Rated 5.0 out of 5.0 by sdowney717 Very Good caulk, I used on my wooden boat sealing planks
I have an old carvel wood hull with mahogany planks. The OEM linseed oil white putty was badly cracked. I wanted to keep out the rain getting between the planks. So I removed the old putty. I primed with zinsser bulls eye primer the wood. Then I filled the seams with the caulk and smoothed it down with my finger. It shrinks some but that is good as I like seeing the plank edges on the hull. Then I painted white acrylic gloss Behr on top. It holds up, no cracks and no leaks since 2014. And you can sand it wet and dry to smooth the surface.

NEVER BUY THIS!!!!!!!!!!!!!!!!!This is horrible caulk. Takes a super long time to dry clear and as soon as it is exposed to rain it will turn white again and swell up from absorbing moisture. Strange why it is advertised to be a waterproof caulk yet absorbs moisture after it is fully cured. This definitely isn't my definition of waterproof! I use several thousand tubes of caulk a year and never had other caulk behave this way. Contacted DAP and they denied anything was wrong with the caulk after testing the samples sent to them. See picture of caulk samples that was exposed to a few days of rain after it was completely clear.

Rated 1.0 out of 5.0 by Westcreekbill Did Not Meet Expectations.
Thought that this caulk would be a good choice to reseal around windows. Cleaned out old caulk and used 2 tubes to seal and fill minor gaps (less than 1/4"). Four hours later caulk did not form an outside skin. The next day it rained and dissolved most of the caulk. Had to remove caulk, clean it out of the bricks and purchased different product. No where on the tube does it say to not use if rain is in the forcast within 24 hours. Product only states that it should be allowed to dry 2-4 hours before painting. Temperature was in the 80's and 65% humidity. Returned product to Home Depot and explained issue. Home Depot refunded my money with no problem.

Rated 5.0 out of 5.0 by BvilleBound Great 'final layer' sealant for foam board insulation panels
In addition to all of the typical applications for DAP 230, it is an excellent 'final layer' sealant for XPS and polyiso foam board insulation panels. It does not dissolve the foam and remains flexible as assemblies expand and contract each day.
We recently 'wrapped' the outside of a house in Massachusetts with 2" Foamular XPS panels, for example. We sealed all of the joints and edges first with the 'Windows and Doors' version of Great Stuff, which remains flexible. Then we covered all of the joints and edges with a generous layer of DAP 230, to make sure all of the air leaks were well sealed. A couple of photos are attached.
I hope this is helpful.

Rated 1.0 out of 5.0 by JackOh Doesn't last! Cracks!
I used this to seal wanscoting in our 1/2 bathroom. It started cracking in less than a year. Premium indoor/outdoor sealant? I don't think so.

Rated 1.0 out of 5.0 by posser It grows mildew
This would be a great product except it loves to grow mildew. Its a shame because that is the only major drawback but it is a big drawback. Give it a couple of years and you will see your siding and window sills turn filthy grey wherever they have been caulked.

Rated 1.0 out of 5.0 by Marsha paint won't adhere
We replaced siding trim on a back porch exterior with Hardy board and used this caulk to seal all edges and holes. It dried overnight and the next day we painted with Sherwin Williams Emerald exterior acrylic latex paint (very expensive), and it would not cover the caulked areas. Everywhere we caulked the paint bubbled. After painting the caulked areas 4-5 times, the cover was finally almost acceptable. We will never use this product again and are returning what is left to the store.
