This updated guide walks homeowners through the hardwood refinishing decision: confirm the floor type, study manufacturer and NWFA guidance, choose the right tools and low-VOC finishes, and decide between DIY and hiring a pro. Emphasized are dust control, safety (respirators, ventilation), small test areas for stains, and getting help to move furniture and manage logistics.
Why Refinish? What to Expect
Hardwood floors add warmth and resale value to a home. Refinishing restores worn finish, removes surface scratches, and can change color or sheen. Before you start, confirm the floor is solid hardwood (can usually be sanded) rather than thin-veneer engineered wood, which may only tolerate light screening.Learn the Process First
Refinishing involves surface preparation, sanding or screening, stain (optional), and applying finish coats. Read manufacturer guides from finish brands (for example, Bona or Minwax) and the National Wood Flooring Association (NWFA) for technique and safety recommendations. Watch short how-to videos from reputable manufacturers or trade groups to see each step before you try it.Decide DIY vs. Professional
Refinishing is physical and dusty work with a learning curve. If you're comfortable with power tools, protective gear, and following step sequences, DIY can save money. If the floor has deep damage, major cupping, or you need color matching across rooms, hire a qualified flooring contractor who can also advise on moisture testing and warranties.Tools, Safety, and Environmental Considerations
Rentally available equipment now often includes dust-containment sanders and HEPA-rated vacuums that dramatically reduce cleanup and airborne dust. Use N95 or better respiratory protection when sanding. For finishes, water-based polyurethane and low-VOC products are widely used today because they dry faster and have lower odors than older solvent-based finishes.Practical Tips for Better Results
- Test a small, out-of-sight area to confirm stain color and sheen.
- Work in logical sections and keep a wet edge when applying finishes to avoid lap marks.
- Allow adequate cure time between coats per the finish manufacturer's instructions.
- Enlist at least one helper for moving furniture, holding doors open, and managing ventilation - this shortens the project and reduces mistakes.
Where to Get Help and Reliable Information
- Manufacturer websites (Bona, Minwax, etc.) for product instructions and tech sheets.
- NWFA for industry standards and contractor directories.
- Big-box home improvement stores and local flooring retailers for tool rentals, product lines, and referrals to local installers.
- Reputable trade videos and forums for technique tips - prioritize content from manufacturers, associations, and certified pros.
Final Thought
Refinishing hardwood is a rewarding upgrade that restores character and extends the life of your floors. Invest time in learning basic techniques, choose the right products, plan for proper ventilation and dust control, and get help for physically demanding steps. The result is a healthier, refreshed floor that can last for years.FAQs about Refinishing Hard Wood Floors
How do I know if my floor can be refinished?
Solid hardwood with sufficient thickness can usually be sanded and refinished. Thin engineered floors may only accept light screening and recoating. If you're unsure, check manufacturer info or ask a flooring specialist to inspect the plank thickness and condition.
Can I refinish floors myself or should I hire a pro?
DIY is possible if you're comfortable with power tools, sanding techniques, and following product instructions. Hire a professional for major damage, moisture issues, color matching across rooms, or when you want guaranteed results and faster turnaround.
What finish should I use?
Water-based polyurethanes and low-VOC finishes are common today because they dry faster and have lower odor than older solvent-based products. Follow manufacturer data sheets for application and cure times.
How can I minimize dust and health risks?
Use dust-containment sanders and HEPA vacuums when possible, wear an N95 or better respirator during sanding, and ventilate the space according to product guidelines. Dust control improves cleanup and indoor air quality.
