Hi, I use tempro along all the edges and seams. Then...surprise...surprise....I have found that regular old floor waterproofing paint works great. Applied with a roller. I use battleship grey, a couple coats. I then put down a layer of the same underlayment used for Pergo flooring. Leaving an expansion area along the walls and finally a quarter round. I sometimes use a silicone (horrors!) to hold and seal that quarter round....it makes for easy future maintenance.
