Bitumen Primer

Newton HydroBond 2K-Flex Primer is a black, bitumen primer liquid. It is designed for the external waterproofing of retained structures when used in conjunction with Newton HydroBond 2K-Flex. It is highly effective at lowering porosity of concrete and masonry substrates.

This bitumen primer adheres well to concrete, masonry, plaster and other common construction substrates. It can also be used as a primer for horizontal surfaces prior to cold-applied, seamless rubber waterproofing membranes.

Simply stir briefly then brush or roller the bitumen primer onto the prepared substrate. Once it has fully dried, you can apply the Newton HydroBond 2K-Flex bitumen waterproof coating as per manufacturer’s instructions.
