In the yachting community we use ground walnut shell on painted surfaces
to create a non-slip surface even when wet (with proper foot wear.)
More aggressive non skid can be made with silica sand. I have seen and
experienced rather course silica sand non-skid surfaces that would
definitely be something you wouldn't want to fall down on but of course
they offered excellent traction and reduced fall risk. Commercial
fishing boats (tuna clippers with helo pads on their pilot houses) were
the source of my silica sand experience.
With ground walnut shell or silica sand one successful procedure is to
paint the surface and while the paint is tacky spread the non-skid
material generously over it. When dry, sweep off all the loose material
and then give it another coat of paint. Another method of application I
have seen is to mix the non-skid material (walnut or silica sand) into
the second coat of paint and apply/spread it with a roller.
Not all sands are created equal. Child's "Play Sand" from the big box
store is inferior for non-skid. Silica sand has sharp edges which make
for a much better non-skid effect, even when coated with paint. Larger
course silica sand has terrific non-skid properties. Remember to wear
dust protection to avoid inhaling silica dust as once in your lungs it
is PERMANENT and silicosis is not something you want. After the silica
sand is painted and any non coated product is removed there is no
inhalation danger. It is the fine dust that causes a problem not the
grains of sand.

My shop has many coats of 2 part epoxy.
I needed to cut some wood on the table saw and didn't have a dust
collector yet, so I laid down several sheets of polyethylene. That
worked great, except... there was some very fine dust that made its
way past the sheets. I took one steep onto the painted floor. The only
time I ever went down that fast and hard, was forgetting to take the
guards off my ice skated. That hurt! At least I didn't break anything.
At the W end of the shop, the S side has an 8' garage door. I simply
rented a very heavy, orbital sander and used a coarse sand paper to do
a strip 8' wide from that door across the end of the shop. It worked
as well inside and left a better finish than using sand or an anti
slip compound.
The aprons for the garage and shop are painted with epoxy "with a lot
of sand mixed in!

You want to paint tower bases go to it. However, I beg you not to
paint concrete steps & walks. Unless you use the 'sand' paint or other
textured gripper paint. You can't imagine how slippery painted
concrete is when wet. As a retired postal carrier I know. Two of my
fellow carriers got their arms broken on painted concrete. If you
insist on painting steps & walks please add the wide stick- on grip
pads. The law suit you save might be yours. I lost a full uniform [
big $$$] because a teenager drained a car radiator down a sloping
concrete driveway. The homeowner bought me a new uniform & was
thrilled I didn't break any bones. Been there done that.
