What Customers Are Saying

Customers overwhelmingly praise this latex caulk for its ease of application, reliable performance, and excellent value. Most highlight how smoothly it applies and cleans up with just water, making it ideal for DIY projects. Reviewers consistently report strong, long-lasting seals suitable for windows, trim, siding, and exterior applications like decks and gutters. Many appreciate that it dries clear after application, remains flexible without cracking, and is paintable for a professional finish. A few note confusion about the white color in a clear-labeled tube, and a small number report it runs too thin. Overall, customers express strong loyalty and recommend it as a top choice for both interior and exterior caulking needs.
