Answer: 
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 Read More
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

Answer: 
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).

Do not, however, leave tubes out in the hot sun for hours while you work. They can quickly exceed the maximum 120 degree temperature and the sealant

Answer: 
Dear Josh: Yes. DAP 230 is an excellent, long lasting sealant. We use it for all of our residential work, to seal windows, doors, etc. Just make sure the surface is clean. We ran into a problem with one brand of fiberglass windows, and discovered that there was a light film of oil on the surface - probably left over from the manufacturing process.
I hope this is helpful.

Rated 3.7 out of 5 by 31 reviewers.
Rated 5.0 out of 5.0 by Very Good caulk, I used on my wooden boat sealing planks I have an old carvel wood hull with mahogany planks. The OEM linseed oil white putty was badly cracked. I wanted to keep out the rain getting between the planks. So I removed the old putty. I primed with zinsser bulls eye primer the wood. Then I filled the seams with the caulk and smoothed it down with my finger. It shrinks some but that is good as I like seeing the plank edges on the hull. Then I painted white acrylic gloss Behr on top. It holds up, no cracks and no leaks since 2014. And you can sand it wet and dry to smooth the surface. couple pics. and link to album https://photos.google.com/album/AF1QipM_ikHu-OwBivAYqVMNCBAor2mAiPa6uDp7fQcD February 18, 2016
Rated 1.0 out of 5.0 by 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. January 21, 2016
Rated 1.0 out of 5.0 by Did Not Meet Expectations. Thought that this caulk would be a good choice to reseal around windows. Cleaned out old caulk and used 2 tubes to seal and fill minor gaps (less than 1/4"). Four hours later caulk did not form an outside skin. The next day it rained and dissolved most of the caulk. Had to remove caulk, clean it out of the bricks and purchased different product. No where on the tube does it say to not use if rain is in the forcast within 24 hours. Product only states that it should be allowed to dry 2-4 hours before painting. Temperature was in the 80's and 65% humidity. Returned product to Home Depot and explained issue. Home Depot refunded my money with no problem. July 14, 2016
Rated 5.0 out of 5.0 by 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.

Rated 5.0 out of 5.0 by Best latex caulk on the market Amazing flexibility, stretch and adhesion. Meets 920 spec. For Windows, doors and siding July 28, 2016
Rated 1.0 out of 5.0 by Doesn't last! Cracks! I used this to seal wanscoting in our 1/2 bathroom. It started cracking in less than a year. Premium indoor/outdoor sealant? I don't think so. January 28, 2016
Rated 5.0 out of 5.0 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 1.0 out of 5.0 by It grows mildew This would be a great product except it loves to grow mildew. Its a shame because that is the only major drawback but it is a big drawback. Give it a couple of years and you will see your siding and window sills turn filthy grey wherever they have been caulked. March 10, 2016
