Concrete & Stone Floor Sealers

The right sealer protects your floor and locks in the finish — whether you're sealing decorative concrete, a polished floor, or natural stone. We carry sealers and topcoats for every job: easy decorative sealers, tough industrial topcoats, and penetrating stone sealers. And we'll help you match the right one to your floor, your traffic, and your finish. Call and talk to a real surface-prep expert, not a call center.

Decorative & Polished Concrete Sealers

  • Smith's Poly-SEAL+ — fast-dry, one-component waterborne decorative sealer; easy to apply, gloss or low sheen
  • Smith's Poly-WB+ — two-component, high-performance waterborne aliphatic urethane topcoat; tough, durable, UV-stable

Which Sealer Do You Need?

  • Decorative concrete, lighter duty → Poly-SEAL+
  • Durable, UV-stable decorative topcoat → Poly-WB+
  • Heavy industrial / high-traffic → Hi-Wear 90S, CRU ’86, or Polyaspartic 5000LO
  • Natural stone → a Hertron sealer (Hetro-Seal, Alpha Seal, Zeta Seal, Bocci Seal, or H2O Seal)

Not sure which fits your project? Call us and we’ll help you choose the right protection.

Sealing vs. Topcoating

A sealer protects and enhances the surface; a topcoat adds a tougher, more durable wear layer for demanding conditions. For high-traffic or industrial floors, a urethane or polyaspartic topcoat gives you maximum protection. We’ll help you decide how much protection your floor needs.

Shipped Fresh, Factory-Direct

Our sealers and coatings ship factory-direct from the manufacturer to your job site — so you get fresh product, straight from the source, exactly when you need it. Tell us what you need and we’ll take care of the rest.
