I've bought some mapei Eco primgrip and was going to use a mapei adhesive like keraflex I'm sure I've read on here that should be ok?

£20 for Kerdi Coll now is a lot less than a few grand later on!

I've got kerdi coll, but the only reason I bought the ecoprim grip was on a recommendation from here.

Well if u have it, u should use it, best using Schluter adhesive with Schluter products.
Eco prime is a primer not adhesive.

Well I had bought it originally for the seams and joining my ditra to the kerdi on the former. I had been searching for advice on adhering the fleece to the former and even contacted both schulter and akw and neither would recommend an adhesive.

I had seen on a different forum someone recommended using kerdi fix and then later on using kerdi Coll but no one would confirm it.

So for this reason I went with what was recommended on here, and that was to sand the surface, prime the surface with the ecoprim and combine with a mapei adhesive. Are you saying this won't work?

Schluter wouldn't recommend an adhesive?
Well Kerdi Coll is primarily used for adhering their Keba to Ditra,
Kerdi fix is designed to stick Keba to metals plastics and so on.

No they wouldn't recommend anything to fix down to the former as its something they've never worked with. And Akw only recommended using a paint on system which I wasnt really up for

Well knowing the members that have made the recommendations above as I do, I would be completely happy using any of their methods.
Well I'm the same as Schluter, not done it before.
However, I do know how good Kerdi Coll is, used it many times.
So I wouldn't hesitate to use it.
If u go that route, do not mix it until u are 100% ready, keep the room temp down as much as possible, and don't hang about! 🙂
If you're uneasy about using it, just mix in smaller batches to the correct ratio. Better done in one hit tho.

It was looking through old posts from a user called dhtiling. But I see he's no longer active. Do you think combining the Eco primgrip as apparently it's good for hard to adhere to surfaces (has small grit particles or something I it) and an adhesive like keraflex with latex added will still work then?

That old post is by @Dave above 🙂
Don't worry he's kinda trustworthy! Hahaha
