Masking up for painting new anti-slip

[tudorsailor]

My "white" anti-slip is grey and worn. It needs repainting. I understand that one has to sand back to smooth and then paint on the anti-slip, maybe two coats.
What is the best way/machine for sanding? What paper should I use?
How do you mask up to get the nice neat curves that it currently has. Someone mentioned two types of masking tape, not just the blue. I assume that one sands before masking, and then masks before painting.

Please excuse these novice questions

Thanks

I just cleaned and painted my white "no slip" areas.

I just used 1 coat of International's non slip deck paint. When it started to look a bit worn I just repainted.

I think the International stuff, Interdeck ??, is still OK but I have seen reports that some brands, Blakes ??, are not in fact now very non slip. In fact a friend gave up after half painting his, I guess with Blakes.

Alternative of course is to paint, apply sand while wet, brush off excess when dry and apply a second thin coat.

Best advice though is to follow the paint manufacturers instructions . See the product data sheets on the websites. In fact quite a lengthy spec for preparing and priming weathered GRP according to the Interdeck Data sheet at http://www.yachtpaint.com/uk/ (3 coats of Interprotect, and undercoat before the topcoat) Mine were not old and weathered when I first painted them, only a few years old.


BTW use a very light colour or you will find that the decks get very hot in the sun.


Difficult to mask off round tight curves although you could cut the masking tape to match the curves.
Personally tend to cut in by hand rather than use tape.

Yes there are tapes that can be left on for longer periods. Not used them (obviously) but now readily available I think. Sure I have seen them in the DIY stores. Look at Screwfix website too.

Was in the chandler the other day and spotted some new 3M blue tape that felt
like plastic rather than paper. I assume this is to protect against sanding but I have't tried it yet myself.
I always mask before sanding and curves are handled by using a Stanley knife to
cut in.
Cheers,

You can make a curve by applying the masking tape then using a sharp knife to cur around a template, e.g. a tin lid and peeling away the excess.

There are several types of masking tape. The difference is in how long they can be left before they become hard to remove. The common beige is the shortest life - as little as 3 hours - while the blue is good for a day or two. Have a look on Screwfix.

You can paint straight on to old deck paint after a good scrub but to prevent build-up, sand back. You'll want to use 120 grit paper or coarser but take great care not to go beyond the edge of the paint as you'll permanently score the gelcoat.

There are lots of different types of deck paint. Some give a 'suede' effect. I find that is fine when wearing razor-cut deck shoes but lethal in trainers. Some use grit, either pre-mixed or added before applying. Blakes 'non-slip pearls' are a powder (aka Fillite) that doesn't give the sharp sandpaper effect that chews through clothing and skin. If you sprinkle silver sand into wet gloss, don't saturate the surface, you only need about 1 grain per sq cm so it still looks shiny!

Hi like you my deck is ok.However it is quite smooth in parts where the antislip is quite well worn. Q) is it ok to just buy some Int antislip paint and paint over it WITHOUT having to sand?

You can buy special masking tape that will bend edgewise around curves quite tightly. It looks a bit like crepe paper.

I might even have some in my garage and, if you're that interested , I could try and find it and tell you who makes it.

Yes please can you rummage in the garage and tell me who makes bendy tape

Thanks in advance

Go to an automotive paint supplier and get the narrowest tape they do. After getting the curve (it's very flexible) get a wider tape to provide more masking behind the curve (so you don't accidently dab over the narrow tape).

There's this on-line

Yes. I have a wooden boat and happily repaint the deck every three or four years - just give the deck a scrub and rinse off with fresh water. When it's dry slap on another coat. I use Interdeck and apply with a brush - stippling gives a better finish than brushing out (as it says on the tin ...)

Written inside is "Bought this from B & Q" but I don't know if it's their own brand or another.

Anyway, it's this sort of thing:-

I've repainted my decks twice. Didn't bother sanding or indeed any preparation beyond washing. International Interdeck. Used standard masking tape - it's easy enough to make it go round corners. First repainting started looking patchy here and there after fifteen years, second still looks fine after five.

Many thanks for the reply. I was hanging on for Vic? I will now go ahead.
