This isn't a direct answer to your question, as it's a paint rather than
an additive, but, the all time, hands down best anti skid coating I have
ever seen was applied to the Open 60, OceanPlanet. It is called
Nautix-Grip. My memory is that it was imported from France (where Open
60s are a religion) by a company in Florida.

If you absolutely, positively want to keep your footing and stay
onboard, this would be the product.

Hi,

having to re-paint the deck of my 33 years old 33' steel boat, I have
a question to the DIY-and specially paint-gurus here. The old, well,
it's been three years since I built it from ground up, paint is still
good, but the anti-slip additive (by International) I stirred into it
(one bag per pint-can) does not do what it is supposed to.

It seems to be a plastic granulate that makes the paint somewhat dull,
but still slippery, especially when it is wet. And it seems to polish
off with every step you make on it. On my old boat, I stirred some
fine quartz sand into the deck paint (a polyurethan product), and that
lasted ages. It seems that one-component PU paints have vanished (at
least here in Germany) from the shelves, the present base on the deck
is an alkyd paint.

Now, apart from adding sand, has anybody here any trick to offer on
how to achieve a real anti-slip deck that earns its name? We rubbed
off the whole deck with Scotchbrite clamped into an electric sander,
using lots of water - works wonders. The surface is clean and dull
now. I intend to use the same paint I used before (Sikkens Alkyd).

But what to add to make it real safe?

Any advice? The negative factor o using sand is the long-term care
problem.

Thanks in advance!
