I'm rebuilding a 13 step outdoor wooden staircase and entry porch on an
80 year old house. I bought some Benjamin Moore Deck and Patio paint for
the finish coat. It says on the can to use sand in the paint for a
non-skid finish. But it doesn't say anything about which grit of sand to
use and in which proportion. Can anyone shed any light on this for me?
The local real paint store (not big box) has the grit on hand. All you
need to do is say that you want anti skid and they pop the lid, add the
appropriate amount, close it and send it for a ride on the shaker mixer.
Having done this many times, I will tell you how I do it. Paint the
surface that you want to be non skid, then take course sand (such as
play sand or masonry sand) and broadcast it onto the painted surface. I
just take a coffee can with a plastic lid and cut some holes in the
plastic lid, then use it like a salt shaker. When you have a pretty
even coat, backroll the surface with a paint roller.
Works alot better than mixing it with the paint, where it all seems to
clump together and never mixes well.

Paint stores that sell silica sand for paint must have it wrong then?
I wouldn't find that surprising.
People want non-skid paint, they sell it.
If possible, I would use composite instead of wood.
No painting needed, never rots, it's non-skid to start with.
Only issue is composite needs more support since it
is not as rigid as wood.
