They are provided as a guide to help ensurethe correct procedures are followed.• It is recommended that the installation of BostikUltraseal membranes should be carried out byprofessional applicators of waterproofing membranes.Installation shall be strictly in accordance with themanufacturer’s written instructions.• Bostik Technical Division must approve any modificationor variances with these specifications in writing.• When ever appropriate, the application of UltrasealMembranes must comply with AS3740-2004‘Waterproofing of Internal Wet Areas in residentialbuildings’

PREPARATION• Read precautions prior to applying any product from theUltraseal Membrane range.• Commencement of membrane installation shall be takenas acceptance of the substrate suitability andpreparation by the applicator.• All surfaces must be clean, dry and free of voids, curingcompounds, projections, loose materials, oils, grease,sealers and determined to be structurally sound beforethe application of Bostik Ultraseal.• New concrete must have cured for 28 days, mortar bedsand screeds 7 days.• Bostik Moisture Seal vapour barrier should be used toseal concrete slabs containing high moisture content(over 15%) prior to any membrane application.• Particularly rough surfaces should be filled using arecommended Bostik floor-leveling compound makingsure to follow instructions for preparation, applicationand curing time.• Ultraseal Membranes should not be applied in anyapplication until all preparation steps have beencompleted.• On completion of membrane placement, a lightbroadcast of medium to fine grade river sand couldbe thrown onto the still wet Ultrasealto enhance grout or tile adhesive adhesion.• Ultraseal should not be used in chlorinated water suchPRIMING• Prior to any application of Ultraseal it is recommendedthat a small amount of the selected membrane beapplied on the substrate surface and allowed to cure totest adhesion.• Bostik Ultraseal polyurethane membranes do notgenerally require priming except in applications wherethe membrane is to be applied to a substrate that hasbeen treated with coatings or sealers or is of particularlyunusual surface characteristics. Consult BostikTechnical Division for assistance if such circumstancesexist.• Bostik Guardcote, applied in accordance with theTechnical Data Sheet, must be used as a primer forUltraseal LV on porous surfaces to ensure sealing ofthe substrate to eliminate possible pin holing.MOIST OR DAMP SURFACES• New concrete must be cured for 28 days.• Bostik Ultraseal should not be applied to surfaces,determined by moisture meter, which have moisturecontents higher than 15%. Applications to thesesurfaces can result in adhesion failure or bubbling withsubsequent pin holing of the surface of the membrane.• Bostik Ultraseal Membranes are not vapourbarriers nor designed to stop a hydrostatic head of waterpressure. If substrate moisture is evident Bostik MoistureSeal (a vapour barrier) must be applied and allowed tofully cure before the introduction of any UltrasealMembranes (refer Technical Data Sheet forMoisture Seal application).INTERNAL WET AREAS –SEALING CORNERS & WASTE OUTLETS• Bostik Ultraseal Fillet & Seal polyurethane basedsealants are to be used in these applications.• Ensure falls required in the screed to shower recessbase, pipe outlets, angles and drainage are installedcorrectly.• All corners and substrate gaps around taps, showeroutlets, waste outlets, pipes, drains, flashings andnail/screw holes must be sealed using Ultraseal Fillet& Seal sealant.• Apply a 10mm bead of sealant by caulking gun directlyinto all wall/floor, hob/floor, hob/wall and wall/wallcorners to intending tile height.• Sealant should be spatula tooled smooth aroundfittings and pressed into corners creating an 8 –10mmtriangular fillet.• Allow sealant to tack off (approximately 45 minutes).• Apply primers (if required), after sealant tack off, to allareas intended for Ultraseal application.EXTERNAL DECK PREPARATION• If the balcony or deck areas to be coated are subject toservice or other building penetrations, it isrecommended, if possible, to install a flanged metalup-stand around the penetration.