A few weeks ago, we replaced the 40-year-old asphalt on our driveway
with pavers. Yesterday afternoon, when I came home, I noticed a large
stain that I am 99% positive was not there when I left in the morning.
The pavers are grey. The stain is an orangish-brown (more brown than
orange).
The stain is roughly the same shape as the shadow that would be cast
by the tree in the neighbor's yard if the sun were directly overhead.
The tree looks like a birch or beech tree.
It looks like something is dripping off that tree. Could it be sap? I
stood under it and didn't feel anything and I can see anything. The
stain is dry, not sticky. It's also very even, like it was painted
oon, not speckled, so if it dripped, it was something fine. PLus, I;m
pretty sure it happened in just a few hours.
Does anyone have any idea what this could be and, more importantly,
how to remove it?
We never saw anything like this on the old asphalt driveway, which was
also grey.
I can take a photo if that would help. Is there some good place to
upload it?
Any chance that the rest of the pavers that were not in the shade just
dried more thoroughly from the sun and what you are seeing is higher
moisture in the ones that were shaded? A paver that feels dry to the
touch can still have higher moisture content. And moisture content
definitely affects color. Try drying one with a heat gun or hair
dryer?

Ny thoughts exactly!!!

Mine too. I redid a little walkway with some square patio block and
crushed marble stone. I got rid of the stone and made it all block, I
had extra blocks from another location. After a rain half of the block
was dark and half was light. I redid the walkway again so when it's
somewhere between wet and dry, it looks like a checkerboard. When it's
all dry you would never notice a difference in the blocks.
