Previously waxed, polished or oiled floors cannot be overcoated with Bona Mega Varnish unless sanded back to bare wood. Floors to be varnished must be clean, dry and free of all dust, dirt and other surface contaminates.

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

Wood Floor Primers

For application to bare wood floors we recommend using a wood primer. Primers help with adhesion between the varnish and floor and can help with the colouration of the final finish. Bona Mega is compatible with the following primers:

Please note: The use of Bona White Primer or Bona Natural Primer is not recommended for this product as the natural ingredients in Bona Mega will yellow the final finish.

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

The following applicators are recommended for application of Bona Mega:

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, lightly sand or denib using a screen or the Bona Scrad System, grit P150 or finer before applying the final coat

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.

Wooden floors should never be saturated with water as part of a cleaning routine as this will significantly reduce longevity and performance of the finish. Never use household cleaners / detergents as these may degrade or damage the finish

Regular Cleaning

For optimal performance, floors coated with Bona Mega will benefit from being cleaned with one of their floor mops and specifically formulated, pH balanced wood floor cleaners.

Bona Mega Renovation

Floors treated with Bona Mega that have become dull or tired looking over time can be restored with the following products.

No, The Bona Mega contains a small amount of linseed oil which tends to slightly yellow a primer that contains white pigment. The Bona Classic UX Primer is recommended instead.

This product covers up to 10m² per litre, per coat. A 1L container of Bona Mega typically covers around 5.5 m² for two coats. However, this can vary slightly depending on the application method.
