Microl 2000 – heavy duty membrane system with fiberglass matting
- CAR PARKS
- WATER FEATURES
Microl 2000 is a high performance, attractive and durable membrane coating which is easy to apply. Typical solution applications are for roofs, parapets, walls, car park decks, ramps, balconies, plant rooms, gutters and wet areas.
Microl 2000 has been specially formulated to provide a seamless membrane which bonds to a variety of substrates when applied according to directions. Its resilience remains stable over a large temperature range and allows for considerable movement in bridging developing cracks. Microl 2000 offers excellent sag resistance and filling characteristics at specified coverage rates and is ideal for both horizontal and vertical surfaces.
Microl 2000 system provides excellent weather, chemical and mechanical damage resistance due to its high build, high solids characteristics. It is relatively unaffected by exposure to UV light, will withstand ponding water and is resistant to mould, mildew and microbiological attack. Microl 2000 can be specified for use in new structures as well as for the maintenance of existing structures. Microl 2000 may be used on its own or combined with reinforcing fabrics to provide systems suitable for a variety of applications including building roofs and car parks.
All substrates must be sound, dry and free of dirt, oil, grease and other contaminants. Defects must be made good to give a smooth surface. New concrete must cure a minimum of 28 days. New brickwork and render must be left for 7 – 14 days
Expansion joints must be treated as such and a suitable caulking compound applied. Moving cracks and cracks in excess of 2mm wide need to be filled with a suitable caulking compound after removing any loose material. Shrinkage cracks and minor non-moving cracks need to be pre-filled with Microl 2000. Penetrations and vertical walls. A coved cant strip (minimum 12 x 12mm must be formed with a suitable caulking compound to support the Microl membrane where a change of plane occurs.
Most surfaces require priming immediately prior to the application of Microl 2000. Acrylic primer (Adchem No.19378) for concrete and unglazed tiles. Solvent primer (Adchem No. 19374) for concrete and bituminous felts. Metal primer for metals. Alternatively prime porous surfaces using MICROL 2000 diluted; 1 part to 2 parts water, allow 1 hour to dry.
Apply first coat of Microl 2000 to a small area to receive reinforcing mat. While still wet embed the reinforcing mat in the Microl 2000 with a dry roller or brush. Apply a further coat of Microl 2000 to the top surface to ensure the mat is completely saturated and no air is entrapped in the system. Coverage 1lt per m². Allow to cure 24 hours. Apply a final coat. Coverage 0.25lt per m². Total coverage 1.25lt per m².
Microl 2000 will withstand ponding when fully cured. However application must not be started if rain is expected to commence within 12 to 24 hours. Ponding must be carefully removed within the first 4 days to prevent possible damage. Re-coat damaged sections when dry.
Water borne membrane products must be allowed to cure completely and in depth prior to the application of tiles or similar products. Because environmental conditions fluctuate it is impossible to be concise when forecasting the curing time of the membrane. A minimum of 7 days must be allowed for external applications in cool, humid or wet weather. Lack of complete curing may result in the membrane re-emulsifying under paving. Tile and other paving mediums may be laid over the cured Microl. It is essential that the membrane is thoroughly water tested prior to the commencement of any paving. Exposed trafficable membranes such as Microl allow access for inspection alteration or maintenance in the future and are the preferred option.
Microl is best applied to solid and continuous substrates laid to falls Suitable drainage should be allowed. Compressed timber board is not a suitable substrate for the application of membranes and should not be used. Entrapped moisture and air in the substrate may cause blisters in the membrane surface due to volume increase when exposed to hot weather conditions. Heavier than specified coats applied on hot days may also cause blistering.
Clean with water while wet & use paint stripper when cured.
