I wonder if anyone has used a simple wood stain to stain their concrete? I accidentally spilled some of my fence stain onto my pool deck and it looked beautiful. I tried to clean up the spill with an acid wash and then a power wash and had no luck. So, I am thinking that it is at least durable! I know there are products on the market designed for this application but I tell ya what... I didn't have to do any prep and it looks great. So, unless somebody can tell me that this will come back to haunt me...I think I might have just had a Happy Accident.
