Rated 3.3 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 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
Rated 3.0 out of 5.0 by Not too "Brown" I used this to re-caulk around a screen door frame after adjusting it. It went on fine, and the color shown on the nozzle was an exact match for the frame. But after a couple of days of curing, the caulk itself is much lighter and much more red than the advertised brown. Just as well it's paintable... :-) January 20, 2016
Rated 1.0 out of 5.0 by Not waterproof, do not use in a shower I recently completed a tile walk in shower. My grout was brown so thought I would use this caulk in brown to caulk around the Kohler glass doors I purchased from Home Depot. I caulked the bottom track both inside and out with this product. Let it dry 2 days before using the shower and noticed a leak. Come to find out the caulk on the shower side of the lower track turned to a brown gue. Now I need to clean all this out let it dry and will use a silicone caulk not a latex like this product. Product says it is waterproof, but is not. Do your self a favor and use a silicone caulk like that made by GE. When that stuff dries it is really waterproof. December 24, 2012
Rated 5.0 out of 5.0 by The best latex caulk I have ever used I have worked in the building trades for 36 years. This is one of the few products I have used that I can say is truly excellent in every way. On a wood to wood exterior application this stuff holds up for years if you cover it with a coat of paint to block the UV rays. It does not crack or shrink. I have gone back to do rework on jobs years later and the Dynaflex 230 still looks new with NO failure what soever. The low ratings of this product are unfair because it seems those folks did not know what they were buying for a job that required a different product. June 6, 2013
Rated 5.0 out of 5.0 by Excellent weather resistant paintable caulk DAP 230 caulk is very easy to apply and tool to a smooth finish, much better than silicone or urethane caulks. I've found it bonds well to painted and unpainted wood, metal or PVC with no problems and it takes and holds paint very well because it has no silicone in it - just be sure to let it dry completely first and use a backer rod for a deep joint. Silicone isn't listed as an ingredient on the back label, and anyway silicone caulks aren't always the best answer to every caulking problem. October 26, 2012
Rated 1.0 out of 5.0 by I am worried that it won't dry I applied this to roof flashing 3 hours ago, and also put a test bead inside on cardboard. It is very thin, and the color is not mixed well. There are streaks of light brown and darker brown. But I am worried that it will not dry. The tube says it will dry and be ready to paint in 2 hours. It is 3 hours and the stuff has not even skinned it has not dried at all!!! October 20, 2013
Rated 5.0 out of 5.0 by It is smooth to use. Product is easy to use and flows well. Easy cleanup. March 11, 2014
Rated 1.0 out of 5.0 by misleading labelling/pricepoint I went to my local home depot to purchase a 100% silicone outdoor sealant, what most mfrs sell as their premium lines of sealant. This is labelled as Premium, and I purchased this, but would not have had it been upfront and stated anywhere on its label it was a LATEX based product. It does not, even in the fine print. Its price point is similar to other mfrs' all silicone sealants. I think they are purposefully being dodgey about its content because they know people wouldn't pay this price for an all Latex product- whch typically sell for half the price. It's going back to the store in the morning, and I'm sure as usual Home Depot will exchange it for something suitable with a smile. The only thing the marketing dept of DAP sold me today was a pledge to myself to not buy products from shady companies thinking consumers are too dumb to notice an inferior grade product sold as premium is more than just a label.
