About

Getting the glue right is what keeps a timber floor flat, quiet and bonded for decades. This collection brings together the flexible MS-polymer and one-part polyurethane wood flooring adhesives EcoGrit stocks for direct-stick installation over concrete and plywood, plus the primers and levelling compounds to prepare the subfloor first. It is built for flooring trades and serious DIY installers working with Australian hardwood, engineered boards and parquetry. The right choice depends on the timber, board width and slab moisture: wide solid boards move more with seasonal humidity and need a highly flexible bond, while most engineered floors are more forgiving. If you are new to glue-down, read our adhesives for timber flooring guide , check spread rates on each technical data sheet , and for occupied indoor jobs choose our solvent-free adhesives . We stock buckets and 600ml sausages from Siegel, Berger-Seidle and Mapei. How to choose Solid vs engineered: wide solid hardwood needs a highly flexible MS-polymer such as SiegelBond PRO98 , a 4-in-1 that also primes and blocks moisture; most engineered boards bond well with BergerBond M1S . Match the adhesive to your species with our timber species flooring guides . Slab moisture: test the concrete first.
