It is off-white in colour and available in a 10L pail. Uses x Adhesion of acoustic underlay x Rubber mat x Cork Features/Advantages x Coverage rate of 20m2/L from a 10L pail x Excellent adhesion to most building materials x Low VOC x Flexible x Good wet grab and initial hold x Easy spread with V-notch trowel 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 using. x All surfaces should be free of excess dust, clean, dry and sound. x Liquid Nails VBS Vapour Barrier is recommended over ground level concrete before applying Liquid Nails Matstik to prevent moisture migration and subsequent damage to overlay. x Contractors should test lay a typical sample and do a destructive pull test to confirm adequate adhesion to a given substrate x Use a 2.4mm V-notched trowel to spread adhesive over substrate x Only spread enough adhesive where mat can be bonded within 20 minutes. x Roll or set acoustic mat directly onto prepared adhesive using adequate pressure to ensure adhesive contact between substrate and acoustic mat Technical Data/Properties Contact Selleys before using this data for the setting of specifications.
