Classic is our most popular finish for Michigan contractors — it has excellent durability, a warm amber tone, and is forgiving in variable humidity conditions. Basic Coatings Streetshoe is the choice for commercial and high-traffic residential applications.
Second & Third Finish Coats
Days 4–5Two additional coats are applied with light screening between each. Three coats total is the minimum for residential floors. High-traffic areas benefit from a fourth coat. Final coat is not screened — it is the wear surface.
Supplies Needed
- • Finish (same product)
- • T-bar applicator
- • Tack cloth
QHM Expert Insight
We always recommend three coats minimum. Two-coat jobs look fine initially but wear through faster — especially in Michigan homes with sand and salt tracked in from November through April. The third coat adds 30–40% more wear life.

DIY vs. Professional Refinishing: An Honest Assessment
We sell refinishing supplies to both homeowners and contractors. Here's what 40 years of watching both approaches has taught us.
| Factor | DIY | Professional |
|---|---|---|
| Cost | $500–$1,500 (materials + rental) | $3,000–$8,000 (1,000 sq ft) |
| Time | 5–7 days (learning curve) | 3–5 days |
| Dust | Significant — consumer rentals lack containment | Minimal — commercial dustless systems |
| Finish quality | Good if experienced; lap marks common for first-timers | Consistent, professional-grade |
| Stain uniformity | Difficult — blotching and streaking common | Even application with proper technique |
| Risk of damage | High — drum sander can gouge in seconds | Low — experienced operators |
| Best for | Small rooms, screen-and-recoat (no sanding), experienced DIYers | Whole-home projects, stain changes, damaged floors |
Our honest recommendation: If you've never used a drum sander, rent one for a small closet first. The learning curve is real — a drum sander left stationary for 3 seconds will sand through the finish and into the wood. Screen-and-recoat (no sanding, just scuffing the existing finish and adding a new coat) is a much safer DIY project and costs $200–$400 in materials for a 1,000 sq ft floor.
Finish Products We Stock & Recommend
We carry every major professional finish line at our Rochester Hills showroom. Here's how they compare based on 40 years of Michigan contractor feedback.
Fabulon Classic (Oil-Modified Poly)
Oil-modified polyurethaneQHM Insight
Our #1 seller for residential refinishing. Fabulon Classic has proven itself in Michigan's variable humidity for decades. The amber tone is especially beautiful on red oak and walnut.
Basic Coatings Streetshoe (Water-Based)
Waterborne polyurethaneQHM Insight
Streetshoe is the commercial standard. We recommend it for white oak floors where you want to preserve the natural cool tone, and for any floor that will see heavy foot traffic.
Bona Traffic HD (Water-Based)
Waterborne polyurethaneQHM Insight
Bona Traffic HD is the choice when using Bona stains — the systems are designed to work together. Excellent adhesion and scratch resistance. Slightly more forgiving than Streetshoe in humid conditions.
Rubio Monocoat (Hardwax Oil)
Hardwax oil — penetrating finishQHM Insight
Rubio Monocoat is the fastest-growing finish category we sell. It's a one-coat system that penetrates rather than sitting on top of the wood. The result looks and feels like raw wood — and individual boards can be spot-repaired without refinishing the whole floor.
Frequently Asked Questions
How much does hardwood floor refinishing cost in Michigan?
Professional hardwood floor refinishing in Michigan typically costs $3–$8 per square foot, depending on the condition of the floor, number of coats, stain application, and contractor rates. A 1,000 sq ft main floor runs $3,000–$8,000 including materials and labor.
How many times can hardwood floors be refinished?
Solid hardwood floors can typically be refinished 5–10 times over their lifetime, depending on the thickness of the wear layer. Most solid hardwood is ¾" thick with a ¼" wear layer above the tongue — that allows 4–6 sandings. Engineered hardwood can be refinished 1–3 times depending on the veneer thickness.
How long does hardwood floor refinishing take?
A typical hardwood floor refinishing project takes 3–5 days: 1 day for sanding, 1 day for stain application and drying, and 2–3 days for finish coats with drying time between coats. You can walk on the floor lightly after 24 hours but should wait 72 hours before replacing furniture.
What is the best finish for refinished hardwood floors?
For Michigan homes, we recommend oil-modified polyurethane (Fabulon or Basic Coatings) for durability and a warm amber tone, or water-based polyurethane for a clearer, faster-drying finish. Hardwax oil finishes (Rubio Monocoat, Bona Craft Oil) are increasingly popular for their natural look and spot-repairability.
