I kust bot a stilt house that has like an area for a car underneath, only I won't be using it for anything but gardening. Anyway, it is painted pink, need I say more. Do I have to get that paint off before I can do something better? I saw on TV a product that is like little pebbles which sounds nice & natural looking. Since it's a rather non-essential area I don't want to spend a fortune if I can help it but would like it to look more natural. Any suggestions would be most appreciated. Thank you!
