Bartoline Leak Sealer is a professional-grade waterproof spray sealant designed for homeowners and contractors who need to instantly bridge cracks and stop leaks on various exterior and interior surfaces. Its primary benefit is the ability to form a durable, weather-resistant, and overpaintable barrier on difficult substrates like UPVC, metal, and concrete. However, users should note that the product requires specific temperature conditions (15C to 25C) and excellent ventilation during application to ensure proper curing and safety.

No, this product is not certified for contact with potable water systems.
Drying times vary based on thickness and ambient temperature, but you should allow for several hours before testing for water tightness.
It is designed for sealing leaks in gutters, roofs, and non-pressurized drainage; it is not recommended for high-pressure plumbing.
No, the surface must be clean and dry at the time of application for the sealant to bond correctly.
The sealant is black, but it is formulated to be overpaintable if you wish to change the color.
Remove the nozzle and soak it in a solvent compatible with aerosol cleaners, or replace it if damage is permanent.
Ensure the application temperature was within the 15C to 25C range and check that the surface was completely clean and dry before spraying.
Apply thinner coats and increase the distance from the surface to the nozzle.
Before using Bartoline Leak Sealer, ensure the area is free of dust, grease, and loose debris. Shake the can vigorously for at least one minute before use to ensure the chemical components are properly mixed. Hold the can 15-25cm away from the surface and apply in light, even coats rather than one heavy layer to prevent dripping. Always operate the spray in a well-ventilated area, preferably outdoors, to avoid inhaling fumes. Store the can in a cool, dry place away from direct sunlight and temperatures exceeding 25C. Keep the nozzle clear by holding the can upside down and spraying for a second after use to clear the valve.
