Hi,

I have a path made of (what I'm guessing is) keystone slats that goes
from the sidewalk to my house door. When it rains the stones become
*very* slick.

Is that the property of all stones or are some stones more slippery than
others? I'd like to stick with natural stone if possible.

Thanks,

Aaron

The walk way / patio stones I've used are referred to as Arizona
Flagstone.
The material is some what rough and not slippery when wet when the
light tan / beige stones are used; grey or blue / green / grey stones
tend to be less rough and more prone to being slippery.

As Ransley mentions, any kind of slime / mold growth can be VERY
slippery.
Also drainage water can carry soil "fines" onto the stone & leave it
covered with a thin layer of slippery mud.

cheers
Bob
