Floor Sanding Before or After a New Kitchen renovation?

The Ultimate Sequencing Guide

When renovating a kitchen in a home with timber floors, one of the most critical decisions is the sequencing of trades. Homeowners frequently receive conflicting advice: should the floors be sanded and polished before the new kitchen goes in, or after?

Because cabinet makers are often driving the project timeline, their preference usually dominates. Their natural priority is a fast, uninterrupted kitchen installation. However, what is convenient for the cabinet maker does not necessarily produce the best structural, aesthetic, or long-term outcome for your timber floors or the finished renovation.

For the highest quality result, the optimal sequence is uncompromising: remove the old kitchen, completely sand and finish the exposed floors, and only then install the new cabinetry.

The Advantages of the Recommended Sequence

By stripping the room back to a blank canvas and fully finishing the floors first, you eliminate a host of structural and cosmetic risks. First, there is zero chance of heavy floor sanding machinery or wet coatings damaging your brand-new kitchen panels.

Second, as specialists in Floor Sanding Brisbane, we ensure the entire exposed timber floor can be leveled and made perfectly flat before the new cabinetry arrives. When the base cabinets are eventually fixed in place, they sit flush on a properly prepared, even floor rather than riding high on uneven, cupped, or bowed boards. This precise leveling prevents unsightly gaps beneath the new kickboards where water, swept debris, or vermin can easily penetrate and accumulate over time.

Furthermore, completely sealing the timber means every accessible part of the floor is protected before the kitchen permanently covers sections of it, ensuring the structural integrity of the wood beneath your expensive new cabinetry.

The Island Bench Risk

To understand why a fully finished floor is vital before installation, consider the practical reality of island benches. It is very common for an island base to be secured to the floor before the stone benchtop arrives. If the stonemason subsequently discovers there is insufficient clearance, or if the homeowner simply wants to shift the island’s footprint by a few centimeters, the base must be moved.

If the floor underneath was never sanded and coated, shifting that island instantly exposes raw, unfinished timber. Fixing this is not a quick touch-up. It requires substantial rework, additional expense, and massive project delays. In a worst-case scenario, the entire flooring job may need to be redone to achieve a consistent, seamless finish. Completing the floor first entirely removes this costly sequencing risk.

Why Cabinet Makers Fight This Sequence (And Why They No Longer Need To)

If doing the floors first is the best method, why do so many cabinet makers push back? The answer is scheduling and money.

Traditionally, floor sanders use standard water-based polyurethanes that take weeks to fully cure. Cabinet makers know that if the floors are done first, their own installation schedule will be severely delayed. They fear the newly coated floor will be soft, easily scratched, and require their tradesmen to tiptoe around in socks for days on end.

With older chemical systems, their fears were justified. But with the introduction of instant UV-cured polyurethane, those delays are completely eliminated.

At Floor Pty Ltd, we utilize a UV Rush curing system that allows for a seamless, zero-delay transition between trades. A standard schedule looks like this: the kitchen demolition team spends all week pulling out the old kitchen, finishing on Thursday. We arrive on Friday to completely sand and level the exposed floor. We apply two base coats on Saturday, execute the first UV cure on Sunday morning, apply the final UV Rush coat, and complete the final cure by Sunday afternoon.

The floor is instantly rock-hard, fully cured, and ready for maximum commercial-grade traffic that same Sunday afternoon. When the cabinet makers arrive on Monday morning, the floor is pristine, completely protected, and requires no tiptoeing. They lose absolutely zero time, their schedule is uninterrupted, and the homeowner gets the perfect sequence.

The Danger of “Compromise” Sequences

Many contractors will suggest alternative sequences to try and keep everyone happy. As an experienced floor sanding professional, I strongly advise homeowners to understand the severe drawbacks of these compromises.

Installing the Kitchen First, Sanding the Floors Second This is the most common alternative, and it is vastly inferior. Sanding around brand-new, expensive cabinetry is highly difficult and introduces immense risk. Edging machines working tightly against new panels can easily leave small sanding marks or scuffs near the base. If you are forced into this sequence by circumstances, you must insist, at an absolute minimum, that the cabinet makers leave the kickboards off until the floor work is completely finished to provide better access and minimize damage.

Sanding First, Installing the Kitchen, Finishing Later This sounds like an intelligent compromise, but it is a trap. If you sand the timber flat, leave it raw, and let trades walk all over it to install a kitchen, the prepared timber acts as a sponge for dirt, grit, and contamination. By the time the kitchen is in, the floor will likely need to be completely re-sanded before it can safely accept a coating.

The Two-Coat Compromise and the “Ghosting” Trap Some contractors suggest sanding and applying two coats of finish, letting the cabinet makers install the kitchen, and then returning weeks later to apply the final coat.

This is the most dangerous sequence for the long-term appearance of your floor. Trades working over a partially finished, uncured coating system will inevitably introduce microscopic contamination—sweat, chemical residue, and boot prints. When the floor sander returns to apply the final coat, that contamination gets permanently sealed between the layers of polyurethane.

This creates a chemical reaction known as ghosting. You may not see it immediately, but 18 months to two years later, pale or white boot-print-like marks—known as ghost footprints—will slowly appear under the surface of the floor. For a deeper explanation of how this chemical failure occurs, read our detailed guide on ghosting and delayed footprint marks. Splitting the coating process around a kitchen installation drastically increases the risk of this permanent defect.

The Final Verdict

Do not let the convenience of a single trade dictate the quality and longevity of your entire renovation. To achieve a perfectly flat foundation, protect your cabinetry, and ensure a flawless finish, the rule is simple:

Remove the old kitchen, completely sand and finish the timber floors using a rapid UV-cured system, and then install the new kitchen on a rock-hard, fully protected surface. If circumstances absolutely force the kitchen to go in first, leaving the kickboards off until the flooring is complete is your only viable fallback.