• Prime metal up-stand with Bostik 5077 primer and sealoff the perimeter of the penetration with a 10mm beadof Bostik Ultraseal Fillet & Seal sealant.CRACKS & NARROW JOINT SEALING• If cracks or narrow joints are evident in the floor area orwalls they need to be “chased out” and cleaned byspatula and stiff brush removing all residue.• After cleaning, fill all cracks and joints up to 3mm widewith a broad spatula application of Bostik Ultraseal Fillet& Seal. Cracks and joints greater than 3mm must befilled as detailed then bridge joint by spreading BostikUltraseal Fillet & Seal, minimum 2mm in depth, 35mmon either side and over the joint. Allow Ultraseal Fillet &Seal to reach initial set (approx. 45 minutes) beforereturning to apply the selected Ultraseal Membrane tothe area to be waterproofed.APPLICATION OF THE MEMBRANESULTRASEAL TROWEL & R GRADES• A minimum cured dry film thickness of 1mm must bemaintained with all Ultraseal grades to achieve awaterproof membrane. To ensure this cover isachieved it is recommended a wet film thickness of1.3mm (0.75m²/litre) be applied.WALLS• The wall/wall and wall/floor corner applicationinstructions for Ultraseal are applicable in all wet areaapplications.• From the intending tile height, apply Ultraseal by gun,small spatula or brush down all vertical corners thathave been previously sealed with Ultraseal Fillet &Seal.• With a brush (Ultraseal R), flat or corner trowel(optional method of smoothing material in corners)spread the Ultraseal evenly down the corners and out200mm onto adjacent walls. Ultimate shower recesscover would be to completely coat the whole wallareas with Bostik Ultraseal up to the intending tileheight.SHOWER BASE OR INTERNAL FLOORS• Continue across the wall to floor corners spreading200ml width onto both wall and abutting floor area.Smooth off the applied Ultraseal with a paintbrush.• For shower recesses repeat the same procedure overthe complete shower base working out and over thehob if fitted. Ultraseal must be dressed down the wasteat least 50mm.• This should now see Ultraseal evenly spread up allcorners to the intending tile heights and out 200mmeach side.• Check for pin holing, recoat pin holing if evident asnecessary to ensure membrane integrity.

ULTRASEAL R & LV GRADEEXTERNAL DECK APPLICATIONSAfter all preparation steps have been completed and anyprimers, if applied are dry, then;• Apply Ultraseal into wastes, drains or onto puddleflanges. Ultraseal must be dressed down into the wasteat least 50mm.• Apply an initial coat of Ultraseal either side of allwall/floor junctions and sheet flooring joints. Extend thecoating at least 200mm either side of the joins.• Once initial coat is completed and “tacked off”, pour aliberal amount of selected membrane onto the substrateand spread by use of a nap roller. Move the materialaround and cross roll to ensure an even flow and cover.• If the product looks transparent apply more material.This is an inbuilt safety feature of Ultraseal R and LV.• Ultraseal LV will slump if applied to vertical surfaces andwill require priming with Bostik Guardcote when appliedto porous surfaces (see priming).• Check the membrane application for pin holing, ifevident recoat pin holing as necessary to ensuremembrane integrity.MEMBRANE RECOATING and/or REPAIRRecoating (after 7 days following full cure).The surface must be cleaned free of all residue, surfacedust and any forms of contamination present. The surfacecan then be reactivated with use of a clean rag lightlysaturated with Bostik solvent 9934. Apply sparingly with alight buffing/cleaning action.RepairingIf repair of Bostik Ultraseal is necessary, the thoroughremoval of all foreign adhesives or toppings must be carriedout. Ensure the repair area surface is left free of all residue,dust or contamination. Solvent wipe and clean with Bostik9934 as detailed in recoating.In both applications do not pond or flood the surface withexcessive 9934 solvent, as this will soften the existingmembrane surface and may damage/dissolve the filmthickness.After solvent cleaning, isolate the area to ensure themembrane is not recontaminated. Spot repair or recoat themembrane after all solvent has flashed off, usually within 4hours.During solvent cleaning operation ensure adequateventilation and personal health and safety protection isprovided as per Bostik 9934 Technical