Whats the best large format tile adhesive anyone has used for solid concrete bed floors without underfloor heating??

Take a look at mapei P4 ....3mm to 20mm bed.......

I've always used Ultra (spf) without any probs

Re P4 I see the little black says 'pourable' Dave (like a leveller, it says) Do you use it runny or as the norm. (Got some 600 sq porcelain coming up)

i used to use the dunlop large format which goes up to 20mm and is suitable for porcelain , i changed brands last year to palace but havent used the p.t.b yet .

Profix flexible fast set. £8.19 a bag from CTD at the moment - great stuff!

John........PTB....is pourable thick bed.......can also be used as a leveller but expensive way of doin it..lol...

Yes you do mix it wetter than normal......towel with your SB trowel and fix....it sort of levells under the tile creating a solid bed.....but when mixed thicker can be used to greater depth.....PJC uses ptb adhesives a lot......i have used them occasionaly but tend to manage with standard bed adhesive as i prep well before hand...

Cheers Dave, already put in my quote if I don't like the floor it's getting a leveller on it, not in P4 form I hasten to add

What was the reason for changing to palace?
Is Dunlop not the same as BAL anyway?

Not loyal to any one brand, any single part rapid flexi and what ever CTD can offer me leveller wise. This floor (hidden by vinyl at the moment) has a couple of 'lumps wich look suspiciously like pipes but we will have to wait and see

I have a similar floor to do in Durham. Not sure about what adhesive is safest to use. Any thoughts?

toppfix flexi-£13 a 20kg bag

my supplier decided to put 50% on with out discussing it with me, dunlop isnt quite the quality of Bal but the large format was good and i would recomend it
