Sun Screen and Marking Paint

One thing I ran into was a guy from around the Great Lakes area ordering paint for the Mason Dixon Line area.

The paint used up there was lacking ‘sunscreen’ so it had poor ultraviolet protection. It was fine in winter or in summer if there was a week or more of cloudy days and rain . But during clear days in summer this paint usually faded out within 7 days, shorter than the required 10 business days life of the marks.


Trying to find a justification for buying more expensive paint I looked to see if I could find a UV chart for the various parts of the nation. I came up with nothing.

Does anybody have information on this and can share it?

I found a page that gives the UV forecast. If you dig deeper you might find a map that shows long term UV averages across the country.

If your company buys the wrong paint it is. Looks like your company has been buying the right paint. The paint that is resistant to UV fading costs more.
I did see one site where the marks were no more than 5 days old and everything exposed to the sun was almost faded out. Unless you looked close you would not see the marks. The contractor did not see the marks and cut a line.

Not in our neck of the woods, it is the contractor's responsibility to maintain the marks.

Generally speaking "maintain the marks" means to not disturb them. I believe in most jurisdictions the excavator is not allowed to lay down marking paint.

Yeah...maintaining here means to not willfully destroy the marks and to take every measure that is reasonable to preserve the marks until the expiration of the locate. Usually 10 days if contractor has not started working and 14 days if contractor has been working, all of course if the marks are still visable by then.
