UNDERFLOOR HEATING A SIMPLE FIX
Kerakoll explains how to fix tiles over underfloor heating the easy way.
Laying tiles over underfloor heating need not be complicated if you use Kerakoll’s systems for both electrical and water- based installations. The products are easy to work with and kind to the health of the installer.
Once the carrier board and pipework are installed, the whole surface should be primed and then Proflow Finish used to level and smooth the floor before flooring installation.
Proflow Finish can easily cope with the expansion and shrinkage caused by underfloor heating. This single component self-smoothing compound is a true all rounder, moisture tolerant and suitable for use in any installation, on any substrate and with any type of resilient flooring at depths of up to 60mm. It has a free flowing formulation, a 30-minute wet edge time, and is able to accept foot traffic and floorcoverings after 3.5 hours. It has an EC1-Plus GEV Emicode rating.
“PROFLOW FINISH SELF- SMOOTHING COMPOUND IS A
TRUE ALL ROUNDER, MOISTURE TOLERANT AND SUITABLE FOR USE IN ANY INSTALLATION.”
Once the substrate is dry, you can fix the tiles. For this, we recommend using Kerakoll’s Gel-Adhesives: pick H40 Gel for standard-set, and H40 Advanced or Ultimate if you want a rapid-setting adhesive.
All three of these formulations (standard setting H40 Gel, rapid setting H40 Advanced and C2 H40 Ultimate) can be used with any type of tile on any substrate due to

the inclusion of new polymers to give them a high shear strength. The Gel-Adhesives are perfect for use with underfloor heating as they contain additives to increase flexibility. The unbroken structural bond which they form with the substrate and tile absorbs and evens out the stresses caused by movement of the substrate.
They are easy and pleasant to work with as they stay the same consistency as when you first mixed them even after a long period in the bucket. The mix doesn’t shrink due to the inclusion of a geo-binder, so you can make it the right thickness for the job, and it is soft and easy to work with. The consistency means that the adhesives wet the entire tile as well as the substrate, giving an excellent bond and superior performance. They also have a very low environmental impact with low CO2 and very low VOC ratings and a large amount of recycled material in them.
Finish the installation with Fugabella Color. Safe and easy to work with, this is a new generation Resina-cemento hybrid grout. It does not contain Portland cement, so it does not develop efflorescence. It has the same advantages as the H40 Gel-Adhesives, allowing you to mix it to your desired consistency and not drying out in the bucket. There are 50 different colours available, making it easy for you to pick one that fits with the colour scheme of the room.
