Easy to use and highly resistant to scratches, scuff marks and wear, it's easy to see why the Bona Mega product is a popular choice with DIY enthusiasts, hardwood flooring specialists and shop fitters alike.

  • Water- based so safe, quick & easy to use
  • Can be applied with a roller, brush or floor applicator
  • Highly resistant to wear, scuff marks & scratches
  • Bona Mega has very good chemical resistance

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 Bonakemi 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

Ensure contents is shaken thoroughly and always apply to a test area first. Bona Mega is best applied in thin coats with a roller in a smooth flowing action and avoiding any excess. Ensure room temperature does not fall below 13C during application and drying.

Application to pre-finished flooring
Ideally floors should be treated in accordance with the instructions on the label. A sanding disc/screen or paper with a sandpaper grit of 150 should also be used.

To check intercoat adhesion, apply a coat of Bona Mega to a small test area as described above i.e. sanded and clean, allow the coating to set for 3 days then scratch the treated floor surface gently with a coin. If the Bona Mega finish stays firmly attached to the test area, the adhesion is satisfactory.

Always thoroughly read the manufacturers guidance and instructions on the container or tin including any mixing and usage instructions on associated products.

Floors coated with Bona Mega can be easily cleaned and maintained with the Bona Floor Cleaning Kit or Bona Spray Mop.

For the best results, use Bona Floor Cleaner Spray or a damp mop. Never saturate wooden floors with water.

To restore the appearance of a dull floor use Bona Freshen Up from time to time. 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.

Bona Mega should be stored in a place where the temperature does not fall below 5℃ or exceed 25℃

Drying times may vary depending on room temperature and humidity - As a guide, In areas with a temperature of 20℃ and a humidity of 60%, allow 3 hours drying time between coats.

Floors will be ready for light foot traffic approximately 8 hours after the final coat has been applied. Bona Mega Varnish is fully cured in approximately a week and can then be cleaned using a damp cloth or mop with an appropriate floor cleaner. Rugs and carpet runners can also be laid after a week.

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

excellent even though a little pricey!

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.

Great finish by Chris Cronin

I have used bona mega for17years now, it's the best product on the market for domestic use. I have tried all the cheaper products and although some are very good like junkers I always go back to bona it's worth that bit extra

Easily applied by brush to a parquet floor fully belt sanded followed by 4 coats of Bona by John Whitaker

Beautiful rich satin finish from the matt Bona. Left it three weeks to harden while we went off to Spain. Ordered 5pm, received next morning, amazing. Helpful web site for a skilled first timer at re- varnish.

Great product by Will Johnson

I've used Bona Mega for a few years now with no problems. It's easy to apply and drys fast. In good conditions you can get three coats on in a day. I think the best thing about it, is that it keeps the flooring light in colour and it's really tough.

Great matt, non-yellowing wood finish by Andrew Watts

Very happy with this product. Having (unfortunately) used a supposedly non-yellowing varnish from a high street vendor for another room i'm glad i spent more time researching and spent a bit more money to get the finish I was looking for. Very similar colour and tones to the natural state of the wood gives our floorboards the rustic yet clean look we were trying to achieve.

Easy peasy, great results by Rebecca H Griffiths

I loved this product, the silk matt finish worked out well. I was concerned that it would be too shiny and had intended to order matt. Felt calling it satin might have been less confusing. The finish was nice though.

Great Quality Varnish by Ian Hawes

This product is great, goes on well, dries fast and if applied well gives a good even coat. I was varnishing a 13 x 11m room and it took just over 1 hour with the 10'' Padco applicator I used less varnish than expected so did 4 coats onto bear wood rather than 3 with each coat 90 deg to itself and at the end it looked amazing. Pity it has to get walked on! Time will tell how hard wearing it is.
