Excellent bond strength. High grab. Non-sag.
The Frog range's top-tier adhesive — built for vitrified tile and natural stone on internal and external floor and wall, where extended open time and zero slump matter most.
PRODUCT OVERVIEW
Natural stone and large-format vitrified tile don't forgive a weak bed. Frog Stonefix T5 is formulated with extended open time, high initial grab and a non-sag body, so heavy stone slabs stay exactly where you set them — on facades, external paving, and feature walls exposed to real weather.

FAQ
Always test on an offcut first — porous, light-coloured stones like marble can be sensitive to moisture. A patch test confirms there's no shadowing before full installation.
Yes, Stonefix T5 is rated for internal and external floor and wall, including exterior paving over a sound, well-drained substrate.
Large-format and natural stone tiles often have uneven backs. Back-buttering fills the gap and maximises adhesive contact, which is essential for full bond strength.
Stonefix T5 carries the highest classification in the range (C2TE) with extended open time, purpose-built for natural stone and exterior exposure — a step above Megafix T2's tile-on-tile focus.
