Captains tolley seal and cure windows

[the fox]

Hello . myself and partner are newbie to boating 

Just bought norman 23 

Windows are my question?

How good is the captain's Tolley seal and cure 

Do windows need to be dry ?

To apply this liquid ,? 

There only seems to be one window showing a leak 🥴

Yet with hope 😳

This could only be condensation 😄

We are going to be in the process of cleaning all the windows due to green moss Inthe sliders of these windows 😏

We are preparing for time spent on our boat 

To get windows sorted with the correct appliance ,,🫣

Any advice on doing so ? 

 

Thank you all for any help 

And 

A huge hello ,we both can't wait to get out on the canal 

The fox 🦊,,,,,

Captain Tolleys is a good temporary fix.

 

The windows do need to be dry and the liquid creeps into any cracks, you may need to apply several times to get a good seal.

 

Welcome aboard.

[the fox]

Thank you kendorr 

Very grateful for help 

Will make sure of them  being dry

Check if your window frames have drain holes - they are prone to getting blocked up, and it sounds like yours haven't been cleaned for a while!!

I have not analysed the Captain's wonder stuff but I suspect that it is waterproof PVA, as in waterproof white wood glue sold as Evode wood glue in the blue bottles.  A much cheaper way to buy it!

Captain Tolleys works by capillary action so gets “sucked” into narrow cracks. It won’t work on wide cracks but is very good for applications like yours

I suspect you are right, however the Captain Tolley's I have used is much thinner than usual PVA, I doubt standard PVA would be much good at capillary creep.

Sorry I don’t think it is anything like PVA. More like an incredibly thin isocryonlate ( super glue). It’s brilliant stuff for some jobs and worth every penny. Real get you out of the sh.t stuff! It gets sucked into thin cracks like it’s on a mission then expands and sets.

I haven't come across this as a suggestion before.  Have you experience of it expanding? An interesting property for such a use.

Funnily enough, I was talking to another boater in the marina only the other day, who was re-bedding his windows. I mentioned Capt Tolley's, and he remarked that it was PVA, it also contains some alcohol and a fungicide. For some reason, they stay pretty quiet about what is in it. Perhaps unpatentable, so trade secret is their only protection.

 

It has been about long before isocyanate became popular.

I could be completely wrong. It could be incredibly thin quick setting PVA so please disregard my previous and apologies to Hider

It is bloody good stuff. That’s praobably my only statement you can rely on. Their website is also quite good and says nothing about expanding.

Some Polyurethane glues expand when they set if that’s what you are looking for

If you run a bead  of Capt Tolly's Creeping Crack Cure along the top of the window frame and then watch it you'll see it sink into any wee holes, if so do it again and watch it. When it stops sinking into any holes, it's done.  Clean the window channels with soapy water and your tooth brush which is ideal.

So far as i know (or have encountered) in industry, no PVA adhesive is waterproof, certainly no water based formulation  - some more than other formulations are highly water resistent.

Technically all the adhesives i have encountered that are waterproof are EVA or EVA/PVA modified based compounds

 

The blue woodwork glue often referred to as ( exterior ) PVA does not have PVA listed as its base - that was on the older green woodworking adhesive used for internal joinery for many years though far less readily found nowadays.

 

PVA  used on priming walls etc before rendering is intended to slow the absorption of water into the brickwork/substrate NOT to stop it - an older method was simply to ensure the bricks were soaked first to give the same effect - using PVA only simlifies the task for builders.

 

Penetration of an adhesive (or any thing) into small cracks is essentially determined by the degree of adhesion vs cohesion forces at work.

My error, EVA is the waterproof one.

I guess there must be different types of EVA. The expensive  pH-neutral stuff I use for bookbinding is definitely water-soluble. It dries quickly, which can be an advantage when speed is important,   and is used as a safe alternative to the traditional slow-drying flour and water paste. Some types of PVA, especially those used for joinery, are somewhat acidic and are unsuitable for bookbinding where archival permanence is required.

Doubt it is. Been around too many years. I'm in the Watered Down PVA camp. Excellent for minor leaks and lasts in the bottle for years.

Me too, but I suspect it has something like a detergent in it to minimise surface tension so it creeps into the cracks.

No, I have used Captain Tolley and was just interested in the idea of it expanding.  It would probably be even better if it expanded, its pretty good as it is.

Many many moons ago I comprehensively renovated an ancient Mirror sailing dinghy for my  daughters. When we launched it, it leaked through an invisible crack in the centreboard case and I was mortified. At the sailing club someone said don’t fear and produced  some Captains Tolleys. He said it would find the crack, fill it and expand. Half an hour later it was watertight and despite being extensively used never leaked again. He may have been wrong about the expanding, according to the website it flows into a flexible seal, but it worked  incredibly well and I’ve been a fan ever since. 

i suppose it could be better if it expanded a bit though some polyurethanes expand too much, if allowed, and lose their structural strength

Apologies if I misled you

It has been about long before isocyanate became popular.

 

Captain Tolly's Creeping Crack Cure came onto the market in 1986. Cyanoacrylate glue was first available for sale to the general public by the early 1960's, albeit quite difficult to find at the time. I used to get hold of it from a friend who worked for a company who made aircraft ejector seats, it was used to glue the seams on their silk parachutes.

 

Back to the topic - I used Captain Tolly's on the windows of Helvetia, and it worked brilliantly.
