A big flooring problem!

[jay]

as alan says if it comes of clean of screed its the tilers prob poor prep work wrong primer would appreciate some pic thanks

Just another thought, I have seen tilers putting Ditra down with a 4mm trowel that has been used to much and has worn down to the nub! Tiled over it and then the tiles lift and crack. Perhaps the mat was never bedded down properly in the first place.

Look forward to seeing what happens when the tiles are taken up. Please keep us posted

Have you had a resolution to your problem?

Have you contacted Dural ? I can see an ongoing argument between screeder and tiler and no one will ever find the true answer.

I have 8 bathroom floors and 40m2 kitchen floor being sorted out by dural at the moment (all on timber floors all installed as per manufactures instructions). I was told by them not to use the original yellow matting any more as there is a fault with it, they now have a new version of the matt from a diferent manufacturer still yellow but with 2 different shapes in the plastic and new fleece also 2 top mesh layers in opposing directions one of which is green seems better. I had a problem with 1 floor over 12 months ago that Dural fixed for me but didnt tell me there was an ongoing issue with the matting. I have been using this matting for 2 years now and I believe there are more problems still to come.

Hi Bubbles, when you say timber floors. Do you mean 15mm/18mm ply? not T&G or chipboard? I would never use a decoupling membrane on anything but ply 15mm minimum.

 

[BubblesTiling]

Hi Phil, I have used the membrane on all floor types only after speaking to the suppliers who told me there would be know problem, I wouldnt normaly tile onto any timber other than ply, but was assured it would be ok onto T & G and chipboard with the correct priming prior to fitting though I am regretting it now. Although Dural have been very good and have held there hands up and are sorting out the issues without ripping up the floors. All of the tiles and the grout joints are perfect no breaks or cracks just a strange crunchy noise under foot!!!

So the failures you have are susceptible to lateral deflection? From that it would appear that maybe there is a problem with it as they could quite easily put it down to installer error as their own instructions recommend screwing floor boards and over boarding where necessary.

 

[BubblesTiling]

I would always secure all floor types regardless, with good quality screws preferably 80-100mm straight into joists to pull it tight. theres no point tiling onto a floor if it has movement prior to instalation.I believe my problems are from settlement in renovated properties. I have the same problem in 2 houses 4 bathrooms in each all fitted as per manufacturers instructions, the fault seems to be inherent in the matting as the Dural Rep has told me never to use the original matting again even though I still have some left over.

Hi Bubbles, I am sorry to hear you have had these problems. I rate Dural ci mat greatly, but mostly for it's decoupling capabilities ( lateral movement etc) especially over ufh. I do not think it offers much in the way of overcoming deflection ( bounce) on timber floors. I would never tile on T&G or chipboard without overboarding. Good luck with it.

Thanks Phil,

I use Dural for most jobs now especialy as people like the idea of not having floor height issues, no big step like if you have to overboard rooms, the new product does seem to be much more robust than the original, have you used it yet?
How are you getting on with the drytreat? I find it much better than most other products and customers realy like the guarantee. Much easier to use as well, though you do have to lay it on thick to use the recommended amounts as set out on the web site. Bit of a way to get extra sales me thinks.

Cheers

Hi Warren, I have not used the new Dural mat yet. I think I maybe using it on a big flooring job soon. As for the drytreat, I could not be more impressed top stuff imo, if it does what they say in the long term from me.

Hi Keith, yes it did kind of fizzle out:lol: I have used the new Dural mat, and am just about to use the new G mat from Genesis. It seems there was a problem with the old mats, and quite a few people have had failures.

New G-mat!! ?


Is it the same profile as Dural Ci+.?

 

[The Legend; Phil Hobson RIP]

New G-mat!! ?


Not sure Dave, I start a job on monday with it. Getting it from CTD, so I will let you know, don't think it can be the same as Dural for legal reasons. Only a guess
