4. Application for becoming an Affiliate for Colson eBooks providing a residual income to the subscriber. Only available through this Newsletter.

This Newsletter Publication provides techniques on How To Mix Plaster, a sub portion of a yet to publish eBook: ARCHITECTURAL TILES. Note that access to video clips on this subject will greatly help to enhance the understanding and success for mixing plaster.


There are several methods taught in the preparation of mixing plaster. One of the most common is to use a water to plaster ratio to assure good strength during the setting up process. However, the following method for mixing plaster has proven itself over and over again, for both small, as well as large pieces.


1. Place water into a plastic or non porous pail.

Do not fill more than half.

2. Sprinkle powdered plaster onto the water surface continuously until it will not longer sink below the surface. Allow a small buildup of the material to peak above the water’s surface. This will assure you that you have a proper ratio of water and plaster.

3. Allow the mixture to sit without stirring for

at least 1 to 3 minuets.

4. Stir the plaster, either with a spatula, or with your hand.

In either case, stir from the bottom of the pail,

up in a circular fashion.

5. Allow the this entropic action to begin. This means allowing the plaster to thicken. In warm weather and warm water, this might take eight to twelve minutes. In cold weather, and cold water,

it could take longer.

When the plaster has thickened to the point that you can draw your finger across the surface mixture, leaving a slight line indenture, you are ready to pour the plaster into your pre-prepared mold.

1. It is often helpful to use a drop of two of wetting agent in the water homogeneous and help to prevent making air bubbles in the mix. A universal wetting agent is liquid dish detergent. Only a few drops will do the job
2. Pounding on the table surface next to the pail of mixed plaster will often force air bubbles to rise to the top and disperse. Sometimes the effect can be the same as

pounding on a table surface.
3. To accelerate the setting up of plaster, use warm water for mixing, and to slow down the thickenscopic action,

use cold water.
