Nomoreply is waterproof.

And to waterproof completely, by definition has to mean they're not.

I think a decent SBR would actually form a waterproof layer, but it would be very weak mechanically.
The act of troweling on it would compromise it immediately.

That's what I mean, it's not a propper water proof system, might stop a splash but that's about it
