Thread: epoxy glue

Cure time of epoxy is very temperature dependant. Most of the time overnight should do but in very cold climates it could potentially be days.

When I use epoxy I leave the mixing container near the work and check it before releasing clamps. If the dregs left in the container are still soft then it's too soon. As for sanding, similar thing although a more stringent test of the dregs with a fingernail or screwdriver is used to see how hard the epoxy is. It's a hard thing to describe but if it is difficult to leave an impression then I consider it OK. Bear in mind that full cure takes some days (or more in the cold) so you will be able to leave some sort of impression for a while (forever if you are heavy handed).

I'm pretty sure this info is on their web site. I know the Techniglue website has their info on its site, very valuable info for the various hardeners used

Cheers for the info guys apparently once it's set it's set due to being a chemical reaction so I've been informed from an old school boat builder he said if it is not rock hard in 24hrs or a smidge longer when cold temp then you've stuffed up your mix ratio.

I have used the West Systems for making a veneered hall table simply for the application of the veneer lay-on and was left in the vacuum bag overnight.
You could use Titebond II OR III for your tabletops and shouldn't be any problem with it, I doubt many people use epoxy for edge to edge joints but it's Personal choice and if it works for you then go for it.

It's not a 'near enough is good enough' type of mix...aim to be out by less than 2% in your mix ratio by weight, so for a 5:1 mix that's 100 grams and 20 grams, not 17 grams or 23 grams!

MS, you took the words out of my mouth. Get it wrong and you have a sticky mess.
