Stef-Tek RLX is a liquid waterproofing membrane. Its all-acrylic polymers give it the water and air barrier properties, which waterproofs the substrate.
Unlike Stef-Tek, Stef-Tek RLX has a more liquid consistency, which makes it easier to apply with a roller.
Stef-Tek RLX is also used as an adhesive for polystyrene panels.
