DAP 3.0 Window, Door, Trim & Siding High Performance Sealant is ideal for sealing windows, door frames, corner joints, siding, trim, butt joints, baseboards, molding, pipes, ducts and vents. It is paintable in just 30 minutes which helps complete the job faster and saves time. In addition, DAP 3.0 is 100% waterproof and is water resistant in 30 minutes which reduces the risk of ruining the project by getting the sealant wet too early from incidental rain or water contact. For exterior projects, you can seal up gaps and cracks just 30 minutes before rain is forecasted. Also, DAP 3.0 offers extreme temperature use so it can be applied in temperatures ranging from 20-degrees Farenheit to 120-degrees Farenheit. DAP 3.0 is shrink and crackproof; plus, it adheres to just about any surface like wood, metal, brick, glass, vinyl, aluminum, concrete, masonry, plaster, drywall, stucco, stone. DAP 3.0 also works on surfaces that silicone just can't adhere to like painted surfaces and oily woods.

Rated 4.3 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by You definitely get what you pay for here! I applied this with extreme ease on two exterior vents on my home, temperature was 24 degrees out and application was simply perfect. Nice clear finish and it only took 1/2 the tube to go around both 1.5 ft by 2.5 ft vents and I was generous with the use. February 27, 2015
Rated 4.0 out of 5.0 by DAP has another winner. DAP has another great product for sealing out the outside. It went on smooth and easy. This one though you can unscrew the tip and clean it out. Then put a piece of plastic wrap on and screw the tip back on to keep the caulk from drying out. I thought that it took more effort to squeeze the caulking gun's trigger than some of the other DAP products that I have used. When I took the tube out of the caulk gun, it the plunger didn't want to come out. I had to force it. There may have been a slight flaw in the tube that could not be seen or felt that made it bind slightly both pushing the caulk out of the tube and removing the plunger. That's why I'm giving it only a Good overall rating. January 30, 2014
Rated 5.0 out of 5.0 by Performs As Expected DAP makes a good product. I have used many of their sealants for indoor and outdoor use in the past and I have been happy for the most part. This product is no different. Some of the reviewers have noticed that the sealant comes out of the gun a little stiff, I did not notice that. I thought it came out easy with a nice bead that was easy to apply. It dried fairly quickly and is paintable. I cannot speak to its longevity over several years or how mold resistant it is, 2 factors that would highly influence my opinion of this product, however, my initial reaction is to recommend it.

Rated 5.0 out of 5.0 by Quality You Expect DAP has been around a long time. This is the same quality product I've come to expect from them. Easy to use. Long lasting and dependable. Just finished the whole house. I'm set for a few more years. It seals great. Looks great and easy to clean up. September 3, 2014
Rated 4.0 out of 5.0 by Great quality, a little hard to get out of the tube This stuff is great - it dries super fast, it's paintable, shrink proof, pretty much exactly what you're looking for in a caulk. I agree with the other reviewers that it can be a little difficult to get out of the tube. That leads to a little "blobbing" and over application if you apply too much pressure, but if you prepped correctly by applying painters tape above and below the caulk line it's kind of a non-issue. I put the tube into my brother's cordless caulk gun and it didn't even bat an eye at the extra resistance - so pro's probably won't even notice, but DIY's might. February 28, 2014
Rated 5.0 out of 5.0 by It's DAP! I love it! I've been using DAP products for a long time and never have a problem with them and this one is no exception. I love the quick dry time and ready to paint time (I'm impatient - LOL). I find it hard to add to the writ-up that HD has for this; it really is good. Just follow the directions and you'll be as pleased as I am. January 11, 2014
Rated 2.0 out of 5.0 by impossible to get a clean line this is the most difficult caulk I have ever used. it takes a lot of pressure just to get it to come out, then it is almost impossible to get a nice bead. you have to keep paint thinner next to you just to keep it clean. September 25, 2013
