Cascamite problem
« on: May 12, 2020, 04:58:33 PM »

I have just bought some Cascamite for a particular application. However it doesn't seem to want to dissolve in cold water, it just forms a sticky blob that clings to the stirrer. In the old days it dissolved into a creamy liquid.

Does anyone have any ideas why it doesn't seem to be working?

Granny and eggs etc, are using the powder form and did you add the water slowly stirring constantly. I have many memories of making beautiful cold Cascamite porridge less the oats of course.
      Good luck.

Interesting, I added the powder to water initially as the instructions said. Adding water to the powder seems to work better but not all the water was absorbed. I was hoping to make up a fairly dilute solution. I have stuck some test pieces together anyway.

The reason for using Cascamite is that I used a dilute solution in the past to apply gummed paper strip to a hull to simulate planking. The watery glue was enough to activate the gum on the gumstrip and the cascamite held it very securely to the surface. When gummed paper dries out it contracts slightly and gives a very good base for a smooth finish using sealer, I used to use shellac.

I am also testing the use of Eze Cote which is waterbased to see if this has the same effect with the bonus that it can be used on top as well.

I used Cascamite a lot as a carpenter personally I always added small amounts of the powder to the water and dispersed each amount before adding more.

Sure they say on model railway forums that cascamite changed formulas, a good while back now, like so many things it's apparently not the same as that old tin we all remember sitting on the shelf.  It maybe changed name also at one point but might have changed back. In any case I've heard it's quite different from the old stuff.  Nothing substantiated, just remember allot of posts when I was into model railways again before returning to the mother hobby a few years back.
