Rated 5.0 out of 5.0 by GrossR Great Item, slows like butter
Purchased this a few months ago. I read the reviews on you need a high compression gun. I am not sure if you have a bad batch. So I put mine in the oven Turned the cold oven on at 300 for about 4 minutes, turn off the oven and put the tubes in. I would say the oven got to about 120. I left the tubes in there about 20 minutes. When I took them out they were warm but not hot.
I applied the products and it flows like pudding. I used the old hand model with ZERO issues. Also, I just used my finger to smooth the product and it wiped off my finger with a paper towel.
I went to paint today and noticed no issues with the caulk, no cracks, just a little dirty from rain the last few months. I will let you know in 10 years if this caulk holds up.

Bonds very well to Metal Roofing, & Brick Cast.
This Urethane product will flex with metal and not peel or crack under climate changes.

I've used this product for years. One if the best on the market for many uses to many substrates. I've read that many people have had troubles getting the product to flow out of the tube. You can't use many of the guns you buy at the stores. It takes a high compression gun, the clicker type will just wreck you hands. It was also suggested to use alcohol to tool it. Do not do this, it will stop the curing process or eat the caulking slowly. It's best to use a little soapy water. Use tape where you don't want caulking and alcohol to clean it up.

Rated 5.0 out of 5.0 by getty3 how to smooth polyurethane caulk
This stuff is really flexible and really good for caulking windows. It is right on par with Valkum caulk. But keep a spray bottle of rubbing alcohol handy when you are applying it. Dont EVER smooth the caulk with your dry finger. It is too sticky for that. but spray a mist of alcohol on it and then smooth it and it works perfectly.

Rated 3.0 out of 5.0 by swannie Wrong color and poor packaging.
The polyurethane sealant is a good product. I ordered 4 tubes of white. I received 4 tubes of grey. It was very poorly packaged. The 4 tubes had a rubber band around them and were shipped in a box twice the size it needed to be with no packing material. Needless to say the bottom of the tubes were pretty banged up. I was able to straighten them enough to work and the color wasn't critical so I didn't return them as the nearest Home Depot is 40 miles. As stated earlier the sealant itself is an excellent product and the price for four was good as well. It does require a very good quality caulk gun to apply.

Home Depot has this product cheaper than going to a local painters store. The only downside is the only color it comes in is white. Overall satisfied.

This stuff really worked well at sealing cracks in cement, and re-caulking our bath tub. Make sure to use a spray bottle with a mixture that is half water and half dawn soap. Soak the NP1 and your fingers in the mixture and smooth out the NP1.

This polyurethane caulk is about the best you can get for adhesion and durability. I've used it to seal exposed cracks in a house foundation and it's held up to several seasonal cycles without a hint of peeling or losing its grip. Highly recommended for those jobs where you want a tough and lasting seal.
