IKO Permascreed H

IKO Permascreed H (Heavy Duty) is a robust and effective screeding solution for flat roofs, walkways, and heavily trafficked vehicle decks. It is ideal for both new build and refurbishment projects.

IKO Permascreed H (Heavy Duty) can be installed in multiple layers to create precise drainage falls, level uneven substrates, and provide a stable, durable base for specified roof waterproofing and deck surfacing systems.

Our mastic asphalt screed offers a rapid, reliable alternative to traditional sand and cement screeds. Manufactured from selected bitumen, limestone filler, and specially graded aggregates, it delivers long-lasting performance in demanding environments.

Designed for use on all flat roofs, walkways, balconies, car parks, and HGV service decks, it should always be applied in accordance with IKO recommendations.
