The Advanced Polymer Technology formulation contains no polyurethane. Uses  Engineered overlay (Prefinished and Bamboo) and most types of wood flooring to common substrates such as plywood, particle board, pre-existing strip flooring and FC (Fibre Cement) sheets, concrete, acoustic matting, etc. Features/Advantages  Superior coverage – Advanced formulation provides superior adhesion, allowing greater coverage - 20m²/10L pail using Direct Stick trowel on plywood substrate  Trowel grade adhesive  Easy to remove from prefinished floor boards, tools and hands  Easy to spread even at low or high temperatures : 5°C to 40°C.  Excellent adhesion to most building materials  Low VOC to meet Green Building Council requirements  Flexible  Excellent ridge formation & stability  Good wet grab and initial hold  Isocyanate free formula  Solvent-free formulation 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 when installing a timber floor with Liquid Nails Timberflex.  All surfaces should be clean, sound and level to 3mm in 3m. Out of level floors will increase the risk of hollow spots under strip timber overlay.  Liquid Nails VBS Vapour Barrier is recommended over concrete before applying Liquid Nails Timbeflex to prevent moisture migration and subsequent swelling of the timber overlay. Moisture content of the slab should be <5.5%, and moisture vapour transmission <15g/m2 per 24hr.  Concrete surfaces should have a finish equivalent to that obtained when using a steel trowel.  Grind concrete to remove high spots, surface contaminants and weak surface layers.  Sand timber substrates to remove contaminants such as old glue or surface finishes and flatten any raised joints.  Scoop or pour adhesive from the pail to the application surface. Use a Selleys Direct Stick trowel to spread as much adhesive as you can cover in 20 minutes. It is important to achieve at least 85% adhesive coverage between overlay and sub-floor to avoid hollow spots and drumminess. For direct stick to concrete use a 6mm v-notch at 13mm centres; for parquetry use a standard 3.2mm v-notch.  This provides the optimal spacing and height for adhesive ridges for bridging any gaps between overlay and sub-floor and wetting onto the underside of the boards. Set strip overlay or parquet directly onto prepared adhesive with a minimum of sideways movement using adequate pressure to ensure adhesive contact on each individual board  Fastening (or weighting) is recommended to secure timber during curing.
