ChemMaster Safe Cure and Seal 309 WB

ChemMaster Safe-Cure & Seal 309 WB, This water-based product will cure fresh concrete to ASTM C309 standards and protects concrete surfaces from the intrusion of water-borne contaminants and dirt. This product is a water emulsion, styrene acrylate copolymer curing and sealing compound for concrete. Safe-Cure® & Seal 309 is a low-odor product that produces a medium gloss film.


  • Effectively curing any fresh concrete enabling the concrete to reach its design strength, while minimizing drying shrinkage cracking
  • After curing is complete, the durable SAFE-CURE & SEAL 309 film will continue to protect the concrete from salt and water penetration
  • Sealing and dust proofing any older concrete surface
