Priming a wood floor properly is what lets a lacquer or oil sit evenly and bond well — browse our range of primers, sealers and floor treatments from trusted UK suppliers, covering everything from bare-board prep to post-fit touch-ups.
Whether you're sealing bare boards for the first time or freshening up a lacquered floor that's picked up a few scuffs, the products above cover most of what a professional fitter would reach for.
Why Priming Matters Before You Lacquer or Oil a Floor
Bare or sanded wood absorbs finish unevenly — patchy areas, filled boards, and end grain all soak up more product than the surrounding timber. A primer or sealer coat evens out that absorbency so your top coats of finish go on more consistently and often in fewer coats. Which primer you need depends on the system going over it: water-based finishes generally call for a water-based primer, while traditional solvent-based lacquers typically need a matching solvent-based product underneath.
Water-Based Primers for Fast Turnarounds
For jobs where low odour and quick drying matter — occupied homes, tight schedules — water-based primers are the usual choice. Bona offers a broad range here, from the Bona Classic UX Primer down to a smaller 1L size, plus white and natural-toned versions for jobs where a specific undertone is wanted. Junckers offers its own line in three shades (clear, white, and Nordic), and Loba's water-based options — the EasyPrime and PrimaSeal Plus primers — are formulated to seal porous timber before a water-based top coat.
Solvent-Based Primer for Traditional Systems
Where a floor is being finished with a solvent-based lacquer, the Junckers SB Primer is the matching sealer — designed to work as part of a solvent-based build-up rather than under water-based coats.
Toning and Colour-Enhancing Primers
Some primers do double duty as light colour treatments, warming or adjusting the tone of the wood before lacquer goes on. Bona's Amber Primer adds warmth to pale timbers, while its Nordic Tone and Rich Tone primers sit at opposite ends of that scale — cooler and deeper respectively. The Bona Gel, 5L is worth a look too if you're also comparing wood dyes and stains for a more pronounced colour change.
Floor Treatments and Protectors for Ongoing Care
This category isn't only about prep — it also covers products for maintaining a finished floor. The Elka Lacquered Finish Protector helps extend the life of an existing lacquer coat, and the Elka Scuff Mark Remover is handy for lifting everyday marks without a full refinish. For general upkeep, there's the Elka All Purpose Cleaner for Wood Flooring and a concentrated version of the same product.
FAQs
Do I always need to prime a wood floor before lacquering?
Most sanded or bare wood floors benefit from a primer coat, since it evens out absorbency and helps the lacquer sit more consistently. Some pre-finished or lightly refreshed floors may not need one — check the guidance on the specific finish you're using.
Can I use a water-based primer under a solvent-based lacquer?
Generally, you should match the primer to the finish system — a water-based primer under a water-based lacquer, and a solvent-based primer like the Junckers SB Primer under a solvent-based one. Mixing systems can affect how well the coats bond.
What's the difference between a primer and a toning primer?
A standard primer mainly seals and evens out the wood before finishing. A toning primer, such as the Bona Amber Primer or Bona Nordic Tone, does that job while also subtly adjusting the colour of the timber.
How long should primer dry before applying the finish?
This varies by product and by site conditions such as temperature and ventilation. Always check the data sheet or product page for the specific primer you're using.
Are these treatments suitable for engineered and solid wood floors?
Most of the primers and treatments here are suitable for both, but always check the individual product listing, as some are formulated with a specific floor type or finish system in mind.
