Surface protection
With the exception of vertical and steeply sloping work, the finished IKO Permaphalt LI must be sand rubbed to reduce the incidence of crazing. A protective surface should be applied to all flat areas using a suitable solar reflective paint, stone chippings or promenade surfacing.
