Product Information
Full details
Bond It Bitumen Primer is a professional-grade, high-penetration solvent-borne primer designed for contractors and homeowners looking to seal and stabilize porous or dusty surfaces prior to applying waterproofing systems. Its primary benefit is the significant enhancement of adhesion for bitumen coatings, mastics, and flashing tapes across a diverse range of substrates. While it offers excellent durability and fast drying times, users should note that as a solvent-borne product, it must be used in well-ventilated outdoor areas to avoid fume inhalation.

FAQs
Can I use this on wet surfaces?
The surface should be as dry as possible. While it is rain-resistant once applied, applying it to standing water or saturated surfaces will prevent proper penetration.
Is this product suitable for indoor use?
No, this is a solvent-borne product that releases fumes. It should only be used in outdoor, well-ventilated areas.
Do I need to mix this primer with anything?
No, it is a ready-to-use product. Stir it well within the tin before use, but do not dilute it.
How do I clean my brushes after use?
Use white spirit or a professional solvent cleaner immediately after finishing your application.
What is the coverage rate?
Coverage depends on the porosity of the surface, but a 5L tin is designed for high-efficiency coverage on standard commercial and domestic substrates.
Troubleshooting
The primer remains tacky for an extended period.
Check if the application layer is too thick. Ensure the surface was dry and ambient temperatures are not too low.
Poor adhesion of the topcoat.
Ensure the primer was fully dry before applying the waterproofing system. Ensure the surface was free of loose dirt before the primer was applied.
Primer is too thick to spread easily.
Store the tin in a warmer environment for a few hours before use; do not add thinners or water.
Pros and Cons
Pros
- Excellent surface stabilization for dusty or porous substrates
- High versatility across metal and mineral-based surfaces
- Fast drying time reduces project wait times
- Easy cold-applied consistency
Cons
- Strong solvent odor requires outdoor or well-ventilated use
- Not suitable for indoor residential spaces without professional ventilation
- Standard black finish may show through thin topcoats
Setup, Compatibility & Care
Before use, ensure the surface is free of oil, grease, and loose debris. Stir the contents of the 5L tin thoroughly before application. No thinning is required. Apply in a single, consistent coat; avoid pooling the product, as thick layers may take significantly longer to cure.
Compatibility: Use on concrete, cement, metal (iron/zinc/lead), bitumen felts, and slate. Not recommended for use over non-bituminous plastics or surfaces treated with non-compatible sealants.
Care: Store the tin in a cool, dry place with the lid tightly sealed to prevent solvent evaporation. Clean brushes and tools using white spirit or a standard solvent cleaner immediately after use to prevent the bitumen from hardening on the bristles.
