The joint width to depth ratio is important at the timeof the application of the sealant (guide value of +10°C).For a temperature differential of +40°C:Joint distance 2 m 4 m 6 m 8 mMin. joint width 10 mm 15 mm 20 mm 30 mmThickness of sealant 10 mm 12 mm 15 mm 25 mmFor exterior areas (max. temperature differential of +80°C):Joint distance 2 m 4 mMin. joint width 15 mm 30 mmThickness of sealant 12 mm 15 mm2 2/5Sikaflex® Floor

All joints must be properly designed and dimensioned by the specifier and the maincontractor in accordance with the relevant standards, because changes are notusually feasible after construction. The basis for calculation of the necessary jointwidth, are the technical values of the joint sealant and the adjacent buildingmaterials, plus the exposure of the building, its method of construction and itsdimensions.Joint width 10 mm 15 mm 20 mm 25 mm 30 mmJoint depth 10 mm 12 - 15 mm 17 mm 20 mm 25 mmJoint length / 600 ml ~ 6 m ~ 2.5 - 3.0 m ~ 1.8 m ~ 1.2 m ~ 0.8 mBacking: Use only closed cell, polyethylene foam backing rods.Substrate QualitySubstrate Preparation /PrimingThe flush joint design rules out triphazards and dirt traps.The recessed joint design protects thesealant against mechanical loads.Clean and dry, homogeneous, free from oils and grease, dust and loose or friableparticles. Cement laitance must be removed.Non porous substrates:E.g. metals, powder coatings etc. have to be cleaned with a fine abrasive pad andSikaCleaner-205 by using a clean towel / cloth.After a flash off time of at least 15 min, apply SikaPrimer-3 N by using a brush.Before sealing allow a flash off time of at least 30 min. (max. 8 hrs.).For PVC use SikaPrimer-215.Before sealing allow a flash off time of at least 30 min. (max. 8 hrs.).Porous substrates:E.g. concrete, aerated concrete and cementitious renders, mortars, brick, etc. haveto be primed with SikaPrimer-3 N by using a brush.Before sealing allow a flash off time of at least 30 min. (max. 8 hrs.).Important note:Primers are only adhesion promoters. They neither substitute for the correctcleaning of the surface nor improve their strength significantly.Primers improve long term performance of a sealed joint.For further information refer to the Sika ® Primer table.ApplicationConditions /LimitationsSubstrate TemperatureAmbient TemperatureSubstrate MoistureContent+5°C min. / +40°C max.+5°C min. / +40°C max.Dry3 3/5Sikaflex® Floor

ApplicationInstructionsApplication Method /ToolsCleaning of ToolsNotes on Application /LimitationsSikaflex® Floor is supplied ready to use.After suitable joint and substrate preparation, insert Backing Rod to required depthand apply primer if necessary. Insert cartridge into sealant gun and firmly extrudeSikaflex® Floor into joint making sure that it is full contact with the side of the joint.Fill the joint, avoiding air entrapment. Sikaflex® Floor must be tooled firmly againstjoint sides to ensure good adhesion.Masking tape must be used where sharp exact joint lines or exceptionally neat linesare required. Remove the tape whilst the sealant is still soft. Sleek joint withsmoothing liquid for a perfect sealant surface.Clean all tools and application equipment with Sika Remover 208 / Thinner Cimmediately after use. Hardened / cured material can only be removedmechanically.Elastic sealants may not be over painted.Compatible coatings may cover the joint sides to max. 1 mm.The compatibility must be tested according to DIN 52 452-2.Colour deviations may occur due to exposure to chemicals, high temperatures, UVradiation(especially with colour shade white). However a change in colour will notadversely influence the technical performance or the durability of the product.Before using on natural stone contact our Technical Service.Do not use Sikaflex® Floor as a glass sealer, on bituminous substrates, naturalrubber, EPDM rubber or on building materials which might bleed oils, plasticisers orsolvents which could attack the sealant.Do not use Sikaflex® Floor to seal swimming pools.Do not mix with or expose uncured Sikaflex® Floor to substances that mayreact with isocyanates, especially alcohols which are often componentswithin e.g. thinners, solvents, cleaning agents and formwork releasingcompounds. Such contact could interfere or prevent the cross linking curingreaction of the material.4 4/5Sikaflex® Floor
