Adhesive showing through tiles? - Tile Advice

[Jasonnnn]

Attaching pictures… any advice? Is this the adhesive or a defeat in the tile? 8mm porcelain tile. Bostik A150 super grip adhesive. Tiler is more than experienced and not spot technique was used from watching him at work. Thank you.

Wrong adhesive has been used on that size tile . The reason for the adhesive showing definitely looks like a spot method hence the shape of the wetting.

wetting.

Ok, thank you. What adhesive would you recommend?

Needs to be a cement based bagged adhesive, dispersion adhesive won’t dry on that size tile.
