    Follow these recommendations to achieve the best application results for Bona Mega.

    TDS Application Notes

    1) Shake the lacquer thoroughly for one minute. 2) Apply using a Bona Roller at 8–10 m²/L (≈100–120 g/m²). Roll alternately across and with the grain of the wood avoiding accumulations of product. Always maintain a “wet edge” to avoid overlaps. 3) Allow to dry properly before applying further layers. Ensure proper ventilation. 4) If necessary, make an intermediate sanding using the Bona Scrad System P150 grit (or finer) and remove dust before applying a final layer of lacquer. Note: If the previous layer of lacquer/primer has been allowed more than 24 hours drying time then an intermediate sanding is always required. Light foot traffic can be resumed after 8 hours but the surface remains susceptible to scratching and marring until fully cured. Full cure is achieved after approximately 7 days. Do not cover or damp-mop the surface until fully cured.

Because of the wide range of possible uses and conditions of application of our products, we do not relieve users from the need to carry out their own trials or to seek technical advice from Bona before use.

    TDS Important

    • Plasticisers found in materials such as carpet underlays, furniture legs, castors and adhesives used for fixing can lead to softening and discolouration. Exposure to hair dyes or rubber tyres on cars, cycles and baby strollers can lead to permanent, irreversible discolouration of the surface. Use protection or completely avoid contact. • Spills should be removed promptly. Unattended spills may cause cosmetic stains or damage the surface. • Please note that whilst Bona lacquers are designed to provide a sealed surface that is resistant to wear, scuffing and spillage, etc. No surface applied finish system can prevent physical damage to the timber or “harden” the floor. Indentations in the wood and scratches may be caused by furniture, dropped items, dog claws, etc. and steps should be taken to reduce the possibility of this occurring. • Bona lacquers are non-yellowing and do not change colour due to the effects of UV light. However, Bona lacquers cannot prevent the wood itself changing colour due to tannin bleed, the movement of natural oils or the effects of UV light.

    TDS Main USP

    ONE COMPONENT, WATERBORNE COATING

    TDS Preparation

    Ensure floor is acclimatised to its end-use environment. The surface must be sanded back to bare wood, dry and free from sanding dust, oil, wax and other contamination. Surface should be pre-treated with a Bona primer prior to the application of Bona Mega. Allow lacquer to reach room temperature, insert filter and shake the container vigorously before use. Optimal conditions for use are between 18–25 °C and 30–60 % relative humidity. High temperatures and low humidity shorten, low temperatures and high humidity lengthen drying time. Minimum temperature for use is 13 °C.

    TDS Treatment Schedule

    Standard protocol untreated wood: 1 × Bona Primer ¹ Light sanding with 150 grit 2 × Bona Mega ¹ Bona Mega produces a subtle rich tone which is more noticeable on light wood species and on floors treated with a light stain or whitening primers. Overcoating Bona White primer with Bona Mega is not recommended if you are looking to achieve a true white look. Note: It is not recommended to apply more than two full coats of primer and/or lacquer per day due to risk of excessive wood swelling. Ensure good ventilation during drying. Poor drying conditions may reduce product performance and adhesion.
