/diy/ - Do It Yourself

Round two
this time portland cement hand mixed with play sand and water, I gotta stop just eyeballing it. it kind of seperated into just water on top, and then leaked water out the sides and bottom of the mold. This is why the top (bottom) of the planter isn't flat

shaking out the air bubbles definitely helped and so did the material change.

I opened up the two shells too soon i reckon and resulted in some cracking on the edge, so I'm gonna wait before I try to remove the core
