Detailed Explanation
What a site-finished floor actually is
Site-finished (sometimes called site-sanded) hardwood is raw, unfinished wood installed directly to the sub-floor and then sanded flat, stained (if desired), and sealed in place by a finishing crew. Every plank meets its neighbour as one continuous plane — there are no factory bevels, no pre-applied UV cured topcoats, and no chamfered edges catching dust.
Prefinished hardwood, by contrast, arrives at site already sanded, stained, and coated in a factory. It installs faster and is ready to walk on the same day, but every board carries a small bevelled edge and the finish system is fixed at the factory.
The seamless surface
The single most distinguishing visual quality of a site-finished floor is the absence of micro-bevels. The floor reads as one continuous plane of wood rather than a series of individual boards. In open-concept spaces, wide-plank specifications, and high-design residential work, this difference is immediately visible and almost impossible to replicate with a factory product.
Unlimited stain and finish options
Because the floor is finished in place, the entire stain library from Loba, Bona, Duraseal, Rubio Monocoat, and other professional systems is available — and any one of them can be custom-blended to a colour the client has only seen in a photograph. There is no waiting on a factory run, no minimum order, and no settling for the closest sample in a binder.
The same flexibility applies to sheen (matte, satin, semi-gloss) and to the finish chemistry itself — waterborne polyurethane, oil-modified urethane, hardwax oil, or natural penetrating oil — each chosen to match how the client lives in the space.
Integrated staircases and transitions
When stairs, landings, and adjoining rooms are all finished at the same time with the same materials, the result is a stair system that reads as part of the floor rather than a separate component. Treads, risers, nosings, and stringers can all be stained and coated to match exactly, with no visible seam between floor and stair. This is one of the most common reasons architects and designers specify site-finished hardwood on premium residential projects.
A floor that can be renewed
A solid or thick-wear-layer engineered site-finished floor can be screen and recoated every 10–15 years to restore the finish without a full sand, and fully sanded and refinished multiple times across its life. The same floor can carry a family for fifty years, change colour once or twice along the way, and still be the original wood. Most prefinished factory finishes cannot be recoated without a full sand because the aluminium oxide topcoat resists adhesion.
When prefinished is the better answer
Site-finished is not always the right specification. Occupied renovations where minimal downtime is essential, tight project timelines, and certain commercial applications are often better served by a premium prefinished product. The point is not that one is universally better — it's that understanding when each system wins lets you specify with confidence rather than habit.
What to plan for on a site-finished project
Site finishing typically adds 5–10 days to the install schedule for sanding, staining, and curing. Other trades cannot be on the floor during this window, and the home or space needs to be empty.
After the final coat, light foot traffic is generally fine within 24–48 hours, area rugs and furniture should wait 5–7 days, and the finish reaches full cure at around 30 days. Planning the trade sequence around these windows is the single biggest factor in a successful site-finished project.
