Five Star Epoxy Novolac Grout is a precision-engineered, three-component epoxy grout designed to withstand the harshest chemical environments encountered in industrial applications. Built with a 100% solids formulation and a novolac resin system, it provides long-term resistance against aggressive substances like concentrated acids, alkalis, solvents, and corrosives. This makes it especially suited for environments where chemical exposure is constant and extreme — such as chemical processing plants, refineries, pulp and paper mills, and wastewater treatment facilities.
The grout’s expansive, nonshrink behavior helps maintain consistent load transfer and dimensional stability, even under dynamic or thermal stress. Its high flowability simplifies placement under machinery baseplates, tank pads, and structural supports, particularly in tight clearances. Achieving a 95% Effective Bearing Area (EBA), Five Star Epoxy Novolac Grout ensures solid contact and dependable load distribution. Whether used for grouting equipment foundations or in critical containment areas, it delivers a combination of strength, durability, and chemical resistance that meets the demands of today’s industrial standards.

Frequently Asked Questions
What makes Epoxy Novolac different from standard epoxy grouts?
It incorporates a novolac resin system for superior resistance to concentrated acids and bases, especially in immersion service or high-temperature settings.
Can Five Star Epoxy Novolac be used for deep pours or large volume placements?
For large pours or when clearance is outside the standard range (less than ½” or more than 6″), contact a sales representative to evaluate placement strategy.
What temperature range can Epoxy Novolac handle during installation?
The ideal range is 65°F to 85°F. For installation outside 55°F to 90°F, or continuous service above 200°F, follow Design-A-Spec guidelines or consult a sales representative.
Is Five Star Epoxy Novolac suitable for vertical or overhead placement?
No, this product is designed for horizontal pours under baseplates or in containment structures with formwork support.
How Five Star Epoxy Novolac mixed and applied?
Resin and hardener are mixed first, then the aggregate is gradually blended in using a mortar mixer. The grout is then poured from one side to maintain contact under the baseplate.
