In response to the reluctant handyman - painting with a primer will not help it avoid picking up debris. Primers all say paint over them in 30 days for this reason - they are very porous (to accept the top coat) and readily collect dirt.

In response to the reluctant handyman - painting with a primer will not help it avoid picking up debris. Primers all say paint over them in 30 days for this reason - they are very porous (to accept the top coat) and readily collect dirt. Much like flat paint, they are also almost impossible to clean without causing burnishing. If you're looking to paint over caulk for cleanliness (and durability), use a satin paint or shinier. The shinier the finish, the harder the finish (and also the easier to clean). Further, latex paint will stay flexible, while oil is liking to crack. Read Less

Based on our experience - if left unpainted and exposed to the sun - it will turn a bit yellowish and will crack. If no exposure to sun - we applied 1.5 years ago and it is still intact (indoor vs. outdoor).

In my exterior application, this product is not drying or skinning. I write this 4-days since the application. If you need something quick-dry, DAP 230 is not the product for you.

Answer: 
If it is hot day, surface dries in a few hours. Next day it is dry. Full cure though can take a week or two. After a full cure it is as a rubber. It can be painted after the surface is dry.

Answer: 
Are you using the colored stuff or the clear? The colored stuff states 2-4 hours before paint. I would give it 24 hours if you could just to be on the safe side.
The clear stuff states 7-14 DAYS. They are not kidding. If you paint it before a full cure the paint will spiderweb and look cracked.

Dynaflex 230 10.1 oz. Premium Indoor/Outdoor Sealant is rated 3.4 out of 5 by 38.
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 1 out of 5 by from Disappointing -- will not dry I purchased this product to caulk exterior gaps. During the application of this product, I was delighted and thrilled. The product feel and texture made working the caulk easy and enjoyable compared to a silicone. However, that initial jubilation and pride in my purchase decision was tamped raw as the product is not drying. Four days since application and the viscosity is no different than day one. The product did not skin and is not drying. Do not use this product. Use a tried and true silicone. The word premium is simply marketing jargon and false. I regret my purchase choice and I dread even more the looming clean-up necessary now to remove this product and use silicone.

Rated 1 out of 5 by from Not good for exterior use in Colorado Big disappointment. Used Dynaflex prior to exterior painting with various gaps and backer rod where applicable. Waited a few days for product to dry. Product did not appear to be cracking after cure time, but within a few DAYS of applying latex paint it began to crack. Regardless of application almost all of it has cracked, especially on the joints of lap siding which it was recommended to be used on. Would not recommend product for exterior use. At least not in Colorado. Only thing worse than paint prep is re-doing the work so soon. Will try Big Stretch and avoid this product in the future.

Rated 5 out of 5 by from Good Stuff I have used about 12 tubes of this stuff to seal up my 54 year old house. It works really well. I have used mostly the gray color as my house is painted gray. I think alot of the bad reviews are based off of people who did not read the instructions. There is a BIG DIFFERENCE between the colored stuff and the clear. The CLEAR TAKES A LONG TIME TO CURE. It states right on the tube, the colored stuff is ready for paint in less than 4 hours, but the clear is 7 DAYS. I have a bunch of tubes left and plan on using this exclusively on my house.

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 4 out of 5 by from I’ve used this product many times over the years and have always had good luck with it. Occasiona... I’ve used this product many times over the years and have always had good luck with it. Occasionally, one of the tubes will get knocked around and crack but that’s on me for dropping it too hard. This caulk always dries in a reasonable amount of time unless it’s an exposed, weather side job in the middle of the rainy season in which case this is probably not the best product to be using since it’s water based. The price point is hard to beat for as good a job as it does.

Rated 5 out of 5 by from Great 'final layer' sealant for foam board insulation panels In addition to all of the typical applications for DAP 230, it is an excellent 'final layer' sealant for XPS and polyiso foam board insulation panels. It does not dissolve the foam and remains flexible as assemblies expand and contract each day. We recently 'wrapped' the outside of a house in Massachusetts with 2" Foamular XPS panels, for example. We sealed all of the joints and edges first with the 'Windows and Doors' version of Great Stuff, which remains flexible. Then we covered all of the joints and edges with a generous layer of DAP 230, to make sure all of the air leaks were well sealed. A couple of photos are attached. I hope this is helpful. Mark

Rated 1 out of 5 by from ABSORBS MOISTURE NEVER BUY THIS!!!!!!!!!!!!!!!!!This is horrible caulk. Takes a super long time to dry clear and as soon as it is exposed to rain it will turn white again and swell up from absorbing moisture. Strange why it is advertised to be a waterproof caulk yet absorbs moisture after it is fully cured. This definitely isn't my definition of waterproof! I use several thousand tubes of caulk a year and never had other caulk behave this way. Contacted DAP and they denied anything was wrong with the caulk after testing the samples sent to them. See picture of caulk samples that was exposed to a few days of rain after it was completely clear.
