THE FINISH MATTERS AS MUCH AS THE WOOD: WHAT DESIGN PROFESSIONALS SHOULD KNOW

Introduction

When architects and designers specify hardwood flooring, most of the conversation centers on wood. Species selection, plank width, grain character, color — these are the decisions that

shape the visual experience of the floor and, by extension, the room.

What receives considerably less attention and deserves considerably more, is the finish.

The finish is the layer that contacts daily life. It is what shoes, furniture legs, pet claws, spilled

drinks, and cleaning products actually touch. It determines how the floor looks at year one, year five, and year fifteen. It affects maintenance requirements, sheen level, the feel of the wood underfoot, and how well the floor can be repaired or restored over time.

For design professionals who want to specify flooring that performs as well as it presents, finish literacy is essential. Here is what you need to know.

The Two Fundamental Approaches

Hardwood floor finishes fall into two broad categories: surface finishes, which form a protective coating on top of the wood, and penetrating finishes, which absorb into the wood fibers and harden from within. Each produces a distinctly different result in terms of appearance, feel, maintenance, and repair.

Surface finishes — polyurethane

Oil-based and water-based polyurethane are the most common surface finishes in residential hardwood flooring. Both create a durable protective layer on top of the wood, providing strong resistance to everyday wear, spills, and surface abrasion.

The most important difference between the two is how they affect the wood's appearance. Oil-based polyurethane imparts a warm amber tone that deepens and enriches over time a

characteristic that reads beautifully on traditional species and classic interior styles. Water-based polyurethane dries clear, preserving the wood's natural color more faithfully and lending itself to lighter, more contemporary aesthetics.

As Bona has documented, the durability gap between quality oil-based and water-based

polyurethanes has narrowed significantly with modern formulations. The choice today is less

about which is more durable and more about what appearance and maintenance profile best serves the design intent and the client's lifestyle.

Penetrating finishes — hardwax oil

Hardwax oil represents a fundamentally different philosophy. Rather than forming a coating on the surface, it penetrates the wood fibers and cures within them, creating a finish that is

essentially part of the wood itself rather than a layer sitting on top of it.

The result is a floor that looks and feels more natural and closer to unfinished wood in texture and warmth, with a depth of grain that surface finishes cannot replicate. For projects where the design intent is a raw, organic, or craft-forward aesthetic, hardwax oil delivers a result that polyurethane simply cannot match.

The trade-off is in maintenance. Because there is no surface film to protect the wood, spills

need to be addressed quickly, and spot repairs are handled differently than with a surface finish. The upside is that repairs are genuinely spot repairs — a scratched or worn area can be treated without affecting the rest of the floor, which is not the case with polyurethane.

Sheen Level Is a Design Decision

Within either finish category, sheen level. The degree of reflectivity the finish produces and has a significant impact on how a floor reads in a space. Matte and satin finishes absorb light and produce a quieter, more grounded look that tends to recede visually and allow the wood's natural character to lead. High-gloss finishes reflect light and create a more formal, polished appearance.

For most contemporary residential projects, lower sheen levels have become the predominant choice. They show less surface scratching, require less maintenance to keep looking clean, and align with the move toward natural, understated interiors that has defined premium residential design for the past decade.

Sheen level should be specified deliberately, not defaulted to. It is a design choice with real

consequences for how the floor ages and how much ongoing attention it requires from the

homeowner.

How Finish Affects What Happens Over Time

Refinishability

Surface-finished floors can be sanded and refinished, which removes the existing finish layer

and allows a new one to be applied. This is what allows a hardwood floor to be fully restored

rather than replaced and it is one of the primary reasons hardwood is such a strong long-term investment.

Penetrating finishes are refreshed rather than refinished. The process involves cleaning the

floor, lightly abrading the surface, and applying a maintenance coat of the same product. This is less disruptive and can often be done without vacating the home but it requires using compatible products and maintaining the floor according to its specific care requirements.

Maintenance implications for the homeowner

The finish you specify determines the maintenance protocol the homeowner will live with for years. A polyurethane finish is forgiving. It protects well against everyday spills and requires only regular cleaning with an appropriate product to maintain its appearance. A hardwax oil finish requires more attentive care but rewards that care with a floor that looks genuinely beautiful in a way that is difficult to achieve with a surface coating.

Setting accurate expectations with the homeowner before specification is part of delivering a result they will be satisfied with long after the project closes.

Matching Finish to Design Intent and Client Lifestyle

The most effective finish specification is the one that serves both the design intent and the

reality of how the client will live in the space. These two factors do not always point in the same direction, and navigating the tension between them is where professional guidance adds the most value.

A family with young children and pets who want the organic warmth of a hardwax oil floor needs to understand what that commitment requires before the floor goes in. A client who wants a high-gloss, formal finish in a high-traffic open floor plan needs to understand the maintenance implications of that choice. Getting the finish right means having that conversation early — which is exactly why Mansion Hill engages from the design phase rather than at the end of the project.

Mansion Hill Custom Floors as a finish resource

Finish selection is one of the areas where our team adds the most value to design-phase

collaboration. We work with architects and designers to match finish type, sheen level, and

application method to the specific design intent and lifestyle of each project — and we provide the technical knowledge to back those recommendations.

We also offer continuing education resources for design professionals through our partnership with the National Wood Flooring Association, covering finish systems, installation standards, and the technical considerations that produce the best long-term results.

If finish decisions are part of an upcoming project, we would welcome the conversation.
