Kerakoll Levelflex External further informationCoverage: approx 2.50Kg/m2 per mm of thicknessApplication AreasIntended use: Self-levelling correction of irregular and uneven substrates, in external and submerged installations, such as external patios and terraces, swimming pools and water features. Rapid setting and drying and shrinkage compensated. Can be applied from 2 mm to 50 mm.Compatible adhesives: – gel adhesives, mineral adhesives, single- and two-component organic mineral adhesives – reactive-epoxy and polyurethane, single and two-component cement-based adhesives, dispersed in water or solvent solutionsCovering materials: – ceramic, porcelain, natural stone and mosaic tiles – resins for industrial floors from the Kerakoll Factory range Substrates: – mineral screeds made with Keracem Eco as binder or pre-mixed product – cement-based screeds – prefabricated concrete or fresh concrete castingsExternal floors in domestic and commercial applications.~* Kerakoll Levelflex External from us comes with Free Upgraded Express Next Working Day Delivery *~Kerakoll Levelflex External InstructionsPreparation of substratesThe substrate must comply with current British standards and industry regulations. In general, substrates must be free of dust, oil and grease, free from any moisture rising, with no loose, flaky or imperfectly anchored parts such as residues of cement, lime, paint coatings and adhesives, which must be completely removed. The substrate must be stable, non-deformable, without cracks and have already completed the curing period of hygrometric shrinkage.In particular, substrates must be treated with a suitable primer as shown in the table below:PreparationPour 3.5 – 4.2 l of clean water into a clean container; then pour in a bag of Levelflex External, while shaking. Mix with a mechanical mixer until a smooth, lump-free and self- evelling mixture is achieved. Larger quantities of Kerakoll Levelflex External may be prepared in suitable mixers. After the first mixing, it is advisable to leave the mixture to rest for approx. 2 minutes and then mix again briefly. Levelflex External features a high degree of self-levelling capacity. Adding extra water does not improve the workability of the product, and may cause shrinkage in the plastic phase of drying and result in less effective final performance with a reduction in surface hardness, compressive strength and adhesion to the substrateInstructions for useApplication Levelflex External is generally applied with a flooring trowel. Application with a mechanical pump enables homogeneous correcting in a very short time on large continuous surfaces. The use of a spike roller or aeration roller can be used to further improve the surface finish of Kerakoll Levelflex External by removing entrapped air from the mixture.Cleaning Residual traces of Levelflex External can be removed from tools using water before the product hardens.NotesJoints: perimeter expansion must be allow for in the application of self levelling compounds. Perimiter expansion edging strip must be installed along the whole perimeter of the room, on the walls and on any other vertical elements protruding from the supporting layer. Large and continuous surface areas need to be fractionised as soon as they can withstand foot traffic so to create areas < 100 m2 with 10 m maximum individual size. All movement or expansion joints located in the substrate must be respected.Overlaying: if an additional application of Levelflex External is required once the initial application has been completed, the first installation layer must first be hardened and ready to accept foot traffic and additional application, this is generally after 3 hours.The initial layer of Kerakoll Levelflex External must be primed with a neat coat of Kerakoll Primer A Eco prior to subsequent applications.Kerakoll Levelflex External technical dataAppearancegrey pre-mixedApparent volumetric mass≈ 1.18 kg/dm3Mineralogical nature of inert materialsilicate - crystalline carbonateGrading0 – 600 μmShelf life≈ 12 months from the date of production in the original, unopened packaging; protect from humidityMixing water≈ 3.8 - 4.2 l / 1 bag 20 kgSpecific weight of the mixture≈ 2.03 kg/dm3 (UNI 7121)Self levelling time≈ 30 min.End setting time≈ 3 hrsTemperature range for applicationfrom 5 °C to 35 °CMaximum thicknessbetween 2 and 50 mmFoot traffic≈ 3 hrsWaiting time before laying:- ceramic, porcelain, natural stone and mosaic tiles≈ 3 hrsCoverage≈ 2.50 kg/m2 per mm of thicknessKerakoll Levelflex External performancesVOC Indoor Air Quality (IAQ) - Volatile organic compound emissionsConformityEC 1 Plus GEV-EmicodeEC 1 Plus GEV-EmicodeHIGH-TECHResistance to:- compressive after 24 h= 8 N/mm2EN 13892-2- compressive after 7 days= 15 N/mm2EN 13892-2- compressive strength after 28 days= 25 N/mm2EN 13892-2- flexural after 28 days= 6 N/mm2EN 13892-2Classification/ConformityCT-C25-F6EN 13813NBProduct for professional use abide by any British standards and industry regulations do not use Keraflex Levelflex External to correct substrate irregularities greater than 50 mm in a single coat do not add other binders, additives or pigments to the mixture low temperatures and high relative humidity lengthen the drying time and can saturate the environment; this may have a negative effect on the quality of the surface of the self-levelling product an excessive quantity of water will reduce strength and the drying time respect any movement or expansion joints present in the substrate if necessary, ask for the safety data sheet for any other issues, contact the Kerakoll Worldwide Global Service.
