[Rosco100]

If your trying to prime tiles,Mix some tile adhesive with the primer and let it dry before tiling Works

Don't worry they will find something you did wrong

Was thinking this aswell to be honest.

I had the same problem with this s**t, beforehand I lightly grinded the tiles, washed and dried them, then applied primer, it took a long time to set and when it did it was a bit soft as you described ( came off when scratched hard) I took the chance and poured a Bostik deep leveling compound last job before Christmas.... first day back in January this is what greeted me, the primer came clean off the floor, I got in contact with bostik technical they came out looked at it and couldn’t give me a definite explanation as to what happened and told me to use bostik universal primer instead which after lifting the leveling compound I used and it worked ok.
They sent a new batch of special hardsurface primer to the tile shop, said it was ok to use so one of the lads that works for me had a nixer for his ant last week, tile on tile she got hardsurface primer from the same shop, he said had to lift a couple of tiles on Saturday and guess what... adhesive and primer came clean off the floor.
Avoid at all costs.

O rubbish. Tiles already laid ontop of leveler. Hope all is good with them and no lifting.
