A big flooring problem!

[bootsmckiber]

do you know if tiler back skimmed/buttered the tiles as well as spreading adhesive on the ditra?

With slate being porous it usually sucks up the moisture out of the thinset (At least this is what I find)so many(many)years ago I took to the practice of buttering all natural stone tiles and have not had a problem since,I've been called out to check on other jobs why stone is sounding hollow and some coming loose and after turning over the tile it is obvious the tile wasn't buttered as there was maybe just a few lines of thinset holding it down,which after a few months,weeks even it would come loose,have a second tiler or distributor look at your tile and get his opinion,but this sounds exactly like what I experienced some 25 years ago,if that's the case,it's the tilers fault,especially with 30 years under his belt,Good luck,Mike

generally screed takes 1 day per mm so 65 days ish should be fine, cant see moisture remaining in the screed afetr the period you talk about.

cheers

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

Yep new G mat looks just the same as new Dural ci+, just a different colour, same squares and circles. Sorry the pics are not very good.

never used matting before.
ive got a bigish slate floor to do shortly,mostly new concrete but where they have knocked through it goes onto ply,would you recommend this matting(i may have to SLC the ply to get the right height,can't remember i aint been for a few weeks since plastering it out)or would a expantion joint do the trick?

ps,i jumped up and down on the ply floor,its solid as,no deflection

I would defo put an expansion joint between the two substrates, but if there is no underfloor heating, then why not use backer board on the timber floor to bring it up to level....

i can't remember the thickness or which way it went,its been a few weeks since i was there and with my brain each job rolls into one so not sure if the concrete is high or the ply,would want the ply to be low,so i could either SLC it or board it,depending on thicknessi don't want to slate onto ply,im not a great fan of ply

i was going to put a expantion joint in stewart,but ive never used matting before,ive heard good things and bad things on here about it so was just wondering,but would rather not do it cos of the price of it
cheers mate

Why does everyone use Dural these days never had a problem with Ditra?

 

[The Legend; Phil Hobson RIP]

Cheaper mate, although you do have a point

Half the price !! JUST AS GOOD !! Schluter would like you to believe that their product is the best, it may have been the first,but things move on.DURAL for example,the director Gerrard has been in the industry for many years and had worked for Schluter,Genesis and many others.You are in no way getting an inferior product..... just a different colour and slightly different indents.
This is why Schluter have had to reduce the price of their matting.They no longer have the monopoly.There are some similar that I would not use, mainly due to cost and also adhesive useage filling holes, but Dural is top notch.
Buy direct it will save you a fortune.

Aah aman.. just spent 20 mins reading this and then .... no resolution / update / pictures. What a tease! :lol:

 

[ms.tiles]

yeah come on.....
What happened with the floor????????????

 

[Dan]

Just bumping some of the older popular (sometimes not so popular) threads. Probably wont be current discussion these days but I just need to do it. So just ignore the thread if it's not current for you.

I would have a guess it was the old matting and the fleece has come away from the plastic, it happened to me on a few jobs. Dural came out drilled holes in grout and injected with resin it solved the problem.
Dural were also supplying porcelanosa with it but blue and l had a couple of failures aswell. The dural rep said we have stopped repairing now. As we have over a million m2s to fix and it will bankrupt us. Hence porcelanosa have designed there own and it's awesome no where in the make up of it to fail. I only use that or kerrakol hydro build.
