Best there is for laminatingI've been using Cascamite in it's various names for more years than I can remember, certainly since the early sixties and I've yet to find anything to compare with it for laminating, which is what I do most. Particularly chairs and tables etc. The open time is superb, more especially as I have lived in the South West of France for the past 14 years where summer temperatures easily go over 30 and occasionally 40 Centigrade. With regard to shelf life I keep mine as cool as possible and well sealed and have used some as old as a year without any sign of degradation, but, usually I'm through a 6kg pack within a few days.

Why Isn't It More PopularCascamite is such a great adhesive I'm astonished it isn't more widely used. In particular you get about an hour of "open" time (or at least you do on all but the very hottest few days of a British summer!) which makes it perfect for complicated glue ups. Plus it's a gap filling glue so if your mortice and tenons aren't quite perfect this is definitely the glue to use. Finally, I find it easier to clean up any squeeze out than with PVA (I use an old toothbrush and very hot water) so it doesn't mar the finish.

Worth getting for exterior joineryI've used Cascamite for decades. Some pine garden benches I made around 20 years ago finally rotted around the glued joints which were still firm. It's a bit harder to use than PVA because you have to mix it up each time. Add powder to water and aim for a thick cream consistency. Wipe off surplus very thoroughly with a wet cloth to avoid unsightly patches where a stain won't soak in. Don't buy more than you need because it goes off after opening.
