Plaster Blaster

Wow! Compared to bagging, plastering is fast. Do I know what I am doing? Hell NO! Well, I did watch a plaster video at https://plasterscience.com/  and Cal-Earth's Plasters and Finishes and got some hands on at the 4 day Cal-Earth workshop. But this is the Mistake Dome, so let's do this and learn. Did about 12-20% cement mix depending on location and needs. 

Plaster up to the window height all around the whole structure!

Plaster close up of foothold structure. There is a barbed wire knot inside this plaster hold.

Wrapping this dome in a plaster ribbon!

Plaster drying nicely, starting to feel monolithic and imposing instead of fluffy!

Sealed the foam in plaster. Remember, our "plaster is the same as our "in bag" mix with just a bit more cement (maybe 2-5% more)

Plaster close up, little dome hatch. yes there could be some water pooling, but, A. This is a desert with low rainfall, B. This is a nautical porthole salvaged from an actual sea fairing vessel and is very water tight, even if not meant to be upside down and horizontal, C. I am not planning on storing my comic book, vintage record and rare instrument collections directly under the porthole. 

Even in the doorway, plaster all around the whole structure!
