1 Technical Data Sheet Ultralevel Bulkout Self Levelling High Build Cementitious Underlay SMF26a DESCRIPTION Bostik Ultralevel Bulkout is a high build, rapid hardening self levelling polymer modified cementitious bulk fill. Bostik Ultralevel Bulkout has been formulated for maximum flow and easy application to achieve a flat surface without any shrinkage or cracking FEATURES Accepts foot traffic in 2 hours. Reinstating large areas in relative short time periods. Very fast application. Dimensionally stable. Single component product, just add water. Installation can be carried out in a single application. Rapid curing. Can be applied directly onto prepared concrete surfaces. Eliminates the need for sand and cement screeds. Floor covering may be applied next day. Economical reinstatements of uneven concrete floors requiring a high build up. RECOMMENDED USES Underlayment of floor coverings such as carpet, ceramic tiles. Fast repairs of uneven concrete floors where thickness of greater than 10mm is required. Residential, commercial and medium industrial application. Application thickness from 10mm edge to 150mm in a single application. New construction and refurbishment projects. Flat smooth surfaces over existing concrete slabs. Levelling existing uneven concrete floors. Economical reinstatement of uneven concrete requiring high builds. APPLICATION INSTRUCTIONS SUBSTRATE AND SURFACE PREPARATION Ensure substrate is clean, dry and free from oil, grease, sealers, curing compounds, paints, polymer coatings, dust or any other contaminant or coating that may affect the bonding of Bostik Ultralevel Bulkout onto the substrate. All foreign material, e.g. bitumen, adhesive or latience must be removed by mechanical means such as scabbling, capture shot blasting or grinding. The substrate must be primed prior to carrying out the application of Bostik Ultralevel Bulkout. Prior to carrying out application the substrate must be primed with; Porous Substrate: Must be primed with Bostik Ultralevel Primer Non Porous: Must be primed with Bostik Ultra NP Primer. New concrete floors must be at least 14 days old prior to application of Bostik Ultralevel Bulkout. PRIMING POROUS SUBSTRATES Prime the clean dust free concrete substrate with Bostik Ultralevel Primer using a brush, broom or roller. Allow primer to reach a tacky consistency before applying Bostik Ultralevel Bulkout. Approximate drying time for the primer is minutes at 50% RH and 25ºC. Bostik Ultralevel Primer is supplied in a concentrate form and should be diluted 2:1 with water, 2 parts water to 1 part Bostik Ultralevel Primer Concentrate.

2 Primer will dry in approximately minutes depending on substrate and/or temperature. Extremely porous substrates such as weather damaged slabs, are rated lightweight concrete etc., and may require a second coat of primer to avoid pinholes or bubbles in the levelling compound. If a second coat is required allow the first coat to dry prior to application of consecutive coat. Apply primer at 8-10M2/litre. Brush out ponded primer to allow for even and complete drying of the Bostik Ultralevel Primer prior to the application of Bostik Ultralevel Bulkout. DO NOT APPLY ULTRALEVEL BULKOUT TO UNPRIMED SURFACE. Primed areas should receive the Bostik Ultralevel Bulkout as soon as possible after the primer becomes tacky so to avoid dust and surface contamination effecting adhesion of the Bostik Ultralevel Bulkout to the primer Refer to A.S Section for allowable moisture content. For concrete substrates that contain greater than 5.5% moisture content or are subject to greater than 70% relative humidity, rising damp or moisture a moisture barrier is required. It is recommended that Bostik Moisture Seal is used. Bostik Moisture Seal should be used as a vapour barrier prior to the application of Bostik Ultralevel Bulkout applied in accordance with Bostik Moisture Seal Technical Data Sheet (contact Bostik Office for further Information). Floors treated with Bostik Moisture Seal should be treated as a non-porous surface and primed with Bostik Ultra NP Primer. NON-POROUS SUBSTRATES For application of Bostik Ultralevel Bulkout to non-porous substrates use Bostik NP Primer contact your nearest Bostik office for Technical Data Sheet. MIXING Bostik Ultralevel Bulkout requires 3.0 litres of clean water per 20kg bag and is best mixed with a forced action, high shear stirrer, powered by a heavy duty electric mixing drill at approx. 600 r.p.m. Add pre-measured water to a clean mixing bucket. Gradually add Bostik Ultralevel Bulkout into the water whilst continuously mixing the contents of the bucket. When the entire contents of the bag have been added to the water, mix for a further two (2) minutes to produce a smooth homogenous consistency. DO NOT MIX BY HAND DO NOT ADD EXCESS WATER Discard any Bostik Ultralevel Bulkout that has hardened or stiffened in the mixing bucket. Further addition of water will NOT reconstitute a useable mixture. APPLICATION PLACING Pour the fully mixed Bostik Ultralevel Bulkout onto the primed substrate and allow it to seek its own level. Bostik Ultralevel Bulkout may be spread with a steel trowel, spreader or squeegee. Keep the trowel blade slightly inclined to achieve the desired thickness of cover. To ensure uniform consistency and continuous flow of the fluid Bostik Ultralevel Bulkout, it is advised that subsequent mixes are ready to enable continuous pouring until the entire area to be levelled is complete. CURING No special curing is required. The addition of water to Bostik Ultralevel Bulkout after it has started to stiffen is not recommended. Any Bostik Ultralevel Bulkout that has not been placed whilst still fully fluid should be discarded. Typical Application: Dual Layer System for Smooth Finishing. Thoroughly prepare the floor surface. Prime the surface with appropriate primer depending on substrate and allow drying. Apply Bostik Ultralevel Bulkout to the required minimum 10mm thickness onto the dry primed surface. After 24 hours prime hardened Bostik Ultralevel Bulkout with Bostik Ultralevel Primer at Primer at 8-10m2/litre per coat, after 2:1 dilution with water (2 parts water, 1 part Bostik Ultralevel Primer) and allow to dry. Apply Bostik Ultralevel SL onto primed Bostik Ultralevel Bulkout. Page 2 of 5

3 COVERAGE A 20kg bag of Bostik Ultralevel Bulkout mixed with 3 litres of clean water will yield approximately 12 litres. This quantity will cover approximately 10mm thick. Thickness Area m2 per 20kg bag 5mm mm mm mm mm mm mm mm Yield 83 bags per cubic metre. IMPORTANT NOTES Concrete substrates must be at lease 21 days old. Do not over water. Do not hand mix. Can be walked on after 2-4 hours. Do not use in external applications. Protect from direct sunlight or drying winds during cure. Do not use in areas subject to hydrostatic head of pressure. Do not use in areas subject to constant contact with moisture. Not recommended as a finished floor coating or wearing surface. Not recommended for application on floor coatings such as acrylic or epoxy. BOSTIK CO-OPERATIVE TEST PROGRAM Bostik offer a service in which a program has been established to eliminate potential field problems by pretesting Bostik adhesives with samples of building materials to which the adhesive will be applied. This service is available on large projects where pre-application testing will aid in determining the proper surface preparation method to achieve optimum adhesion.
