Flagstone Patio -- Disaster or will it be OK?
We just had a flagstone (Tennessee fieldstone patio "finished" yesterday... it was a joint effort between our landscaper, his help & my husband..so semi diy. They dug out the sod, laid it on that gray sand mix stuff (sorry not sure what it is), placed the stones, then the guys swept Quikrete Sand topping mix over the whole surface, into the gaps. Guess what?? Now they are not the nice variety of colors anymore, they are all GREY/BROWN. My husband did not see the end result on the day until too late but I was assured we should leave it and let it set between the stones and that it would just wash off the stone surface easily. I was skeptical and it turns out, is not really the case. I think after researching a bit, that they should have actually used Power-Loc jointing sand, as they seemed to be using it in the same way as that describes. Needless to say it has turned out to be the blind leading the blind here & trying to do it on the cheap...! (except for the stones...). Our Landscaper (who has not yet been paid!)is bringing back "concrete cleaner" Monday -- does anyone have suggestions? Can you speak from experience & did yours recover?
It did seem to scrub off on spot test with water & stiff brush but not sure it will be the same as it was. This is really annoying when we purposely went with stone to get a nice naturally-varied look! Help?
