Re: what is best proceduref laying stone on to old concrte base in chu

My current thoughts are:
ball p131 primer.
ball green bag withh 114 additive to smooth out rough concrete base.Only thinking of this latex as compatible with base that has moisture in it, because of no Dpm.
ball stop 75 liquid Dpm followed by ditra mat fixed with flexible adhesive.
fix stone on top of ditra with setaflex.
what do you think ?

Any thoughts welcome

Save you some time

products

Thanks . This sounds like the ball stop 75 so we are thinking along same lines.
Liquid resin Dpm seems logical

Jonny, you've just given a very similar spec to what I've used a few times when laying vinyl floors. P131 (Which I still use more than any other primer) We used a different latex and then Laybond DPM. As we were laying vinyl the DPM was latexed over again but had to be primed first. All I would say is check if the DPM you use can accept the tile adhesive directly or if it should be primed first. Can't remember if neat 131 was used to prime it or if something else was supplied.

I am not set on using ball products. They are just the only one looked at so far.
i will definitely use tilemaster adhesive but don't think they have a liquid Dpm or latex suitable for overlaying a subfloor with no Dpm.
i would rather use same manufacturer throughout.
is lay bond best price for this type of latex required .

hi jonny, i have done a church in germany years ago and this was a special thing. we had to use grave for the ground, then a lean concrete and absolutly no waterproofing because otherwise you got the water in the walls. but this was in the ground floor without wood and so on.

I'm not sure about pricing Jonny, I was doing this as a subby and all materials were supplied.

Ive had a look at levels and they are pretty shocking. There is 40mm variance in the base and i am restricted by a number of doors where stone must come flush.
will have to not lay level and just work to each door.
i cant go over 10mm bed as tiling on top of ditra as that is the max they allow so will have to make up some of the dips and low points which are not near the doors in extra levelling compound with granite chips .
what i am looking for is a latex that can go on subbase which has little damp but can have granite chips added which is not too expensive.
Best price i can get on ardex na and bottle is £21.40 and green bag and 114 £ 16.50.
Anyone know of a cheaper latex than this that does same job and where to buy cheap granite chippings.
