Hi all,

If you've read any of my threads lately, then you will know that we are moving into a new build house and will be adding a large conservatory on. The whole of the ground floor is quite large anyway but with 2 rooms being carpeted, we are looking to get a total area of around 70 square metres tiled on top of the underfloor screeded (wet) heating system.

Researching around seems to say that I need a decoupling matting such as Ditra matting between the screed and the tiles and while buying this myself is £520 for the size I need, it would still need laying with adhesive so makes sense to get a tiler to supply and fit it I guess.

Calling around for prices, speaking to a few people, I've been getting prices of around:

£35 per square metre including grouting and adhesive
£15 per square metre including the decoupling membrane matting

Does this sound about right? As you can appreciate, across 70 square metres, this is adding up quite a bit and I still have the price of tiles on top.

Thanks in advance,

Andy
 
We had wet UFH fitted in a 50sqm extension last year. There was no mention of such matting from the builders, plumbers or tilers.

What is the purpose?

I see. Our UFH pipes were clipped to the insulation, and screed poured on top.

Then we had dehumidifiers going for about 10-14 days before the tiling started.

Yeah similar to what we are having (a clip rail system on top of the insulation) and then quick dry screed on top which I've been told should be dry and ready for tiling in 7 days.

So you didnt have to have any membrane down? Just tiles directly onto the screed? Any cracks etc...?
 
IIRC decoupling matting is most important if the concrete is relatively new and hasn't cured fully (can take years). That said I think there are also liquid decoupling membranes on the market, which may be substantially cheaper, especially for that size.

Yeah, tiles straight onto the screed.

No cracks. Once it was done we were told to turn the UFH on very low and gradually increase the temp over a couple of weeks. Over a year on, it's all in one piece.

I think 2 weeks was the minimum we had to wait for screed to dry, and with 2 dehumidifiers going 24/7, they had only just stopped filling up by then. Official guidance was something crazy like 40 days, but builders and tilers said 2 weeks was fine. Maybe the membrane is needed if tiling sooner?
 
Have you decided on your tiles? The type and format can have an impact on the cost of installation.

I am 2/3 of the way through laying 100 square meters of modular porcelain tiles through most of our downstairs. The tiling isn't too bad but the grouting & resulting cleanup is soul destroying. If I had the spare cash I would be paying somebody else to do it!
 
Same here, tiles straight onto screed.
The only cracks we have had have come from dropping stuff on them :mad:

Yeah it will be very new hence why o think we needing the membrane costing £1050 including fitting.

Yeah we are going for quick drying screed but soeaking to two tilers today they both recommended the membrane.

Thinking porcelain but will be having a big look tomorrow at various tile places. Yeah based on the size I really don't even want to think about doing it myself.

How quickly were the tiles laid onto the screed after it dried?

I cant remember exactly, it was between 3 & 4 weeks.
I did mine and a friends at round about the same time and his was a similar timescale.
We put fibres in the screed thinking back.
