Bona Sport® Seal – Professional Oil-Modified Sealer for Gym Floors

Bona Sport® Seal is a premium oil-modified polyurethane sealer designed specifically for newly sanded sport and multi-use hardwood floors. Ideal for basketball courts, gymnasiums, dance studios, and stages, it creates a uniform seal layer that enhances finish performance and prevents penetration into the wood.

It’s compatible with Bona Sport® Poly and Bona All Court® Poly, forming a complete, professional-grade finish system.
