Concrete Defoamer – 1 Pound | Heavy-Duty Anti-Foaming Agent for Cement, Mortar & Grout | Improves Mixing, Pumping & Surface Finish | Works in Hot/Cold Weather (Clear, 1 Pound)

Heavy-Duty Foam Control – Fast-acting concrete defoamer eliminates air bubbles and foam in cement, mortar, and grout mixes. Improves workability and surface finish by preventing voids and honeycombing in cured concrete.
Water-Based & Non-Silicone Formula – Safe for pumped concrete and precast applications—our non-silicone defoamer won’t interfere with adhesives or coatings. Low VOC and compatible with most admixtures.
All-Weather Performance – Works in hot or cold climates (-10°F to 120°F) to stabilize mixes for ready-mix trucks, shotcrete, and DIY projects. Reduces foam during high-speed mixing or pouring.
Easy to Use & Cost-Effective – Just 1-2 oz per 100 lbs of cement for optimal results. 1-gallon jug treats up to 6,400 lbs of mix—saves labor and material waste from foam-related defects.
Professional-Grade Results – Trusted by contractors for smoother finishes, stronger compressive strength, and reduced pinholes in stamped, polished, or structural concrete.
