Stop Leak Sealer Spray is designed to seal and waterproof leaks in gutters, flat roofs, pipes, and other surfaces. It creates a flexible, weather-resistant barrier that helps prevent further water damage.

This spray works on metal, concrete, wood, plastic, asphalt, and most roofing materials. It is ideal for gutters, roofs, flashing, vents, pipes, skylights, and other exterior surfaces.

4. Is this sealer waterproof?

Yes, once fully cured, it creates a waterproof and weatherproof barrier to protect against rain, snow, and moisture.

5. How long does it take to dry?

It typically dries to the touch within 30 minutes, but full curing may take 24–48 hours depending on temperature and humidity.

6. Can I paint over the sealed area?

Yes! Once fully dried and cured, most types of paint can be applied over the sealed surface.

7. How long does the seal last?

The seal is durable and long-lasting, but exposure to extreme weather conditions may require periodic reapplication for best results.

9. How do I apply this spray properly?
