The solution also needed to be odourless, as important air intakes were adjacent to the roofs being refurbished. The Trust decided to overlay the existing roofs with a new liquid waterproofing membrane which offered a fast cure time, low odour application and minimal disruption.
To meet the requirements, the licensed contractor specified the Cold Melt® seamless waterproofing system from Proteus Waterproofing to extend the lifespan of the roof. Chosen for its extremely low odour installation, Cold Melt® was selected with a Cold Melt® UV top coat finish to ensure UV stability. The additional benefit of this system was the slip-resistant aggregate finish which improved the safety of all refurbished areas where foot traffic is experienced.
