It is important to select the correct trowel for the application to maximise both adhesive footprint and coverage. Selleys have designed a specific trowel for the application of LNDS according to the following specifications. Consult Selleys before using a different trowel to that recommended. Technical Data/Properties Contact Selleys before using this data for the setting of specifications. Property Typical Result Colour Beige Density 1.4 Technology Polyurethane Coverage 1.5 - 2m2/Litre Application Temperature 10 – 350C Shelf Life 12 months Working Time 30 minutes @ 25C Cure Time 24 hours Tensile Strength 1.5 MPa Shear Strength 5.2 MPa VOC 93 g/L Important Notes/Limitations  Cure rate will be inhibited if air or substrate surface temperature is below 50C.  Selleys Technical Services should be consulted if any doubt exists in respect to floor contamination, or any concerns in relation to moisture.  Should a self-levelling compound be required, consult manufacturer in relation to drying times and appropriate priming to adhere the compound to the substrate. Selleys recommendation for self-levelling compound is Roberts Flexiscreed 38 or an equivalent exterior grade product.  Selleys recommend that Liquid Nails VBS Vapour Barrier be used over a levelling compound as moisture rising from below can affect most overlay flooring.  For maximum bonding between the Liquid Nails VBS Vapour Barrier and LNDS, it is recommended to lay the adhesive within 24 hours of applying VBS. If LNDS is to be applied to VBS after 24 hours have elapsed then the surface of the VBS will need to be roughened with 60 – 80 grit sandpaper.  Timber strip should be installed at a measured moisture content within 2% of the expected equilibrium moisture content of the building to minimise excessive movement after installation. www.selleystrade.com.au Page 2 of 3
