Alternatively ASOCRET-IM can also <br />be used to form coved fillets. <br />Technical Data: <br />Basis: sand/cement, inorganic <br />Colour: grey <br />Loose density: <br />1.4 kg/dm3 <br />Water demand: <br />3.75 – 4.25 litres <br /> <br />per 25 kg bag <br />Mixing time: <br />3 minutes (drill mixer at <br /> <br />300 – 700 rpm) <br />Pot life: <br />approx. 30 minutes <br /> <br />(+23° C / 50% RH) <br />Application/ <br />Surface temperature: <br />+5° C to +30° C. <br /> <br />Lower temperatures shorten, <br /> <br />higher temperatures lengthen <br /> the setting time <br />Cleaning: Cleaning of equipment whilst <br />still fresh with water. <br />Remove dried-on material with <br />ASO-R005 cleaner. <br />Compressive strength: approx. 20 N/mm2 <br /> (after 28 days) <br />Storage: dry, 12 months in original <br />unopened packaging. <br />Use opened packaging <br />immediately.</p> <p>Packaging: <br />25 kg bag <br />Material comsumption: <br />• U shaped cracks cut out to 20 x 25 mm: <br />approx. 1.3 kg/m. <br />• Coved fillets approx. 38 mm haunch height: <br />approx. 1.3 kg/m. <br />Surface preparation: <br />Use ASOCRET-IM exclusively on concrete and <br />reinforced concrete substrates that are clean, sound, <br />load-bearing, open-pored and porous. Abrade smooth <br />and dense substrates. Contaminated surfaces should <br />be appropriately prepared by a suitable method (e.g. <br />sand-blasting, high pressure jetting, shot-blasting or grit <br />blasting). Dampen substrates well with water but avoid <br />the formation of puddles. Plug water leaks with <br />FIX-10-S or FIX 20-T. Chisel out static cracks to a <br />minimum width of 20 mm and a minimum depth of <br />25 mm. Before filling, pre-coat the sides with <br />AQUAFIN-IC and seal up to the surface with <br />ASOCRET-IM whilst the bond coat is still wet. Repair <br />dynamic cracks by injecting AQUAFIN-P1/P4. Form <br />cement-based coved fillets at the wall/base slab <br />junction as well as at corners and edges. Apply a <br />slurry bonding coat of AQUAFIN-IC to the substrate <br />when forming coved fillets, with an approx. 4 cm side <br />length and apply the ASOCRET-IM whilst it is still wet. <br />After approx. 1 - 3 hours overcoat the ASOCRET-IM <br />with AQUAFIN-IC. If this is not possible then roughen <br />up the surface again once fully hardened and coat with <br />AQUAFIN-IC. <br />Product preparation: <br />Pour 3.75 – 4.25 litres of clean water into a mixing <br />bucket and thoroughly stir in as much dry powder <br />(drill with paddle 300 – 700 rpm) until a lump-free <br />homogenous trowellable paste is achieved. Apply the <br />mortar with a trowel or float. Only mix sufficient material <br />that can be used within 30 minutes. Application to larger</p> <p>1/2</p> <p>19/17</p> <p>areas can be carried out up to max. 10 mm thickness in <br />one layer. <br />Important advice: <br />• A sound substrate is a pre-requisite for a durable <br />bond between substrate and coating system. Weakly <br />bonded substances or those that interfere with <br />bonding must be completely removed. High pressure <br />jetting (> 400 bar) with rotating spray head, very high <br />pressure jetting (up to 2.000 bar) and blasting with <br />solid blasting abrasives are suitable methods. The final <br />cleaning method must be a water jet method. <br />• Protect areas not be treated from the effects of <br />ASOCRET-IM. <br />• Do not apply to frozen substrates. <br />• ASOCRET-IM may not be used as an additive for <br />concrete or renders i.e. it may not be mixed with <br />such products. <br />• The reaction between ASOCRET-IM and free lime <br />in the concrete can lead to small incidences of <br />efflorescence. This is not a defect and can be <br />brushed away. <br />• Do not apply to dry substrates. <br />• Use suitable protective measures to prevent <br />ASOCRET-IM from dewatering too quickly. <br />• Varying final colour depends on the varying moisture <br />content of the concrete. <br />Please observe a valid EC safety data sheet. <br />GISCODE: ZP1</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
