Mapei users - What to use for slate?

[infidel]

Have honed slate to lay on half tounge & groove, half concrete floor. 22 sq/m total.
Anyone know what Mapei make that can be used for the job??

Cheers, Martyn

I dont deal with mapei infidel mate but make sure you put expansion joint where the two substrates meet......if you are wanting to go straight onto floor boards then mapei site recommend ultramastic......

dhceramics, cheers for that mate. I've got some Ultramastic III , but was wondering if it's ok for slate.
What sort of expansion joint do you recommend?

Cheers

With it being slate it is to wide a joint for Silicon so i would use a schluter one...
