Premium Additives & Primers Engineered for Performance & Efficiency

MAC Pavement Maintenance Products offers premium-grade additives and primers designed to improve the durability, flexibility, appearance, and drying time of your sealcoating projects.

Sealer Additives

STAR MACRO-FLEX

MACRO-FLEX® is a rubberizing latex additive that strengthens specialty resin, refined tar, and asphalt emulsion sealcoatings by enhancing toughness, flexibility, sand suspension, and resistance to petrochemicals and de-icing salts.

STAR MAX-DRI

MAX-DRI® is a triple-action acrylic additive that speeds drying, boosts performance, and enhances viscosity for both asphalt emulsion and refined tar sealcoatings.

STAR ADVANTAGE 4

ADVANTAGE 4 is a high-potency, acrylic-based additive that accelerates drying, boosts performance, enhances color, and increases viscosity for both refined tar and asphalt emulsion sealcoatings.

STAR MACRO-FAST

MACRO-FAST is a latex-based additive that accelerates dry times by up to 50% without altering viscosity, making it ideal for cooler or high-humidity conditions and time-sensitive sealcoating projects.

STAR LTCA (Low Temperature Cure Additive)

LTCA improves the curing process in lower temperature conditions, extending the working season for sealcoating projects. Ideal for early spring, late fall, or colder climate applications.

Primers

SS-1H

A slow-setting asphalt emulsion used primarily as a tack coat to promote strong adhesion between pavement layers. It can be applied at full strength or diluted to adjust viscosity, offering reliable performance across a variety of paving conditions. Available in 5-gallon buckets and bulk.

STAR S.O.S. SEALER

A latex-based primer designed to seal oil and grease spots on asphalt pavement before sealcoating. STAR S.O.S. SEALER forms a tough, durable layer that prevents bleed-through and allows asphalt emulsion and refined tar sealers to adhere properly to contaminated areas—minimizing prep work and improving finish results

STAR GENESIS PRIME

GENESIS PRIME is an evolutionary product which was designed to double as an all-purpose primer and sealer for both asphalt and concrete surfaces. Dries to an attractive black finished surface. It effectively bonds and seals all problematic areas, oil spots, grease contaminations, polished aggregates, and fresh asphalt patches.
