Re: Paint gelcoat

Epoxy alone, even if coloured, won't hold up against UV. You have to paint over it, otherwise it will yellow in the sun.

I understand there are 'low blush' .. are there really 'no blush' epoxies?

Re: Paint gelcoat

Yes, trying to apply gel w/a roller or brush *would* be a PITA and look like poop. Understood that gel gets it's "face" from the master mould. I saw a vid w/some guy spraying gel; some as the master plug w/some sorta exrta hard molding gel, and some "regular" during molding process...so it's possible. Doesn't gel have the UV inhibitors??

Re: Paint gelcoat

Gelcoat does have UV inhibitors added. There are some that can and do respray gelcoat. However, that will either be prohibitively expensive to get a pro to do an entire deck, or very likely to be a DIY disaster.

Re: Paint gelcoat

Just out of curiousity, I'm assuming you mean the shiny parts - the non-skid areas would/will be coated with something else.
That being the case, look at the soft deck or cool deck EPA foam stick ons, they work good and feel great.

Lessons learned are opportunities earned.

Re: Paint gelcoat

Makes me wonder about other, industrial epoxies as deck coatings?? There's some used on guns that are seriously effective at repelling scratches and common wear. These started out as specific industrial equipment finishes; so I'd think that they'd have *some* application??

Re: Paint gelcoat

The BIG BIG BIG BIG issue and it is a BIG issue is taping pulling and re-taping between coats

Its a large amount of work when doing the topsides and you can reach everything its a whole another can of worms when you do the final Awlgrip coats as you have a fairly short window to pull the tape or you will lift of tear the edges

The 545 primer is really friendly to work with the topcoat is a science project of matching temperature and humidity when your working outdoors AND bugs like it a LOT



Your going to go from this



To this which this and absurd amount of 545 primer at which point you will be thinking painting is pretty easy







Once you hit this point its humble pie time as suddenly you now have tiny UNFORGIVING WINDOWS and a paint that gets angry because it 3 degrees colder that it was the day before or you should have put in one more ounce of reducer


I will stick with interdeck or kiwigrip as there durable enough and you can really screwup and get a good result

Re: Paint gelcoat

I ask the question again...with non-skid making up MOST of a deck (at least on my Edel) why not just do the whole deck in non-skid? On my boat it would be impossible to sun yourself in your Speedo or less without having most of your body lying on non-skid. What is the practical purpose of the smooth lines between the non-skid other than they stay cleaner?

I believe you are correct.

I just meant that it is compatible with epoxy. IE you can awlgrip over epoxy.

I've seen it done. I personally don't like the look especially on vertical surfaces of the cabin.
