Just as a point of interest: that area where he's standing is just outside the top door to my shed, and was a pain it the butt for quite some time.
When the plumbers put the sewerage line in they didn't bury it to optimum depth, and it's barely an inch below the surface across there; way too shallow for me to lay concrete over it.
So that area is all crusher fines and pea metal.
We lived in the flat immediately through and above the door behind the dog while we built the new house, and I would walk small stones inside on my boots . . . which would upset She Who Must Be Obeyed greatly.
So I painted it.
All the scrag ends of paint we accumulate over the years with an inch in the bottom . . . not enough to be of any use, but too much to throw away got utilised there.
That paint would now be about an 1/8"th of an inch thick.
And it works!
No more small stones tramped inside!
It might not look too flash at the moment; but one day it will become a uniform colour . . .
