Optimal anti-slip paint?

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!

Sugar makes a great non-slip but the little craters are the devil to keep
clean.

Not mixing. Sprinkling.

And the sugar in deeper layers acts hygroscopic, i.e., it attracts
water. Not exactly what is intended.

But thanks anyway.

The way you use sugar (or salt for that matter) is to sprinkle it on evenly
with a flour sifter while the paint is still wet. Then after the paint is
cured wash it off and the crystals dissolve out.leaving a nice uniform
finely pitted surface. The only real problem is that the pits are the shape
of the crystals, often straight sided which collects dirt and is hard to
brush out completely.

Thanks for the enlighting, anyway. People who have done that here
complain of the dirt collecting in the little craters. My berth is
just opposite the locks of the Kiel Canal, which means lots of smoke
and other residues of the crude oil that the big ships push out. That
combined with the odd rain shower lets the surface age pretty quickly,
optically at least.

But the method is nice.

AFAICR a possible way to get round that is to paint a second coat of
paint over the craters.

Wouldn't take too long to try out a sample on some scrap board, to see
how easy it is to hose/scrub clean.

The first coat of paint could be done through a template or with
masking so the edges are left clear and so easier to clean.

cheers,
Pete.

I've heard of some folks using Epsom salts as well ...same effect.

Glenn, or anybody,

Know of any anti-skid treatment that a) works well, and b) does NOT turn
into a dirt and grime collector? I need to decide what to do on my aft deck
and the sheer decks (see http://www.glacierboats.com/tongass ). I'm not
worried about cost if it's the right product...

Thanks,
Brian

Since the way a non-skid works is by providing a myriad of tiny edges,
and those tiny edges collect and harbor dirt, it seems that to get
effective non-skid, you have to live with dirt. It should be possible
to balance these to some extent...

I have seen a non-skid surface created out of spray-on pickup truck bed
liner with rubber granules embedded. Personally, I think it makes a
great deck surface for a work boat, but it is a little "coarse" as well
as coarse for a pleasure boat.

Yes. This year I have chosen to piant my bottom with hairy green antifoul
paint. I've had trouble however, exactly matching the seagull patina on the
cabin roof - any suggestions?

Why bother, that stuff is waterproof, doesn't fade, non-slip (after
the first few hours) and is very environmentally friendly being made
of totally recycled products

Bumps are easier to keep clean than pits so sand or ground rubber additives
are popular but the paint wears off the tops of the bumps faster.

Somewhere around here I have some samples of a really professional system
for applying non-skid patterns. It comes in heavy vinyl sheets in positive
and negative versions in just about every pattern used on production boats.
The positive is applied to plugs to form the pattern on the mold and the
negative is used to apply a gel coat pattern to a finished deck. The result
is really professional looking but takes a lot of work and isn't cheap. It
is reusable though so with a little planning you can apply a fairly large
area with one sheet.

Maybe.... I'd have thought that the slippiness is down to aquaplaning
more than anything.

Just had a thought that maybe sprinkling small crumbs of foam (same
colour) on the wet paint, then overpainting with a generous coat would
give a nice rough surface.

The obvious answer is to choose the colour of the paint carefully
to match that of the expected dirt.

True, doing the areas of anti-skid in black would help, though not in
hot weather!

cheers,
Pete.

Maybe, but I've heard of some rubber-like compounds that get grippier (is
that a word?) when they are wet, especially if wearing rubber soled shoes.
There must be some kind of coating that's relatively smooth while still
being appropriately grippy. OR, at least be grippy but not hard to clean.
Still thinking ...and looking.

And I would think that the anti-skid treatment of a deck inside the boat has
lower requirements than the sheer deck (especially mine since I'll have no
hand rails on the boat). Sand (or similar) in paint or epoxy works well,
but my son's boat attests to the fact that it is wonderful for collecting
dirt and growing 'things'. We wash it out in the Spring with Clorox
solution and if it's still ugly, then we put another coat of Behr brand
porch paint on it.... A coat of paint is good for 3 years max.

Bought some stuff that's used for wing walks awhile back ...spendy,
especially once you consider the hazardous material shipping charges that I
got caught with. I think I'm going to test a few different methods on some
spare epoxy-coated plywood and see what I like, which is easiest to clean,
etcetera. No hurry.

A slightly different approach: Mask the areas where non-skid is not
desired. These areas will provide good drainage. Apply a light coat of
paint and while still tacky, sift or sprinkle silicon carbide granules over
the painted areas. When dry, remove the masking tape and paint over
everything. Surprisingly, the paint doesn't wear off the granules very
rapidly.
