It’s great to see small scale 3D cob modeling like at Ryan’s site Colorado Cob. I really enjoyed this model and walk through. Working out the details in small scale is so smart! It allows you consider aspects of the design and to solve spatial challenges you might not recognize in paper or Sketchup. While I haven’t done much 3D modeling myself, I definitely will in the future.
I’m trying my hand at structolite ( plaster of paris and perlite ) and fine sand as a base coat for a diamond finish. Something completely new for me, as I’ve usually used a clay alis over a earthen plaster or homemade lime plaster. I am shaping with earthen plaster then adding structolite for a super smooth finish. My goal is to get a dust-free, durable finish in the kitchen and bath areas.
I was at the hardware store looking for helpful tips from the old-timers. One was a plastic spreader for applying and shaping the plaster. One can use old yogurt lids, sans the rim, for applying and burnishing – it’s the same idea.
After using the bondo spreaders for a short time I’m convinced these are worth having in the toolbox. It’s a little thicker plastic and doesn’t break as fast as yogurt lids. This pack has small, medium and large.
Great tools for getting in those strange tight spaces.
