SikaQuick Set-45 – Very Rapid-Setting Magnesium Phosphate Repair Mortar (50 lb Bag)

SikaQuick Set-45 is a single-component, magnesium phosphate-based mortar engineered for high-speed repair of concrete structures in extreme conditions. Ideal for both interior and exterior repairs, this fast-setting mortar develops 2,000 psi compressive strength in just one hour and can be opened to rubber tire traffic in 45 minutes. Designed for use in ambient and substrate temperatures below 85°F, it offers excellent freeze/thaw resistance, very low drying shrinkage, and high bond strength without requiring wet curing. SikaQuick Set-45 is ideal for emergency repairs, cold weather applications, and rapid return-to-service concrete restoration projects where strength and durability cannot be compromised.
