C20/25 <br />• Screed quality: <br />min. EN 13813 CT-C25-F4 <br />• Age: <br />min. 28 days <br />• Tensile adhesion <br />strength: <br />1.5 N/mm2 <br />• Residual moisture: < 4% (carbide hygrometer <br />method)</p> <p>1/3</p> <p>20/17</p> <p>Product preparation: <br />Components A (resin) and B (hardener) are delivered <br />in a predetermined mixing ratio in a two compartment <br />container. Pull out the separating clamp to allow both <br />components to run together. Mix the bag contents by <br />kneading and tumbling. Ensure that the mix is homogenous <br />(free from striations); mixing time approx. 3 minutes. The <br />minimum temperature during mixing should be +15 °C. <br />Once mixed untwist the threaded closure on the top of the <br />bag and squeeze out the mixture.</p> <p>Consumption: <br />approx. 300 - 500 g/m2. <br />The mixed smoothing compound is then trowel applied <br />in a single operation. Immediately afterwards broadcast <br />the smoothing compound, whilst it is still wet, with fine <br />quartz sand of particle size 0.1 - 0.4 mm or 0.2 - 0.7 <br />mm. <br />Consumption of finished smoothing compound: <br />approx. 1,600 g/m2/mm.</p> <p>Methods of application / consumption: <br />1. Sealing cracks in screed and concrete using screed <br />clips: <br />Open up the crack or joint with a cutting disc along its <br />length to 1/2 to 2/3 the screed thickness. Cut approx. <br />10 cm long cuts across the crack at right angles approx. <br />every 30 cm. Thoroughly remove dust from the cut area <br />using an industrial vacuum cleaner. Pour the premixed <br />casting resin into the cut joints until visibly saturated. It is <br />possible that a second pour will be necessary. <br />Place the screed clips supplied in the crosscuts and wipe <br />off expelled resin from the surface. Then blind the wet <br />resin surface with quartz sand of particle size 0.2 <br />to 0.7 mm. <br />Once hardened vacuum away all non-bound, loose <br />sand. After 4 – 5 hours the hardened casting resin can <br />be abraded. For abrasion 60 grade grit paper is suitable. <br />Afterwards thoroughly de-dust the surface.</p> <p>3. Repair of small areas with extensive and deep <br />damage: <br />For repairing large damaged holes produce a mortar <br />using the binder ASODUR-K900 as follows: <br />Production of the epoxy mortar: <br />Thickness: <br />approx. 3 to 15 mm <br />ASODUR-K900: <br />1.0 part by weight <br />Quartz sand: 7.5 - 10.0 parts by weight, <br />particle size 0 - 1.5 mm Ø <br />Place the determined quantity of quartz sand into a <br />large mixing container. Subsequently add the pre-mixed <br />resin and hardener components. Ensure that the liquid <br />and solid constituents are evenly blended. <br />Firstly prime the substrate with ASODUR-K900. <br />Consumption: <br />approx. 300 - 500 g/m2. <br />Apply the mixed mortar onto the freshly primed surface <br />to a minimum thickness of 5mm, mechanically tamp <br />and smooth off. Immediately afterwards broadcast <br />the mortar, whilst it is still wet, with fine quartz sand of <br />particle size 0.1 - 0.4 mm or 0.2 - 0.7 mm. <br />Mortar consumption: approx. 2.0 kg/m2/mm.</p> <p>2. Levelling out irregularities: <br />For levelling irregularities produce a smoothing compound <br />with ASODUR-K900 as the binder as follows: <br />ASODUR-K900: 1.0 part by weight <br />Quartz sand: approx. 1.0 part by weight (particle <br />size 0.1 - 0.4 or 0.2 - 0.7 mm) <br />Note: Ensure that the liquid and solid components are <br />evenly blended. <br />Firstly prime the background with ASODUR-K900.</p> <p>4. Filling of voids <br />In order to fill voids, the area where pouring is to take <br />place needs to be made accessible by opening up <br />and/or drilling. After the preparatory measures have <br />been implemented thoroughly clean and remove dust. <br />Afterwards pour the mixed casting resin into the void <br />in stages. It is possible that a second pour will be <br />necessary. <br />Consumption: <br />approx. 1.10 kg per volume.</p> <p>2/3</p> <p>20/17</p> <p>Health & Safety: <br />Once cured, ASODUR-K900 is harmless. <br />The hardener (component B) is corrosive. <br />We draw your attention to current advice/brochures <br />“Epoxy resins and hardeners” distributed by <br />PlasticsEurope www.plasticseurope.org. <br />Further information: <br />BGR 190 – Regulations for the use of breathing <br />apparatus <br />BGR 192 – Regulations for the use of eye and face <br />protection <br />BGI 868 – Protective gloves for chemicals <br />Follow the advice on the packaging. <br />Important advice: <br />• Only fill screed crack and shrinkage control joints <br />once the screed has reached the accepted moisture <br />level and is ready to receive finishes. <br />• Higher temperatures shorten the pot life and curing <br />time. Lower temperatures increase the pot life and <br />curing time. Material consumption is also increased at <br />lower temperatures.</p> <p>• The bond between the individual coats can be <br />heavily impeded through the influence of dampness or <br />contamination between the applied coats. <br />• When longer waiting times occur between the <br />application of coats the surface must be well cleaned <br />and abraded, after which a completely new and even <br />application of the adhesive/casting resin should be <br />carried out. <br />• After application the resin must be protected from <br />damp (e.g. rain, melt water). Dampness produces a <br />white discolouration and/or stickiness on the surface <br />and can impede the cure. Discoloured and/or sticky <br />surfaces should be taken off e.g. by abrading and <br />renewed. <br />• Applications that are not clearly explained in this <br />technical data sheet may only be carried out after <br />consultation with and written confirmation from the <br />Technical Services Department of SCHOMBURG. <br />• Waste disposal key: <br />Liquid residues: EAK 08 01 11 paint and lacquer <br />waste that contains organic solvents or other <br />dangerous substances. <br />Hardened residues: EAK 17 02 03 plastics <br />Please observe a valid EU safety data sheet! <br />GISCODE: RE 1</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
