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
