DAP: ALEX PLUS All Purpose Acrylic Latex Caulk Plus Silicone, White, 10.1 oz

I've been using DAP Alex Caulk for several projects around the house, and it consistently delivers excellent results. This caulk is easy to apply, with a smooth consistency that fills gaps neatly without too much mess. It adheres well to a variety of surfaces like wood, drywall, and metal, and once dried, it remains flexible and durable, preventing cracks or shrinkage over time. One of the best features is its paintability — it takes paint nicely, which helps achieve a clean, professional finish. Plus, it dries relatively quickly, speeding up project completion. Overall, DAP Alex Caulk is a reliable and affordable choice for sealing gaps and cracks indoors. Highly recommend it for DIYers and professionals alike!

I purchased this product to seal a leaky rain gutter as it is described as waterproof, adheres to a wide range of surfaces and may be used for both interior and exterior applications. It also states it may be painted after 30 mins, so I assumed I would need to allow at least 12 hours for a full cure. I applied the caulking to a dry gutter Sunday morning, 24 hours before the next rain was forecast. The rain arrived on schedule today (Monday) afternoon – at least 24 hours after application and the gutter leaked. I inspected the caulking at it has dissolved. I would not recommend this product.
