Hi all i did job last year it was about 100 metres of 600x600 porcelain from porcelanosa in a house which was open plan and big rooms the customer wanted light grout which I tried to warn him could discolour so he bought maple kerpoxygrout and paid over £200 for it. I know the client very well as I do a lot work for him and he has been asking me to come round to look at the grout because it's discolouring, so when I went round tonight the grout is just dirty more dirty than I would of expected for epoxy as I only did the job 7months ago. They are very clean living people shoes off at the door ect. And she steam mops it every day. I have got a couple of bottles of grimex to try on it, does anyone know of a stronger one they could recommend to try on it? Has anyone else had any issues ? Does anyone more a number for the mapei reps I could speak too
thanks for your help
