Five Star Instant Grout is a rapid strength gain, non-metallic, non-shrink grout specifically engineered for supporting machinery requiring precision alignment and quick turnaround. Formulated with advanced Air Release technology, this high-performance grout excels in cold weather applications while providing exceptional reliability and consistent results. When tested in accordance with ASTM C827, Five Star Instant Grout exhibits positive expansion, meeting the rigorous performance requirements of ASTM C1107-02 Grades A, B and C, ASTM C1107/C1107M-20, and CRD-C 621-93 specifications for non-shrink grout.
This precision grout achieves an impressive 4,000 psi compressive strength in just 4 hours, with a 10-minute working time at 70°F that allows for efficient installation and rapid equipment return to service. Its superior formulation consistently delivers 95% Effective Bearing Area (EBA) when proper grouting procedures are followed, ensuring optimal load distribution and long-term structural integrity. The combination of rapid strength development and dimensional stability makes Five Star Instant Grout the preferred choice for contractors and engineers working on critical machinery installations where downtime must be minimized and precision maintained.

Frequently Asked Questions
What is the recommended placement depth for Five Star Instant Grout?
It is designed for placement depths between 1 inch and 3 inches. For pours over 3 inches, contact Five Star for specific guidelines and aggregate extension recommendations.
How long before equipment can be operated?
Under typical conditions at 70°F, the grout reaches 4,000 psi in 4 hours. In-service operation may begin immediately after the required grout strength has been reached.
What type of surface preparation is required?
Concrete surfaces should be prepared to coarse aggregate exposure with a minimum ½ inch peak to valley surface profile. Surfaces must be clean, free of oil, grease, and contaminants, and presoaked for a minimum of 8 hours to achieve Saturated Surface Dry (SSD) condition.
What is the mixing ratio and working time?
Mix with 3.0 to 3.5 quarts of potable water per 55 lb. bag. Working time is 10 minutes at 70°F, though this may be affected by colder and warmer temperatures.
What is the shelf life and storage requirements?
One year in original unopened packaging when stored in dry conditions. High relative humidity will reduce shelf life.
What is the maximum in-service temperature?
Five Star Instant Grout can withstand continuous service temperatures up to 400°F (204°C), making it suitable for high-temperature industrial applications.
