Finding the perfect knobs for your cabinetry or furniture pieces can be a struggle. If you can’t find what you’re looking for at the store, try making your own. Concrete knobs are easy to DIY (Even for complete beginners), cost-effective, and customizable.
We’ll walk you through making these whimsical and sweet heart-shaped concrete knobs. You can adjust the size and color to suit your needs.
- concrete mix
- the water
- the bowl
- Heart shape silicone mold
- Paint brush
- White and pink acrylic paint
How to make step by step:
Step 1: Mix concrete with water
Place the correct ratio of concrete mix and water in a disposable plastic bowl according to the manufacturer’s instructions. Mix with a plastic spoon until your concrete reaches a smooth, paste-like consistency.
(Note: Use a disposal bowl and spoon to mix the concrete. (Don’t use your good bowls or silverware, as they will be difficult to clean later.)
Step 2: Add concrete to a silicone mold
Pour the concrete mixture into your silicone mold. We chose a heart-shaped mold, but you can use any shape.
Use a spoon to fill each mold with concrete. Fill in as many as you want, but add at least a few extra in case something breaks or doesn’t go well.
Step 3: Insert a screw into each small concrete heart
After pouring the concrete mix, insert a screw into each mold. Make sure the head (flat side) of the screw is sunk into the concrete. Try to center the screws so that they are level and level as you install them. Then let the concrete harden overnight.
Step 4: Remove the concrete heart from the mold
After the concrete hardens, pop your knobs out of the mold. The silicone mold is flexible, so you can bend it to make the process easier.
Step 5: Apply a base coat of paint
If necessary, use a piece of sandpaper to blend the imperfections. Then use your paintbrush to apply a coat of base paint to the surface of each knob. We used a pastel pink for the base color of our heart knobs.
Step 6: Add details using a second color or paint
Once your base coat of paint is dry, feel free to add details with a second color of acrylic paint. You can use the same design for all knobs or try something different for each one. Have fun experimenting with a few patterns before you settle on a final design.
