But if you sprinkled the sand over applied wet primer, let dry, and

good nonskid surface. *Am I missing anything?

In several floors I have done with epoxy over concrete, only one with
a very fine anti-skid additive was successful. My latest (Sears epoxy
kit) was furnished with the usual fine sand and is a total mess just
like earlier ones. In any traffic area the sand scuffs off regardless
of the number of epoxy layers, and the resultant little craters are
dirt traps that are totally unacceptable. Even when the area is
untouched by traffic, the sand grains make sweeping an aggravation.
Haven't researched anti-skids yet, but I suspect the people that have
boat decks have some good stuff to solve the problem of what works
best on a wood ramp.
