Seal the gap. Get back to your day.

A dripping joint or exposed seam can make a small maintenance job feel bigger than it needs to be. This waterproof butyl repair tape combines a silver aluminium foil backing with a tacky, flexible adhesive to help seal suitable gaps and joints against water, air and dust.

Cut the length you need, peel away the backing and press into place. A practical roll to keep in your home, garage or caravan repair kit.

Silver waterproof repair tape with examples of sealing applications

Built to grip. Flexible enough to fit.

  • Waterproof barrier: helps keep moisture out of properly covered gaps and seams.
  • Pressure-sensitive adhesive: tacky butyl rubber grips a compatible, prepared surface when firmly pressed down.
  • Flexible coverage: the soft adhesive follows joints and contours.
  • Cut-to-size roll: tailor each piece to the repair rather than working with a fixed-size patch.

Useful around the home and beyond

Suitable applications include compatible roof seams, caravan panels, window edges, duct joints and metal or glass joints. Choose a piece wide enough to cover the gap and adhere securely to the surface on both sides.

Examples of sealing tape used on roof seams, window edges and household joints

Simple preparation. A neater finish.

  1. Prepare: clean and dry the surface. Remove dust, grease and loose material.
  2. Measure and cut: allow enough tape to cover the gap and grip on either side.
  3. Peel and position: remove the backing and place the tape carefully.
  4. Press firmly: smooth across the full area and press down the edges.
  5. Leave undisturbed: do not peel off or reposition the tape within 24 hours of application.

Application tips: Wear gloves to handle the sticky adhesive. In cold conditions, gently warm the tape with a hairdryer before fitting. Test a small area first to check surface compatibility. Avoid combining it with silicone or solvent-based waterproofing products.

Before you start

Adhesion and sealing results depend on the surface, preparation and application. The examples shown illustrate possible uses, not a guarantee of suitability for every repair. For significant roof damage or a recurring leak, have the underlying problem assessed rather than relying on tape alone.
