Product Information

Full details

The Evo-Stik Flashband is designed for homeowners and professional tradespeople looking for a reliable, immediate solution to roofing leaks and weatherproofing gaps. Its primary benefit is the ability to provide an instant, durable, and watertight seal on a variety of building surfaces without the need for complex tools or heat. Users should note that while it is highly effective, it requires a clean, dry surface for optimal adhesion and is not suitable for surfaces exposed to extreme, sustained high temperatures.

FAQs

Can I use Flashband on wet surfaces?

No, the surface must be completely dry for the adhesive to bond correctly.

Is this product suitable for high-heat environments?

Flashband is not designed for surfaces that reach high, sustained temperatures and may lose its integrity.

What tools do I need for installation?

You only need a pair of strong scissors to cut the tape to size and a roller to ensure full contact.

Can I paint over the Flashband?

It is generally not recommended to paint over the surface, as the material is designed to be weather-resistant in its natural state.

How do I remove the release film?

Simply peel back the protective film gradually as you apply the tape to the surface to prevent it from sticking to itself.

Troubleshooting

The tape is not sticking firmly to the surface.

Ensure the surface is completely dry and clean. Remove any moss, loose grit, or oily residue before re-applying.

Air bubbles are trapped beneath the tape.

Use a wallpaper seam roller or a clean cloth to apply firm pressure from the center of the tape outward to the edges.

The tape is peeling at the edges.

Clean the area thoroughly, let it dry, and apply a small overlapping patch if necessary to reinforce the bond.

Pros and Cons

Pros

  • No specialized tools or heat required for application
  • Excellent adhesion to multiple building materials
  • Ideal for emergency leak repairs
  • Weather-resistant and durable construction
  • Easy to cut and fit into tight or complex spaces

Cons

  • Requires a clean and dry surface for proper bonding
  • Not suitable for high-temperature applications
  • Single-use product once the adhesive backing is applied
  • May require extra care on porous surfaces

Setup, Compatibility & Care

Before application, ensure the substrate is clean, dry, and free from loose debris, dust, or grease. If the surface is porous, such as bare brick or concrete, applying a primer may improve the initial tack. To apply, peel back the release film as you press the tape into position, working from one side to the other to avoid creasing. The product is compatible with most standard building materials, including bitumen, metal, and plastic. For ongoing care, periodically inspect the seal for any signs of lifting or damage, particularly after extreme weather events, and re-apply a fresh layer if necessary.
