tiling over quarry tiles

aye in my bathroom, there could be anything on there

 

Anything you need to admit to the group about?

Blood?
Poo?
Semen?

Please explain!

 

I thought there was a special adhesive specifically for tiling on top of quarry tiles

 

Yup its called spit!

 

Lads I'm finally getting round to doing this job, any more thoughts?

 

make sure you do a tight coat

 

It's bound to have been waxed in the past so ignore all these professionals. Degrease it, then finally get your hole into gear?
