Leaks that start as a trickle and become a problem. Cracks that let water in over winter. Seams that fail after years of UV and movement. AquaShield Pro bonds to any surface and stops water where it enters — permanently.
- ✔Bonds to wet surfaces — applies and bonds even to damp or wet substrates; no need to wait for dry weather to seal a leak
- ✔Universal adhesion — bonds permanently to concrete, brick, metal, tile, wood, glass, rubber and most plastics without primer
- ✔Flexible when cured — remains elastic after drying so it moves with thermal expansion and contraction without cracking or losing its seal
- ✔UV and temperature resistant — maintains bond and waterproofing from -20°C to +120°C and resists UV degradation for long-term outdoor use
- ✔No shrinkage on curing — sealant volume is maintained through curing; no gaps or air pockets that would create future failure points
- ✔Easy gun application — standard cartridge fits all caulking guns; smooth, controlled bead application with no specialist tools needed
- ✔Paintable surface — can be overpainted once cured for a seamless, invisible repair on interior and exterior surfaces
💧 30-Day Money Back Guarantee — If it doesn’t seal the leak or bond to the surface, return it for a full refund.
Yes. This is one of the key features that separates AquaShield Pro from standard sealants. It bonds to wet and damp surfaces and will continue to cure even in rainy conditions. Clean the surface of dirt and loose debris before applying but you do not need to wait for it to dry.
Concrete, brick, stone, render, metal (including aluminium and galvanised steel), ceramic tile, glass, timber, fibreglass, rubber, UPVC and most rigid plastics. It does not bond to polyethylene or polypropylene.
No. The formula remains permanently elastic after curing, allowing it to flex with thermal movement without losing its seal. This is essential for outdoor applications where temperature changes cause surface expansion and contraction.
Skin-over time is typically 30–60 minutes depending on temperature and humidity. Full cure to maximum strength takes 24–48 hours. Light rain resistance is achieved within a few hours of application.
Yes. Once fully cured, the surface can be overpainted with most water or solvent-based paints for an invisible repair. Allow full cure before painting and test on a small section first if using a specialist coating.
What Our Customers Say
Applied this to a leaking flat roof seam in light drizzle. It bonded perfectly despite the wet surface. Two months and three significant rainfall events later — completely dry inside. Extraordinary product.
Used on cracked concrete around my pool surround. The flexibility on cure is genuine — it’s been through a full summer of expansion and contraction without any sign of cracking. Standard sealants fail this test within months.
Sealed a joint between my garage roof and wall that had been letting water in for two winters. Applied it with a standard gun, smoothed it off, painted over it a week later. Not a drop of water since. Permanent fix.
Used to seal around all the window frames on my shed. Strong adhesion to both wood and metal without primer. Eleven months later everything is still fully sealed through a wet winter. Excellent quality product.
Professional builder. Used this on a tricky flashing repair in the middle of a wet spell — had no choice but to seal in the rain. Bonded beautifully, cured properly, held perfectly. Now my go-to sealant for wet conditions.
