Exactly what I needed

This is exactly what I needed to fix a plumbing issue. I'm using this as at temporary fix for filling in a large gap between the bath faucet and wall to prevent water from running into my wall. This didn't come with instructions and if they were written on the individual packets it was done in Chinese. No pretence, this is a made in China product. I watched the videos to figure out how to best apply it. It dried beautifully. I admit that I applied it then left it be for about a week as it's in my guest bathroom it's not used often. I used two packets to fill the gap and another half when I went to check because there was a little gap in the putty. That fill was a cosmetic fill. This is a great product and way cheaper than a plumbing service. Read more
