A lacquered wood floor that has lost its sheen but has not yet worn through to bare wood does not necessarily require a full sand and refinish. In many cases, a properly prepared and applied refresh coat can restore the appearance of the floor and extend the life of the existing finish by several years. Understanding when a refresh is appropriate, and how to do it correctly, saves both time and cost.
This guide explains the difference between a floor that can be refreshed and one that genuinely needs a full refinish, covers the process for refreshing a lacquered floor properly, and identifies the products best suited to the job.
When Can a Floor Be Refreshed?
A refresh coat is suitable when the lacquer finish is dull, scratched or slightly worn but the existing finish is still present across the whole floor. The key test is whether you can see or feel bare wood anywhere on the surface. If the lacquer has worn through in any areas, particularly in the most-used traffic paths, a top coat applied directly over those areas will not adhere properly and will peel. In those cases, a full sand and refinish is needed.
A floor that is simply dull from cleaning residue, surface scratches from grit, or UV discolouration of the lacquer surface is a good candidate for a refresh. So is a floor where the sheen has become uneven across the area from different rates of wear or inconsistent cleaning. If the lacquer film is intact, a refresh coat can restore uniformity.
Preparing the Floor for a Refresh
Preparation is the critical factor that determines whether a refresh coat adheres well or fails. The existing lacquer surface must be cleaned to remove all wax, polish, grease and cleaning product residue. Many commercially available floor polishes and spray cleaners leave a film on the surface that prevents fresh lacquer from bonding. Using the wrong cleaning product in the weeks before a refresh can mean the new coat peels away within days.
Clean the floor thoroughly with Bona Cleaner or an equivalent pH-neutral floor cleaner, then degrease the surface with a sugar soap or a dedicated lacquer adhesion promoter. Allow the floor to dry completely. Any wax or polish residue that cannot be removed by cleaning needs to be physically abraded away. This leads to the next step.
Screen the floor with a 120-grit or 150-grit abrasive screen using a buffer machine, or manually using a pole sander on smaller areas. This removes the gloss from the existing lacquer and creates a mechanical key for the fresh coat. After screening, vacuum and wipe the floor thoroughly to remove all abraded material before applying the refresh coat.
Choosing the Refresh Product
Bona Freshen Up is a specifically formulated single-component water-based lacquer designed for refreshing existing lacquered floors. It is designed to be applied directly over a properly prepared existing lacquer surface in a single coat and produces a consistent satin finish. It is not a full lacquer system and does not replace the film build of a multi-coat application, but it is very effective for restoring the appearance of a lightly worn floor.
If the existing finish is a Bona Traffic HD or similar high-performance two-component lacquer, applying a fresh coat of the same product (properly mixed) over a screened and cleaned surface can also work well. The important thing is that the existing finish system and the fresh coat must be compatible. Applying a two-component lacquer over a single-component one, or vice versa, can cause adhesion problems.
Application
Apply the refresh coat using a high-quality T-bar applicator or a lint-free application pad. Work in sections, moving with the grain direction and maintaining a wet edge to avoid visible lap marks. Apply a single even coat across the whole floor. Avoid going back over areas that have already started to dry, as this will mark the surface.
Allow the refresh coat to dry fully before allowing foot traffic, typically a minimum of 12 hours for a water-based product. Furniture should not be moved back for at least 24 to 48 hours. Avoid washing the floor for the first five to seven days while the lacquer cures to its final hardness.
When Refreshing Is Not Enough
- Bare wood visible in traffic paths: full sand and refinish required
- Lacquer peeling or flaking: adhesion failure, full refinish needed
- Deep scratches through to the wood: cannot be covered with a refresh coat
- Grey or black staining in the wood: water damage, requires sanding out
- Wax or polish that cannot be removed: may prevent adhesion of a refresh coat
A well-executed refresh coat on a properly prepared floor looks genuinely good and will not be distinguishable from a full refinish by most people who did not see the floor before. It is a practical and cost-effective maintenance option for floors that are not damaged but have simply lost their appearance. Used as part of a regular maintenance cycle every five to seven years, it can keep a lacquered floor looking well for many decades without requiring a full professional resand.
