I make myself something from concrete that’s a little more practical, even though I still wanted to keep it simple. That’s how I came up with this DIY concrete door stopper idea!
Oil the mold:
Use your paintbrush to brush the entire inside of your bottom tube half with oil. Make sure you coat the whole bottom and all of the sides well.
Spoon in the cement:
Use your spoon to fill the inside of the tube entirely with concrete mix. Leave a little bit of space at the top just to make sure nothing spills over.
