The easy way to fix tiles over underfloor heating

Smooth, stress-free tiling over UFH.
Laying tiles over underfloor heating doesn’t have to be a headache – just use Kerakoll’s systems for both electric and water-based setups. They’re simple to work with and have no nasty additives to damage your health.
Encapsulate your system with Proflow Finish
Once your carrier board and pipework are in place, prime the surface and grab Proflow Finish to level and smooth before tiling.
This self-smoothing and levelling compound is built to handle the expansion and shrinkage that comes with underfloor heating. It’s a true all-rounder—moisture-tolerant, suitable for any installation, any substrate, and any resilient flooring, up to 60mm deep.
Plus it's got:
A free-flowing formula for effortless application
30-minute wet edge time for flexibility
A rapid setting time – ready for foot traffic in just 3.5 hours
An EC1-Plus GEV Emicode rating (so it’s low in emissions)
Tile with H40
Once the substrate’s dry, it’s time to fix your tiles. For this, Kerakoll’s Gel-Adhesives are the way to go. Choose from H40 Gel – Standard-set for general use, or H40 Advanced & H40 Ultimate – rapid-setting options for when time’s tight.
All three adhesives work with any tile, and any substrate, thanks to their advanced polymer formula, which gives them serious shear strength. They’re ideal for underfloor heating too, as they’ve got flexibility-enhancing additives that help absorb movement stresses between the substrate and the tile.
