Do i need to remove wallpaper paste?

[richiep]

Hi all,

Tiling a kitchen splashback soon, only 5 sqm, using small ceramics. Customer has half the wall already tiled, and remaining half was wallpaper. The wallpaper has been removed but i'm worried about there being some wallpaper paste still there which may affect the bonding of my adhesive. I will be using bal blue star for this.

Is it ok to tile over or should i be preparing the wall somehow? If so, what should i do?

Thanks, Rich

Best to remove as much of the paste as you can ,Whats the wall substrate
