Durafloor Leveltop Rapid TDS - Parchem

Technical Data SheetDurafloor Leveltop RapidFloor underlay, self smoothing, levelling mortar for carpet / tiles / vinyl(0-50 mm thickness)USESDurafloor Leveltop Rapid is designed as a heavy duty floorrepair compound which provides a very smooth surfaceallowing the smooth installation of carpet, ceramic tilessheet rubber, sheet vinyl and vinyl tiles.Durafloor Leveltop Rapid may, depending on the end use ofthe floor, be used in conjunction with epoxy resin basedsystems such as Durafloor SL.Durafloor Leveltop Rapid can be used in residential,commercial and any applications where a fast settinginternal floor repair of high strength and compatibility withother floor coverings are required.ADVANTAGES• Can be applied directly onto prepared concrete floors,eliminates traditional sand cement screeds• Dimensionally stable, will not curl or crack• Excellent adhesion to prepared substrates• Rapid hardening and curing allows speedy access forfoot traffic and overlaying with carpet, vinyl etc.• One pack product eliminating on-site batching andensures consistency of mixed product• Produces a very smooth surface essential for laying thinsheet coverings such as vinyl etc.• Can be ‘feather edged’DESCRIPTIONDurafloor Leveltop Rapid consists of a blend of selectedcements and aggregates modified with polymers and flowagents. It is used in conjunction with Durafloor Level Primeto rapidly repair / patch internal concrete substrates.Durafloor Leveltop Rapid is supplied as a grey powderwhich requires only the addition of water to produce asmooth trowellable material.TECHNICAL SUPPORTParchem offers a comprehensive range of highperformance, high quality flooring, jointing and repairproducts for both new and existing floor surfaces. Inaddition, Parchem offers a technical support package tospecifiers, end-users and contractors, as well as on-sitetechnical assistance.DESIGN CRITERIADurafloor Leveltop Rapid is designed for applicationthicknesses of up to 50 mm. Thicker application is possiblehowever your local Parchem sales branch should beconsulted for specific advice in this situation. DurafloorLeveltop Rapid can be applied to clean, sound and wellprepared concrete substrates which are free from loosematerial, oil, grease, paint etc. and have a minimumcompressive strength of 20 MPa.The relative humidity of the concrete substrate must not begreater than 80% at the time of installation.New concrete should be at least 14 days old.PROPERTIESThe values given below are average figures based on 4.5litres of water added per 20 kg bag of Durafloor LeveltopRapid.

Durafloor Leveltop RapidMAINTENANCEIf damage has occurred to Durafloor Leveltop Rapid prior tothe installation of the final floor finish, repair of that areacan be achieved by removing any loose material, prime therepair area with Durafloor Level Prime, allow to dry andrepair with Durafloor Leveltop Rapid.APPLICATION INSTRUCTIONSPREPARATIONThe substrate should be clean, sound and free from loosematerial and contamination such as plaster, oil, paint andgrease.New concrete should be at least 14 days old.Excess laitance should be removed by light scabbling orcaptive shot blasting followed by vacuuming to removedust debris.PRIMINGThe object of priming is to seal the substrate to prevent airrelease from the subfloor rising and forming bubbles andpinholes on the surface of the Durafloor Leveltop Rapid.Extremely porous substrates may require two priming/sealing coats. If two primer coats are required, the secondcoat must be allowed to dry before applying the DurafloorLeveltop Rapid.Prime the surface with Durafloor Level Prime Concentratebroken down with 4 parts water to 1 part Durafloor LevelPrime (by volume) and allow to dry.For application where water vapour, seepage or moistureare of concern, pre-treatment and treating with Emer-ProofAqua Barrier** is recommended.**Refer to separate data sheet.APPLICATION OF DURAFLOOR LEVELTOP RAPID OVEREMER-PROOF AQUA BARRIERApply the first two (2) coats of Aqua Barrier as per the TDSand allow to cure. When using Emer-Proof Aqua Barrierunder Durafloor Leveltop Rapid, it is essential that a thirdcoat of Emer-Proof Aqua Barrier is applied to act as abonding coat. The bonding coat of Emer-Proof Aqua Barrieris to be applied at 5m 2 /L and Durafloor Leveltop Rapid mustbe applied whilst the bonding coat is still tacky. If thebonding coat has been allowed to cure to a tack free state, afurther coat must be applied prior to application ofDurafloor Leveltop Rapid.MIXINGPour required amount of water into suitable mixingcontainer. Slowly add Durafloor Leveltop Rapid whilstmixing with a suitable mixer such as a Festo Mortar Mixer.After all powder is added continue to mix for 2 - 3 minutesto ensure even consistency throughout.During use, avoid inhalation of dust and contact with skinand eyes. Wear suitable protective clothing, gloves, eyeprotection and respiratory protective equipment.- Each 20 kg bag of Durafloor Leveltop Rapid requiresthe addition of 4.5 litres of clean, cool water to producea trowellable consistency.INSTALLATIONApplication procedure is as follows:- Thoroughly prepare the floor surface.- Reprime the surface if necessary, and allow to dry.- Pour the mixed material on to the dry primed surfaceand spread with a trowel. Best results are achievedwhen the levelling is a continuous process by workingthe material into the primed surface firmly.- Apply Durafloor Leveltop Rapid by trowelling firmlyensuring the mortor ‘wets’ the surface. Allow 10minutes (approx.) before trimming the excess andsmoothing off. As soon as the mortar has hardened,levelling (if applicable) can occur.Note: if the mix stiffens it should be discarded, do notattempt to re-mix with water.- As soon as the Durafloor Leveltop Rapid has hardened,the surface of the floor can be overlayed with any of theParchem range of cementitious levelling compounds.CLEANINGDurafloor Leveltop Rapid and Durafloor Level Prime shouldbe removed from tools and equipment with clean waterimmediately after use. Hardened material can only beremoved mechanically.LIMITATIONSDurafloor Leveltop Rapid has a 28 day compressivestrength of 25 MPa, it is designed as an underlay materialand will provide the advertised properties only when wateraddition is not exceeded.Durafloor Leveltop Rapid must not be used in areas whereback water pressure is likely. Refer to Parchem forapplication where rising damp or hydrostatic waterpressure is likely.To prevent rapid drying protect from direct sunlight and/ordrying winds during application and the final curing period.If the surface onto which Durafloor Leveltop Rapid isapplied moves or cracks, reflective cracking may occur.2
