A Water-based, Asbestos-Free Treatment for Maintaining Built-Up Roof Membranes

ECOLastic is formulated to maintain weathered, dry roof membranes and improve the self-healing characteristics of coal tar pitch.  It effectively restores pliability of built-up roof bitumens.

It is recommended for use as surfacing adhesive for new asphalt and gravel constructions, for new tar and gravel roofs, and for new modified bitumen roof systems.


The asbestos-free ECOLastic is blended with special aromatic oils and additives, formulated to be compatible with both tar and asphalt roof membranes.
