I'm just an innocent bystander, but it would seem to me that laying down
redneck grass no matter how would simply invite a ton of moisture
between the wood and turf. Unless maybe you used felt roofing paper --
but to me, that would also seem to invite rot and mold from moisture,
humidity, etc and etc from beneath the deck.

Besides, ever see what happens to fake turf when you get a mess of dirt,
leaves, spilled food and drink, etc. on it over a few years? Ugh. Not
pretty.

Like someone else pointed out, if it's traction you want, add sand to
some sealer/paint. Or if you only need better traction in small areas,
there are stick-on thingamajigs that people most often use on wooden
stairs. Not pretty, but more attractive than redneck grass.

I'm curious as to what you mean by "rainproofing under the deck." What
exactly do you want to accomplish and why do you feel the need to do
this?

I know it's a total redneck solution but I want to rainproof under the
deck and improve traction on the shady mossy slippery surface on the
deck. There is no frost here... mild climate.

If I use 6 mil black plastic liner and a staple gun will that work? I
guess I'd tape the seams of the plastic liner but maybe it'd still drip
through the staple holes. Doesn't need to be perfect. Rubber liner
sounds expensive. Actually the nicer quality fake lawn at Lowes is
$4.46/SF & would cost $700 but maybe I can find a better price somewhere
or it's just a stupid idea I should forget.

Outdoor carpeting for boats is applied with double sided tape or glue
but that won't work with the liner below and would be a permanent mess.
Normal carpet is applied with those deadly looking spiky strips but I'm
not sure that works with this thinner fake lawn stuff. There is one spot
where it needs to be flush at the steps or run it all the way down the
steps too. That might encourage rot since the treads are all enclosed on
three sides.

This only needs to last 5-10 years and we'll remodel & tear down the
deck. Plastic "linoleum" doesn't sound suitable outdoors, too slippery?