and MSDS.MEMBRANE PROTECTIONExtended periods of exposure will require the provision ofmembrane protection from following trades. To eliminatepossible surface damage or contamination it isrecommended mortar bedding, tiling or finished flooringinstallations should be carried out as soon as possible afterfull cure of membrane is established.TILE ADHESIVESDo not attempt to apply tile adhesives to any of theUltraseal membrane range whilst the membrane is stilluncured. Tile adhesives must be compatible with the tiletype and Ultraseal, i.e. not solvent based, water clean-up.TILING INTERNAL WET AREAS & EXTERNAL AREASIf direct sticking the tile adhesive to Ultraseal membrane isintended, Bostik Ultra NP Primer or Multiprime 2 partsupplied by Architectural & Structural Adhesives Pty Ltd(ASA) is required to ensure maximum adhesion. The primermust be applied in two coats with a minimum recoat time of4 to 6 hours (at 25°c and 50% humidity). The primer needsto be applied within 7 days of application of the membraneand the tile adhesive applied within 4 days of the applicationof the primer.The adhesives that can be used for tiling include ASAConflex, Asaflex, Fixall with Megalastic additive, or Megafix.Up to date technical literature should be consulted prior toapplication. Product data sheets are available online atwww.asaltd.com.au or by contacting ASA technical advicetoll free 1800 813 890.Alternatively, a polyurethane based adhesive such asPolyflex, Marblefix or Asaphonic can be applied directly overthe Ultraseal membrane within 7 days of membrane curing.If tiling after 7 days consult your Bostik TechnicalRepresentative.The installation of the Ultraseal waterproofing systemsshould be installed as per AS3740 and in conjunction withthe manufacturers instructions. The tile adhesives must beapplied in accordance with AS3958.1-1991 “ Guide to theinstallation of Ceramic tiles – Part 1” and the manufacturersinstructions.PRECAUTIONS• As product literature can be regularly updated pleaseensure the most up to date information is consultedfrom the manufacturer prior to commencement ofapplication.• Due to the state of the concrete, pin holing may occurduring the course of, or shortly after completion ofapplication. Affected areas must be recoated to ensureperforation free membrane coverage is achieved.• Standing water introduced to freshly applied BostikUltraseal or excessive slab moisture may cause themembrane layer to swell. If this should occur, theaffected area should be cut out and replaced with freshUltraseal once the slab is completely dry. (see recoating& repair).• Bostik Ultraseal Membranes are not vapour barriers nordesigned to stop a hydrostatic head of water pressure.(For this application Bostik Moisture Seal, a vapourbarrier, is recommended).• Rate of cure will be inhibited when air or substratetemperatures are below +5°C or if applied over a vapourbarrier or untreated concrete.• Ultraseal should not be applied greater than 2mm indepth in one application as the likelihood air entrapmentfoaming or blistering may occur.• Membranes require atmospheric moisture to fully cure.They should not be used in totally confined or air freespaces.• Mortar bed screeding, tiling or planter box earth fillingshould not be carried out until Ultraseal has cured for aminimum of 24 hours @ 25°C.• Bostik Ultraseal Membranes should never be used as awearing course for foot or vehicle traffic or as anexposed finish or top coating exterior membrane. BostikBoscoseal Torch On Membrane with mineral slate finishsheet is designed for these applications.• Do not apply in temperatures greater than 35°C.• Any intended application of Bostik Ultraseal Membranesoutside of intended use should be first referred to BostikTechnical Division for approval in writing.P.A.T.S (Pretested Adhesion to Substrate)ProgramBostik offer a service in which a program has beenestablished to eliminate potential field problems by pretestingBostik membranes and coatings with samples ofbuilding materials to which the membranes will be applied.This service is available on large projects where preapplicationtesting will aid in determining the proper surfacepreparation method to achieve optimum adhesion. Consult aBostik representative for further information.
