Mixing the Plaster
 Note: For best results, mix the plaster and color 4Ð8 hours prior to application.
Unlike other plasters, the workability of American Clay plasters improves the
longer you let the mix stand. You can actually mix our plasters up to 24 hours
before youÕre ready to start the job or at any convenient time 30 minutes
or more before application. If the plaster thickens when standing or during
application, just add additional water and remix to a pudding-like consistency.
If you are using American Clay Add-Mix as a hardening agent for Loma or
Porcelina, see instructions on the following page.
In general, each 50 lb. bag or bucket of American Clay Earth Plaster should be
mixed with approximately 2Ð3 gallons of water. You may need a bit more or
less water to bring the plaster to the correct consistency (similar to pudding).
 1. Measure 1-3/4 gallons of water (or
Add-Mix) into a clean 5-gallon bucket, a 15-
gallon plastic utility tub, or other suitable
container. Slowly add about half of one
50 lb. container of American Clay Earth
Plaster.
 2. Prepare your plaster color by mixing water with the pigment
in the American Clay Color Pack container. Stir well to create
a smooth, thick paste, adding a little water, if necessary.
Empty the paste onto the plaster, rinse the color pack with a
bit of the water, and add this rinse to the plaster also.
 3. Mix the plaster and color with a heavy-duty 1/2-inch drill
equipped with a mixing paddle. Keep the drill at low speed
to avoid introducing air into the mix. Continue to add all of
the dry plaster from the 50lb bag, adding additional water
until the plaster has the approximate consistency of
pudding and the pigment is blended evenly throughout
the plaster.
4. Let the plaster stand for at least 30 minutes. Before troweling it on the wall,
check the plaster, adding water and remixing as necessary to bring it back to
the consistency of pudding. 13/4 Gal.
