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. 

HydroBond 2K-Flex Primer 
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.

HydroBond 2K-Flex Mesh
A reinforcing mesh made from woven fibreglass yarns and coated with alkaline resistant latex which prevents the alkaline present in cement from degrading the glass fibre.

Key Benefits:

• Fast reaction time due to the special powder catalyst.
• Highly flexible with 2mm crack bridging due to high-quality polystyrene and polymer modification.
• Quick-drying and rain-fast after a short period.
• Solvent-free, non-toxic and odourless.
• Non-flammable - No VOCs.
• Radon gas resistance.
• Sprayable with suitable equipment.
• Adheres insulating panels to concrete, masonry and thoroughly dried thick bituminous coatings.
