It is suitable for interior and exterior work, including use as a moisture-barrier filler beneath reactive resin coatings. A thickness of at least 3 mm provides protection against moisture penetrating from the substrate within the specified system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThis item is the Nafufill EC 6 powder component in a 20 kg bag.
