Mile High Foam is a closed cell polyethylene backer rod serving as a backing for elastomeric and other applied caulking sealants. Mile High Foam controls the depth and amount of sealant required.
Mile High Foam also forms the correct hour glass shape of sealant, assuring the contractor and owner the best adhesion and cohesion configuration possible.
For use in expansion/construction joints in concrete and precast concrete walls, floors, partitions, bridge construction, parking decks, curtain walls, glazing, log home construction, highway construction, and pavement maintenance. Mile High Foam is compatible with most cold applied sealants.
Whatever restriction the Sealant Manufacturer places on his product the same will apply to Mile High Foam.
