How do I apply Aquaseal waterproofing to a wetroom?

Aquaseal is basically a waterproof paint which when set, completely seals the area its on. It can be applied in the same way that paint is applied to a wall. The only stipulation is that it is put on relatively thick, and the installer needs to consider paint brush marks, as if too deep, it may allow water to seep through the seal and onto the eform boards.
