Product Description
Raven 581 is a 100% solids, no VOC, modified polyurethane designed for use as a maintenance hole/ manhole “chimney seal.”
It can be applied in high humidity conditions with minimal bubbling and loss of adhesion. It adheres well to properly prepared concrete, steel, aluminium, wood, composites, and many other substrates.
Some substrates exhibit much better long term performance if a primer is used prior to application. If you’re interested in primer recommendations please get in touch.
