wood glue for damp wood

[chrishelen]

Hi, i have cut out a piece of wood from my main hatch ready to scarph a new piece in, the wood is sound but damp, at the moment it is not possible to take the hatch home and dry it out first.

my question is is there a type of glue i can use that will adhere to damp wood?

Thanks.

Polyurethane glues require the wood to be dampened before glueing as the glue needs moisture to cure, so I would use one of them. The most hyped is Balcotan but I have used cheaper polyurethane glues with perfectly good results.

Polyurethane glues can be excellent for this type of work but they also need the timber to be very clean and in good condition.
They are not a strong filler although they will foam up where there is space.
Their main strengths are gained when timbers are tightly clamped or attached together having the glue well rubbed into the adjoining surfaces with no air spaces. If no clamps can be attached, then perhaps strong woodscrews would suffice.
There are some 5 minute polyurethanes and others which give longer setting times, 20/30 minute

Cascamite. Been available forever and still the best! Being water based it will draw some of the damp out of the wood as it cures.

Titebond, but I guess that is one of a wide range of Polyurathanes....

Thanks guys, is cascomite sold under a different name these days?

It's spelled Cascamite, see here for links. I've never used it but it certainly has strong adherents

Fastgrab by Wudcare - http://www.wudcare.co.uk/fastgrab.htm - Have been using it for a few years. Excellent on damp wood and foams to fill voids so don't over apply and use masking tape on adjacent surfaces which need to be kept glue free. DON'T get it on your hands, it stains skin.

I've used Gorilla glue. Widely available and works well.

Don't want to start an anchor type argument but Cascamite and Aerolite were (are?) only water resistant; used for dinghy construction so I suppose OK for a hatch or where not permanently immersed. Not sure about their effectiveness on damp wood but the polyurethanes will work on that and are more waterproof and even easier to use - no mixing. I'd use them.
I'd dovetailed up a tool box and used Cascamite - it fell apart last year .....but it was 40 years old.

EvoStick "Sticks Like Sh*t" Is A Good Outdoor Glue

I have used Cascamite for years. It needs to be stored quite dry or it goes off in the tub, still, its a good glue for outdoor use. I have converted to EvoSticks "Sticks Like Sh*t" (correct spelling by the way), available from Screwfix. Its proved to be a durable glue. Some users comments on the link below as well.

I think I would agree with the suggestion to use one of the moisture cured polyurethane adhesives such as Balcotan

Cascamite never worked well for me. Not suitable for the application nor especially the damp conditions I would think.

I preferred Aerolite 306 to Cascamite but again I would think maybe not a good choice for damp wood.

Available just about everywhere, much easier to find than the others mentioned and equally as good.

Hi guys, i managed to find a small tub of cascamite for £5.80 at my local small DIY, and have done the job, hope it works, but i must say it was a bit messy mixing the stuff up and a gust of wind blew some of it over my sandwich as i was mixing.

I am a fan of the gap filling adhesives, but we will see when i go back to the boat in the morning if this stuff works, some of the older guys at my club swear by Cascamite.
Thanks again.

Keep it well clamped up for a few days.
Esp important for hard woods and even more so at the current low temps.

I think impatience was probably the reason for my bad experiences with it.

I've used Cascamite in days gone by with great success but not on damp wood. It does not harden as quickly and needs to stay unstressed and clamped for a lot longer than a good polyurethane, especialy in cooler weather. I'd leave it for a good week before 'testing'.

Gap filling adhesives other than two pack resins containing a 'filler' or 'grog', rarely have any strength at all in the area of the gap being filled, especially the polyurethanes.
Any gaps filled with Cascamite will have a very crystal like make up and little or no flexibility or strength unless mixed with a fine filler such as wood dust.

I'll ignore all the unfounded nonsense and stick with Cascamite as it is still the best after some 60 years on the market.

In my experience it can be a brilliant glue.
If used on timber that will be flexing such as a laminated tiller of something like ash (which I had on my last boat) it could give way after time as it really is quite brittle and not flexible.
