Works great, easy to apply, economical... what's not to like?
I use this for all the trim in my house. Recently I installed a laminate floor in my guest bedroom, and this caulked worked great to seal the prefinished quarter round and the existing baseboards. It matches the trim perfectly and makes it look like one piece! I also used it for filling in the nail holes as well.
Clean up is easy, since it's water based. Just keep a damp paper towel with you as you work. You don't need any special tools for smoothing it out either. Just a wet fingertip!
Pros: Even Application, Easy to Apply, Good Coverage, Looks Great, Dries Quickly

Review 2 for Dynaflex 230 10.1 oz. Premium Indoor/Outdoor Sealant
I've used this before so I'll give it top ratings, however, I am now using it for a different application. It says 100% waterproof on the tube so I am hoping it will hold up where my laminate kitchen countertop meets the tiled backboard. I read the manufacturer's response on the next page of reviews and they say "water resistant". That's not the same as 100% waterproof. I am hoping it works out as the caulk will get splashed behind the sink and that is the first place the old caulk deteriorated.
Pros: High Quality of Material, Easy Instructions, Looks Great, Dries Quickly

Review 3 for Dynaflex 230 10.1 oz. Premium Indoor/Outdoor Sealant
I've used other cheaper caulk, big mistake. Get this stuff works great, sticks well, doesn't crack or dry out. Even better if you paint over it. It doesn't like constant exposure to water so I don't use it where it could be wet for a long time. In places like that I use 100% silicon but then you can't paint over it and it's even messier to clean up. In any case, don't get the cheap caulk, and if you have someone working for you, don't let them use it either.
Pros: Very Adhesive, High Quality of Material, Easy to Apply, Easy Instructions, Easy to Clean, Easy to Use, Looks Great, Dries Quickly, you can paint over it
Cons: does not replace 100% silicon

Review 4 for Dynaflex 230 10.1 oz. Premium Indoor/Outdoor Sealant
I've used more than 10 tubes over a period of several years. It's relatively easy to work with. The main reason I'm looking for something else is that unpainted on the exterior it becomes very dirty looking. I've also had more cracking than I wish- perhaps other caulk would work no better, but I'm looking.

Review 7 for Dynaflex 230 10.1 oz. Premium Indoor/Outdoor Sealant
Dap 230 was just rated in Journal of Light Construction magazine, May 2013 in an article about caulks and sealants. They said it was "an economical caulk that performed better than most other conventional caulks".
Pros: Economical, top rated

Review 8 for Dynaflex 230 10.1 oz. Premium Indoor/Outdoor Sealant
We purchased a log home/cabin a few months back and were researching for a while which caulk to utilize to seal the seams between the logs.
We picked the "Cedar Tan" color for our project. The ease of use of this caulk even over the expandable foam makes it the "winner" in caulk category. It turns slightly darker in color with exposure to air, so pay attention to color choices and do some trials before conducting similar projects to ours. The logs contract and expand during seasons and this caulk after 6 months on our logs has proven to have the flexibility of silicone in it.
We used it on internal log applications as well - no smell, no issues. Easy to clean-up while it's "fresh." Some thicker applications might take more than a day to solidify, but thereafter becomes somewhat flexible - no chipping or breaking or cracking. The log stain (Deep Mahogany) applies somewhat even and stains this caulk effectively.
Now with our porch is being rebuilt - this caulk is the winner for all winterizing purposes on our log home.
5 boxes = $250 = happy log cabin with no bugs or cold air for YEARS ahead...
Pros: Very Adhesive, Even Application, High Quality of Material, Easy to Apply, Easy to Clean, Easy to Use, Good Protection, Looks Great, Looks High End

Review 12 for Dynaflex 230 10.1 oz. Premium Indoor/Outdoor Sealant
i found this product by accident, now it almost the only caulking i use. once it is cured paint glides on and durability is very good. only minor issue i found is some tubes get air trapped in the tube which causes it to continue oozing out after the task is complete. almost caused a problem first time it happened, but i caught it in time and now know to keep a check on it.

not a waterprrof sealant

This is not a waterproof sealant. "Silicon Tough" is just marketing hyperbole. No silicone.
Cons: not waterproof

Response from Home DepotBy THD-Customer Service, September 5, 2014
Dear Home Depot Valued Customer, We reached out to the MFG for more information and below is their response.
"Thanks for your comments. We're sorry to hear you had a negative experience, but we think we can help clear up some confusion.
As stated on its label, DAP® DYNAFLEX 230® is a premium latex sealant. Its claim of "Silicone Tough" refers to the silicone-like performance of the fully cured latex sealant. When properly applied, DAP® DYNAFLEX 230® has excellent water resistance, which is supported by extensive testing. However, given that DAP® DYNAFLEX 230® is a latex-based sealant, it must be applied in reasonably warm and dry conditions for best performance, as indicated on the product label. Extreme conditions like high humidity or extreme temperatures can impact the product's cure time and, therefore, its performance. Likewise, silicone products may also perform differently depending upon their own application and temperature requirements. (This is actually one of our main topics when it comes to customer service, as users sometimes expect all sealants to behave identically regardless of their application situation.)
Please feel free to contact one of our Technical Customer Service Representatives at 888.327.8477 (888-DAP-TIPS) should you require additional assistance or advice in selecting the ideal sealant for your next job. We'll be happy to help".
