I'm a new member..Hi to all !
Had wet underfloor heating system installed in new garden room. Screed was laid over pipes and then self levelling comound applied. Floor has been down 6 weeks and heating up well.
Now ready for tiling and have bought Courtyard Mews tiles fron Wickes.
Need advice on 2 things please.
1 Wickes do not have coloured grout to match the tiles (dark grey). any suggestions?

2 Is it necessary to use flexible adhesive under the tiles?


Thanks in anticipation......

Ivan

Hello and welcome to the forum.

Question number one - Mapei do a brilliant range of coloured grouts and several greys.

Question number two - Yes you will want a single part flexible adhesive, probably grey if you are going for grey grout. I would go for Mapei's Keraquick grey myself but be careful as this is a rapid setting adhesive and if you need more time to work with it, you may be better off going for a standard setting one.

Do you know if there is a Tile Giant near to you? Have a read through the link below, if so, pop in there and tell them what you are after and they should be able to sort you out no problem


Mapei: Tile Giant Store Finder...

Many thanks Rich for your prompt response and advice. I used your link and have found 2 Tile Giant stores within 8 miles......didn't know they were there !!
Will go there with a tile, match the colour and buy adhesive.
Thanks again - top man

another satisfied customer ,

I love it when a plan comes together

The Adhesive MUST be flexible as should the grout. BAL do a range of coloured grouts to suit and you most are now flexible, their micromax range should have something suitable, you can buy a non flex grout and mix with an additive to make it flexible. Do ensure that the adhesive is flexible, single part or 2 part would be fine but be careful with rapid settings adhesives

Don't forget to turn the UFH off before you tile you need to let the floor cool down, then after tiling wait for 21/28 days before swiching on. You need to raise the temperature gradually, there are threads on here that will give more details. Also adhesive manufacturers can give you further advise.

Many thanks Afenteman and Waterfd for the additional information - I certainly hadn't realized that we would have to wait that long before we turned the ufh back on ! Better dig out the old electric fan heater then !!
Cheers

The time is for the adhesive to cure fully and is not forced through heat.
