Lime plaster is the source of a lot of confusion for folks, myself included. It’s taken a long time to understand even the basic ins and outs of hydraulic lime, hydrated lime, slaking, carbonation, blah blah blah. When you start to read and hear about lime plaster, it sounds a bit like alchemy. Which it kinda is. Lime is totally unlike clay plaster, which seems so simple and innocent in comparison. Lime plastering is, after all, a chemical process that you really want to ensure goes according to plan.
This spring is all about plaster. I’ve been hired to complete the plaster work on a faswall block home in western Kentucky, including the clay plaster interior and a lime plaster exterior. There’s 3500+ total square feet of wall between the interior and exterior, which is no slouch. I just returned home from completing the clay and lime base coats with our crew. It was a big push and I’m glad to be done… well, at least until it’s time to go back and apply the finish, anyway.
