It's worth knowing which of these two jobs a product does before buying, since using a tone-effect primer where a bonding primer is needed (or the reverse) won't give the result you're expecting.
Bonding Primers
A bonding primer — such as Bona Classic, Bona Classic UX, Loba EasyPrime, Loba PrimaSeal Plus or Junckers SB Primer — is applied to bare or freshly sanded wood before the topcoat goes on. Its job is largely invisible: improving adhesion, reducing the risk of the finish "side-bonding" between boards, and keeping grain raise to a minimum so the final coat goes on smoothly. These are typically matched to a specific brand's finishing system — a Bona primer under a Bona lacquer, a Loba primer under a Lobadur finish — so it's worth checking compatibility before mixing brands.
Colour and Tone-Effect Primers
A separate group of primers exist specifically to change the tone of the wood before sealing, rather than just to improve bonding. Bona's White Primer and Junckers' WB Primer range create a whitewashed effect, with the final level of whiteness controlled by how many coats are applied. Bona Natural Primer does the opposite job — preserving the wood's untreated appearance under a durable topcoat. Bona Amber Primer and Bona Rich Tone push the other way, adding a warm amber cast or a darker, smoked-oak-style tone respectively. All of these are designed to be sealed afterwards with a compatible lacquer or oil rather than left as a standalone finish.
Gap Filling and Levelling
Bona Gel does a slightly different job to the primers above — it's a high-viscosity, trowel-applied product used either on bare wood or between coats of finish to fill small surface irregularities and reduce visible abrasion scratches, giving a flatter base for the topcoat.
Brand-Specific Maintenance Treatments
Several products in this range are tied to a specific flooring brand rather than being universal. Elka's Oiled and Lacquered Finish Protectors, along with its Scuff Mark Remover and all-purpose cleaners, are formulated for Elka-finished floors specifically, and Quickstep's Maintenance Oils are intended for the upkeep of Quick-Step parquet. Using a brand-specific treatment on a different manufacturer's floor isn't guaranteed to give the same result, so it's worth checking the floor's original finish before choosing one of these.
Common Questions About Primers and Treatments
Do I always need a primer before applying a lacquer or oil?
Not always, but it's common practice on bare or freshly sanded wood to improve adhesion and reduce grain raise. Some hardwax oils and one-coat systems are designed to work without a separate primer — check the specific product's instructions.
What's the difference between a bonding primer and a whitewash primer?
A bonding primer's main job is adhesion and preparation, with minimal visual effect. A whitewash or tone-effect primer is chosen specifically to change the colour of the wood before it's sealed.
Can I mix primer and lacquer brands?
It's generally best avoided. Primers are usually formulated and tested to work with that same manufacturer's topcoats, so mixing brands can affect adhesion or the final appearance.
Are Elka and Quickstep treatments only for their own flooring?
Yes — these are formulated specifically for their own finished flooring ranges and aren't guaranteed to perform the same way on a different manufacturer's floor.
