What brand is a purple colour adhesive used for gripper rods?

I went to do an uplift today of a carpet and noticed a purple colour adhesive was used to secure the gripper to concrete floor. This stuff was bloody solid way better than gripfil I currently use. Been looking for hours online trying to locate purple colour adhesive anyone use this? Any links? Thanks

 

I’d like to know. Seen a good video the other day on tube adhesives ….

 

Stikatak super blue. Not seen it for ages.
We only use flexi fix now

 

Me too.
Flexi has never let me down.

 

Is that the one that used to come in a bottle? Or am I thinking of a different one

 

No it was in a mastic tube. PA5 use to come in a tub?

 

PA5, wow takes me back.....
Cups and lolly sticks
