ASODUR-LE consists of a two-component, <br />solvent free, low viscosity epoxy resin (as binder) and a <br />special lightweight aggregate as the third component. <br />After installation ASODUR-LE has a weight per area of <br />only approx. 18 kg/m2 at 15 mm minimum thickness. In <br />the hardened state ASODUR-LE possesses high abrasion <br />resistance, heat insulating properties and impact sound <br />minimising properties when used with conventional impact <br />sound insulation.</p> <p>*) at +23 °C and 50% rel. humidity</p> <p>Consumption: <br /> approx. 1.18 kg/m2 <br /> <br />per mm thickness <br />Cleaning: <br />Clean tools immediately after use <br /> <br />with ASO-R001. <br />Packaging: <br />30 kg and 60 kg units <br />The packaging contents are composed of: <br />30 kg <br />ASODUR-LE (binder)</p> <p>Areas of application: <br />ASODUR-LE is used in the renovation of old buildings <br />• on wooden floors as a substrate for the installation of <br />ceramic tiled finishes in wet areas when in combination <br />with the necessary waterproofing measures. <br />• on old wooden floorboards as a substrate for ceramic <br />floor tiles, natural stone, floor coatings, parquet or <br />carpet. <br />• on cement-based substrates, on asphalt floors etc.</p> <p>Special lightweight aggregate</p> <p>60 kg</p> <p>5 kg</p> <p>10 kg</p> <p>2 × 12.5 kg</p> <p>4 × 12.5 kg</p> <p>Storage: Binder: 18 months when stored <br />frost-free, cool and dry in the original <br />unopened container, above +10 °C. <br />Protect from direct sunlight and cold. <br />Storage should be in compliance <br />with the regulations for storing <br />products dangerous to watercourses. <br />Observe EU safety data sheet.</p> <p>1/3</p> <p>06/20</p> <p>Method of application: <br />1. Priming: <br /> <br /> ASODUR-SG3-superfast (rapid setting primer for work <br /> in small areas) or ASODUR-SG3 (normal setting <br /> primer for work over large areas) is evenly applied <br /> to the substrate with a roller in a single application <br /> step, in order to improve the processability and <br /> adhesion capacity. <br /> Coverage: <br /> approx. 300 g/m² per application step. <br />2. The mixed lightweight screed is applied to the primed <br /> surface whilst still wet, and height-levelled with gauge <br /> rake. <br />3. Thoroughly compact the lightweight screed once <br /> applied and then smooth.</p> <p>Surface preparation: <br />Existing substrates must be load-bearing, dust free and dry. <br />Damaged wooden and floorboard substrates are to be <br />replaced and loose boards are to be secured (e.g. screws <br />etc.). Leave a gap of at least 5 mm against adjacent <br />building elements by placing the self-adhesive edge <br />isolating strip RD-SK50 before applying the lightweight <br />screed. <br />Product preparation: <br />Production of the lightweight epoxy resin screed <br />ASODUR-LE: <br />5 parts by weight special lightweight aggregate: 1 part <br />binder (ASODUR-LE). <br />Components A (resin) and B (hardener) are delivered <br />in a predetermined mixing ratio. Tip component B into <br />component A. Ensure that the hardener drains completely <br />from its container. Mixing of the components is to be <br />carried out with a suitable mixer at approx. 300 min-1 <br />(e.g. drill with paddle). It is important to also stir from <br />the sides and the bottom to ensure that the hardener is <br />evenly dispersed. Stir until the mix is homogenous (free <br />from striations). Mixing time approx. 5 minutes. The <br />material temperature during mixing should be +15 °C. <br />Place the determined weight of lightweight aggregate <br />into the forced paddle mixer (e.g. type: Zyklos or UEZ). <br />Subsequently add the previously homogenously mixed <br />resin and hardener components of the binder. Ensure that <br />the liquid and solid components are evenly mixed. When <br />preparing small quantities of lightweight screed (5 kg units <br />ASODUR-LE binder, 25 kg special lightweight aggregate) <br />place the special lightweight aggregate into a mixing <br />bucket (capacity 60 litres) and add the previously mixed <br />resin and hardener components. Subsequently blend the <br />special lightweight aggregate and binder with a suitable <br />stirrer at approx. 300 min-1 (e.g. drill with paddle). Ensure <br />that the liquid and solid components are evenly mixed. <br />Decant the material into a clean container and mix through <br />thoroughly once again.</p> <p>Important advice: <br />When ASODUR-LE is installed on impact sound <br />deadening insulation, the following minimum thicknesses <br />are necessary – irrespective of the compressibility of the <br />insulation used: <br />Compressibility of the impact sound <br />deadening insulation: <br />Min. layer thickness ASODUR-LE:</p> <p>max. 1 mm</p> <p>max. 3 mm</p> <p>25 mm</p> <p>30 mm</p> <p>Where ceramic tiles are to be installed, follow <br />DIN 18560-2! <br />• If ASODUR-LE is used as a thin load distribution layer on <br />LEWIS dovetail sheeting, ensure that during installation <br />the deflection of the LEWIS dovetail sheeting is avoided <br />by using suitable load distribution such as e.g. shuttering <br />boards. Make sure the lightweight screed is optimally <br />compacted. <br />• When the screed is bonded at 15 mm, the tile size <br />should not be greater than 40 × 40 cm. Larger formats <br />would require installation to DIN 18560 part 2 <br />i.e. a separating layer and a thickness of 25 mm <br />ASODUR-LE.</p> <p>2/3</p> <p>06/20</p> <p>• The indicated consumption quantities are calculated <br />values without additions for surface roughness and <br />absorbency, level compensation, and residual material <br />in the container. We recommend a calculated safety <br />addition of 10% on top of the calculated consumption <br />quantities. <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 />• Cured product residues are to be disposed of under <br />waste disposal classification AVV 150106. <br />GISCODE: RE 1</p> <p>• Ensure the installation site is ventilated and avoid direct <br />sunlight. <br />• Do not add any additives to the screed. <br />• Higher temperatures shorten the application time. Lower <br />temperatures increase the application and hardening <br />times. The rate at which material is consumed also <br />increases at lower temperatures. <br />• The bonding between the individual layers can be <br />strongly disrupted between the individual application <br />steps due to the effects of dampness and contamination. <br />Application work requires a substrate temperature of <br />min. 3 °C above the dew point temperature. <br />• If longer waiting times arise between the individual <br />application steps or surfaces that have already been <br />treated with liquid resin are coated again after an <br />extended period of time, the old surface must be <br />well cleaned and thoroughly ground. Then perform a <br />complete pore-free new application. <br />• After they have been applied, artificial resin systems <br />must be protected against dampness (e.g. rainwater, <br />condensation water) for approx. 4–6 hours. Moisture <br />causes a white colour and/or stickiness on the surface <br />and can cause problems during curing. Discoloured <br />and/or sticky surfaces must be removed and reworked, <br />e.g. through grinding or shot blasting.</p> <p>Information about the emission level of volatile compounds in indoor <br />air, which pose a health risk by inhalation, on a scale from class A+ <br />(very low emissions) to C (high emissions).</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
