2. INTRODUCTION More than 25% of the existing housing moistures are originated on the roof. Mainly caused by the lack waterproofing solution or the failure. A roof is a protection element exposed to atmospheric agents (rain, ice, snow, solar radiation, pollution, etc.) Barcelona, 20/08/2011

3. ROOF TYPES Following its shape: Flat or bent skirt, flat or pitched, simple or double bent, etc. Following its constructive elements: Homogeneous (one layer), heterogeneous (multiple layers) Following its protection or finishing: Concrete, tiles, stoneware, panels, etc. Following its uses: Trafficable (not vehicular), non trafficable or green roofs. Barcelona, 20/08/2011

4. WATERPROOFING TYPES The most important characteristic from a waterproofing system is its sealing power against atmospheric and pollution agents. Most common types: Waterproofing sheets (bituminous or synthetic) Metal sheets (folding and moldable) Metal deck- Metal panels Big elements with sealed joints Overlap elements (tiles, slates) Liquid ( bitumen emulsions, acrylic emulsions, epoxy, PU, polyuria, etc.) Barcelona, 20/08/2011

5. PATHOLOGICAL AGENTS RAIN WATER CONDENSATION OR DEW HAIL WIND FREEZE-THAW SOLAR RADIATION POLLUTION Barcelona, 20/08/2011

12. APPLICATION Application method : roller, brush or airless spray. Dilution : 0 to 5% Diluent and cleaning : Water Repainting time: 12 - 24 hours at 20º C –Can be repainted after cleaning the existing coating as much as needed. Application conditions: Working temperatures must be above 10 °C and below 35 °. RH below 80 %. Temperatures of support and coating must be within the application conditions too. Barcelona, 20/08/2011

13. APPLICATION Support : The concrete structures must be cured for 28 days. The surface to be treated should be clean of grease, oil, curing chemicals, dust and dirt. IMPERTEXSA can be applied directly on wet substrate following sealing procedure. Eliminate surface irregularities. Do not apply on loose, dusty, unclean substrates which are unacceptable to receive the coating. If required use mechanical or manual tools to clean the support. Resurface and seal the cracks with polyurethane caulk, reinforced with ROOFTEX FLEECE 80 wherever necessary. Treat the expansion joints (according to standards) and seal with polyurethane caulk. Barcelona, 20/08/2011

14. APPLICATION Support : We recommend using a thin geotextile interlayer to control the film thickness and uniformity. Sealing: Apply on layer of IMPERTEXSA CUBIERTAS 20% diluted with water. Drying time 2 to 4 hours at 20º C. Finishing: Apply two layers of IMPERTEXSA CUBIERTAS without diluting. Drying time between layers is 12 hours. Barcelona, 20/08/2011

15. PRECAUTIONS Dont apply IMPERTEXSA CUBIERTAS if rain is forecasted during drying time, on cloudy days or during maximum insolation hours. Drying time and repainting time may vary following weather conditions. Apply on surfaces with enough slope to avoid stagnant water. This product is not recommended for trafficable areas, although temporary pedestrian accessibility is allowed for maintenance jobs. Barcelona, 20/08/2011

16. PRECAUTIONS Avoid direct exposition to sun of the containers. For a correct waterproofing, we recommend to cross layers between first and second hand, reaching a better distribution of the coating and correctly regularize the consumption. On roof waterproofing, parapet (walls) must be painted with a minimum high of 15 cm. Dont use brackish water, chemically polluted, cloudy or calcareous in excess. It could be alter the product properties. Storage of the containers must be protected from frost, prolonged exposure to sunlight and high temperatures. Barcelona, 20/08/2011

17. PACKING 20 and 5 kilos drums. Colors: White, blue, red, terracotta, green and grey. Recommended maximum storage time: 1 year at 25 º C in their respective containers. Barcelona, 20/08/2011

18. SAFETY Water based product. Each container has a safety label with instructions that must be observed. National an local safety regulation must also be respected. Avoid inhalation of vapor or direct contact of the painting with skin and eyes. If applied on enclosed rooms, force ventilation is required. Use personal protective equipment..
