Liquid & Top Coat

Ultraflex is a high-performance liquid waterproofing system that can be applied straight from the tin onto a new or existing flat roof to form a seamless membrane.

Designed to be used in conjunction with Ultraflex Matting and Topcoat, the Ultraflex system is highly suitable for waterproofing extensions, balconies and terraces, including detailed areas, such as box gutters.

Ultraflex has been consciously manufactured to be usable for both industry professional and DIYer alike, on substrates ranging from torch-on felt and plywood, to metal and concrete.

Simply apply Ultraflex onto the substrate using a solvent resistant roller, dry roll Ultraflex matting into the Ultraflex until it is drawn through, then immediately apply another coat of Ultraflex to a minimum thickness of 1.5mm to fully embed the matting, while avoiding any pinholes.

Practical for both new projects and repair jobs, Ultraflex can be applied all year round in most temperatures to provide a waterproof surface area of 10 sqm up to 1,000 sqm.

Ultraflex is fully trafficable within 24 hours of application and BBA certified for a lifespan in access of 25 years. A full list of technical data can be found in the PDF on the right-hand side of this page.
