Bona Mega surface preparation

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.

• Floors that have been previously treated with wax, polish or similar products cannot be overcoated with Bona Mega
• Bona will not guarantee good adhesion when overcoating finishes of a brand other than Bona.
• Apply Bonakemi Mega to a small test area to confirm performance and compatibility.

Before application, ensure contents is shaken thoroughly. 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 of this product.

Bona Mega on previously finished flooring

With an addition of 2% Bona Crosslinker, Bona Mega will normally have very good adhesion properties on pre-finished flooring, it is advisable however 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.

Preparation of factory pre-finished floors

Prior to application of Bona Mega to factory pre-finished floors, the flooring must be treated with the Bona Prep system in accordance with instructions on the container label.

Preparation of previously finished flooring

As with factory pre-finished flooring, previously finished floors must also 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 1-2 coats of Bona Mega with the addition of 2% Bona Crosslinker.

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