I'm nearing the end of the refurbishment of my FRP NSM2 (3285) and am on the point of painting the inside. What paint should I use? I like International Paints but can only think that the best thing to do would be to add their non-slip additive to their normal paint. The boat already has a non-slip finish moulded into it (looks like someone covered sections of it in sand!) Or perhaps I should I use deck paint? Any help (and any sources) would be most welcome.

Best stuff is highbuild which you mix with colloidal sillica to give the non slip you see in the winder placcy boats.

Very hard wearing but not cheap!!

A cheaper alternative is to pop to your friendly car piant shop, choose your colour and get them to matt it down for you.

Hi Richard

Depends what you mean by painting the inside? If you are about to paint the whole of the inside then I have used  a 2 pack paint from a firm called serene Paints in Burgess HillWest Sussex. The paint is called 65 Weathersafe Colour Light Grey RAL 7035. To create a non slip with this thin some of the paint down brush on area you want non slip sprinkle some Budgie sand over through a sieve (cant spell)let it set and paint over again with thinned down paint.

If the boat is already painted inside then just check if single or 2 pack. If paint is quite old then going over it in 2 pack should not be a problem just remeber loads of preperation!!!!!

whats wrong with International Interdeck ? all the major chandellers sell it. about £16 for 750ml

it's not very non-slip and it don't last very long.

I have just done this on 1728 having spent last summer as though I was practising for the winter Olympics (speed skating a speciality).  Having an all varnished boat I first mixed the International non slip additive and was not too impressed so have gone the sieved budgie sand route and the result is so much better. I think I remember a thread some time ago which said that salcombe sand was the stuff to use!   (Do you think I should get a mirror, bell, ladder and a chunk of cuttlefish?)

Richard,

Be careful that the paint you use does not add a lot of weight. I was very suprised at how heavy a tin of deck paint was. When I used it a few years ago on a plastic boat I just masked out some small areas.

Can't you use sugar as well as sand?!

I have been told that sugar can be used.  You sprinkle it on and let it dry then you have to flush the sugar away and it is supposed to leave a rough surface.  My main concern would be that you need to make sure that the sugar is completely flushed away or it is possible that mould might grow.  However if you capsize a lot like me then flushing it away won't be a problem for long.  Like Dave I masked off areas too and did it in strips.

We still do the folowing use a plain very open net curtain material and apply it to the wet varninsh it goes transparent leaving discrete but efficient high spots then another coat of varnish and Robert id you fathers brother. One need onlu use 1-2" strips about that apart.

AG strikes again - good idea

For a real trouser ripper non slip use sawdust instead of sand and varnish/ paint over the top of the strips VERY effective as non slip.

Epifanes do a matting agent that will change a gloss to a matt finish which looks a lot better inside the boat.
Presumably if you use sugar it needs sprinkling on AFTER the paint/epoxy is applied so that the grains can then be flushed out?

Either sugar or salt sprinkle after you have applied the paint or varnish leaves a very grippy/aggresive finish. With sugar make sure you wash it very throughly else you'll get all the flies on it in the summer!

is there a low-cal alternative to sugar?

Both Awlgrip & International market non-slip granules to add to gloss, seive or premix. Likewise
Internatinal/Awlgrip/epifanes all have matting agents to take the gloss away. You will have to go to a paint specialist to get them, if you don,t know of one contact them direct for advice on local supplier which will be quicker than heresay.
I'am sure all the other major paint companies do likewise. Best of luck Barry.

The sugar solution turned into a godawful mess when I tried it, but the sea wahed it off in a week or three.
