Rated 3.7 out of 5 by 3reviewers.
Rated 5 out of 5 by The trick is to let it dry thoroughly I have tried scores of caulks over thirty years of home maintenance projects, I have settled on Dynaflex for most interior and exterior uses, with the exception of places I know are either going to stay really wet, or need to be painted quickly. DAP's Sidewinder works well for those caveats, but it's harder to clean up and it doesn't finger tool as well. I'm only writing this review because someone was asking me about caulks today, and I couldn't quite think of "Dynaflex" since I didn't have a tube of it handy---so I checked DAP's website for the name, then came across the review from the person who had trouble with paint adhesion. My guess is that the gaps were wide enough to need a little extra drying time. I wait until the whitish color goes away completely, then it's safe to paint. It's flexible, it's easy to work with, it doesn't reek, it's easy to clean up, and it's relatively inexpensive. September 3, 2016
Rated 1 out of 5 by paint won't adhere We replaced siding trim on a back porch exterior with Hardy board and used this caulk to seal all edges and holes. It dried overnight and the next day we painted with Sherwin Williams Emerald exterior acrylic latex paint (very expensive), and it would not cover the caulked areas. Everywhere we caulked the paint bubbled. After painting the caulked areas 4-5 times, the cover was finally almost acceptable. We will never use this product again and are returning what is left to the store. June 26, 2016
Rated 5 out of 5 by GOOD STUFF! As a General Contractor I have tried many caulking products over the past 25 years and I have to say this is my go to caulk. I not only use it on exterior projects but it also works great caulking in backsplashes and trim components. Have also inspected projects several years after completion and the caulking still looks great. May 16, 2016
