Non-slip adhesive?

[Pebbs]

The customer got him in so I ain't got a say in it really and still its thier money so well see if it was well spent or not?

I would have give it a go myself I have some experience and I defo would of used a primer too.
But I really need to develop my speed as I take my time with tiling and sometimes get worried customers may get annoyed with the time it takes me to complete the job.

Why are you bothered so much LB? the customer employed the tiler, and if the customer is unhappy, then they will take it up with the said tiler. Are you employed on the job to something else? Leave the tiler alone, everyone has to learn by their own mistakes.
