Newton HydroBond 2K-Flex Primer is a quick-drying, solvent-free bitumen emulsion primer designed for preparing concrete and masonry substrates. It is specifically formulated to be used in conjunction with the Newton HydroBond 2K-Flex bitumen waterproofing coating. By penetrating the surface, it significantly reduces the porosity of the substrate, ensuring a superior bond for the subsequent waterproofing layers. It is suitable for application on various common construction materials, including concrete, brickwork, and plaster, providing an essential foundation for external "Type A" barrier waterproofing systems. Benefits Deeply penetrates concrete and masonry to reduce surface porosity Dramatically improves the adhesion and bond strength of HydroBond 2K-Flex coatings Solvent-free and non-toxic, making it safer to use in confined or sensitive areas Quick-drying formula allows for faster project progression Easy to apply by brush or roller directly from the container Good to know Supplied in 10-litre containers Coverage is approximately 200 ml/m² (approx. 50m² per 10L unit), depending on substrate porosity Important: Not suitable for use on ICF (Insulated Concrete Form) structures Substrates should be clean, dry, and free from dust or loose material before application
