RECOMMENDED USES Primer for use with Bostik range of Ultralevel levelling compounds APPLICATION INSTRUCTIONS SURFACE PREPARATION Prime 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 levelling compound. Primer will dry in approximately 40-60 minutes depending on substrate and air temperature. Ensure no ponding or puddles of the primer is evident prior to the application of the Bostik Ultralevel range. Extremely porous substrates such as weather damaged slabs, aerated lightweight concrete ect. May require a second coat of primer to avoid pinholes and 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 per coat. DO NOT APPLY ULTRALEVEL LEVELLING COMPOUND TO UNPRIMED SURFACE. Do not allow a dust film to cover primed area prior to application of Bostik Ultralevel Levelling compound. If this occurs the area must be reprimed with Ultralevel Primer prior to proceeding with application of Bostik Ultralevel levelling compound. APPLICATION For concrete substrates subject to rising damp or moisture a waterproof membrane or moisture barrier is required. It is recommended that Bostik Moisture Seal prior to the application of the Bostik Ultralevel range of products. (Consult Bostik office for further details). For smooth and non absorbent substrates such as ceramic tile, terrazzo, quarry tile, sealed concrete or burnished concrete. Use Bostik Ultra NP Primer NOT Bostik Ultralevel Primer Concentrate. MIXING Bostik Ultralevel Primer is supplied in a concentrate and required mixing and dilution with water at a rate of 2.1 (2 parts water to 1 part Bostik Ultralevel Primer Concentrate) DO NOT DILUTE WITH EXCEES WATER. COVERAGE 1 litre of Bostik Ultralevel Primer diluted with 2 litres of water will cover approximately 8-10m2 per litre per coat. Depending upon the porosity of the substrate.
