  • A Little Hard
Color: White
The paste came with the top layer already set and hardened, about 1/4 inch. It did have a little hole in the center where I could reach in and remove that top layer, but I was not able to start troweling out the product fresh out of the can like the container stated. Ended up losing about 15% of the product. ... show more

  • repair leak
Color: Black
I was painting my dingy old basement and make it a little more inviting to do my laundry when I notices the concrete steps I had painted two days before with a sealant paint had white water marks. I realized the threshold outside the door had a crack underneath and the water was running behind the stairs. I used this product on the area and repainted the stairs and now I have no more water leaking in! Great product and works as advertised. ... show more

  • It does the job
Color: White
It's very thick and not easily spreadable. It's very hard to work with, but it seems to do the job once you fight with it.

  • Works great, but . . .
Color: White
I used this to seal a large hole in an underground pipe. It worked very well! I resealed it according to the directions, but a month later, the entire jar had solidified. Maybe store the entire container in a sealed plastic bag?
