are you getting them from a local firm or from the net since gulf stone went bust theirs a lot of cheap poor quality quartz on the market. the poorer the quality the harder to stick down what ever addy you use.

It's not suitable and, in my opinion one of the worst s2's I've ever used

As an S2 it's not as deformable (flexible, bendy) as some like BAL fastflex or Mapei S2 but in my experience it bites into substrates like metal, fibreglass and resin like nothing else (aside from Fastflex and Mapei S2) so in that regard I think it's a brilliant adhesive at a very good price point.
Remember - S2 isn't even a proper classification, more of an optional extra.
Anyone can make bendy adhesive - the bite and adhesion onto difficult substrates isn't so easy.

I find it same as sticking any tiles down. The problem is with water content of adhesive. Well, that and ufh and sunlight.
Apart from that it's fantastic

How many single part s2's have you removed from said substrates then. Just so we have a decent field of example

I did a test just this week on Porcelanosa's air slate, (didn't like the supplied epoxy grout for fixing) along with some steel sheet and the Ultimate had the best bond on both.
Not as flexible but definitely keyed into each better.
As for fibreglass, I only used it once on a pond siding/waterfall feature but again, the bond was brilliant.
I think I'd prefer fastflex on a timber floor because I know it deforms well though.

Why do you say not suitable and what's your experience?

Just realised i didn't answer the question!
Only 3 - TM ultimate / BAL fastflex and Mapei S2 ultraflex

You've used those 3 on which substrates? And have you had need to remove any tiles or just guessing at bond strength and adhesion?

It's just the water content. Tilemaster put a post in here a while back stating they've had many successful installations but no guarantee. Why wouldn't you use a 2 part?

Just to recap here @impish, you've used 3 s2's and tm's ultimate is in 3rd?😵

Depends what you want or expect from an S2 I guess.
For me, it's problematic substrates such as fibreglass/resin on the Air slate. I know S2 to most people means bendy/flexible though, so in that regard Ultimate isn't in the lead.
I wasn't defending it's use for man-made quartz - I agree the water content would be a factor.
It's years since I fixed the stuff but I used old Fast-flex 2 part and more lately BAL PTB with no issues.

I just hooked onto the bit where you said it's one of the worst S2 you've used and tried to offer another opinion is all 🙂

So for me, I have a problematic substrate and think "S2" and Ultimate will likely be my first choice these days.
If I want the flexibility though, then it's BAL fastflex.
