Cleaning Plaster?
Question:My art teacher has my class making life-size plaster figures. We're using gauze that has been pre-coated with plaster dust.
It makes an awful mess because she won't let us brush the plaster dust to the floor before we wipe down the tables. She can't figure out that the tables aren't clean because the plaster dust mixes with the water in the sponge to make liquid plaster that hardens in a film over the tables.
She makes us wash the tables over and over. Is there anything we can do to get the tables clean? We can't use the water anymore! My hands are so dry. Yesturday I had to wash my hands three times! Is there an oil-based solution we could bring in to clean the table once and for all?
**If it makes a difference, the tables are made of solid wood. They have a poly coating on them. It's a shame because the tables were sanded and coated last summer and they're from the '30s when the school was built. Now they're covered in hardened plaster!
Answers:
I used a large amount of water. The best way is to put the table outside and spray it with a water hose. Or if there is drainage in the room you could dump buckets of water over it. Washing it with a damp rag is probably just smearing it in.
you just need to use lots of water. Once you get it clean cover the table w/ a cheap table cloth or some brown paper
