Waterproof Tapes

When water is the enemy, the right tape is the first line of defence. At the DIY Hardware Store, our waterproof tapes range covers the gaffa tape, flashband self-adhesive flashing, double-sided bonding tape, and wall repair scrim used for weatherproofing, emergency repairs, and permanent waterproofing joints in building and DIY applications.

Flashband is the definitive product in this range - a self-adhesive bitumen-backed aluminium or polymer-faced flashing tape used to seal around roof penetrations, patch damaged flashings, waterproof box gutter joints, and create emergency weatherproof repairs on damaged roof coverings. It bonds to most dry surfaces at temperatures above 5 degreesC and provides an immediate, durable weatherproof seal without heat or specialist tools. Gaffa tape in its heavy-duty format provides strong, weather-resistant bonding for temporary outdoor repairs. Wall repair scrim reinforces repaired crack lines before over-plastering.
