what do you think I should paint GRP decks with that already have a non slip pattern moulded into it, similar to , say, the deck moulding of a Sadler? I do not want to use that 'orrible stuff full of sand, but would toplac or something render the non skid underneath no longer non skid..?
I have been pondering this for some time and have read the various paint manufacturers blurb about painting, but they do not touch on this, what I would reckon to be, common job.
There is no option but to paint the decks as there are various unsightly holes which have been filled and general severe ageing of the GRP by UV.

thanks.

using gloss paint alone will certainly make the deck slippier. you don't have to make the deck look like sandpaper when you add grit, a much lower concentration will do, as little as 1-3 grains per sq cm would work. this could be applied with a pepperpot while the paint is wet.

another option is to add a small quantity of 'Fillite' powder to the paint before applying. sold at great price by blakes as 'non-slip pearls' or very cheaply in bulk by grp suppliers.

I have used deck paint for twenty years now but without any of the additive. I don't find it necessary to add any of the grit and it gives me quite adequate grip. I have a wooden deck, glassed over and apply the deck paint direct to ordinary primer/undercoat. Although I think the text books used to say I should be using some clever self etching primer to get a bond, this has not been a problem and I see that this year's Blakes book talks of using their primer/undercoat direct onto abraded GRP. The deck paint is better in my view than doing something with a gloss + additive as it is self chalking - ie it wears away and therefore there is no build up when I paint it each year - would I need to paint it each year if I glossed+ it? probably because it does get wear and tear. I use Blake's which is designed as a non-slip product even without the additives but I guess International is the same. The Blake's book says that you can also use ordinary enamel and Polygloss but with additives. f you use Deck Paint, avoid a windy day if you can - despite being quite a thick paint to apply, it seems particularly prone to flying in the wind.

I hope this helps.

In the past I have painted a non-slip coating that had the roughness of emulsion paint, certainly not the highly abrasive finish of the heavily sanded paints. This is ideal for refurbishing moulded non-slip. Unfortunately I don't remember its name and the tin is long gone. It does exist, though, just keep looking!

Just painted my decks today, have the same nonslip decks that you mention,
Painted mine with Blakes Deckpaint without any additives, being using Blakes
for several years now, no complaints, does what it says.

Mike,
Blakes describe their 'Deckpaint'as a chlorinated rubber based coating, Is this easy to apply, and does it give a matt or shiny finish.?Will the original non slip pattern show through, as this paint sounds very thick. Did you use a brush or roller?

The finish is matt, my deck has had several coats now and the pattern still shows through,
but obviously it will cover it if you give it enough coats!
I use a brush, lots of cutting in on my boat! but see no reason why you could not use a roller,
It is possible to thin it down a bit if neccesary, Blakes No. 1 thinners if I remember correctly,
I used it as it came out of the tin.
find one coat is usually enough, It forms a chalky surface,
Personly I see no reason to add abrasive to it, It has a really good nonslip surface and the finish is quite good to look at, I have no trouble applying it, and find the coverage quite good.

hope this helps

most of Westerly Boats had non slip decks with deck paint. I repaineted my westerly with International Deck paint with a roller, Great finish. Latest boat had non slip patern which had been pinted with gloss paint. surface was lethal. Have now lightly sanded and finished with International Paint, again the finish was good

Painting decks memory jog

Jill could remember as usual, I never seem to store this kind of info. It's called, unremarkably enough, International Deck Paint. Your local chandler may well have a little leaflet with samples painted onto it. I see that John Corstophine also recommends this stuff. We were very pleased with it.

Glad to report " No senility yet"
Re Mlakes Deckpaint, checked the instructions on tin,
10% No 1 thinners for brush and roller.
30% No 3 for spraying.
No 1 still might be useless, but that is what is written on the tin!!!!!!!

regards mike
