Customer Reviews

5.5 oz. Dynaflex 230 Premium Indoor/Outdoor Sealant is rated 3.4 out of 5 by 10.
Rated 4 out of 5 by from I would buy again but . . . . I have read comments indicating Dynaflex 230 absorbs moisture after drying, does not dry within the time frame published by the manufacturer, and you cannot apply paint until well after the manufacturer's specified time. OK, maybe some validity to those comments, however, drying time is based upon ambient temperature and humidity, and the moisture content of the surfaces upon which the caulk is applied. If the moisture content of the surfaces is high, and if the temperature is low, and if the humidity is high, the product takes an extremely long time to dry. If the moisture of the surfaces is low, the humidity is low and the temperature is above 75, then the product dries per the manufacturer's specifications. One note of caution. If you use a colored caulk outdoors, and you do not plan to paint over the caulk, do not use this caulk. Even after days and days of drying, if the caulk is exposed to rain the caulk surface will turn whitish. If you apply this caulk under low humidity, warm or high temperature conditions, and the surfaces are pretty dry, and you plan to paint over this caulk, this caulk is great!

Rated 1 out of 5 by from Buyer beware. Read the small print The art work on the tube is the best part of this product. 100% water proof AFTER 7-14 days dry time. That is also on the tube in very small print. How can anyone use this product to seal gutters or siding ?

Rated 5 out of 5 by from My Go to Caulk This is the only caulk I use except for below the waterline on our boat and for concrete work. Indoors and outdoors it works great.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 2 out of 5 by from This sealant is NOT "CLEAR" - until 7 to 14 days later!!! The front product label for this sealant states that it is "CLEAR". The small print on the back of the tube then indicates that "Sealant applies white & dries clear in 7-14 days". The tube further instructs the user to "allow to dry (from white to) clear before painting with latex or oil-based paints". Paintable caulk is traditionally paintable a few hours or so after application. 7 to 14 days is an unbelievably long time to wait before painting. SOOO, if you are a weekend warrior - forget this stuff, because your "honey do list" won't be any lighter until 7 - 14 days later!!!

Rated 4 out of 5 by from Boat Cauking I used this product to seal the transom on a 14ft. aluminum boat transom . It worked great.
Date published: 2017-02-09
Rated 1 out of 5 by from 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.
