Bona Mega varnish is a water-based PU varnish that forms part of Bona's Wood Floor Varnish range.

  • Surfaces should be sanded back to bare wood and be free of all sanding dust, grit, dirt, oil, wax and any other contaminates. The final sanding should be done with a fine sanding disk, screen or good quality sandpaper with a sanding grit of 120 or finer.
  • Previously waxed, polished or oiled floors cannot be overcoated with Bona Mega unless sanded back to bare wood. Bona will not guarantee adhesion when over-coating non-bona varnishes
  • Apply Bona Mega to a small test area to confirm performance and compatibility.
  • For application to bare floors, a coat of Bona Prime Classic reduces recommended number of coats to 2, otherwise 3 thin coats of Bona Mega is advised.

Always do a test area before starting any project to check suitability and compatibility. Shake well before use. Ensure room temperature does not fall below 13℃ during application and drying. Thoroughly read the manufacturers guidance and instructions on the container.

  1. Apply thinly with a roller.
  2. Start at the edges and then roll with a smooth flowing action alternately across and with the grain of the wood.
  3. Avoid accumulations of finish and overlap wet-in-wet without interruption.
  4. Allow to dry before applying another layer of finish. Anticipate slightly longer drying time for each layer that is applied.
  5. If necessary make an intermediate sanding using a screen or the Bona Scrad System grit P150 or finer before applying the final layer of finish.

Please Note: If the previous layer of finish has been allowed more than 24 hours drying time then an intermediate sanding is always required. The floor will take light foot traffic approximately 8 hours after the final application. Allow the surface to dry for at least 1 week before covering with carpets or other floor coverings, or loading with heavy objects. Also avoid damp mopping the floor until after this time.

Wooden floors treated with water-based varnishes should never be saturated with water as part of a cleaning routine as this will significantly reduce longevity of performance.

Regular Cleaning

For optimal performance, floors coated with Bona Mega will benefit from one of the appropriate Bona floor cleaners.


To restore the appearance of a dull floor use Bona Freshen Up. This will improve the appearance of the floor whilst still allowing further coats of Bona Mega to be applied at a later date without the need to sand the floor back to bare timber.

Easy to apply even for a first timer by Sarah Bolger

I had never varnished a floor before so spent a lot of time researching how and products. I chose bona mega extra Matt varnish and have not been disappointed. Initially did one room and lov d it so much I have since done the whole house. The boards look natural and extra Matt is super Matt which is what I wanted.

Great adhesion, easy to apply, looks good by Mr Leader

I have used this product for over 10 years and in my opinion it is the best on the market. It does not distort the colour of the wood.

Brilliant varnish by Jacky

I used this on a solid light oak parquet floor and it looks stunning. After 3 coats (1 to prime the floor, then a light sanding and 2 further coats) it has the very slightest sheen and hasn't coloured the floor at all, which is just what we wanted. It has had a few spillages on it and liquid just sits on top of it. I couldn't be more happy with it, definitely worth paying that bit extra to protect your beautiful new floor properly! I'll be buying more of this to finish off the rest of the flooring when it is laid.

Superb! by Mr D Russell

I've been using Bona varnishes for 15 years, and the sheer quality and versatility that they allow,when combined with non-solvent tints/ dyes to produce a beautiful floor finish, is wonderful!

Excellent product giving a professional finish by Mr. S. Harrison

Bona Mega varnish was easy to use, being a one part varnish, but gave as good a finish as 'professional' two part varnishes. I bought 10 litres for a room of 30m2 and it gave enough for 4 coats with enough left over to recoat another similar area twice. So the coverage was significantly better than advertised. I would never bother with cheaper DIY shop varnishes again.

Easy to paint on & drys very quickly with hard finish, compliments our distressed Oak finish floor perfectly by Andrew Choules

Fantastic by Nicola

We used this on our stained pine floor (manns pine stain) and the results are better than expected. The varnish enhances the wood and gives a nice sheen which isn't too glossy. Our floors look much more expensive than they were. Plus it was a doddle to apply. I used a varnish brush and left 3 hours between the 3 coats. I also got helpful advice from customer services regarding application.

Good product, relatively easy to use by Rod Hulse

Applied the Bona Mega silk matt varnish to a resanded hard wood floor - easy and quick to use applied with a roller and second coat with a microfiber cloth. Think that the best finish would come from a large paint pad. The finish is a bit more glossy than anticipated from a product that is billed as being Silk Matt.

Bona Mega (silk/matt) brought my Junckers flooring up a treat :-) by Justin Isbell

Our Junckers flooring was 10+ years old and thoroughly worn so we decided to renovate it ourselves to save some money. Wasn't sure where to start but the Wood Finishes Direct site had plenty of info to guide me... and lots of helpful reviews/comments for the product we chose: 2x 5L Bona Mega (in a silk/matt finish)... plus a 5% discount through QuidCo. Sanding the floors (conservatory, kitchen, hall and pantry) was hard work but the three coats have come up a treat... shiny but not glossy and looks fantastic. It was about 30m2 x3 coats and the product claimed coverage of 100m2 for the amount we bought... I'd say they were about right as we've got about 2L left. Anyway, I'll treat my floors a little kinder from now on (felt pads on chair feet etc.) and give the floor a light sand to key it, then a fresh coat on the well trodden areas every year or two. Very pleased as our floors are now transformed.
