One for Ajax!

Lafarge Agilia range covers, Screed A, Gyvlon and Horizontal a flowing 10mm aggregate screed, the Horizontal would generally be installed at 75mm.
I would check with Lafarge which Agilia products it is, and we can then best advise on the way forward.

Hiya.
Don't forget these screeds will need sanding, that needs to go into the price.
I saw a Horizontal screed being poured then waxed, then builder was convinced it would need no prep work, when i asked him about the wax and how he was going to remove it, he had no idea!
As the guys say homework is key for these screeds, don't rely on the builder.
If it's of any help i've used both H40 and GBTA adhesives and the H40 feels much like a single part flexible adhesive in consistancy and use, but i can't say i was inspired with how it stuck. The GBTA is weird at first to work with, more like a pourable thick bed feel to it, took a good while to get the mixes consistant, either too runny or just too stiff, but once i got used to it it was fine to use, and i felt more confident in how it actually stuck. It's bloomin expensive though!

Yes the agilia screeds (apart from the anhydrite) will be sprayed with a curing agent. This is often waxy and will require removal. Also a moisture test is essential because the wax is designed to keep the moisture in the screed (hence curing). It may be that it needs further drying once the curing agent is removed.

The newer Agilia range has a 'built in' curing agent, so may not have been sprayed, but the screed should still be sanded and prepared in the 'correct' manner.
I have heard a few people mention the GBTA addy is strange at first till you get used to it, not heard much re the H40 not sticking well, was there a particular tile type that was on?

I used it with stone and porcelain Mark.
I'm not saying it was no good, it just didn't make me go bloomin 'eck that's stuck!
But you do find these days that the adhesive will either stick to the substrate well and the tile will come away clean, and for other adhesives the opposite. You rarely see it as you often used to pre porcelain days where everything had just stuck in one lump!

I know Kerakoll are doing an open evening in Leeds next wed night at Wheatwood Hall, where they are demonstrating a few products, with H40 being one of them, maybe some members would like to go along and ask some questions.
