Five Star LC Epoxy Grout is a high-performance, three-component epoxy system built for industrial installations that demand strength, precision, and reliability in tight clearances. Its 100% solids, non-shrink formula allows placement in spaces as narrow as 3/8 inch, where standard grouts often fail.
This grout gains strength quickly. It reaches 13,000 psi in just 24 hours and can achieve up to 17,000 psi with post-curing. As a result, it supports critical equipment with minimal downtime. Unlike many standard options, it handles dynamic and repetitive loading without losing dimensional stability.
LC Epoxy Grout bonds aggressively to both concrete and steel. It also resists chemicals commonly found in industrial and marine environments. Because of its high flow properties and 95% effective bearing area, it fills voids completely and provides full-contact support under baseplates, crane rails, conveyor systems, and rail tracks.
Ultimately, this formulation helps crews meet precision grouting specs on schedule — especially when space is limited and performance can’t be compromised.

Frequently Asked Questions
What is the minimum and maximum placement depth for Five Star LC Epoxy Grout?
You can place LC Epoxy Grout at a minimum depth of 3/8 inch. However, if your application requires pours over 3 inches, it’s best to consult a sales representative for guidance.
Can it be used in high-temperature environments?
Yes. LC Epoxy Grout performs well in environments with continuous service temperatures up to 180°F (82°C).
How long is the working time?
At 70°F, you’ll have about 30 minutes of working time, which allows for proper placement without rushing.
Is special equipment required for mixing Five Star LC Epoxy Grout?
While specialized equipment isn’t mandatory, using a slow-speed drill or mortar mixer is strongly recommended. Be sure to follow the mixing sequence carefully to ensure full performance.
Can it be used outdoors?
Yes, it’s suitable for outdoor use. Just make sure to protect it from direct sunlight during initial set and confirm that ambient and surface temperatures meet the placement requirements.
What is the shelf life?
When stored in dry conditions and left unopened, LC Epoxy Grout has a shelf life of two years.
