Bona ClassicSeal is a clear, water-based sanding sealer that protects hardwood floors by minimizing grain raise and tannin bleed. It creates a smooth base layer for all Bona waterborne finishes, ensuring an even application without deep wood penetration. VOC compliant and GREENGUARD Certified®, it covers 500–600 sq. ft. per gallon. Apply with recommended pads, allow 2–3 hours to dry before recoating, and avoid traffic until fully cured in 7 days. Clean tools with water and store properly for best results.
