What makes the clay stick to the walls?

During a recent clay consultation I was asked what ingredients in American Clay make it "set up", or harden on the walls. Many other plasters and similar products, such as concrete, have ingredients that cause a chemical reaction and make the substance harden as it dries. The client had a hard time understanding that there aren't any ingredients that will cause this type of reaction to occur. So what makes the clay hard?

Here's the secret...ELBOW GREASE, and lots of it! Here's a picture of clay being compressed in a Church Hill residence. You can almost see the sweat...oh, and the blisters.

American Clay is made from 100% natural, non-toxic ingredients. Its strength and durability come from a mechanical bond created during the final stage of installation, called compression. Without compression, the clay will feel rough, dusty, and more like...dirt. As American Clay always says, "In order to impress, you must compress".
