I certainly haven't heard of that technique to get rid of bubbles in the cement.

They make industrial versions of the same specifically for concrete.

Well now I'm going to make a dildo out of concrete and list it on Amazon just to fuck with builders.

Vibration? Thought it was pretty common.

The article does mention a very specific choice of vibration equipment.

Same method though. There's a plethora of vibrating things to choose from. I suppose you could mold a large silicone tentacle to put on a jackhammer, too, and use that to fish for bubbles in your cement soup. Call the tool what you want, you haven't changed the method.

Yes, I did feel a bit silly buying and using it, but to be fair it did get the bubbles out.

Are you guys all trying hard not to say the words dildo, satisfier, or sex toy? Why so? AFAIK it is neither a rude nor a prohibited word.

Nah, I was just being pedantic about the “method” of removing bubbles.

I've seen people use the same technique and tooling for resin pours.

If it works, it works
