Dusty tiles?

Also did you prime the substrate? Sorry welcome.

:welcome:to the forum

i would tend to think of dusty substrate or tiles,what kind of adhesive and trowel depth have you used,did you press the tiles down or back skim them?

simple questions but one may give us an answer

 

[Spud]

was the slate green in colour by any chance ?

 

[doug boardley]

was there any bow in the slate therefore not achieving 100% contact?

But did the adhesive stick to the concrete substrate?
