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 a functioing DPM within the subfloor. If no DPM is present, a surface epoxy DPM must be applied before installing resilient floor coverings. Kerakoll Proflow Smooth can be used to pre-smooth the floor at 95% RH prior to installing a surface epoxy DPM. In particular, substrates must be treated with a suitable primer as shown in the table:Kerakoll Proflow Smooth substratesSubstratePrimersDilution with waterCement-based screedsActive Prime FixDilutedCalcium sulphate- based screedsActive Prime FixNeatConcretesActive Prime FixDilutedCeramic floors ceramic tilesActive Prime FixNeatFlooring grade plywoodActive Prime FixDilutedGypsum fibre or fibre-cement panelsActive Prime FixDilutedMetal substratesActive Prime FixNeatEpoxy DPMActive Prime FixNeatFlooring grade asphalt/bitumenActive Prime FixNeatPreparation:Pour the pre-measured 5 l bottle of Kerakoll Proflow Smooth liquid into a clean container; then pour in a bag of Kerakoll Proflow Smooth, while shaking. Mix with a mechanical mixer until a smooth, lump- free and smoothing mixture is achieved. Larger quantities of Proflow Smooth 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. Proflow Smooth features a high degree of self-smoothing 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, surface finish, compressive strength and adhesion to the substrate.ApplicationKerakoll Proflow Smooth is generally applied with a flooring trowel, cam rake or pin level. The use of an aeration tool or spike roller can be used but is not required to further improve the surface finish of Proflow Smooth, but will work to remove entrapped air from the mixture. If an additional application of Proflow Smooth 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 3.5 hours.The initial layer of Kerakoll Proflow Smooth must be primed with a neat coat of Kerakoll Active Prime Fix 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 smoothing compound during the setting phase.CleaningResidual traces of Kerakoll Proflow Smooth can be removed from tools using water before the product hardens.NBJoints: perimeter expansion must be allowed for in the application of self smoothing 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 substrate/subfloor. All movement or expansion joints located in the substrate must be honoured.Kerakoll Proflow Smooth technical dataAppearancegrey pre-mixedApparent volumetric mass≈ 1.19 g/dm3Mineralogical nature of inert materialsilicate - crystalline carbonateGrading0-600 μmShelf life≈ 12 months from production in the original sealed packaging, protect from humidityMixing water≈ 5.0 l bottle / 1 bag 20 kgSpecific weight of the mixture≈ 2.03 g/dm3Self levelling time≈ 30 min.Temperature range for applicationfrom 5 °C to 30 °CMaximum thicknessfrom 3 to 12 mmFoot traffic≈ 90 min.Waiting time before laying:LVT, vinyl, sheet vinyl, safety flooring and all other resilient floor coverings≈ 3.5 hrs- resins and paint≈ 12 hrsCoverage≈ 1.481 kg/m2 per mm of thicknessKerakoll Proflow Smooth performance – High-TechResistance to:- compressive after 24 h≥ 11 N/mm2EN 13892-2- compressive after 7 days≥ 15 N/mm2EN 13892-2- compressive strength after 28 days≥ 16 N/mm2EN 13892-2- flexural after 28 days≥ 7 N/mm2EN 13892-2Classification/conformityCT–C16–F6EN 13813NB2Product for professional useabide by any British standards and industry regulationsdo not use Proflow Smooth to correct substrate irregularities greater than 12 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 product strength and increase the drying timebefore laying hardwood floors, check the residual moisture content is within the accepted parameters given by the flooring manufacturer honour 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 Categories: All Products, Floor Levelling & Smoothing Compounds Pallet Deals, Smoothing Compounds - Pallet Deals
