Typically you donít want to use epoxy with mat because of the styrene binders that hold the mat together. Epoxy doesnít wet out through the styrene properly. Use cloth with epoxy unless it is something like 1708 that has 2 layers of cloth with a mat sewn on. Then the mat will wet out because they donít use styrene as a binder but rather sew the mat onto the cloth layers.

Our boat deck has been removed.

Today I started cutting and dry fitting the new plywood. Off to a good start. Really motivating!

Did you end up having to kerf-cut into the underside of the ply to get it to conform to the camber of the frames?

I think itíll take the curve without kerf cuts. I need to support the frames so they hold their shape as I glue and screw the sheets to them.

Double bias around 440gsm has always been my favourite glass.
Loves epoxy, wets out easy, goes around corners easy, generally a pleasure to use.

Thanks Simi 60. I'm thinking I'll put down layer(s) of CSM then woven cloth.

Didn't make any progress the last two days due to YC volunteering and the wx so I've been researching the upcoming steps.

Agree on using polyester resin. Found this on Fisheries website:

When building fiberglass structures using polyester resins, and where impact resistance is important, alternating layers of chopped strand mat and woven fiberglass cloth or roving will result in a stronger structure than using layers of woven cloth alone - which can delaminate under impact.

In this situation, the layers of mat bond to the woven cloth fabric better than the cloth does to itself.

As above, when using epoxy resins, only woven fabrics should be used for the strongest results.

When covering wooden structures - such as a wooden boat - with a layer of fiberglass cloth using polyester resins, you should not apply the woven cloth directly to the wood. Always start with a layer of lightweight mat - which acts as a binder between the wood and the woven fabric.

When cloth fabric is applied directly to wood, it can readily delaminate, whereas if mat is applied first, often the wood will fail before the mat can be peeled off.


Again, when using epoxy resins, cloth can be applied directly to the wood and result in a strong, permanent, bond.


I'll be filling some gaps in the frames with West Systems 610 and using Gel Magic two part adhesive epoxy to bond the ply to the frames.

With such a large surface area to cover the key will be working time and my ability to wet out well.

I like using 1708 which is a biaxial cloth with a mat layer on one side. You donít have the large gaps like with woven roving that fill up with resin.

"In this situation, the layers of mat bond to the woven cloth fabric better than the cloth does to itself."

This true, BUT for best results the lamination should be built up in one day.

"With such a large surface area to cover the key will be working time and my ability to wet out well."

A 7 inch roller with a fence painting roller cover (3/4inch thick) will put a lot of resin on very rapidly. Have a helper follow with a steel roller after the wet out to help the glass not float. .

Cabin sides covering is usually large and thin so the heat of curing wont be a bother.

Our boat deck has been removed.

Didnít make too much progress this weekend despite putting in about 12 hours of labor. So many small things take a ton of time.

I finished all of the dry fitting l, prepped the frames and epoxied the three sections where the stanchions werenít well bedded and got into the frames. Since these will be through bolted and backed I mostly needed to fill the voids and ensure no further deterioration.

I also decided to patch that small section of rot on the back of the Pilothouse. It turned out to be about 12Ē x 4Ē so Iím just dealing with it now.

Travel this week means no weeknight progress but next week should be when I screw and glue the plywood down.

Yep it’s all the small stuff that eats up your time, but it all has to be done. I hate it when the work thang gets in the way of boat work progress. Hang in there. Thanks for taking us along.

Great progress. What will you use for final finish over the plywood? Back to Teak or ?

Greetings,
Mr. A. I can sense your frustration in dealing with the "small things" BUT they really do have to be done don't they? No sense what-so-ever in undertaking such a project and not doing it properly. The more you can eliminate the "coulda', woulda', shoulda'," items, the happier you AND your boat will be. Trust me. Picky is good sometimes...

Thanks all, I appreciate the kind words and encouragement. I thoroughly enjoy the work - it’s rewarding to see progress after a hard days work - so very different than my corporate job.

RT - couldn’t agree more. I look at ownership as stewardship and would like to think I do things well and right with the best interests of boat and any future owners in mind. I also like to know things are done correctly as this is OUR boat right now.

This deck lasted almost 40 years, the one I’m putting down now should last at least that long.

Fiberglass, paint, non-skid. Teak would be nice but it's too expensive in today's dollars for this old boat...not to mention de-teaked, 80's trawlers appear to be more desirable if/when we sell her down the road.

I wish I could find a decent looking, well priced synthetic teak but the good stuff is approaching the cost of real teak and the cheap stuff....well it's cheap.

I would never go back with teak decking, too much ongoing maintenance to say nothing about the cost. Painted nonskid works. I used Kiwigrip on my decks 2 years ago. Great stuff. I had to do a couple of repairs from PO work. It took a long time with 40 grit in my belt sander to get the Kiwigrip off. I was amazed how durable it was.

2nd vote for Kiwigrip. Easy to use; wears well; easy to do small section coating repairs

Deck Non-skid

I've enjoyed reading your thread as we did a complete deck replacement on our 47' sailboat. Our schedule of materials was different, however the non-skid we chose was a latex based compound called Restore Advanced 10X. We've had it on for maybe three years now and can discern no wear. In particular, when at a dock we use the starboard gate and always travel the same path. Recently I wrote a product review on Amazon with two pictures Rust-Oleum-Zinsser-Restore-Advanced-Concrete/dp/B06XWD5MRQ/ref=sr_1_fkmr0_1?keywords=rustoleum+restore+advanc ed+10+x&qid=1554342629&s=gateway&sr=8-1-fkmr0 Another choice. Good work, Doug
