Timber Floor Adhesives
Silane-based parquet adhesive that glues the boards, blocks moisture, and damps sound -- all from one product in a 9kg sausage.
Why silane adhesive
Older parquet adhesives were polyurethane or epoxy based -- they worked, but they contained isocyanates, released measurable VOCs during cure, and stained timber if any squeeze-up reached the surface. Silane technology solves all three problems.
Bona Quantum T uses silane-terminated polymer with titanium cross-linking. It cures by reacting with ambient moisture in the air and substrate, not by releasing solvents. The result is zero VOC, zero isocyanate, and a flexible bond that absorbs the seasonal movement timber floors go through without cracking or delaminating. If adhesive squeezes up between boards, it wipes off the surface without staining -- a significant advantage over urethane adhesives that leave permanent marks.
The product
Bona Quantum T -- 9kg Sausage
Single-component silane adhesive supplied in 9kg foil sausages. Load the sausage into a standard pneumatic or manual applicator, cut the end, and apply. No mixing, no measuring, no waste from buckets that skin over mid-job.
Quantum T is a 3-in-1 system: adhesive, moisture barrier, and acoustic layer in a single application. On concrete substrates with residual moisture up to 75% RH (per ASTM F2170), Quantum T bonds and blocks moisture transfer without a separate membrane. The elastic bond also provides impact sound reduction, meeting the acoustic requirements on many multi-storey residential projects without a separate underlay.
The OptiSpread UX trowel
Bona designed the OptiSpread UX specifically for Quantum T. The notched trowel controls bead width and spacing to deliver the correct adhesive volume per square metre -- too little and the boards hollow, too much and squeeze-up becomes a cleanup problem. The OptiSpread UX trowel takes the guesswork out of spread rate and gives a consistent bond line across the full floor.
Coverage and calculator
Coverage depends on board width, subfloor flatness, and trowel notch pattern. Typical consumption runs between 1.0 and 1.5 kg per square metre. The Quantum T calculator takes the floor area and board dimensions and returns the number of sausages needed for the job -- no over-ordering, no mid-job shortages.
What it sticks
Quantum T bonds solid hardwood boards up to 22mm thick and engineered boards of any thickness. It works on concrete, plywood, and existing tiles (with appropriate preparation). Compatible with radiant heating systems -- the elastic bond flexes with the thermal cycling without cracking or debonding.
