New generation liquid-applied polyurethane waterproofing membrane (1Κ) DESMOFLEX® PU is the second part of the most complete DESMOFLEX® PU system, that was created by the latest research discoveries of THRAKON laboratories, to offer the ultimate and long-lasting waterproofing. DESMOFLEX® PU system produces a highly hydrophobic membrane that protects, seals and provides excellent UV resistance. The exclusive new generation “DESMOFLEX®” technology gives to the surfaces high whiteness, water vapor permeability, excellent thermal resistance and excellent adhesion for years. https://www.thrakon.gr/en/product/desmoflex-polyurethane/ I have 2 x 15Kg available left over from a job. It’s a thickish grey liquid with fibre that goes on well. Price and postage is for one.
