I use a back vibrator Homemedic I think is the brand. Pour some in the mold and vibrate for a minute or two than add more untill full.

Hi Bees,

Peak suggested putting it on your dryer while it is on, and it will vibrate the bubbles out.

I have also learned if you put too much mold release on the mold it will also leave bubbles.~~~Lois

Before you fill your molds, make up a mix of just the Portland and admix. Make it a paintable consistency. Then using a paintbrush, paint a thin coat onto your mold, and then proceed as usual. This works for me.

Any more follow-up on the painting procedure?Dena?Steve?
Anyone?Is it weatherproof with sealing ?
PLEEEEEEEEASE!

I haven't had any trouble with the surface chipping. I haven't had much trouble working with a neat mix of just Portland and acrylic admix. I leave it in the mold a little longer than most, to keep it from drying out too fast. A neat mix will dry very fast. Almost like plaster of Paris. That's the only time I've seen it crack. The humidity is pretty high around here. Just make sure you keep it wet. I don't seal my stuff.
