a few month back i had a concrete base laid in ym garden for a garage that will be delivered next month. Today when I was in my garden i noticed a greenish colour on some of like the colour you get on slabs which have been laid after a while. It's not furry or anything but just a green tinge to it.
Should i just brush over it with soapy water to clear it off and is there anything i can put on top of base to seal it?
