What Is Floor Sanding & Refinishing?
Floor sanding and refinishing is the mechanical process of removing the top layer of an existing hardwood floor's finish and a thin layer of wood beneath it, using drum or orbital sanders progressing through finer grits until the surface is smooth and even. This is the technical process behind hardwood floor refinishing, focused specifically on the sanding equipment and technique involved. Abingdon, IL homeowners with older hardwood, especially in homes that haven't been refinished in a decade or more, rely on this service to remove deep scratches, discoloration, and an uneven, worn-out finish before new stain and protective coating is applied.
Why You Shouldn't Wait
Sanding hardwood is an unforgiving process, since removing too much material in one spot creates visible dips that are difficult to correct afterward. Using the wrong grit progression or moving too quickly through grits leaves swirl marks and an uneven surface that shows clearly once stain is applied, since stain highlights rather than hides sanding imperfections. Sanding against the wood grain, or with equipment that isn't properly maintained, can gouge the floor in ways that require replacing individual boards. Because each sanding removes a portion of the wood's limited wear layer permanently, doing it correctly the first time matters more than almost any other step in the refinishing process.
Our Process
Room Prep & Equipment Setup
Furniture, rugs, and trim are removed or protected, and dust containment barriers are set up around the sanding equipment before work begins.
Coarse Grit Sanding
A drum sander removes the old finish and top wear layer using a coarse grit, working carefully along the grain to avoid gouging the wood.
Medium Grit Pass
A medium grit follows to smooth out marks left by the coarse pass, progressively refining the surface toward an even, consistent texture.
Fine Grit & Edge Sanding
Fine grit sanding completes the main floor while an edge sander handles areas along walls that the drum sander can't reach directly.
Final Buffing
A screen or buffer pass removes any remaining fine scratches and dust, leaving a perfectly smooth surface ready for stain and finish coats.
What to Expect
Sanding typically takes one to two days depending on room size and how many passes the floor's condition requires. Expect significant noise during active sanding, and while our dust containment systems capture most debris, we recommend covering items in adjacent rooms as an extra precaution. The floor will need to be completely clear of furniture and rugs throughout the sanding process. Once sanding is complete, we move directly into staining and finishing, which adds additional days depending on how many coats your chosen finish requires and the drying time between each one.

Frequently Asked Questions
Typically a very thin layer, often less than a millimeter per pass, just enough to remove the old finish and surface imperfections without excessively thinning the board.
Most scratches sand out completely. Deep dents or gouges may still show a faint shadow since they compress the wood fibers rather than just marking the surface.
Our equipment includes dust containment systems that capture most debris at the source, though some fine dust is still expected with any sanding project.
Engineered hardwood can be sanded, but more carefully and fewer times, since its veneer layer is thinner than solid wood. We assess veneer thickness before starting.
Sanding and finishing typically happen as one continuous project, with finishing starting once sanding and dust cleanup are fully complete.
We check by examining the floor at a vent or transition point where the board's edge is visible, giving us a good estimate of remaining wear layer thickness.
