Building a Dome out of Paper (and steel...and cement...)

Step 5 Plastering

Our papercrete based plaster still leaves a lot to be desired. We ended up using a mix of prickly pear cactus juice, old house paint, 1 part paper, 1 part cement. Later there was plenty of cracking on the areas that received a great deal of sun. We have had better success in other types of paper plasters. We used a tirolessa sprayer which made easy work of plastering the inside and outside of the dome. This is another amazing time saving device and it works well with pretty much any type of finish from earthen lime plasters to heavy cement/sand mortars.
