Designed for professional roofers and DIY enthusiasts, the Bond It Seal It Bleed Blocker Primer is an essential one-part solvent-free solution for preparing bitumen, asphalt, and roofing felt surfaces. Its primary benefit is ensuring maximum adhesion of weatherproofing compounds like Seal It Liquid Membrane or EasiSeal Pro, preventing discoloration and bond failure. While highly effective, users must note that the surface must be completely dry and free of debris before application to guarantee optimal performance.

No. The surface must be completely dry to ensure the primer functions correctly and adheres to the substrate.
This primer is formulated specifically for bitumen, asphalt, and felt surfaces; it is not recommended for EPDM rubber.
You do not need to sand, but you must ensure the surface is free of loose materials, dust, and organic growth.
Wait until the primer is touch-dry. Consult the technical data sheet for your specific membrane for exact overcoating times.
As it is solvent-free, it has lower odor, but it is primarily intended for exterior roofing applications. Always ensure good ventilation if used in confined spaces.
Use Bond It Mould Stop to treat any algae or moss before cleaning the surface and applying the primer.
Ensure the surface is completely dry and free of all oil, grease, and dust; any moisture or surface contamination will prevent a proper bond.
This occurs if the primer was applied too thinly or over an area that had residual surface moisture; ensure complete coverage with a uniform layer.
Clean tools immediately after use with warm soapy water. If the primer has already cured, it may require professional-grade cleaners or light mechanical abrasion.
Before starting, ensure your working area is clear of dust, grease, and loose debris. Use a stiff brush or a damp cloth to clean the surface, but allow it to reach a bone-dry state before opening the primer. The product is designed specifically to work with Seal It Liquid Membrane and EasiSeal Pro. Store the container in a cool, frost-free environment. After application, clean brushes and tools immediately with warm soapy water while the primer is still wet, as hardened primer may require solvent cleaning or mechanical removal.
