MEGA ™ was developed utilizing “BonaTech,” Bona's advanced technology waterborne manufacturing process. MEGA is the world's leading waterborne finish, providing exceptional durability, beauty and value.

NOTE: MEGA finish will appear slightly amber on white, bleached or pastel floors. Always prepare a sample or test area to determine actual appearance. For a colorless finish on these types of floors, use Bona Strong™, Bona Traffic®, or Bona® Eon 70 brand floor finish. Use directly from container. Do not thin. Non-photochemically reactive (Not an ozone precursor). KEEP FROM FREEZING.


1. Be sure floor is free from wax or oily residue. 2. Use Bona Prep™ system (see label for directions). 3. Apply 1-2 coats of Bona Mega® (see finish directions).

NOTE: Mega will adhere to most stains and finishes after proper preparation and dry times. Stain, sealer and finish results may vary widely depending on the wood species, especially on oily and resinous “exotics”. ALWAYS PREPARE A SAMPLE OR TEST AREA TO DETERMINE COMPATIBILITY AND DESIRED RESULTS.

If Recoating a Factory Prefinished Floor, DO NOT USE Bona Mega®. Use only Bona Traffic® or Bona StrongTM finishes with the Bona PrepTM system.


1. Sand and prepare floor using NOFMA-accepted methods. 2. For a stained floor, make your final cut with 80-grit paper and screen with 80 - 100-grit screen. Apply Bona® DriFast™ Stain. For an unstained floor, make your final cut with 80 - 100-grit paper and disc to 120 - 150 grit. This burnishing will reduce the amount of grain raise. 3. Use Tampico Brush on buffer and vacuum thoroughly. 4. Tack with a dry Bona® microfiber mop or cloth. 5. Apply sealer and finish system (see finish directions).
THE MEGA SYSTEM IS A 3-COAT SYSTEM: 1 coat Bonaseal® (the use of Bonaseal® minimizes the possibility of sidebonding and tannin bleed) and 2 coats of Mega. Adding a third coat of finish is recommended in heavy-traffic commercial and residential areas.
NOTE: Use a clean applicator for sealer and a separate clean applicator for finish.

Abrading between waterbased sealer and finish coats is not necessary for adhesion unless it has been more than 48 hours since the previous coat was applied. Abrade solvent based sealer with a Bona Conditioning Pad before applying finish coats. For smoothest results, abrade all sealer coats with a Bona Conditioning Pad and 1-2 Delta Sheets to eliminate excess grain raise. Abrade prior to the final finish coat with just the Bona® Conditioning Pad. Always vacuum and tack thoroughly with a slightly water-dampened Bona® microfiber mop or cloth after abrading.


SHAKE WELL BEFORE USING. 1. Pour a 4" wide line of the finish along the starting wall. Go with the grain of the wood. 2. Using a clean, pre-dampened applicator, draw the applicator forward, with the grain of the wood, moving the finish toward the opposite wall. Holding the applicator at a "snowplow" angle will maintain a wet edge at all times. 3. At the end of each run, turn the applicator toward you and pad out the applicator parallel to the wet edge. 4. Feather out all turns. If pushed too hard or too fast, drips will fly off the applicator. 5. Missed areas can be touched up if seen right away. 6. To prevent lapping and dry marks, be sure you are using the recommended coverage of 500-600 sq. ft. per gallon. Be careful not to spread the finish too thin. 7. Allow your first coat to dry 2-3 hours. High humidity and/or low temperature conditions will extend dry time, while increased ventilation and airflow will reduce dry time (recommended conditions of 65-80°F/40-60% relative humidity). Always vacuum and tack thoroughly with a slightly water-dampened Bona® microfiber mop or cloth after abrading. Allow final coat to dry at least 48 hours before use.


The curing process takes approximately 7 days. Do not replace area rugs until the floor has fully cured. The floor may be walked on after 24 hours, but the floor is susceptible to scuffing or marring prior to completion of the curing time. Do not use cleaner during this 7 day curing time. Use only a dry Bona® microfiber mop or cloth for cleaning during the first week.


Tools should be cleaned with water and stored in the Bona® Applicator Storage Canister.


Put walk-off mats at all entrance doorways to keep out excessive dirt and grit. Sweep or vacuum daily and damp wipe as needed with Bona® Swedish Formula® Hardwood Floor Cleaner. {/tabs}
