Easy to use product. Clean line and fast drying. I made sure shower was completely dry before using and 24 hrs of drying. That was my personal decision. Product was dry in time it stayed.

The seal on this product was extra hard to puncture!! I had to use a hammer and nail!! That said, it was perfect for sealing my tub.
