Product Information

Full details

Its primary benefit is a high-performance, fibre-reinforced formula that delivers a durable, waterproof seal capable of bridging cracks on various surfaces; however, users should note that as a solvent-based product, it requires adequate ventilation and careful handling during application.

FAQs

Can I use Black Jack 905 on flat roofs?

Yes, it is designed for use on flat roofs, gutters, and various other roof surfaces requiring a waterproof coating.

Is this product suitable for use in the rain?

While it is an all-weather coating, it should ideally be applied to a dry surface for the best bond, though it resists wash-off quickly after application.

What tools should I use for application?

You can use a stiff-bristled brush or a dedicated roof broom for wider coverage.

How do I clean my brushes after use?

Clean brushes thoroughly with white spirit or a professional-grade solvent cleaner immediately after use.

Does it need a primer?

On most standard roof surfaces, a primer is not required, provided the surface is clean and debris-free.

Can I paint over the black finish?

This product is designed as a final protective coating; it is not recommended to paint over it.

Troubleshooting

Product is too thick to spread easily

Store the container in a warmer area for a short period before use or mix thoroughly to loosen the consistency.

Poor adhesion to the surface

Ensure the surface is completely free of dust, grease, and moisture before re-applying; the product will not bond effectively to damp surfaces.

Surface remains tacky after long periods

This typically indicates the layer is too thick or ambient temperatures are too low; allow more time for the solvent to evaporate.

Pros and Cons

Pros

  • Excellent crack bridging capabilities due to fibre reinforcement
  • Fast-drying formula reduces downtime between coats
  • Provides a long-lasting, weatherproof seal
  • High adhesion properties on various substrates

Cons

  • Strong solvent odor requires well-ventilated work areas
  • Black color limits its aesthetic use to specific roof types
  • Requires professional-grade cleaning of tools after use

Setup, Compatibility & Care

Before application, ensure the roof surface is clean, dry, and free from loose debris, moss, or standing water. Remove any grease or oil stains to ensure optimal adhesion. The product can be applied using a brush or a roof broom for larger surface areas. After application, clean tools immediately using a suitable solvent like white spirit, as the product hardens significantly once fully cured. Store the container in a cool, dry place, ensuring the lid is airtight to prevent the solvent from evaporating.
