Hardwood floors offer timeless beauty and practicality in commercial spaces. With its sustainable, natural, and renewable properties, hardwood flooring can last a lifetime with proper care. However, over time, it may become scratched, faded, or discolored. Facility managers often think replacing the flooring is the only option, which can be costly, time-consuming, and disruptive, especially in high-traffic areas.
But there’s a more cost-effective solution: refinishing. It’s a great way to save money while reviving worn, dull, and stained floors. Whether you’re changing the color and texture or refreshing the existing look, refinishing not only restores the aesthetic appeal but also enhances the floor’s durability.
Sanding, Staining, and Sealing Process
The first step in the hardwood renovation process is sanding off the old finish and stain to expose the bare wood beneath. In the past, sanding was a health hazard due to airborne dust, and the downtime required for preparation and clean-up was extensive. Unfortunately, this often left dust particles in the final finish, affecting both air quality and the end result.
Today, dust containment sanding (DCS) technology is an industry standard, providing a safer, cleaner work environment. This modern method minimizes airborne dust, resulting in better-quality finishes and quicker turnaround times since there’s less preparation and clean-up.
Once the floor is sanded, it can be stained to achieve the desired color or aesthetic. Wood stains are available in various shades, and many can be mixed for custom colors. Waterborne stains, which are newer to the market, offer a highly sustainable option with the same benefits as traditional oil-modified stains.
If staining is not needed, most floors require a sealer. A sealant penetrates and seals the wood, providing a base for the finish. Some contractors may skip the sealing process to save costs, but this can lead to premature maintenance and unsatisfactory results. Sealers ensure durability and protection by preventing reactions from the natural oils, resins, and minerals in the wood. They also reduce the risk of tannin discoloration and enhance the wood’s natural tone.
A Strong Finish
The quality of finishes for hardwood floors has greatly improved over the years. While older finishes like varnishes and lacquers required extensive safety precautions, there are now better options available. Though some contractors still use traditional finishes like acid-cure or Swedish finishes, waterborne finishes have become the industry standard.
Waterborne finishes are high-performing and durable, with low volatile organic compounds (VOCs). These finishes dry quickly—typically in two to three hours per coat—and fully cure in as little as three days. They also provide a clear, non-yellowing coating that maintains its appearance over time.
When selecting environmentally friendly finishes, stains, or sealers, facility teams should prioritize manufacturers that have achieved Greenguard certification. This certification ensures the product meets stringent chemical emissions standards and contributes to healthier indoor air quality.
