I got my driveway Tarmac'd last March or so, I do a fair bit of car cleaning on it and its starting to go a bit white, I do rinse it after every use, but I could literally stand for 20 minutes in one spot with the power washer, holding it at that one spot and the foam from the detergent just keeps coming up from between the stones.... How do I stop this getting worse?
would you be able to rent the sort of machine used to clean pavements? Im sure it would be a bit more industrial than the power washer?? After cleaning it seal it somehow... :/
Sounds like a plan, I will get in touch with the guy that laid it initially to get it sealed, although it seems even sealer isnt bulletproof either!
the possibility of power hosing your driveway probably doesnt help though.. same thing as power hosing paved driveways, it power washes the grouting etc out, and if not re-grouted weeds etc appear...
