NP1 10.1 oz. Gun-Grade Polyurethane Sealants (4-Pack) White is rated 4.3 out of 5 by 16.
Rated 5 out of 5 by from Great Product Bonds very well to Metal Roofing, & Brick Cast. This Urethane product will flex with metal and not peel or crack under climate changes.

Rated 5 out of 5 by from Great product 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 out of 5 by from 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 5 out of 5 by from Great Product 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.

Rated 5 out of 5 by from Tough caulk for tough jobs 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.

Rated 3 out of 5 by from 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.

Rated 5 out of 5 by from Do the Tighten Up! A masonry contractor who tuckpointed my home used this caulk to seal joints around windows, doors and concrete flatwork that touched up against stone and mortar. I bought more to do more caulking work and tighten up my home for winter. This stuff is simply awesome. It dispenses in a standard caulk gun and sets up in about 24 hours. Once set, it moves and flexes with the joint but maintains an airtight seal. Whatever color you choose (Home Depot usually just has white) it will mellow as it ages, blending into your home over time. I would warn users to use rubber gloves when handling this caulk, however. It is not for the novice DIY-er. The material is very tacky and difficult to remove, even with soap and water. Be careful!

Rated 5 out of 5 by from Best caulk for Stucco, exterior doors and windows This is a very strong caulk, that will last to seal gaps in stucco, between doors, trim and windows. Please note, It will not peel out easily like a silicon caulk.
