Cockpit and Deck Painting Advice
Considering refreshing the wearing paint but could use some advice. Probably can't paint until spring given the weather but figure I can do some prep in the cold. Also need to keep the boat near working since we go back in the water early (April), so can't just remove all equipment. I need to rebed a few items so will be removing some equipment anyway.

Deck and cockpit have mix of glossy and nonskid.

What is the prep process?

Are people happy with Interdeck?

Is taping sufficient for equipment that will not be removed?

I'd be interested in this as well, planning to redo my cockpit and deck this spring

I have been using Interdeck for some years. Easy to paint, works fine but
- fades in the sun, re-painting is needed after some years if one want the original color.
- soft so wears down

Also, at least in my area, Interdeck is no longer available in all colors, in particular not in the one I first used, which I still prefer.

Two component paint is usually stronger, but also much more difficult to apply. Awlgrip is often mentioned is giving good results, both glossy and non-skid, but I do not have any experience of it.

On balance, I am rather satisfied with Interdeck.

Preparation: sanding!

Good luck!

Also satisfied with Interdeck, esp the 'grip', but it does tend to 'hold onto' dirt. Easy to apply - yes it changes colour with time but in our case now closely matches the rest of our deck (was much whiter to start with but has 'yellowed nicely' ;)) Pretty sure that Interdeck is just 'Brightsides' with grit so you should be able to blend some colours for a few more options...

Think you can mask around equipment that you can't/don't remove, but better to get under it if you can. On a past project we removed everything but the toerails and winches, taped off around those.

If you have a molded nonskid pattern it can be difficult to properly prepare.. if you don't want to preserve it I guess you could sand/grind it smooth and start over. Otherwise the best prep you can do might be a thorough TSP scrub followed by a solvent wash. If you do use Interdeck it will likely 'hide' the original pattern.

Many here rave about the results using Kiwi Grip, and I've seen some nice results too - it's also tintable to your colour so before committing to Interdeck maybe check that out first.

Non 'nonskid' areas should be sanded properly, cleaned and then probably 'rolled and tipped' unless you're able to spray. You can get a reasonable DIY result with the HVLP blower/spraygun setup that bathtub refinishers use.

I can endorse either one or two part Petit paints for doing the whole topside area. While one part (EZPoxy) is maybe 40% cheaper, I can't really say that the two part (EZPoxy2) is really any harder to work with and is considerably more impact and abrasion resistant.

While sanding before the first coat and between coats 2 or even 3 is very important, it is critical that, before you do any sanding, you thoroughly wipe down the entire area with a prep coat which will remove any and all traces of grease and (most importantly) residual wax and polish. If you don't do this, there will be adhesion problems.

Modern epoxy paints are very easy to work with and give great coverage and gloss. If you are going to use a different color or additive grit for the non-skid areas, do the gloss areas first (2 or 3 coats) and then tape off on the cured gloss area to do the non-skid.

If you are using the same color and not using a grit, you will only need to tape anything that can easily be removed. This gives you an easy justification for rebedding all of your deck hardware that is removed for painting easy with butyl tape.

Re: Cockpit and Deck Painting Advice

What would suffice as a prep coat pre sanding?

Re: Cockpit and Deck Painting Advice
I have always used DuPont PrepSol

There are probably lots of products like this from all paint manufacturer's, but I would use those solvents that are specifically designed for this kind of cleaning and surface preparation.

One can will last for quite a few paint jobs.

Re: Cockpit and Deck Painting Advice
I used the 2 part interlux Perfection and was really pleased with the results and didn't find it all that hard to apply. I never painted a boat before, so was the first time doing the roll and tip method. obviously, prep is the most important part. I took the time and filled in all the gouges with Pettet 2 part marine filler and sanded smooth. Sanding is the key after filling. Run your fingers over the patch with your eyes closed. If you feel a bump, need more sanding, or else is shows in the finished product.

A couple of tips on the roll and tip method. I used standard foam rollers from Home Depot. Key was using a Badger hair paint brush. Need to keep in clean and wet. Keep all the paint off of it. Dip the brush into thinner and then shake out well before tipping. That way the brush glides over the paint very smoothly.

Don't get in a hurry and don't set a deadline. Do what you can do and then do more the next day (or weekend). When you start hurrying, is when it get sloppy.

Take a look at this guy's site; he has very detailed notes on what he did and what worked.

Re: Cockpit and Deck Painting Advice
Will look better, and keep water out better, if you remove the deck hardware. However, if it is bedded well, and taped carefully, I have seen this look pretty good. You could just sand enough to get good adhesion, IF, the underlying paint is not peeling or flaking.
