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 with Bona Prep system in accordance with the instructions on the label. A sanding disc/screen or paper with a sandpaper grit of 150 should also be used. Apply the initial coat of Bona Mega with Bona Crosslinker.

With the Mega/Crosslinker mix, Bona Mega will normally have very good adhesion properties, however it is advisable to check the intercoat adhesion prior to overcoating. 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.

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.

Came highly recommended by Lilian Mains

Good quality. Ideal for the floors. Looks good and I've been recommended that this product is hard wearing for our self catering cabin.

Easy peasy and looks amazing ! by Bev D

We moved into a house with a 1967 parquet floor with the original coating as they had put carpet over it. It has come up lighter (which is what we wanted) and looks like brand new ! We used a roller on a pole and a brush to do the edges. It took two of us inside of an hour to coat 2 rooms (40 sq m). The first layer we put on top of primer and it was not as easy so see where you had coated as the subsequent layers where it was sanded first. The finished floor looks like brand new and is beautiful. We had organised to stay with a neighbour for the night, but found it dried so quickly and once dry had hardly any smell so that, had we done the top layer earlier, we could have stayed at home! Thank you Bona.

Easy to apply, great finish by Charlie Hedgecock

Product was easy to apply, dried quickly and resulted in a finish exactly as advertised. Time will tell if the scratch resistance lasts.

Excellent by Andy C

Great product, coverage exactly as described. Instructions state that the wood primer is essential but I have just used 3 coats if varnish instead. Floor looks great, would definitely use again.

Very impressive product by Richard Taylor

For a water based varnish it produced a very touch texture which really brought out a rich finish to my oak block floor. Being water based, short drying times add it easy to complete in no time.

Great finish by Pablo Rimoldi

I strongly recommend this product. It hardly changes the look of the timber. I applied it on to a pine timber floor after it was sanded. I was difficult to spot the difference between treated and untreated timber.

A quality product! by Paul Martin

Had this product applied a few years ago when our parquet flooring was cleaned up and was very impressed. However, now that I'm now doing it myself the finish seems even better! A quality product. I suppose you get what you pay for!!

Great product by Robert Robertson

Great product, easy to use, applied 3 coats with a paintbrush. Did not use primer. Matt finish has very slight sheen which I liked .

As described by Anne

Our first experience sanding and varnishing floors. Really thrilled with the finish. Love that the character of the boards is still there, just enhanced by the varnish.

Easy coverage, nice finish by Chris Mighall

Bought this for old floorboards that had a bit of worm damage. Came quickly , and was easy to roller on. Found that after the third coat the floor started to feel rough to the touch so contacted Woodfinishes direct who recommended sanding over the floor with a 240/320 grade paper before a final coat, to take out the slight roughness, makes sense to me that this will work and apart from the bit of roughness I'm more than happy with the finish, and the companies overall standard

Lovely low sheen finish by MC

Very pleased with the finish. Easy to use and holding up well. However, very glad I bought the primer as well as it says in the instructions that three coats of the varnish instead of primer and two coats is not appropriate for pine floors.
