plaster wedging board bad?

updated sat 11 nov 06

 

Donna Kat on thu 9 nov 06


Before leaving on a long trip (6 months) I made a new wedging board. I
just recently got around to using it and as I was wedging I noticed little
pin head size pieces coming out of the board and into my clay. Is there
any way to salvage this board? It was poured into a very heavy duty wood
frame and I hate to lose it.

Stretch tightly a piece of heavy painters canvas over it, tack it down
not on top of the wood frame, but on the sides of the frame, then add a
3/4 inch wooden holding strip around the entire box. Enjoy your wedging
once again.

You may need to adjust the tension on the canvas periodically as it
stretches, so use screws instead of nails.

Donna,
Just cover it with a heavy canvas. No more plaster and does the same job
in preparing the clay.

Before leaving on a long trip (6 months) I made a new wedging board. I
just recently got around to using it and as I was wedging I noticed
little
pin head size pieces coming out of the board and into my clay. Is there
any way to salvage this board? It was poured into a very heavy duty
wood
frame and I hate to lose it.

More than likely this small pieces of plaster coming loose are due to air
pockets at the surface of the plaster bat.

Not sure of the best method to resolve this, but you might try repeated
slamming of clay down on the surface to break loose all covered air pockets.
The moist clay will pick up the bits of plaster.
Throw this clay away.

Alternatively, you could scrap the entire surface (there are plaster tools
for this) until you get down to an un-pitted surface.

You could also stretch canvas over the plaster also.

Staple a piece of canvas over it.

YES! Thanks!!! I just read a post about not liking plaster or canvas
which led me to hope that gosh I might cover it with canvas. I'm so happy
to hear this will work.
