MasterSeal NP1 Stone 10.1oz Polyurethane Sealant- Pack of 12 with AWF PRO Gloves. One Component, Flexible, Non Sag, Elastomeric Acoustic Sealant

Used this to seal my new windows on my house. Very thick and works like it should. Sometimes it can be too sticky to get a pretty seam. Even caulking tools don't help. I would wear gloves bc it's hard to get off ur hands.

Just what I expected.

Good price and fast delivery

Why did you pick this product vs others?:take 24 hours to dry, but, get very strong seal

We order from them when our vendor doesn't have any on hand. We got it in a timely manner and it was good. We have gotten some from others that were hard, but this was good NP1. it was a good price and good quality. I will buy from them again.

It is good. I’ve been using it for over 12 years. I use it on aluminum patio covers. That’s my profession when I ordered the 30 pack. It came with a caulking gun, but the caulking gun was missing, but they sent it in separate shipping two days later but overall, my experience with them was good even with the mishap I would recommend them

These is some good stuff
