Application:
ES500 should be rolled out, with the peduncles on the underside (reverse rolling may be required at low temperatures), and cut into the perimeter. The underlayment should lay flat with no distorting bumps. Joints should be abutted and taped using TREMCO approved water proof jointing tape. All air must be excluded. ES500 should be laid in the same direction as the finishing flooring, but the positions of the joints should not correspond.

Most floor coverings can be adhered to ES500 with the appropriate TREMCO adhesive. Always refer to the Tremco CPG UK Limited Technical Department for correct adhesive selection.
