Worked perfectly for what I needed it for.
I used this for the area that my copper pipes came through the floor near my washer. There was also a draft coming in from there. No longer os there a draft, or ants coming in as I have a dirt basement being in an older home in northeast pa, this is ant season here in the spring. They will still find a way up I'm sure. It just won't be there lol. Great product. Easy to clean when still wet. So if you make a mess or put it somewhere you didn't want it, simply wipe it up quick and it will all come up easily.

Speedy delivery
Very pricey for one can but I was told to get it and it didn't last very long at all. Be sure all your areas are prepped before you open it because it sets up quick.

Fire resistant peace of mind.
I have a wood stove in my shop. I use this where the chimney goes through the side wall. I spray it heavy to ensure no sparks escape. Easy to use and lasts longer than the sheet metal chimney pipes. Peace of mind when I have the stove fired up for long periods.
