Newton Hydrobond 2K-Flex Primer

Primer for HydroBond 2K-Flex – Fast-Drying Bitumen Emulsion

HydroBond 2K-Flex Primer is a fast-drying bitumen emulsion primer and bonding agent, designed for use with Newton HydroBond 2K-Flex reinforced bitumen waterproof coating. It ensures strong adhesion to a variety of construction substrates, including concrete, masonry, plaster, and more, providing a reliable base for waterproofing applications.

For Use With:

🔹 HydroBond 2K-Flex – A radon gas-certified, bitumen/rubber waterproofing membrane used for external waterproofing of earth-retaining structures such as basements and foundation walls. It forms a thick, highly flexible barrier to water ingress, filling voids, cracks, and joints for superior protection.

HydroBond 2K-Flex is an environmentally friendly, solvent-free, and quick-drying waterproofing system that adheres insulated panels to concrete, masonry, and thoroughly dried bituminous coatings. It requires two ancillary products:
✔ HydroBond 2K-Flex Primer – Ensures strong adhesion to substrates
✔ HydroBond 2K-Flex Mesh – Reinforcement for added durability

Key Benefits:

✅ Fully bonded, seamless waterproofing membrane with superior crack-bridging capabilities
✅ Lightweight & easy trowel application – Simple handling with minimal effort
✅ Fast reaction time – Special powder catalyst ensures rapid curing
✅ Highly flexible – Bridges cracks up to 2mm due to polystyrene and polymer modification
✅ Quick-drying & rain-fast – Provides rapid protection after application
✅ Solvent-free, non-toxic & odourless – Safe for all environments
✅ Non-flammable & VOC-free – Environmentally friendly formulation
✅ Radon gas-resistant – Provides additional protection against harmful gases
✅ Compatible with spray application – Suitable for large-scale use
✅ Bonds insulating panels to concrete, masonry, and bituminous coatings

Typical Applications:

✔ Continuous Type A waterproofing & radon protection in conjunction with Newton HydroBond pre-applied membranes
✔ Type A waterproofing & radon membrane for basements, foundations, and earth-retained walls
✔ Smoothing of irregular surfaces before applying bitumen-based membranes
