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.

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! : )

I couldn't use the product because it was dry. It has good quality but be sure seller doesn’t send you old product.Otherwise, like me, you will throw it away without using it.

It just seems that every time I use it it's pretty stiff and if you're using a handcocking gun you really have to pull on it if you have a power caucker it'll be okay

Caulk worked just fine

Obviously, this is a quality product based on reviews. However, if you're a novice at applying caulk, I highly suggest you skip this product. The first challenge is trying to get the product to come out of the caulk gun. Left in sun for two hours, no luck. The tube finally burst and then the real fun began. It has the consistency of chewing gum. I ended up applying and smoothing out with my finger. The end result was NOT a pretty caulk line but a messy one. I'm sure a professional caulker could apply this product easily if they're able to get the product to come out of the tube, but not an amateur. In a nutshell, if you enjoy playing with sticky chewing gum, this is your jam!

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.

El producto estaba completamente tapado de la parte superior, una vez hecho el corte en el aplicador y utilizando una pistola de presión, el contenido no salía, después de aplicar demasiada fuerza, apenas logró moverse y comenzó a salirse por la parte de abajo.

Used this on an unusual application on nylon felt. Good grip strength. Bonds to glass really well too - by accident. It would be nice to have this come with a wire to rupture the membrane at the base of the nozzle - or a shorter nozzle - it is too long for any commonly available nail to reach.

I used it on my smooth cement garage floor with cracks anywhere from very thin 'spider' to an inch and this stuff fills them all. It's very easy to work with a caulk gun and spatula, not too thin nor thick. Since many of the larger cracks were deep I had to go over them a second time using much less. I did it in warm summer weather and it still took a few days to 'dry' and after a week or so it was hard yet with a very slight flex. It drys with a slight sheen and a color pretty much as shown on the tube. I can tell paint will adhere to it with no problem. I feel really confident it will last a very long time.
