I have a gap of around 1/2 inch between a newly installed tile entryway and the door. this is sitting on a slab foundation. Would I be able to use this to seal that 1/2 inch, to preven moisture intrusion into the surrounding wood floor (the reason the tile is there instead of wood now)? The other option I was looking at was closed cell foam backer rod with caulk over that. Would like the simplest option that still works. quarter round will be placed over the finished product. Thanks!

10.1 oz. Dynaflex 230 Premium Indoor/Outdoor Sealant is rated 2.7 out of 5 by 23.

And I used it on a horizontal surface, still hard to control. Also, it is not a dark brown as the tip color indicates. It is closer to the color of chocolate milk.

Rated 4 out of 5 by from I would buy again but . . . . I have read comments indicating Dynaflex 230 absorbs moisture after drying, does not dry within the time frame published by the manufacturer, and you cannot apply paint until well after the manufacturer's specified time. OK, maybe some validity to those comments, however, drying time is based upon ambient temperature and humidity, and the moisture content of the surfaces upon which the caulk is applied. If the moisture content of the surfaces is high, and if the temperature is low, and if the humidity is high, the product takes an extremely long time to dry. If the moisture of the surfaces is low, the humidity is low and the temperature is above 75, then the product dries per the manufacturer's specifications. One note of caution. If you use a colored caulk outdoors, and you do not plan to paint over the caulk, do not use this caulk. Even after days and days of drying, if the caulk is exposed to rain the caulk surface will turn whitish. If you apply this caulk under low humidity, warm or high temperature conditions, and the surfaces are pretty dry, and you plan to paint over this caulk, this caulk is great!

Rated 1 out of 5 by from Thankful First time I tried this product was around the base of an outdoor light fixture. It cracked in a couple weeks. Fast forward a few years. This product was applied around a kitchen sink. After 24 hours it just peeled off entire sink perimeter. I'm just thankful I've never used it for window installs.

Rated 1 out of 5 by from Buyer beware. Read the small print The art work on the tube is the best part of this product. 100% water proof AFTER 7-14 days dry time. That is also on the tube in very small print. How can anyone use this product to seal gutters or siding ?

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.
