Después de varios días de lluvia, las paredes siguen intactas.muy buena opción para reparaciones en casa. La recomiendo 10 de 10
Review: Not worth a penny... - It took weeks to receive product as if it is in high demand. I'd not know why. I'd have just bought paint. The can was almost half empty and as I said, normal paint would do a much better job. For the price of this item, I'd have bought two gallons of paint. Rip off is what I call this item...

## Features

- Efficient Leak Prevention：Polyurethane waterproof coating protects surfaces and repairs leaks. Use on flat roofs, sloped roofs, external wall cracks, foundations, sheds, basements, metal, wood, concrete, gutters, skylights, windows, RVs, DIY projects, external walls, pipelines, seals pipeline leaks, walls, corners, toilet leaks, substrate joints, car roofs, pools, baths, and more. (Note: Not suitable for continuous soaking or use below the waterline.)
- High Quality: The polyurethane waterproof sealants/coatings are water-based. The roof sealant provides excellent waterproofing, is long-lasting, and resists both low temperatures and heat. Using the leak repair waterproof coatings forms a durable protective film, helping to save time, money, and energy.
- Coverage: Each 1000g/32 oz of polyurethane sealant covers about 14 sq ft (1.3 sq m). Apply in 3-5 thin layers. This waterproof coating easily adheres to surfaces, repairing holes, cracks, crevices, tears, and leaks, while sealing any cracked areas. The roof sealant also creates a protective waterproof layer in the treated area.
- Waterproof Agent Tip:Prolonged rainy and humid conditions, along with cooler temperatures, can extend the curing time for the waterproof adhesive. For best results, select clear, dry weather and maintain a dry environment before and after application. Ideal operating temperature: 10˚C/50˚F or higher (including overnight).
