Bona Mega on factory pre-finished & previously finished flooring

General conditions to determine if an overcoating of Bona Mega is possible

• Surfaces must be completely clean and free of all dust, dirt and other contaminates.
• Floors that have been previously treated with wax, polish or other similar products cannot be overcoated with Bona Mega
• Users are advised to test a small area prior to application to see weather Bona Mega will overcoat the area.

Bona will not guarantee good adhesion when overcoating finishes of a brand other than Bona.

With an addition of 2% Bona Cosslinker, 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.
