Pesky air bubbles
Hi all, it's me again. Ok so what's the trick to getting rid of the air bubbles in the concrete?? This time I added more water to my mix and it seems to have helped some. I have a hand held vibrator that I used as well as tapping on the surface. I really didn't see that many bubbles coming to the top. My molds are plastic. One is the size of my palm up to the side of a stepping stone. I have been using canola oil as a mold release. You have been so helpful, any suggestions would be appreciated.
