Sanding and Finishing

Sport Floors Sanding and Finishing

Over time, every gym floor starts to show the effects of its environment—wear and tear, dull finishes, and inconsistent traction. Whether it’s a high school basketball court, a multi-purpose gymnasium, or a volleyball facility, sanding and finishing are essential to maintaining not only the aesthetics but also the safety and performance of your sports flooring.

At J&M Hardwood Floors, we specialize in full-service gym floor refinishing, offering advanced wood finishing solutions backed by decades of hands-on experience. Our process revives worn-out wood flooring, corrects surface issues, and restores the beauty and performance your athletes deserve.

Why Sanding and Finishing Matter

Unlike routine gym floor maintenance like buffing or screening, full sanding removes old floor finishes, exposing a fresh surface of raw hardwood flooring. This allows us to correct issues caused by moisture, UV exposure, or years of foot traffic.

Sanding and refinishing is especially critical for:

Removing surface-level damage and embedded debris
Replacing outdated court lines or logos for tennis, racquetball, or squash
Correcting issues like water damage, finish failure, or poor traction
Reapplying polyurethane or lacquer-based floor finishes to improve playability

Our finishing options include both water-based and solvent-based systems, selected based on performance goals, facility use, and LEED compliance when required.

Our Sport Floor Sanding & Finishing Process

We use commercial-grade equipment, professional-grade sandpaper, and top-tier sealers and finishes to deliver results that perform.

Step 1

Deep Sanding

Using state-of-the-art scrubbers and sanding machines, we remove the existing finish and a thin layer of surface wood. This eliminates old sealant, imperfections, and deep-set dirt or odor buildup.

Step 2

Inspection and Repairs

Our team examines the gymnasium floor for loose boards, cracks, or signs of water damage. Any problem areas are repaired to ensure stability and longevity.

Step 3

Game Line Layout & Custom Design

Once the surface is prepped, we apply fresh game markings tailored to your needs—whether it’s for basketball, volleyball, tennis, or strength training zones. Logos and branding can also be stenciled with precision.

Step 4

Finish Application

We apply multiple coats of MFMA-approved polyurethane or alternative floor finish depending on the facility’s needs. These finishes are selected for their durability, safety, and compatibility with ongoing gym floor care.

Step 5

Final Curing & Quality Check

After proper drying time, we conduct a thorough inspection, test traction, and review the final surface for shine, uniformity, and cleanliness.

Frequently Asked Questions (FAQ)

How often should a gymnasium floor be sanded and refinished?

Depending on usage, every 8–12 years is standard. High-use facilities may require refinishing sooner, especially if gym floor finishes begin to fail or moisture issues arise.

What’s the difference between refinishing and screening?

Refinishing involves sanding to bare wood, while screening is a light abrasion to the top coat. Screening is best for routine gym floor maintenance, while sanding addresses deeper issues and allows for full redesigns.

Are your finishes safe and environmentally friendly?

Yes. We offer environmentally friendly water-based options that are low in odor and VOCs and qualify for LEED credits where applicable.

Can sanding help remove stains or water damage?

Absolutely. Sanding can remove surface stains and help mitigate light to moderate water damage, though severe damage may require board replacement

What types of finishes do you offer?

We apply both oil-modified and water-based polyurethane finishes, depending on your facility’s performance needs, drying schedule, and floor care plan.
