Product Information
Full details
Bitubond Bitumen Primer is an essential solution for professional contractors and DIY enthusiasts preparing surfaces for bitumen-based coatings, tapes, or mastics. It provides deep penetration to seal porous materials and improve adhesion for roofing and flooring projects, though it requires a completely dry surface for effective application, making it less suitable for damp or rainy conditions.

FAQs
Can I use this on wet roofs?
No, the surface must be completely dry and clean before application for the primer to bond correctly.
Is this compatible with non-Bond It products?
While it is part of the BITUBOND system, it is a general-purpose bitumen primer that can be used under most standard bituminous coatings, though testing on a small area is recommended.
How do I clean my brushes after use?
As this is a bitumen-based product, you will likely need a solvent-based cleaner such as white spirit to clean tools.
Does this work on rusted metal?
Yes, it is suitable for weathered corrugated iron, provided loose rust has been removed by brushing before application.
Can this be used on internal floors?
This product is typically intended for external or industrial use. Ensure there is significant ventilation if using in any enclosed space.
Troubleshooting
Primer is not drying correctly
Check if the substrate was damp. Bitumen primer will not cure properly on moisture-laden surfaces. Ensure the area is completely dry.
Poor adhesion of topcoat
Ensure the primer was applied uniformly and allowed to become 'touch-dry' before applying the next layer.
Pros and Cons
Pros
- High-penetration formula ensures excellent adhesion
- Versatile use on both porous and metallic surfaces
- Essential for preparing substrates before bitumen roof coatings
- Easy to apply with standard brushes or rollers
Cons
- Requires completely dry surfaces for proper curing
- Contains bitumen, requiring careful handling to avoid staining
- Not intended for use on damp or wet substrates
Setup, Compatibility & Care
Before application, ensure the surface is structurally sound, clean, and entirely dry. Remove all loose debris, grease, rust, and oil using a wire brush or cleaning agent if necessary. Once clean, apply the primer using a stiff-bristled brush or roller.
Compatibility:
- Suitable for: Concrete, cementitious screeds, renders, bitumen felt, mastic asphalt, weathered corrugated iron, and steel.
- Not suitable for: Surfaces that are wet, damp, or contaminated with loose contaminants.
Care: Store the container in a cool, dry place with the lid tightly secured to prevent solvent evaporation. Always use in a well-ventilated area due to the nature of the solvent-based formulation.
