Ive been asked to rake out a 15 m2,porcelain floor,grouted in bal super flex. Its been done to a bad standard as the joints are very low and have got very dirty.I just wondered what peoples thoughts were on the best way of doing this? Manualy with a grout rake or invest in a fein multi tool?? The tile are 800x800. Any feed back would be great.
Thank you.
