How long does this caulk need to dry?

I am needing to seal an egress window and want something that is quick drying; some of the products on the market take 7-10 days and this is too long to wait.
Asked by: peat14
In my exterior application, this product is not drying or skinning. I write this 4-days since the application. If you need something quick-dry, DAP 230 is not the product for you.

Waiting time to paint with latex paint on dynaflex230?

Asked by: Mack
Are you using the colored stuff or the clear? The colored stuff states 2-4 hours before paint. I would give it 24 hours if you could just to be on the safe side. The clear stuff states 7-14 DAYS. They are not kidding. If you paint it before a full cure the paint will spiderweb and look cracked.

Dynaflex 230 10.1 oz. Premium Indoor/Outdoor Sealant is rated 3.5 out of 5 by 41.
Rated 5 out of 5 by from Good Stuff I have used about 12 tubes of this stuff to seal up my 54 year old house. It works really well. I have used mostly the gray color as my house is painted gray. I think alot of the bad reviews are based off of people who did not read the instructions. There is a BIG DIFFERENCE between the colored stuff and the clear. The CLEAR TAKES A LONG TIME TO CURE. It states right on the tube, the colored stuff is ready for paint in less than 4 hours, but the clear is 7 DAYS. I have a bunch of tubes left and plan on using this exclusively on my house.

Rated 1 out of 5 by from Disappointing -- will not dry I purchased this product to caulk exterior gaps. During the application of this product, I was delighted and thrilled. The product feel and texture made working the caulk easy and enjoyable compared to a silicone. However, that initial jubilation and pride in my purchase decision was tamped raw as the product is not drying. Four days since application and the viscosity is no different than day one. The product did not skin and is not drying. Do not use this product. Use a tried and true silicone. The word premium is simply marketing jargon and false. I regret my purchase choice and I dread even more the looming clean-up necessary now to remove this product and use silicone.

Rated 5 out of 5 by from 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.

I put in two windows and three sliders in dry weather at an ambient temperature of 60 degrees. It was dry for three days. When it rained on the fourth day, the caulk turned into a gooey, milky substance that dissolved.

I’ve used this product many times over the years and have always had good luck with it. Occasionally, one of the tubes will get knocked around and crack but that’s on me for dropping it too hard. This caulk always dries in a reasonable amount of time unless it’s an exposed, weather side job in the middle of the rainy season in which case this is probably not the best product to be using since it’s water based. The price point is hard to beat for as good a job as it does.

It is totally awesome. I agree with the previous poster that most negative reviews are from those missing the instructions on the bottle of clear DAP. I always use white and it is dried and ready to paint within 4 hours, probably less. I use this all over my house and it has never failed me.

Rated 4 out of 5 by from All purpose sealant that works I've been using this product for a general purpose sealant for at least 5 years and have been very pleased with its performance against the weather conditions in Florida. I would recommend this product anytime for general construction

Rated 1 out of 5 by from Dynaflex 230 Caulk I used this caulk for raw wood trim and a wood surface in 60 degree weather. After several days this caulk is still not dry. Now I have to remove it and recaulk with another product. This is awful!
