Homeowners often face a choice when hardwood floors show wear: refinishing or resurfacing. Refinishing removes the old finish and reveals fresh wood to stain and seal, delivering a durable, like-new look. Resurfacing, commonly called screening and recoating, restores the surface gloss with minimal wood removal and preserves most of the existing color. Each method has advantages, costs, and limits, depending on floor condition, traffic, and desired outcome. This guide explains the differences, helps you decide which option fits your house, and offers practical tips for selecting a contractor, planning the project, and maintaining floors afterward.
What Is Hardwood Floor Refinishing?
Refinishing is a comprehensive process that removes the current finish and typically a thin layer of the wood itself. After sanding, the floor is custom stained (optional) and finished with multiple coats of sealant, usually polyurethane. The result is a renewed surface with deeper color options and improved protection against wear. Refinishing is best when the existing finish is deeply worn, scratches are widespread, or the floor has water damage or stains that cannot be addressed by a surface recoat.
The sanding phase uses machines such as a drum sander and edgers to reach bare wood. Gaps, loose boards, and cracks are repaired with wood filler. After cleaning, a stain can be applied to achieve a new color, followed by a durable topcoat. Because wood is removed and color can change, refinishing is more disruptive and requires longer drying times between coats. Proper ventilation and dust control are essential due to the dust produced during heavy sanding.
What Is Hardwood Floor Resurfacing?
Resurfacing refers to removing only the surface layer of finish and a light amount of wood erosion, often through a screen and recoat process. This method preserves most of the existing wood color and grain, offering a quicker, less invasive option. After light sanding, the floor is cleaned and a fresh coat of finish is applied, typically with two or more coats. Resurfacing is ideal for floors with minor wear, small scratches, or when the current color and tone are already pleasing and do not require staining.
Because only the surface is touched, resurfacing minimizes dust, downtime, and cost. However, it cannot repair deep gouges, severe cupping, or sun-damaged boards. If the floor has warped boards or structural issues, resurfacing may not be suitable and could require more extensive fixes or replacement. The longevity of a resurfaced floor depends on traffic, maintenance, and the quality of the new finish used.
Differences And When To Use Each
- Depth of sanding: Refinishing removes more wood to bare or near-bare wood; resurfacing involves light sanding and resealing.
- Color change: Refinishing allows changing color with stain; resurfacing preserves existing color unless a stain is reapplied in a later step.
- Damage correction: Refinishing addresses deeper scratches, gouges, and water damage; resurfacing fixes only surface wear.
- Downtime and mess: Refinishing takes longer and creates more dust and disruption; resurfacing is faster with less dust.
- Cost: Refinishing generally costs more per square foot than resurfacing due to materials and labor.
Process And Materials: Refinishing vs Resurfacing
Refinishing Steps
Preparation includes moving furniture, removing baseboards, and sealing the area. The floor is sanded with coarse grits to remove the old finish and a thin wood layer, then progressively finer grits to a smooth surface. Repairs are made with wood filler, and the surface is thoroughly cleaned. If color change is desired, staining is applied and allowed to dry. Finally, two to three coats of topcoat polyurethane are applied, with drying time between coats. Ventilation and dust containment are crucial throughout.
Resurfacing Steps
The process begins with masking and dust containment, followed by a screen sanding that abrades the existing finish without removing much wood. After cleaning, the floor may receive minor repairs or fill gaps. A fresh topcoat is then applied, typically in two coats, to restore gloss and protection. If a color change is needed after resurfacing, a new stain can be introduced, but this effectively becomes refinishing. The entire resurfacing workflow tends to be quicker and generates less waste than a full refinishing job.
Cost, Downtime, And Longevity
| Aspect | Refinishing | Resurfacing (Screen & Recoat) |
|---|---|---|
| Typical cost per sq ft | $3–$8 | $1.50–$4 |
| Downtime | 3–5 days for larger rooms or multiple coats | 1–2 days |
| Depth of material removal | Full finish removal and light wood thinning | Topcoat only with light surface abrasion |
| Color change options | Yes, staining is common | Typically no color change unless re-stained later |
| Longevity after service | 10–25 years, depending on traffic and maintenance | 5–10 years, depending on traffic and maintenance |
Maintenance And Longevity
Both refinishing and resurfacing benefit from proper care. Use felt pads under furniture, avoid standing water, and maintain humidity levels to prevent wood movement. Regular dusting and damp-mopping with a well-wrung cloth protect the finish. Use area rugs in high-traffic zones and reapply a reputable topcoat when sheen fades or scratches become noticeable. A high-quality finish and proper curing time extend the life of either approach, but refinished floors may tolerate more aggressive use before another major service is needed.
DIY Or Professional: Which Is Right?
Refinishing and resurfacing are technically doable by skilled DIYers for small spaces, but both involve heavy machinery, dust control, ventilation, and precise finish application. In most cases, hiring a licensed flooring contractor ensures proper thickness removal, dust containment, proper stain color, and warranty protection. For large rooms, multiple rooms, or historical homes with delicate finishes, professionals provide consistent results and better protection against future wear.
Choosing A Contractor
- Licensing and insurance: Verify liability and workers’ compensation coverage.
- Portfolio and references: Review recent jobs and contact past clients.
- Product warranties: Ask about finish warranties and maintenance plans.
- Dust containment and cleanup: Ensure a plan to minimize and manage dust.
- Timeline and disruption: Get a written schedule and contingency plans for delays.
