Concrete looks heavy, expensive and permanent. Which is exactly why it is so fun to make yourself.
The process is simple. Mix, pour, wait, pop it out. The mold does most of the hard work.
One bag of concrete can turn into stepping stones, planters, a bird bath or a whole garden path.
Here are 15 concrete molds DIY ideas for the garden and home, with tips to get a clean result on your very first pour.
1Pour a Large Concrete Planter
A big concrete planter looks like it cost ten times what you spent.
A silicone planter mold bends away from the cured concrete, so big pieces come out without cracking. Always drill or mold in a drainage hole.
- High end look
- Clean release
- Statement piece
Project Card · 1 hour plus 2 days curing · Medium
Materials Needed
- Large silicone planter mold
- Concrete mix
- Bucket and mixing stick
- Gloves, safety glasses and a dust mask
- A smaller plastic pot for the inner cavity
- Cooking spray as a release agent
How to Make It
- Spray the inside of the mold lightly.
- Mix concrete to a thick, smooth oatmeal texture with no dry lumps.
- Pour a base layer and tap the sides to release air bubbles.
- Press the smaller pot into the center, weight it with stones and fill around it.
- Cure at least 48 hours, then remove the inner pot and peel off the mold.
My Pick
Large Silicone Concrete Planter Mold
Flexible silicone that peels off big pours cleanly without cracking them.

- Lasts for years
My Pick
Concrete Bird Bath Mold
Basin and pedestal molds for a heavy, permanent bird bath.

Frequently Asked Questions
What is the best concrete mix for molds?
A fine, sand rich mix or quick set concrete works best for small molds. Coarse gravel mixes are better for big slabs and pavers.
How long should concrete cure before removing the mold?
Most small pieces can be demolded after 24 to 48 hours. Big planters and table tops need longer, and full strength takes about 28 days.
How do I stop concrete sticking to the mold?
Spray the mold lightly with cooking spray or a concrete release agent before pouring.
Is working with concrete safe?
Wet concrete can burn skin, so wear gloves and long sleeves. Wear a dust mask when mixing the dry powder.
