More Star-Seal Supreme® Information

Application:
Star-Seal® Supreme must be applied on structurally sound pavement by professional applicators.

Coverage rates:
0.18 to 0.20 gal/sq. yard of the concentrated Star-Seal® Supreme, in two coat application. Coverage rates may vary depending upon the porosity and texture of the pavement surface.

Dilution:
Maximum 20% by volume on the volume of the concentrated Star-Seal® Supreme, with clean potable water.

Aggregates Addition:
Clean silica sand or synthetic aggregates with an average grain fineness between 50 - 70 shall be added for increased traction and textured appearance. Not recommended for steeply inclined surfaces.

Method:
Mechanical or spray applicators, brush or squeegee.

TECHNICAL RESEARCH
The two most important factors in sealcoating strength and longevity are resistance to water absorption and traffic abrasion.
The following demonstrate why Star-Seal® Supreme performs so well in "real world" situations.

WATER ABSORPTION PROFILE
The cured films of sealcoatings have varying degrees of water absorption, depending upon the water sensitivity of the ingredients used in their formulations.

Star-Seal® Supreme is formulated the least water sensitive ingredients and is therefore least affected by the problems associated with water absorption.

SCRUB RESISTANCE UNDER WATER
(ASTM D-2468 modified)
The cured films of sealcoatings frequently encounter rain, snow and sleet. It is extremely important that these films retain their performance properties under such conditions and not be prematurely eroded by traffic.

The scrub resistance test has consistently proven Star-Seal® Supreme to have excellent durability under water.

Star-Seal® Supreme exceeds the requirements of FEDERAL SPECIFICATION RP-355e, when tested in accordance with the following: ASTM STANDARDS.
