Joinery Glues

[mooretoolsplease]

Hi all,
One of the windows I make is from mitre master.
As I'm sure you have guessed, all of the joints in the system are mitres, which are strengthened with chevrons.
One of the more time consuming parts of the window is cleaning up the glue after it has been joined.
Currently I'm using a polyurethane glue that expands, but takes forever to clean up.
I'm going to be making up some test corners with different glues, but wanted to make sure I had all the bases covered before I start.
What I'm really looking for is something like polyurethane, but that can be cleaned off with a wet rag just after it has been joined.
The ones I'm going to test so far will be standard exterior PVA, cascamite, and a polyurethane which doesn't expand.
Are there any other brands and types of glue I should include in these samples?

Thanks

Matt

I've been using cascamite lately. It cleans off very nicely.
I've also been using old fashioned hot hide glue for non-external joinery. Also cleans well. Easy to use with a microwave I've found. I prepare and keep it in a jam jar with a glass/plastic lid. I give it a belt of heat before I put the lid back on tight and it keeps well without going mouldy and stays useable.

Jacob, hide glue stored in a jam jar and heated in the microwave - how long will it be before you mistakenly spread it on your toast or pour it over your porridge? ;D

Cheers ;D

If Jacob does that, I would think his sense of smell has gone for a long walk

mrs G quite liked it. She put it on thin like marmite and wondered if it was far eastern, fermented soya or whatever. Mind you she eats loads of chilli and I think her taste buds are shot. And the gin and the baileys

I only really use cascamite / extramite or white PVA for external work . I tried some quick grab glue the other week and found it useless so its back to the PVA . Tite bond origional is good but ive not tried titebond 3 .

which PU glue are you using.
I think that Gorilla glue is pretty C@*P I tried it when I was making a stair out in America.
I use Everbuild and at £2.90 a tube you can't go wrong. Wether it be gel or liquid.

Could that be a bit like too much glue going on? After all PU glues only foam out when they are not under pressure, i.e. in voids, etc. One trick I've used is to mask-off the joints, but for a production job that's way too much hassle.

I'm going to suggest that you look at something a little more specialised. Cascamite is a one-part UF glue. It also hasn't got the greatest of shelf lifes against PVA (about 12 months). Possibly a better solution might be to go to a 2-part UF glue such as Unibond 800. As a rule 2-part UFs are more water-resistant than 1-parts and they have a shorter setting time, too (about 2 hours at 20°C for 2-part as opposed to about 4 hours for 1-part). Also a lot of the clean-up can be done whilst the glue is still wet, just don't use hot water.

A simplier approach might be to try one of the "new generation" D3/D4 PVAs which have appeared over the last couple of years. I've tried the Wurth D3/D4 and it seems as good as anything else I've been offered in the PVA line

PS Did you know that acetone is pretty good for cleaning up excess PU squeeze-out, as long as it's applied before the glue is fully set

Titebond III for me, but then I don't make 100 windows at a time.
