What is the difference between Lavasteen and microcement?

“Lavasteen is a trowel-applied epoxy compound 1–2 mm thick, fully waterproof in itself and suitable for heavy-duty floors. Microcement is a thin mineral layer of 1–2 mm whose waterproofing depends on a PU topcoat — ideal for walls. We often combine them: microcement on the wall, Lavasteen on the floor.”
