- Hardwood floors
- Light and whitewashed wood
- Low odor jobs
A professional-grade waterborne floor finish that dries fast, cleans up with water, and stays water-clear, which makes it the finish of choice for light, whitewashed, or gray hardwoods where oil poly would yellow. It is low-odor and covers more per gallon than oil, though it lends less warmth to traditional oak and needs about a week to fully cure before heavy use.
Pros
- Stays crystal clear and non-yellowing, which is ideal over maple, ash, and whitewashed or gray floors
- Waterborne and low-odor (150 g/L VOC, GREENGUARD certified), so it is far more pleasant to apply indoors
- Dries in 2-3 hours between coats and covers more area per gallon than oil-based floor poly
Cons
- Adds a subtler warmth than oil poly, so traditional oak looks slightly cooler and flatter
- Costs more than big-box oil polyurethane and is often sold through flooring suppliers rather than every store
- Full cure takes about a week, so furniture and rugs must stay off longer even though it dries to touch fast

Frequently Asked Questions
- Will Bona Mega yellow over a light floor?
- No — it stays crystal clear and non-yellowing, which is exactly why it gets specified over maple, ash and whitewashed or gray floors where oil poly would warm the tone.
- How fast can you recoat a floor with it?
- 2-3 hours between coats, and it covers 500-600 sq ft per gallon — more per gallon than oil-based floor poly. Full cure still takes about a week, so furniture and rugs must stay off longer than the dry time suggests.
- Does it look as rich as oil-based polyurethane?
- Not quite. It adds subtler warmth, so traditional oak reads slightly cooler and flatter than under an oil finish. That is a preference call, not a defect.
