Quary tiles on underfloor heating

Posted by ian and Denise Wagstaff, on
The screed over our new underfloor heating is a special mix for going on top of underfloor heating. I wish to refix the reclaimed quarries in a wet cement bed. Do I use a similar mix to the screed or are there better mixes. Where can I purchase relatively small amounts of any specal component of the suggested mix. thank you

The method is 3 of sharp sand and 1 of cement semi dry mix with a minimum bed of 20mm. The tiles can beg fixed using the a cement slurry mix on top of the screed while still wet. It is a specialist job so carefully. Regards Tony

Hi Ian. It is not unusual for underfloor heating mats to be embedded within a self leveling compound/screed prior to tiling. If this is the case with your project, you will be able to fix floor tiles on top of this using a single part adhesive - available from good tile shops.If you know what the screed is, take this information to the tile shop and ask them to supply the correct adhesive for it.Also, check with them if you need to put a primer on the screed first before applying adhesive. Tikes should be fixed into a solid, notched bed of adhesive. Quarry tiles often need sealing first on the visible side so they don't become stained with adhesive. Grouts are available in various shades of grey which will look like cement colour you are after. You will be probably better using flexible adhesive and grout as they allow a small amount of movement on wooden floors. Hope this helps, Karl

Hi Ian there needs to bed a flexible additive to the mix. If you are adhesive fixing? There is a 1 part flexible adhesive that can be used But will also need to apply the additive to the grout/cement that you use for filling the gaps unless you get the flexible per mix Make sure there is a solid bed of adhesive and in adheres well to the screed. All the best

Hi there, You will be able to buy floor adhesive in small quantities from a local tiling supplier which is suitable for underfloor heating. You will be able to purchase quick drying and even flexible if the floor is wooden.
