Water Cure CSA Concrete
So I pulled back the plastic and wetted the concrete for an hour while it cured.
Remove Countertop from Form
The next day I removed the strap holding the plastic pipe in place as well as the screws from underneath.
Marilyn came to help me flip the counter over. I removed all the screws and sides of the form and the melamine bottom of the form came free.
The plastic pipe came out fairly easily with some tapping from underneath.
To remove the plywood disc I drilled a hole in it and made a cut with a jig saw. This allowed the sided to come away from the concrete so I could tap the disc free.
I used a small block of concrete left over from a previous experiment to smooth the rough edges along the bottom of the countertop.
DIY Stainless Steel Sink
I cut a hole in the bottom of this stainless steel bowl to add a sink trap. A bar sink would be a good option as well for this potting bench.
And really, this bench would make a good outdoor food prep station beside a barbecue.
