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.

Very easy to use by Chris Walker

This is a wood floor sealer but I use it to seal stone floors and find it perfect

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.

Brilliant service, brilliant products by Chloe Ostmo

Varnish turned up very quickly and we are very very please with the result. Easy to apply and the finish is fantastic - it's matt and hasn't yellowed the wood.

EXCELLENT!!! by Karen Lewis

Used on freshly sanded old boards. After a thorough shake & the insertion which seemed to make the product pour smoothly without drips, dribbles or bubbles, this product was the easiest varnish to use. I have used other varnishes in the past & if it performs as well as others say, I will stick with it in the future too. Also the Matt finish has a slight sheen which is what I wanted.

Brilliant stuff by Gareth Heeley

Best filling option their is, mix with sawdust from the workpiece and fill away, you can fill large voids bigger than the 2mm limitation set by the instructions but its beat to do several applications in such cases. This stuff should be on the shelf of every workshop

Great product by Martin Harland

I was recommended to use this product by a proffessional. I found it easy to use, quick drying, and gave the professional, luxury finish I wanted. I also bought the applicator, which I would also reccommend. all in all, I am very satisfied with the product, and service from Wood Finishes Direct. I would not hesitate to use again.

Easy to use, no mess and professional finish by Eric Clark

Liked what I read on previous reviews for Bona Mega so gave it a try. Used it on my wooden stair treads made from 200 year old pine, after stripping off old paint and stain. Three coats so far and they look great. Been in constant use since last month and not a scratch visible.

This is an excellent product to use. Good open time, easy to lay down over a large area. My only issue is the quantity you have to buy.
