Flexible silane adhesives from Bona differ mainly in how they're applied rather than what they're built for.
Choosing by Application Method
Both R848 and Quantum T are one-component, elastic, silane-based adhesives suited to full-spread bonding of solid or engineered wood floors — the real difference is format. R848 comes in a 15kg tub for standard trowel application, and is specifically confirmed for solid wood boards up to 190mm wide. Quantum T is supplied as a 5400ml sausage for gun application, offering a higher-viscosity, rapid-setting alternative that works on nearly all subfloor types.
Shared Silane Benefits
Both adhesives share the practical advantages of Bona's silane-based range: they're safe and clean to work with, leave no black finger marks, and any spills clean up easily — a genuine consideration on a job where mess costs time.
