However, the substrate should only have <br />a matt damp surface when applying ASOCRET-FS. <br />Preparation of the substrate is necessary e.g. grit <br />blasting, shot blasting, high pressure jet washing <br />(500–2000 bar) if no other concrete restoration <br />measures were carried out. Cementitious surfaces must <br />be sound, open textured with a good key and be loadbearing, free from cement laitance, loose areas as well <br />as adhesion inhibiting substances (oil, grease, rubber <br />marks, paint residues or other contamination).</p> <p>Minimum concrete substrate age: 28 days <br />Medium surface tensile strength: min. 1.5 N/mm2 <br />Abrasion resistance required for concrete substrates: <br />min. 1.5 N/mm² <br />Product preparation: <br />Preparing the fine mortar: <br />• ASOCRET-FS <br />25 kg <br />• Water <br />approx. 5.0 – 5.25 litres <br />Material consumption (prepared mix): <br />Approx. 1.6 kg/m²/mm thickness <br />Approx. 1.0 l / mix = 2.0 kg <br />Place up to 80% of the water quantity given above into <br />a clean mixing bucket. <br />Slowly add the above quantity of ASOCRET-FS whilst <br />continuously mixing with suitable equipment (approx. <br />300 rpm). Thoroughly blend the material for approx. 3 <br />minutes to a lump free mortar. Then add the remaining <br />water and mix for a further 2 minutes. Allow to stand <br />for 2 minutes then briefly re-mix. When mixing large <br />quantities, use a forced paddle mixer. Only mix as</p> <p>1/3</p> <p>49/14</p> <p>much material as can be used within the pot life given <br />above. <br />Application tools: <br />Hand trowel, steel float, lath, rubbing sponge <br />Application by hand: <br />Apply ASOCRET-FS to the prepared matt damp <br />substrate to the desired thickness. Pores and cavities <br />should be trowelled over initially. After allowing the <br />appropriate waiting time, smoothen the surface. The <br />surface may not be post-treated with a wet brush or wet <br />trowel. It is possible to rub up after application using <br />a dry sponge to achieve a neat transition within the <br />repaired area. <br />Wet spray application: <br />When applying with wet spray techniques, it is <br />necessary to thoroughly dampen the surface to be <br />coated until matt damp. <br />Re-profiling with wet spray techniques is carried out after <br />mixing in a compulsory mixer with a suitable feed pump <br />using a 12 mm spray re-profiling gun or a 35/12 <br />mm MAWO nozzle. For an even spray pattern a high <br />output construction compressor (min. 4 m3 air / 4 - 5 <br />bar operating pressure) is a mandatory requirement. <br />Without compulsory mixer: <br />Pump system: High Comp Power <br />Pump unit: XP 120 <br />Water demand: approx. 160 – 180 l/hr <br />Nozzle: MAWO nozzle 35/12 mm or 12 mm <br />re-profiling spray gun <br />Max. Pipe length: 30 m <br />Control nozzle displacement: 0.5 – 1.0 m <br />PFT pump system: <br />Multi Mix compulsory mixer <br />Feed pump N2FU4000 / screw conveyor D8-1.5 <br />Reprofiling spray gun 12 mm <br />Max. Pipe length: 30 m <br />Control nozzle displacement: 0.5 – 1.0 m</p> <p>Inotec pump system: <br />Inomix compulsory mixer ZM80 Jet Mix <br />Inobeam F21 light / screw conveyor D8-1.5 <br />Reprofiling spray gun 12 mm <br />Max. Pipe length: 30 m <br />Control nozzle displacement: 0.5 – 1.0 m <br />Material application: <br />Through the addition of air at the spray nozzle, the <br />mortar is sprayed in a circular manner in order to <br />achieve a clean spray pattern. The first pass of the <br />spray head is to fill holes and cavities and to even out <br />irregularities in the substrate. The second spray pass is <br />to achieve the required thickness and to finish with a <br />suitable smoothing tool. <br />Post-treatment: <br />Following the application of ASOCRET-FS, it is <br />fundamentally necessary to protect the mortar surfaces <br />from drying out too quickly using suitable measures <br />Keep damp for at least 3–5 days using mist spray <br />nozzles or wet jute sacking as required also covered <br />with polythene sheets. The polythene sheets must be <br />fastened to the area treated, so that air exchange <br />cannot take place. If the area in question is exposed to <br />direct sunlight, draughts, large temperature fluctuations <br />and/or low humidity then after care treatment must be <br />intensified. If it is intended to apply a mineral-based <br />waterproof slurry, then this can be used as an alternative <br />after care treatment after approx. 24 hours. <br />Important advice: <br />• Prior to carrying out concrete repair works the <br />actual condition should be inspected by an expert <br />or Structural Engineer. The inspection report is to be <br />given to the applicator prior to commencement of <br />repair work. <br />• Protect surfaces not being treated with ASOCRET-FS. <br />• Cover with suitable sheeting to protect from rain. <br />• Building substrate and ambient temperatures below <br />+20 °C retard the set time. Building substrate and <br />ambient temperatures above +20 °C accelerate the <br />set time.</p> <p>2/3</p> <p>49/14</p> <p>•W <br /> hen preparing ASOCRET-FS only use mains or <br />drinking water. Material that has started to stiffen may <br />not be diluted with water or more powder added. <br />There is a risk of an inadequate bond. <br />•A <br /> pplications that are not clearly explained in <br />this technical data sheet may only be carried <br />out after consultation with and written confirmation <br />from the Technical Services Department of <br />SCHOMBURG GmbH & Co.
