Step 1: Mix the Concrete
1:06
Mix your concrete in a bucket following the ratio printed on the bag. Megan uses a quick-set concrete she had on hand and adds a splash of extra water so the mix pours a little runnier. A looser mix fills small molds cleanly and settles into the corners instead of leaving voids.
Stir with a paint stick until there are no dry pockets and it looks like thick oatmeal. Do not go too soupy or the block ends up weak. You want it pourable but still holding its shape on the stick.
Tip
Watch this step Add the water in small pours. It is easy to loosen a stiff mix and almost impossible to un-soup one that has gone too wet.
