Non slip.

[single]

Today is non slip deck painting so i'm rubbing some areas right back to the gelcoat.Question is, do i just bang on a few coats of deck paint or should i use primer first?

I have never used primer for this, but it might take a couple of coats to get a good solid colour.

I'm not trying to be funny but why not do what it says on the can?

Presumably the manufacturers know what's best and anyway, if something goes wrong, and you haven't followed their recommendations, they won't be able to help you.

When I added nonslip (Interdeck) to the cockpit sole in my Westerly, I used a GRP etch primer first. I don't know whether it was necessary, but nary a flake came off the nonslip in 20+ years.

For what it's worth, we gave up using Non Slip paint several years ago, It's almost impossible to keep clean and looks tired after a single season.

Have a look at some of the Industrial Grade stick on non slip strips, takes minutes to apply, lasts a lot longer than any paint and is designed for outside use and has good chemical resistance.

Good luck and fair winds.

This implies that there is an existing coat of some type of paint. It's only necessary to sand this down enough to provide a sound substrate for the new paint. There's no need to remove it completely, otherwise you will need to use a primer, of the type suggested on the tin, as Parsifal says.

I was surprised to hear the opinion that paint looks tired after one season. When I bought Mojo, she was near twenty years old and has patches of non=slip paint, pattern similar to the way yuo'd apply Treadmaster. First winter in the yard, we used patio cleaner in a pressure washer (low flow to apply the detergent), let it soak for half an hour (cup of tea) and then went over it with the patio cleaning head - one of those swirling bars in a box. Everything came up nicely, presumably greatly helped by the fact that the jets hit form every angle.

Now she's getting on for thirty, I'm considering masking up for a fresh top coat to make good the slightly nibbled looking edges.
