PROPERTIES Acrylic, elastomeric and solvent-free waterproofing product for roofs. It creates a uniform, impervious to water membrane, without seams nor joints. It perfectly covers hairline and micro cracks, while it prevents their reappearance. It maintains its flexibility at temperatures ranging from -20°C to +80°C. It does not allow for the creation of moisture related problems due to any future expansion and contraction of the coated surfaces. Certified by the University of Athens (Department of Physics, Division of Applied Physics), as ‘Cool’ material of low thermal conductivity and high reflectivity. Its brilliant white color significantly reduces the heat absorption from the roof slab and improves its energy efficiency. Classified as product for surface protection of concrete surfaces per EN 1504-2. APPLICATIONS DUROSTICK No39 easily applies on terraces and roofs to be lined with clay roof tiles. It is also suitable for corners, edges and lead lined roof valleys. Great for spot crack sealing. USE New surface preparation: Using a stiff broom and water, thoroughly clean any loose sections, dust and mud. Remove all black spots (mold/mildew) using DUROSTICK D-95 CLEANER or a bleach - water solution, at a dilution ratio of 1:1. Follow by rinsing thoroughly 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. Preparation of surfaces coated with waterproofing product(s): •Detached torch-down roofing: Remove them using a wide roofing scraper and roofing torch. •Well adhered existing torch-down roofing material, only require a first coat of No39, diluted 5% with water and a second, crosswise coat undiluted to complete the waterproofing. TECHNICAL SPECIFICATIONS: • Density: 1.45±0.05kg/lt • Elongation at break, (per ASTM D 412): After 8 days of curing and at 1mm thick membrane, the elongation at break was determined at 300% • Full tightness: 7 Atm per DIN 1048 • Capillary water absorption: 0.01kg/m2. h0,5 (EN 1062-3, requirement EN 1504-2: w< 0.1) Acrylic elastomeric waterproofer for flat roofs 39 Νο
TOOLS FOR THE REMOVAL OF DETACHED ELASTOMERIC WATERPROOFING PRODUCTS •Remove detached or deteriorated elastomeric waterproofers, removed with the help of a sharp metal blade and pliers. •Detached elastomeric materials that are not visible, can be found using a garden hose. Pour water on the roof surface from about 1 meter high. Notice the change of the sound the water makes when it hits the detached sections of the waterproofing and mark them. Cut the detached sections using a razor blade and scrape the defective material off. Application: Using a roller, first apply the micromolar stabilizer, AQUAFIX undiluted, or the SOLVENT BASED PRIMER, diluted 30% with THINNER 101 of DUROSTICK. Alternatively, dilute No39 with water, at a ratio of 1:1 and use it as a primer, assuming that the roof does not have any deteriorated sections. Once the priming product dries, locate any possible hairline cracks (0.1-0.4mm width). Individually coat each crack with one-two layers, to seal them completely using the product undiluted. If the width of the cracks is between 0.5-1mm, it is recommended to seal them using the DUROSTICK ACRYLIC CAULK or the elastomeric sealant, DS POLYMER of DUROSTICK, using a putty knife. Continue by applying two coats of undiluted No39 over the cracks to complete their sealing. Complete the surface waterproofing by applying two undiluted coats over the entire area using DUROSTICK No39. Apply the second coat crosswise to cover any minor substrate imperfections, once the first one is completely dry and walkable. • 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: 1.0 N/mm² (requirement for flexible systems without circulation: 0.8 N/mm²) • Impact
NOTES •Stir well before use • Avoid the application of the waterproofer when there is a possibility of rain within the next 24 hours. resistance per EN ISO 6272-1: 10Nm (class II) • Application temperature: From +8°C to +30°C • Temperature resistance: From -20°C to +80°C Laboratory testing by the Ministry of Environment & Buildings (ΚΕD Ε 1580/243). • An excellent quality and durability elastomeric waterproofer that ensures for many years the sealing of the surfaces. • Offers satisfactory walkability. • Perfectly seals capillary cracks of the substrate, prevents them from reappearing, thus preventing the penetration of moisture into the coated substrates. • Presents great durability against standing water remaining on its surface. • Ideal solution for waterproofing surfaces where photovoltaic modules have been or will be installed. • Maintains its properties from -20°C up to +80°C. • Maintains its whiteness and does not chalk. • Recoated easily, ensuring permanent waterproofing. • Cleans easily, only with water. • Ideal value-for-money product.
