ChemMasters Safe-Cure & Seal 309, Water-Based Curing and Sealing Compound, 5-Gallon Bucket

ChemMasters Safe-Cure & Seal 309 is a water-emulsion, styrene-acrylic copolymer curing and sealing compound. Low-odor Safe-Cure & Seal 309 produces a medium-gloss film, cures fresh concrete to ASTM C309 standards, protects concrete surfaces from the intrusion of water-borne contaminants and dirt, and is a low-volatile organic compound (V.O.C.) water-based product.

• Very low VOC emissions at <100 g/L VOC
• Compatible with most resilient floor covering adhesives (conduct a small test patch to ensure compatibility)
• Protects concrete surfaces against deicing chemicals, fertilizers, salts, grease, oil, alkalies, mild acids, and detergents
• Minimizes spalling due to freeze-thaw cycle exposure, hair-line checking, premature cracking, dusting and other common defects that result from improperly cured concrete
• May be applied over existing water- and solvent-based sealers (conduct a small test patch to ensure compatibility)
• Seals out most construction dirt and stains
• Prevents mortar, plaster, and concrete droppings from bonding to concrete surfaces
• ASTM C309, Types 1 (Type 1D upon request), Class A and B, Standard Specification for Liquid Membrane Forming Compounds for Curing Concrete
• AASHTO M 148, Type 1 (Type 1D upon request), Class A and B
• 5-gallon bucket
