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, 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:Kerakoll Levelflex Gel substratesSubstratePrimersDilution with waterCement-based screedsPrimer A EcoDilutedCalcium sulphate- based screedsPrimer A EcoUndilutedConcretesPrimer A EcoDilutedCeramic floors ceramic tilesKeragrip EcoUndilutedFlooring grade plywoodPrimer A EcoDilutedGypsum fibre or fibre-cement panelsPrimer A EcoDilutedMetal substratesKeragrip EcoUndilutedPreparation Pour 4.5 – 5.2 l of clean water into a clean container; then pour in a bag of Levelflex Gel, while shaking. Mix with a mechanical mixer until a smooth, lump-free and self-levelling mixture is achieved. Larger quantities of Kerakoll Levelflex Gel 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. Kerakoll Levelflex Gel features a high degree of self-levelling capacity. Adding extra water does not improve its workability, 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 substrate.Application Levelflex Gel is generally applied with a flooring trowel. Application with mechanical pumps allows the installer to very quickly achieve a smooth high-thickness finish for large areas. The use of an aeration or spike roller can be used but is not required to further improve the surface finish of Levelflex Gel, but will work to remove entrapped air from the mixture. If an additional application of Levelflex Gel 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 90 minutes. The initial layer of Levelflex Gel must be primed with a neat coat of Kerakoll Primer A Eco prior to subsequent applications. In the case of low temperatures and high humidity it is advisable to keep the environment ventilated during application and during the hours immediately following application, in order to avoid the formation of condensation on the surface of the self-levelling gel during the setting phase.Cleaning Residual traces of Kerakoll Levelflex Gel can be removed from tools using water before the product hardens.Notes:Joints: perimeter expansion must be allow for in the application of self levelling compounds. Perimeter 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 broken into bays 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.Hardwood floors: for subsequent laying of hardwood floors, create a smooth finish with thickness ≥ 3 mm.Moisture-sensitive coverings: when laying moisture-sensitive coverings the residual moisture of Kerakoll Levelflex Gel must be checked on site in accordance with current regulations.Kerakoll Levelflex Gel technical dataAppearancegrey pre-mixedApparent volumetric mass≈ 1.17 g/dm3Mineralogical nature of inert materialsilicate - crystalline carbonateGrading0-600 μmShelf life≈ 12 months from production in the original sealed packaging, protect from humidityMixing water≈ 4.5 - 5.2 l / 1 bag 20 kgSpecific weight of the mixture≈ 2.01 g/dm3Self levelling time≈ 30 min.End setting time≈ 90 min.Temperature range for applicationfrom 5 °C to 35 °CMaximum thicknessfrom 2 to 100 mmFoot traffic≈ 90 min.Waiting time before laying:- ceramic, porcelain, natural stone and mosaic tiles≈ 90 min.- resins≈ 12 hrsCoverage≈ 1.525 kg/m2 per mm of thicknessKerakoll Levelflex Gel performanceVOC Indoor Air Quality (IAQ) - Volatile organic compound emissionsConformityEC 1 plus GEV-EmicodeGEV certified 17676/11.01.02HIGH-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≥ 7 N/mm2EN 13892-2- böhme wear after 28 days 22 cm3 / 50 cm2EN 13892-3Classification/ConformityCT–C25–F7EN 13813LimitationsProduct for professional useabide by any British standards and industry regulationsdo not use Levelflex Gel to correct substrate irregularities greater than 100 mmdo not add other binders, additives or pigments to the mixturelow temperatures and high relative humidity lengthen drying times and may saturate the environment with negative consequences on the surface consistency of the self-levelling gelan excessive quantity of water will reduce strength and the drying timebefore laying hardwood floors and resilient materials, check residual moisture with a hygrometerrespect any movement or expansion joints present in the substrateif necessary, ask for the safety data sheetfor unstable wooden types, particular substrates and for any other issues, contact the Kerakoll Worldwide Global Service 01772 456 831 – [email protected] Categories: All Products, Floor Levelling & Smoothing Compounds Pallet Deals, Floor Levelling Compounds - Pallet Deals
