mer and keeps it watertight in the winter. Consequently, it also contributes to the reduction of energy consumption for cooling or heating. • It reduces the danger of moisture concentration to the substrate and consequently the creation of mold, because it is vapour permeable. • Ideal waterproofing solution for surfaces with installed (or to be installed in the future) photovoltaic modules. • It maintains its whiteness and does not chalk. • It cleans easily only with water. APPLICATIONS DUROSTICK DS-220 is applied with ease on terraces and roofs to be covered with clay roof tiles, on roof corners and ridges, on lead lined roof valleys, balconies and built-in planters. It is recommended for substrates made from concrete, terrazzo, for wood surfaces, existing asbestos-based mortars, cement boards and well-adhered asphaltic-based roofing material. USE Preparation of cementitious surface without any waterproofing: Using a stiff broom and water, thoroughly clean any loose sections, dust and mud. Remove any black spots using DUROSTICK D-95 CLEANER or a bleach - water solution, at a dilution ratio of 1:1. Continue by thoroughly rinsing with plenty of water. Surfaces to be waterproofed must be dry and should not get wet for the next 24 hours, in order to avoid surface moisture from being trapped. • Capillary water absorption 0.01kg/m2.h0,5 (EN 1062-3, requirement EN 1504-2: w <0.1) • Permeability sD to CO2, per EN 1062-6: sD > 50m • Water vapour permeability: sD per EN ISO 7783: sD = 1.17m (water vapour class I, sD <5m) • Adhesion to concrete per EN 1542: 1.2 N/mm² (requirement for flexible systems FOR ROOFS, BALCONIES, BUILT-IN PLANTERS
