[alt-photo] Re: Egg-tempera as primer for impermeable surfaces

[Loris Medici]

Thanks,

That didn't work for me the way I like it; I want a streak and crack free
surface and - relatively - quick operation.

Now, tempera's interesting (and I'm going to try it) because it's very
sticky, dries very fast and can be hardened w/o dichromate or formaldehyde;
I plan to use isopropyl alcohol to harden it. (A liter per USD 1.50 here and
I plan to recycle many times...) Sounds pretty practical - if it happens to
work, of course!

Regards,
Loris.

Hi Loris,

I have not tried egg tempera.  The gelatin mix I use has served me well.
Mix is up as if you were going to size paper, but include the marble dust
and apply two coats.

Good luck!
