Description
Primer for HydroBond 2K-Flex
A fast-drying bitumen emulsion primer and bonding agent that is applied to the substrate prior to the application of the Newton HydroBond 2K-Flex reinforced bitumen waterproof coating. The product adheres well to concrete, masonry, plaster and most other common construction substrates.
For use with:-
HydroBond 2K-Flex
A radon gas certified, bitumen/rubber waterproofing membrane used primarily for the external waterproofing of earth-retaining structures such as basements and foundation walls. Forms a thick, highly flexible barrier to water ingress that can be applied to fill voids, cracks and joints.
Environmentally friendly and solvent-free, HydroBond 2K-Flex consists of two components; a bitumen emulsion and a reactive powder. These two components chemically react when mixed to produce a firm, yet still highly flexible coating that can be applied by trowel or by airless spray machine. Adhering insulated panels to concrete, masonry and thoroughly dried thick bituminous coatings, 2K-Flex dries quickly and is rain-fast after a short period.
HydroBond 2K-Flex requires two ancillary products, HydroBond 2K-Flex Primer and HydroBond 2K-Flex Mesh.
