ULTRASET^® SF

Bostik Ultraset^® SF is a solvent-free, one-part polyurethane adhesive, proudly made in Australia, formulated to bond most types of parquet, solid strip, engineered, bamboo and sheet timber flooring to concrete and timber subfloors. It won't re-emulsify with water and remains flexible after full cure, giving a long-lasting bond that moves with timber as it expands and contracts.
Suitable for use over radiant heating, it's a trusted choice among flooring installers for its strong bond and excellent acoustic properties, backed by recommendations from major timber manufacturers.

Why choose Ultraset^® SF?
It's solvent-free with zero VOC and non-flammable, and needs no mixing, so it's ready to use straight from the pail. Once applied, it delivers excellent bond strength and acoustic properties, and stays flexible long after curing, helping timber floors handle natural movement without failure. It's tested to ASTM C794 for peel adhesion across Australian hardwood species and meets EN 14293:2006 requirements for bonding parquet to subfloors.

Where to use it
Ultraset^® SF bonds parquet and finger block parquet, solid strip softwood and hardwood flooring, engineered flooring and bamboo flooring to concrete subfloors and to plywood, particleboard, joists or battens using the bead method. It also works as an intermediate layer with acoustic underlays.
Dense, burnished concrete should be abraded or sanded first to create a mechanical key.
