Review: Quality caulk - Brown caulk worked just fine no issues
Review: Fills BIG 1/4" gaps in wood siding, no problem. Awesome stuff, easy application - Using old-school white latex caulk on outdoor trim leaves a lot to be desired, namely it shrinks and splits where you need it to seal. Enter DAP Dynaflex. This fills BIG cracks, a bit over 1/4" just made it yawn and say, "can you please give me a challenge?" Flows and applies easily with a caulk gun, and if the label can be believed, stays pliant and won't fail. Time will tell, but so far so good.

### ⭐⭐⭐⭐⭐ Quality caulk

Brown caulk worked just fine no issues

### ⭐⭐⭐⭐⭐ Good color match.
*by C***B on March 28, 2025*

This color, like other DAP colors, was a good match to our wood floor, which was the reason I chose this color of calk. Cure time was not excessive and adhesion was good. I've had good luck with DAP colors in the past and this was no different.
