Osmosis Blister Repair and Hand Painting Our Hull - Episode 69
The boat work continues this week as we fair minor repairs on the hull, fibreglass the large holes caused from osmosis blistering and demonstrate how we hand painted the primer and 2-pack polyurethane paint on to the topsides of our hull using the easy and cost effective "Roll and Tip Method".
The book we strongly recommend in this episode if you are considering purchasing or doing any refit work to a fibreglass sailboat is "This Old Boat" by Don Casey. We found it an invaluable resource that we referred to many times during our refit at the boatyard.
We hope you enjoy this one, it took much longer than the others to edit and put together with lots of voiceovers, cuts, time lapses and music. Apologies again for the terrible audio during the osmosis blister repair demonstration it was exceptionally noisy in the boatyard that day!

Working hard I see nothing like a successful removal of peel ply is there.
:)
Excellent!! I bought Casey's compilation book called the "Sailboat Maintenance Manual", which I think includes much of the material in This Old Boat, as well as several of his other books. It's fantastic! It was great to see your repairs and tutorial on the tip and roll application here. At first I though you missed a couple of spots on the primer, and then realized my monitor was dirty ;)
He does a very thorough job of explaining things. He and Nigel Caulder have contributed such a great deal to the boating community. I'm still getting used to wearing glasses and sometimes I think they aren't working very well untill I examine them and find they are dirty. 😂
TY for the cool video. Team work! BTW, how did you get the hull under the support strut pads taken care of. Did you have a 5th one to lift with to expose the other 4 individually?
We got the struts moved and he boat supported by side beams. The yard labourer was a very agreeable fella and we got on well.
Troy, next time sanding fibreglass rub in baby powder on your exposed skin, stops the itch (only just found this out), where did you get the TSP from?, Jota cote 605 is amazing paint, I have used it in all my lockers, hardens up like armour, if you put is on thick enough it looks like gellcoat. One last question, Are you happy with the finish of your topcoat (out of a hundred). Sorry for the questions, I am in the process of bogging my catamaran getting ready to fair and then paint so any info is good info, did not know Jotun has a roll and tip top coat, was going to use international paints but would need to donate a kidney to afford their prices, I can buy jotun at trade price so you certainly pricked my interest. If you get down to Brisbane for a meet up I will bring photos she is a 12m easy catamaran epoxy ply sandwich hopefully launching this year. Thanks John
We aren't top practitioners of roll and tipping, so our job won't compare to a spray job. Also, the hotter temperatures during the work meant we really should have thinned it by 5%. The book we recommend , This Old Boat, mentions getting a panel of glass to do a quick job on and seeing if the thickness is correct for conditions. Jotun do great data sheets and they detail whether the paint you have chosen can be brushed and sprayed. A word to the supplier may also clear things up. Again, it takes a fair bit of experience to match a spray job with roll and tipping but on our old boat, I can live with a rougher finish. Often times, there's no one to see it but us! By the way, the baby powder works very well, as does a hot shower at the end.
What a team. "And, as always, Pascal is right beside me."
It's rare that we are out of each other's sight and are yet to run out of conversation and new things to aim for together. It's a real gift and one that's very appreciated.
