Paraphrased info from Dale plus what i did:
A product called “Vulkem 116”… a very grippy, resilient polyurethane caulking compound used in the home building industry. Applied directly to deck surface via caulking gun, squeege, etc. and may be textured with sponge, roller, brush, etc. Limited color range but may be tinted with dry pigments.

{Other suggested options: An acrylic marine fabric called “Sunbrella” which is applied with industrial contact cement (like “Formica” glue). Sunbrella won’t shrink or rot, comes in a wide range of colors and has a canvas-like feel.
Granulated rubber or “crumb rubber”… black carbon rubber slurry which can be obtained for cheap as a product of auto tire recycling, in various grits. It’s sprinkled over fresh tacky contact cement and then pressed down. When coarser granules (as 36 grit) are used, an additional, final coat of contact cement can be applied over the rubber grit to form a tougher, more aggressive nonskid.}
** Always use Vulkem 116 in an area with lots of ventilation.
** Do not store Vulkem 116 in refrigerator containing food or beverages.
** I prefer to work with clean, bare hands (very carefully) and wipe
up with small amounts of Tolulene on an auto detailing cloth. Or wear Nitrile gloves. Heck The Doc used kitchen sink gloves.
You’ll want to rinse area with fresh water and allow to dry
completely. Then wipe with Tolulene (the solvent I use). Vulkem 116
comes in a 10 oz. tube, so you’ll need a caulking gun. A small (3" or
4" wide) plastic bondo squeegee.
A roll of 1" wide 3M high adhesion tape no. 233:

I also used the same tape to tack the edges of the mat to a swept garage floor.
Put newspaper underlapping the areas where the Vulkem would slop over
Spread and work the polyurethane down into the existing surface with
squeegee for a good bond.
If you want to add texture, you can use a synthetic coarse nap roller
(I modify my own) used for drywall, sort of like this:

Or try dabbing texture with a clean (free from silicones, detergents,
etc.) coarse sponge. Tear off small pieces as needed:

I used a “stucco texturing” roller that had big stiff loops on it, sort of like the ‘closed’ half of velcro
Do not apply nonskid too thin or too thick. Depending on humidity,
cure rate is about 18 to 24 hours per 1/16" to 1/8" thick at 70 to 80
degrees. As long as the nonskid is outgassing (giving off a strong
odor), it’s still curing.
When finished, immediately remove any tape used for nonskid application.
Once you open the tube of Vulkem 116, and have used what you need…
seal tightly with several wraps of masking tape, put in zip lock bag
and store in refrigerator. Do not freeze.
Been a bit cool around here and it took a couple days to get the stink down and it still
(after a week) smells stronger than the original. Probably one of those things that will
cure for ever.
The whole job took me less than 1/2 an hour including clean up. Didn’t really have a big
enough bucket so I tossed the gloves and roller. Would have cleaned up easily w/ the tolulene though
but lack of planning so no big pan or bucket on hand. Couldn’t quite see my way to using one
of the wife’s baking pans…just the thought of the repercussions makes me pucker.
