Lime shotcrete mix, a shovel and a trowel were used to achieve this quiet, semi smooth texture.

This surface was achieved by spraying with a lime shotcrete mix and then scraping the surface with a shovel, spraying again and scraping the surface with the edge of a trowel. The lime mix really quiets down the interior of the dome.

The shotcrete used to spray this surface was made up of 12 buckets of sand, ½ bag of cement, and one 50 lbs. bag of lime, mixed with water to the desired consistency. Tip: let the shotcrete mix for at least 5 minutes before you put it in the pump because the lime soaks up a lot of water.
