Not thick but like water. Does not stay on the pipe, flows and dissolves quickly creating very few tiny bubbles which are very short lived. The pump pours the product onto your hand as it sprays, making application awkward. There are much better products out there so you don't have to spend any money on them. I tried this based on the high ratings from other users and the Rectorseal name, but it didn't live up to expectations.
