DIY Rectangular Flower Vases Made From Cement

I’m crafting stuff for my DIY wedding and I realized I needed flower vases. So, I tried making my own using cement and I’m sharing the step-by-step tutorial with you.

1. A bag of fine white concrete
2. Water
3. Plastic recipients
4. Spoon
5. A damp cloth
6. Scissors or cutter
7. Sandpaper / Sanding machine
8. Dust mask
9. Protective gloves

I used 4 rectangular plastic water bottles for my molds, two large and two small.

if you don’t know how to make molds for concrete/cement flower vases or planters just turn to your plastic recipients. Even a plastic cup will be of use. Or cardboard boxes like those for milk and juice. Put protective tape on the corners to make sure it keeps its shape while it dries.

I used a cutter and scissors to cut my plastic bottles to the desired length.

I used two parts concrete and one part tap water. I didn’t know how much I needed for my two molds, so I made the same mix three times.

I poured straight from my casserole into the molds. The first time I didn’t take into account there was another plastic bottle that would come into the middle and I poured too much of the mix so it ended up looking a bit messy.

I filled the center bottles with water to make sure they don’t pop out of my exterior mold. I also slowly tapped the molds against the ground to take out any air bubbles.

I waited for 24 hrs for the cement to dry and turn into concrete. It’s the first time I ever have to wait for some craft project to be complete. I didn’t think I would be patient enough, but I filled my day making some new paper flowers. So, one day passed and it was safe to break the molds and take out my vases.

The plastic water bottles I used for molds left a strong mark so I needed to tone that down. I used sandpaper but it was taking too long. So I used a sanding machine to remove the letter marks and give the vases a fine, smooth look.
