Description
SikaBond T-55 J is a 1-component elastic wood flooring adhesive designed for full-surface bonding of solid and engineered wood floors, with good workability that makes it genuinely easy to spread evenly across a large floor area. Its elasticity does double duty: it reduces stress transfer between the timber floor and the substrate, which both protects the flooring from substrate movement and provides genuine footfall-sound dampening.
Being sandable, with the floor walkable after just 12 hours and ready for sanding after 24, gives a fast, practical schedule for a full-surface bonded timber floor compared with adhesives that need longer cure times before the floor can be worked on. Its ability to bond directly onto old ceramic tiles is a genuine advantage for renovation jobs, avoiding the cost and disruption of removing an existing tiled floor before laying new timber.
Its elastic, footfall-sound dampening properties are a genuine benefit beyond just holding the floor down — by absorbing some of the natural movement and impact noise of a timber floor, SikaBond T-55J helps reduce transmitted footfall sound to spaces below, which matters in multi-storey residential and commercial buildings. Being suitable for direct bonding onto old ceramic tile also avoids the cost and disruption of tile removal on renovation projects, while its compatibility with underfloor heating extends its use across a wide range of subfloor types.
