On May 23, 2009 I posted a question about storing gesso without it getting lumpy after being stored over time. MY "problem" is that LUMPS (great gooey globs of gesso, really) form in the gesso when I store the partly empty (partly full?) container. Then I have to deal with the clumpy, lumpy gesso the next time I want to gesso a support. I make my own Masonite panel supports and canvas supports so when I make a "batch" of supports, I use my gesso. I pour the gesso onto the new support then use a 6 inch foam "cabinet & door" paint roller to spread the gesso.
Suggested "solutions" were:
- store the container upside down
- put the gesso in progressively smaller containers expelling the air
- use all of the gesso
After some "experimenting":
- I found that the clumps still formed when storing the gesso container upside down. But now the clumps/lumps are at the bottom of the jar when the container is turned upright.
- Putting the unused gesso in a soft-side plastic bottle (e.g. plastic soda pop bottle) was messy getting the gesso from a quart jar into a one or two liter plastic bottle - even using a funnel. Plus a great deal of gesso stays in the first container. AND small lumps still formed even when the air seems to be pretty much totally expelled.
So . . . . If (WHEN) I use gesso I have to take my lumps! :-) I'll only buy the quart sized containers of gesso although it's a bit more expensive than the larger sizes. AND when I make a bunch of supports I'll try to make enough so that I'll use most if not all of the container. Where's the savings when buying the larger container if I'm spending time unlumping a gessoed support ?
That's my story and I'm sticking to it. :-)
