Dap 7079818816 18816 Polyurethane Construction Adhesive and Sealant, 10.1 oz, Black

Bought 2 tubes actually. I had to plug up a few dozen holes in the floor where lag bolts used to be. This stuff worked GREAT!!! - after I figured out that the hole and floor around it had to be clean - which is what I would have known if I read the instructions first.These holes are in a floor that has been treated with an epoxy coat, so it was important to sweep, brush hole with wire tooth-brush tool, and wipe away all the fine dust with a damp cloth. Next day I plugged the holes with DAP and calk gun. Needed some good grip strength to work the caulk gun. It gets easier as the tube empties out. I FORGOT a putty knife to make the plugs flat to the floor with a little bit of a collar around each hole for sealing. Greg cardboard worked fine.Set up was about a day, and 3 days later we were moving stuff over the holes and the DAP held in fine. I like this stuff, and probably will tend to buy it if I need it here again or at home. It is a little more expensive than some of the other products, but it is worth it for its durability. Oh, it was a little smelly during application, but smell was gone the next day. ThankS! : )

Work great on my repair on my leaking roof rack. Great buy for sure. Drying time is very fast!

I did a lot of research and settled on this product to complete the project I was performing. I have a cinder block home that has stucco over it then painted. There seems to be a shift in the foundation over the years and there were numerous cracks on the outside walls. While I new this profuct would not hold my house together, not only do the cracks look bad, but water and bugs could get inside the walls.I read the directions and put on some rubber gloves since this stuff is heck to get off your hands, and basically ran a bead of it on top of the cracks then pushed it in and smoothed it around to blend in with the stucco. It says to wait 7 days to paint over it with no primer needed. I painted over it in 7 days and it looks professionally done.I would buy this product again if needed.

Better than gorilla glue. No foam residue. Project looks great.

If you are looking for a super durable waterproof caulk this is the real deal. Not sure why but neither of the two big box home improvement stores carry it. I’ve used it for caulking around windows and doors as well as areas where concrete butts up against wood ( sidewalk and patio areas). It’s very sticky when you apply it. When this stuff dries and cures, it becomes very firm but still flexible. Its consistency is like a hard rubber. Very durable.One minor heads-up - The stuff is very difficult to squeeze out of the tube with a caulk gun. You would need the hand strength of an adult Orangutan to do it. I ended up using a heat gun to warm it up so it was easier to apply.

This was a huge disappointment, once I snipped the tip and tried applying it I noticed it was hard as a rock inside the tube! What a waste of money! I’m afraid of ordering this type product again for fear it’s going to be hardened in the tube like this one was.

This is a high quality sealant. As some reviews stated it is somewhat harder to get out of the caulking gun than latex or silicone caulk but you can get it to work correctly with a good quality caulking gun. I will purchase this again for use on metal roofing.
