Polyester multi layer overlays provide a 3/8” thick, two layer overlay system with superior bond, high friction values and a two hour traffic return in a variety of conditions.

Features

Ultra low permeability

Seals bridge deck surface from chloride and moisture instrusion

Restores friction

Angular aggregates restore friction to the riding surface.

Superior adhesion

Superior performance and bond strength through penetrating healer/sealer primer

Rapid return to service

Rapid 2 hour cure time after placement, even in conditions down to 40ºF
