I made this little table to answer the above question. I used the pumps that fit West System's gallon size 201 resin, quart size 205 hardener and 404 thickener. Different container sizes use different size pumps, so this table only works for the above combo.

A "scoop" of thickener is kind of abitrary. I think I used a thin wooden stick 3/4 inch wide, and a full scoop heaped up on about 2 inches of the stick. That is a bit vague, I know. So use the "like" column to judge.

consistency	thickener scoops	pumps	covers (sq in)	like
real thick	1/2	1	60	peanut butter
medium thick	1/4	1	100	mayonaise
thin	none	1	120	runny nose

1. How many square inches on one side of the stem? How many pumps for thick?
2. How many square inches on one side of the frame? How many pumps for thick?
3. How many square inches for the bottom? How many pumps for medium?
