Forget waiting for sunshine that never turns up. BANDIT™ is a single-component liquid roofing membrane built for real British weather — it’ll go down on wet or dry substrates, grab on tight, and cure into a seamless, flexible, UV-stable skin over your flat roof.

You don’t need burners, primers, or a science degree. Open the kit, give it a mix, roll it out, job done.

What It Is

BANDIT™ is a high-performance MS polymer liquid membrane designed for:

• New flat roofs

• Overlaying sound existing membranes

• Patch repairs around details, seams, gutters, and awkward penetrations

It self-levels, sticks like hell to most common roofing substrates, and shrugs off standing water once cured.

What’s in the Kit

• 1 × 1kg pouch of roof repair liquid membrane
• 1 × mixing tub
• 1 × application brush
• 1 × bandage sheet (reinforcement)
• 1 × pair of gloves

Why Tradies Rate It

• Works on damp surfaces – ideal for “typical UK summer” conditions

• One-part system – no mixing ratios to mess up, just stir and go

• Fast skin time – tacks off in around 40 mins at 20°C so you’re not babysitting it all day

• High elasticity – around 250% elongation, moves with the roof instead of cracking

• UV stable – built to take sunlight without turning to chalk

• Odourless & solvent-free – nicer to use on live sites, schools, homes, and occupied buildings

• Isocyanate-free – no nasty surprises in the small print

• Resistant to standing water – built for flat roofs, not just “low slope-ish” marketing chat

• Tested service life – W2 classification, minimum 10-year life expectancy when applied as per data sheet

Where You’d Use It

Perfect for:

• Leaking felt or single-ply flat roofs (where the substrate is still sound)

• Garages, extensions, dormers, bay windows, porches

• Problem details – laps, outlets, rooflights, upstands, edge trims

• Emergency repairs when the forecast’s grim but the phone’s ringing

If you’ve got to repair a leak, then BANDIT™
