Sailhog...looking at your specs...I see you sail a Catalina 30. If it is old and pretty beat up and you are trying to inexpensively dress her up a bit...then a one part poly is appropriate. If she is newer...it would be a mistake.
Unlike the advice I gave above on the Passport 40 hull... you CAN roll and tip 2 part on deck 'cause high gloss is not as critical and you'll have a lot of non-skid areas. It will last WAY longer as well if the expense is not too great for you.

A rolled/brushed deck paint job will forever look like a rolled/brushed paint job. It will also seriously harm resale value and the potential sale itself. The only way to get a finish that looks as good as the original is to spray and have it done properly.

Painting topsides is easier, less stuff in the way and besides, you rarely see the topsides when you're on board. An unsatisfactory deck paint job will bug you every day you're on board, it's never out of sight.

As indicated above already, the prep for deck work is much more, including removing as much hardware as you can and masking and painting the nonskid areas after the first layer is on.... it's a huge job.

She is an older Catalina, but not too beat up... I might have to make another trip to WM. Thanks again for the advice, Cam...

Material costs?

Can anyone give me an approximate cost per gallon and coverage rate for both 1 part and 2 part deck/topside paints?

And when you say 1 part will not last as long as 2 part, are we talking 2 - 4 years vs 5 - 10 or 5 - 10 vs 10 - 20? Will additional coats of 1 part build it up to rival 2 part for durability?

Thanks,

John

I painted our deck about 8 years ago with 2-part poly; roller & brush with a flat finish. It is starting to wear now, and needs new topcoats. We tested 1-part before I began. It lasted about a week on the foredeck section we applied it to: totally worthless on a deck that gets stepped on, and essentially the same prep. 2-part is a no-brainer.

Cost and coverage?

Thanks, Paulk. Do you recall, or know, the approximate cost per gallon, and how far a gallon goes? I have a Catalina 27 that needs a total hull, deck, and cabin job.

And anyone with tips on spraying, please post. I have a spray rig (and I know how to use it) and I need to know about how thick or thin this paint is, how easily it sags, drying time, etc.

Thansk,

John (making a silk purse from a sows ear - hmmm, maybe a good name for the boat....Silk Purse)

While it doesn't give price, everything else you need is at this link. It's the Interlux data pdf for Perfection, one of the top 2 part polyurethane paints. Their site gives the info for applying all their products.

Good link!

Thanks for the info.

Now, the durability question:

I have (1 part) polyurethane on my floors and it lasts 5 - 10 years with minimal upkeep. Why does (1 part) deck poly only last a couple of seasons? Or does it really last longer than that?

Thanks!

John

Restore the Gelcoat instead?

Tips For A Great Buff / Wax (Long) - Cruisers & Sailing Forums

This guy is worth reading. He also has a great blog about upkeep and boat improvments.

He swears too many boats are painted when they have a gel coat that can be restored with the right tools and people. If you are considering paint, it will be worth your time to read up on his stuff.

there is no money involved here, just a generous boat guy it looks like.

He has other posts over there, just do a search for his name.
His blog and plenty of killer pics here:

You're right - Maine sail is awesome. His pbase tutorials (which he does for free because he enjoys it) are linked throughout Sailnet and used often as well as linked by many including myself on the 7 or 8 groups and websites I belong to.

Where are your floors? Are they in the salt and sun 24/7? Our decks are and suffer more than any floor I have seen. The marine environment is a tough one for finish products. Remember the prep and labor to paint is close to the same with cheap enamel as with the best 2 part poly. The longer it survives the better for us. One part poly is good but not as durable as a good 2 part poly. This is backed up by many who have used them. Based on what I have heard from several boatowners 3 -4 years is a good run for 1 part like Interlux Brightside. A good 2 part like Interlux Perfection or similar lasts twice as long based on what users say.
