I used Weber grey grout and Weber grey Silicon. I used a profiling tool to tool the Silicon. I then noticed that the grout would not dry on the horizontal grout line within the shower. Obviously I have smeared a thin layer of Silicon across the grout and it has gone a bit shiny!
I don't know if this will dry out, but it has messed up my job and i'm not happy. I've been paid, but have told the customer that if its like that tomorrow I will come back and sort it out.
I did not want to muck around with the Silicon whilst it was still wet.
Has this happened to anyone?
