Question about Deck Painting Procedure for 2 part paint???
 
The deck of my luders 33' badly needs refinishing. I am undecided what paint to use. I have tried interlux polyurethane on the interior and I don't think it is hard enough to hold up on the exterior. I am hesitant to spend the big bucks on two part epoxy paints since I have no experience using them, but I think it is what I will do. I will have to do the job peice meal since I can't have my entire deck looking like a mess for an extended period of time. Can I sand and prep one area, prime it and then finish it with awlgrip and expect to get good results when I have to do the adjoining sections later? Should I take my hand rails off and port windows out?
I know it is going to be a big job so I might have to wait... in the mean time would it be a bad idea to touch up the deck with a cheaper one part paint or will I have to sand it all off later when I am ready to do the whole job with something like awlgrip?

Thanks...
Bret

You're right here - it isn't.

Good - you get what you pay for and if you do it properly you will not have to do it again for a long time.

Probably not.

Yes - and take everything else off the boat too.

It is indeed a big job.

You will have to sand it off.

Think serously about hiring someone to do this for you. If you make a mess, your boat is going to go down in value quite a bit.

Don't use Durabak...it's like painting with puke!

What about removing a teak toe rail? About half of the bolts fastening my deck to hull joint are also used to hold the toe rail on. The toe rail is in good condition and there are no major gaps between it and the deck. I am worried that removing it for an extended period of time would cause it to warp or straighten out.

Removing as much hardware as possible will be a key factor in the longevity of your paint job. Hardware left in place, including the toe rail, is where the breakdown of your coating will start; on the edges. If you use a two part paint the hardware will also be an impediment to doing the job as the paint dries extremely quickly, leaving little time for 'cutting in' deck fittings. This is one of the reasons that some elect to use a single part paint, accepting it's shorter lifespan.

I would not be concerned with warping of the toe rail, unless you're the type to start a project and then forget about it for a year or so.

I would approach the project as a major one, allowing time for removal and rebedding of all deck hardware. While you do not state the age of your boat, all boats will need their hardware rebedded at some point in time. There can be no better time for a thoroughly done job of this than prior to the painting of the deck.

In the meantime, I would avoid any quick fix paint jobs designed to improve the appearance of your deck. Many's the restorer who has lamented the fact that, had nothing half-way been done previously, the job of re-finishing would have been much easier. Sail the boat as is until you are ready to do the job right. Bear in mind that most are envious that you are sailing while they do not even own a boat, much less even a project boat. It is quite amazing how little deck appearance effects sailing performance.(g) You'll have enough off water time when you decide to do the job to not want to extend the project longer than necessary.

REMOVING THE TOERAIL CAN BE DANGEROUS.

Removing the toerail can lead to warpage of the hull-to-deck join and can make it impossible to get the toerail back on. It depends on the type of joint, but most things I have read recommend removing and replacing the toerail in sections. At the boatyard where I winter over, the pro painter does Awlgrip deck and hulls all the time and he never removes the toerail even though all other deck hardware including ports comes off. Yes, edges are where the problems start, but you have to draw the line somewhere, and the toerail is an excellent place to do it. Also, you can indeed do the deck in parts. In fact, you will mostly have to, in order to maintain a single wet edge. But even if you let the paint kick between areas, if you choose your lines to coincide with the lines made by non-skid patches you can blend sections together. I recommend getting one of Don Casey's books, which have very thorough and specific directions (and important precautions) for achieving professional looking results with two-part paints. There are many things you need to know to make a two part paint job look good. Fortunately, people have figured it out and written the book for you.

Dear Bret,
I painted my entire boat, deck, non-skid, freeboard and below waterline. I removed all hardware and teak. I used one-part polyurethane and the roll and tip method, as recommended by Don Casey. (I studied his books for months before.) I buffed with rubbing compound before waxing. The results, while not professional, are beautiful. Everyone comments on it. If I had it to do over, I would have used 2 part paint for the durability, as my paint is starting to chip a little bit after two years on the water. However, the touch-ups are quite simple with one-part, so I'm not too disappointed.

Don't start the job until you have the time to complete it. Doing it in parts will not produce nice results. You need to keep a wet edge. You need two people who are willing to work for beer (AFTER the job is done) ..

For our project please go to youtube.com and enter: Abigail Susan.

Interlux Perfection (formerly Interthane Plus) is very easy to use for a DIY application as it is designed for roll/tip or spray. My deck/coackroof was sprayed with Interthane Plus 5 yrs ago and has held up well. If just doing part then think about the non skid areas. Much like flat paint vs gloss is very forgiving. You can then tape off that section and do the rest later.

I have been old Awlgrip is very difficult to touch up but have had no experience with that. OTOH I have used Interlux one part Brightsides to touch up any areas where I do repairs on my deck with outstanding results. Also you can choose the same colour in Brightsides and Perfection (I use Off-White).

The one part levels better but the two part lasts longer. I would use 2 part. Around the toerail you could probably put the paint right up to toerail and then apply a bead of 4200 or something to cover the edge of the paint - much like 1/4 round when laying flooring at home or silicon around a tub edge when laying linoleum in a bathroom. Everything else should be removed.

As for one part now - two part later. Is not a problem if you do the prep work properly. Interlux two part primer is designed to protect "unknown" paint from the harsh two part paint being applied over top. As our boat had a failing unknown paint on the deck I sanded, sanded and sanded some more and then primer coat and two part paint. Have experienced no problems in 5 years.

The painting is the easy part - it is the fixture removal and prep work that takes the time. Also - when removing windows you will discover the joys of butyl rubber. When people tells you it does not harden they are correct. It also gets into everything and you spend half your day getting trace amounts off the deck that you wish to paint!

Good luck

Mike

Great video, Mayjane, and nice job on the boat too.

Mike do you know if Interlux Perfection can be used on a mast ? I am painting mine this fall. I checked their web site and it does not say. I can contact Inyerlux directly.

I was thinking of using Awlgrip since it definately can be used on aluminium.

Thanks
Gary
