<strong>POLYURETHANE</strong> MEMBRANE DESMOPOL Aplication step by step DESMOPOL membrane has multiple applications and use, on this brochure we detail the most common, however, with these uses must be taken into account all technical aspects of the system for the purpose to reach optimal results, and below it shows the correct way to perform a standard application. 5 4 3 2 1 6 1 Substrate DESMOPOL must be applied on a continuous surface without voids or holes in order to obtain maximum adhesion of the continuous polyurethane membrane. Furthermore, the substrate must be clean, dry and free of contaminants such as dust, oil, grease, paint and other surface treatments. In case of doubt is recommended to test a small part of the substrate. 2 Substrate preparation For best results is recommended to perform the repair of the support by filling voids, holes and levelling the surface. TECNOPOL offers a large range of products to perform these operations. In the case of concrete supports, beside of the mechanical preparation (milling) of the superficial cement layer in order to get open porous surface, It is also advisable to eliminate the feeble concrete and surface defects such as blowholes and voids.
Peripherals and auxiliary: It is important to evaluate and check the status of drains, walls, facades encounters, other next buildings, etc.. to proceed to completion before the application of waterproofing DESMOPOL membrane. Superficial cohesion: during the restoration of tiled roofs, removes all unattached tiles and replace them to keep a flat structure deck, you must also check that the grouting of the tiles is properly executed. If there are previous waterproofing systems should be checked for adherence and remove them in case of being in poor condition. Important: If applied to thin bricks are required placement of a geo-textile mesh to reinforce the waterproofing membrane. 3 Primer use In most cases it is recommended to use a bi-component polyurethane primer as PRIMER-PU 1050 to give better adhesion and to prevent bubble formation. It should be applied by brush, roller or spray equipment (airless), and if necessary a light dusting with quartz sand from 0.3 to 0.8 mm to increase adhesion and mechanical fixation of the next system element. It is essential that the surfaces are in good condition, and fully cured for 28 days (DTU 21 and norm NF EN 206-1). It must have a low vapour transmission (less than 3 lb/24/h./1.000 ft / 2 test method RMA). 7 4 DESMOPOL membrane DESMOPOL can be applied with spray equipment or manually. In both cases the application must be done uniformly. Although it can be applied during a cold, wet weather, it is preferable that the temperature is between 5 ° C and 35 º C and relative humidity does not exceed 85%. In case of use of spray equipment, it must be capable of supplying pressure of 280 bar (4000 psi). In manual applications simply require the use of brush (brush), roller or squeegee. 5 Finishing layer (optional) Once the application of DESMOPOL membrane is made, and preferably before 76 hours from its application, it is advisable to spray one or two layers of aliphatic polyurethane top-coating membrane as TECNOTOP 1C, to obtain a perfect finishing and to ensure the stability of the desired colour. TECNOTOP 1C is also needed on surfaces that require resistance to traffic and to waterproof surfaces that require resistance to chemicals. LIQUID <strong>POLYURETHANE</strong> MEMBRANE
