Just to try something new I used Bostik Gold Plus liquid membrane on a customer's floor - kitchen and hallway. I might have used Ditra in the past, but I felt comfortable with the liquid membrane in this case - it's over a cork acoustic layer, over a 40-year-old 8" concrete slab in a highrise, that isn't moving anywhere.
For anyone who isn't familiar with it, let's say it's like RedGard, though for some reason I've never liked RedGard.
Well, I laid it down thick, and it dried to a very stretchy, strong, rubbery film. It doesn't get slimy the way RedGard does if you get it wet. It feels as if except for being stuck hard to the cork, it would pull up in one big sheet.
So I'm considering using it in a tub surround. Bostik's marketing claim is that it's appropriate for that use. I haven't used anything but Kerdi in a surround for maybe 10 years, but the convenience of a roll-on membrane is tempting me.
Any comments?

Edit: The materials cost is a little less than Kerdi, but that's not an important motivation.
Edit again: I'm also considering Hydroban for these sorts of applications. Maybe that's where I just ought to go right away.
