Professional Hardwood Floor Refinishing

Why Refinish Your Hardwood Floors?

Hardwood floor refinishing breathes new life into worn, scratched, or dated floors, restoring their original beauty at a fraction of replacement cost. Professional refinishing not only enhances your home's appearance but also protects the wood, extends floor life by decades, and can increase property value. With modern dustless techniques and durable finishes, refinishing is an investment that transforms your space while preserving the character and warmth only real hardwood provides.

Signs Your Floors Need Refinishing

Visual Indicators

• Worn finish - Dull areas where finish has worn through
• Deep scratches - Scratches penetrating through finish to wood
• Discoloration - Gray or black areas from water damage
• Board separation - Gaps between boards from seasonal movement
• Sun fading - Uneven color from UV exposure

Performance Issues

• Water no longer beads on surface
• Rough texture catching socks or pet paws
• Squeaking or loose boards
• Difficulty cleaning due to worn finish
• Splinters or raised grain

When NOT to Refinish

• Engineered wood with thin veneer (less than 2mm)
• Floors already refinished multiple times
• Severe structural damage requiring replacement
• Laminate flooring (cannot be refinished)
• Minor surface scratches (try recoating instead)

The Professional Refinishing Process

1. Assessment & Preparation

• Inspect floor thickness and previous refinishing
• Test for lead paint (homes built before 1978)
• Remove all furniture and wall decorations
• Seal off work area to contain dust
• Remove or protect baseboards

2. Sanding Process

• Coarse sanding - Remove old finish and level floor (36-60 grit)
• Medium sanding - Smooth surface and remove scratches (80 grit)
• Fine sanding - Prepare for finish application (100-120 grit)
• Edge sanding - Detail work along walls and corners
• Vacuum and tack - Remove all dust between grits

3. Staining (Optional)

• Apply wood conditioner for even stain absorption
• Test stain colors in inconspicuous area
• Apply stain evenly following grain direction
• Remove excess and allow proper drying time
• May require multiple coats for darker colors

4. Finishing Application

• First coat - Seal wood and raise grain slightly
• Light sanding - Smooth raised grain (220 grit)
• Second coat - Build protection and sheen
• Final coat(s) - Achieve desired durability and appearance
• Curing time - Allow proper hardening before use

Choosing the Right Finish

Oil-Based Polyurethane

• Pros: Extremely durable, amber glow enhances wood, self-leveling
• Cons: Strong odor, 24hr dry time between coats, yellows over time
• Best for: Traditional homes, high-traffic areas
• Sheen options: Matte, satin, semi-gloss, gloss

Water-Based Polyurethane

• Pros: Low odor, fast drying (2-4 hours), crystal clear
• Cons: More expensive, requires more coats, raises grain more
• Best for: Light woods, contemporary looks, quick turnaround
• Durability: Excellent with modern formulations

Swedish Finish (Acid-Cured)

• Pros: Extremely hard and durable, beautiful clarity
• Cons: High VOCs, requires vacating home, professional only
• Best for: Commercial spaces, sports floors
• Note: Less common due to environmental concerns

Hard Wax Oil

• Pros: Natural look and feel, spot-repairable, low VOCs
• Cons: Requires more maintenance, less water protection
• Best for: Low-traffic areas, natural aesthetics
• Maintenance: Annual reapplication in traffic areas

Dustless Sanding Technology

• Avoid wet cleaning for first month

Long-Term Maintenance

• Use manufacturer-recommended cleaners only
• Maintain 30-50% humidity year-round
