It is available in a 3.6L kit, which is sufficient for 20m2. Uses  For sealing concrete floor slabs to reduce the amount of water vapour emanating from the concrete.  Suitable for use on concrete slabs prior to using Selleys flooring adhesives to lay timber overlay. Features/Advantages  Normally a one-coat system.  Colour coded components to aid proper mixing  Controlled opacity: - The dark green-pigmented colour of the mixed product helps the applicator to gauge a consistent application rate by eye.  Rapid cure  Very low water vapour transmission rate.  Excellent adhesion and application properties  Optimal properties for subsequent bonding with Selleys flooring adhesive Instructions for use/Application Instructions The following should only be used as a guide and the installer should apply all Australian Standards, BCA/NZBC requirements, and best practices. Preparation  Selleys Liquid Nails VBS cures rapidly. Ensure that all your preparation is complete and the application area is clear and marked out before commencing mixing.  Product is supplied ready to mix and use.  For application use a 5-6 mm mohair roller (or an applicator to minimise splatter) and cut in with a paintbrush.  All surfaces must be clean, dry and sound, free of voids, loose materials and contaminants (curing compounds, oil, grease, waxes, sealers, previous coatings or adhesives, etc).  Complete removal of any contamination must be carried out where it is suspected or evident.  Surface preparation may be achieved by diamond grinding, shot blasting, sand blasting, and captive abrasive blast cleaning (Blastrac) or other suitable method. (Acid etching is not recommended, as the concrete has to be neutralised and dried afterwards.)  Best preparation is to diamond grind the surface of the slab, as it enables the removal of high spots as well as laitance.  Surface shall be structurally sound and level. Concrete slabs shall be in accordance with AS2870-1996 Residential Footings and Slabs Code.  For best results and optimum coverage concrete surfaces should have a finish equivalent to that obtained when using a steel trowel.  VBS can be applied if the concrete surface is dry and the slab has stabilised. To be stable, new concrete should be cured for at least 28 days or until the moisture content of the slab is less than 5.5%. www.selleystrade.com.au Page 1 of 3
