Demidekk Cleantech is based on advanced Alkyd Modified Acrylic (AMA) technology developed in Norway and manufactured by AVACE in the UK, providing up to 12 years’ protection against moisture, UV degradation and harsh weather when applied correctly.
Demidekk Cleantech is recommended for luxury log cabins, garden rooms, cladding, decking, fencing and exterior furniture, giving you one high‑performance system that can protect almost all exterior timber around your home and garden. It replaced Demidekk Ultimate, with enhanced durability and easy clean properties.
Demidekk Cleantech and Demidekk Ultimate are fully compatible AMA‑based systems, so Cleantech can be applied over sound Demidekk Ultimate; it can also be used over existing stained or painted wood that has been properly cleaned and prepared.
For new, bare or exposed exterior timber Avace recommends Jotun VISIR clear which penetrates the surface, providing additional water repellency and creates the ideal base for Demidekk Cleantech.
