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

Previously waxed, polished or oiled floors cannot be overcoated with Bona Mega varnish unless sanded back to bare wood. Bona will not guarantee adhesion when over-coating non-Bona varnishes. Freshly sanded floors must be free of all dust, dirt and other surface contaminates.

  • Sand floors back to bare wood
  • Final sanding should be done with a fine sanding disk, screen or good quality sandpaper with a sanding grit of 120
  • Use a vacuum cleaner to remove all traces of sanding dust from the area to be varnished
  • For filling gaps between floor boards and skirting boards, use Bona Gap Master
  • For filing holes, splits, dents and other surface imperfections, use Bona Mix and Fill

Wood Floor Primers

For application to bare wood floors we recommend using a wood primer. This reduces the recommended number of varnish coats from 3 to 2 and can be more cost effective over large areas. Primers help with adhesion between the varnish and floor and can help with the colouration of the final finish.

Product Use
Bona Classic Primer A ready-to-use primer for use with the Bona range of varnishes
Bona Natural Primer Designed to preserve the impression of raw, untreated wood and commonly used with Bona Mega Natural floor varnish
Bona Intense Primer A 100% polyurethane based primer for practically all types of wood and especially on dense, oily, tropical hardwoods
Bona White Primer A high quality wood primer that creates a 'white-washed' effect on wood flooring
Bona Amber Primer Wood primer for oak and darker tropical species of wood. GreenGuard approved

Always do a test area before starting any project to check product suitability and compatibility. Shake well before use. Ensure room temperature does not fall below 13℃ during application and drying. Thoroughly read and follow the manufacturer's instructions on the container at all times.

  1. Apply thinly with a brush, roller or floor applicator
  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 the next coat. 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

Where a longer drying time is required due to high temperature and/or low humidity, Bona Retarder can be added to the varnish to increase the 'open time' of the product.

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.

Great varnish by Guy Slaney

I had a small patch of parquet flooring that was unvarnished and wanted to apply a layer of protection quickly and without too much fuss (or impact on the cats!). This did the job brilliantly the only problem is now I want to sand and re-varnish the rest of the floor!

Its the second time I have used the product - for our church hall. It's expensive - well it is for a church hall where money is at a premium. However the result makes the expenditure worthwhile. certainly receiving wow comments from users of the hall.

Excellent Easy to apply and gave a really hard finish by Judy Owen

the best product I have come across. I have used most of the other products on the market and found this really easy to apply with a good roller and am very pleased with the result. there was virtually no odour and it was easy to clean off the roller and brushes. I have already recommended it to friends.

Only floor varnish worth using by Mark Fox

Having used Mega for years it's the only floor varnish worth using. Gives a perfect finish, enhances the colour like spirit based, but with the ease of water based. I use a fibre applicator which I find better than brush or roller( see YouTube demos). Very durable & dries fast enough not to disrupt the area for days

Pretty good by Kevin Thompson

This is a water based polyurethane varnish. It is easy and quick to apply with a roller, and dries within a few hours-important on a floor, especially a hallway where I used it. I put on three coats. The only point I would make is that it sometimes had a milky appearance when wet, but this was not apparent once dried. Also, it needs sanding in between coats if you leave it more than 24 hours. It is only available in 5litre tins, which is more than I needed, and was quite expensive. So far, (three weeks) it has worn well. It onl
