How easy is it to make a DIY concrete countertop?

We are planning to build concrete countertops for our BBQ and fireplace, but I have never attempted something like this so I thought it would be wise to build a test countertop first, to see if I can really do this and have it come out looking good.

A reciprocating saw (w/out bade) or a palm sander work really well in removing air from the mix.

I tried the palm sander, didn't seem to do much. Never thought of the reciprocating saw. Thanks

I like the last 3-d shot. Overall, looks cool. Can’t wait to see the finished product. 😊

Thanks, me too!
