Don’t toss that dented cake pan or silicone mold. With a little concrete and creativity, those thrifted tins become stylish stepping stones and garden accents. This budget-friendly DIY turns cookware into custom pavers you can color, texturize, and decorate to match any outdoor space.
Why cake pans are a smart, low-cost mold for DIY pavers

Cake pans come in endless sizes and shapes. Round, scalloped, novelty, and fluted pans let you skip costly commercial molds. They’re widely available at thrift shops, dollar stores, and garage sales.
- Aluminum pans hold crisp edges for defined patterns.
- Silicone molds release easier and can capture fine detail.
- Deep pans make thicker, stronger stepping stones.
Using household pans also reduces waste. Repurposing old bakeware is greener than buying new plastic forms. This method keeps project costs low while boosting design options.
Essential materials and safety gear for casting concrete pavers
Gather the right supplies before you mix concrete. Preparation speeds the job and prevents mistakes.
- All-purpose concrete mix (for example, high-strength or stepping stone mix).
- Plastic or silicone cake pans in the desired shapes and depths.
- Non-stick spray, petroleum jelly, or a commercial mold release.
- Mixing bucket, shovel, or drill-mounted paddle.
- Measuring cup, water source, and a level surface for curing.
- Optional: concrete color pigments, small stones, shells, or glass gems.
Protective gear is vital: wear gloves, eye protection, and a dust mask or respirator while handling dry mix. Concrete dust can irritate lungs and eyes.
Step-by-step process to make pavers with cake pans
- Clean and prep pans. Remove grease and dust. Apply a thin, even coat of non-stick spray or petroleum jelly to all interior surfaces.
- Mix concrete to a thick, pourable consistency. Follow the manufacturer’s water ratio. Avoid adding too much water; it weakens the cured stone.
- Pour the mix into the prepared pan, filling to the desired depth. Tap the sides gently to release trapped air bubbles.
- Level the top with a trowel or a straight edge. Smoothness is easier to adjust now than later.
- Add decorative pieces by pressing them into the wet surface. For items you want embedded, place them before the concrete skins over.
- Place the filled pans on a flat, protected surface. Cover loosely to slow drying and reduce cracking.
- Allow concrete to cure fully. Curing times vary, but most mixes need at least 24–48 hours before demolding. For full strength, wait up to one week.
- Remove the paver: loosen edges gently, invert the pan, and lift. Use a rubber mallet if needed to ease stubborn molds.
Tip: For walkways, aim for pavers at least 1.5 to 2 inches thick and large enough for a whole foot to land comfortably.
Design ideas: colors, textures and decorative options
Cake pans with detailed rims create built-in borders you can highlight. Here are ways to personalize each paver.
- Colorant powders and liquid pigments tint the entire stone. Mix pigment into the wet concrete for even tone.
- Surface stains or acrylic concrete dyes work after curing for layered looks.
- Embed river rocks, shells, or pebbles in patterns. Press them into the top while concrete is wet.
- Create mosaics with broken tile pieces or glass; choose non-slip materials if pavers will be walked on.
- Use stencils or pressed leaves to leave impressions for a natural texture.
Be cautious with shiny or rounded glass pieces on paths. Decoratives that are slippery, sharp, or not flush can create hazards. For safety, reserve fragile or protruding elements for decorative, non-walkway pavers.
How to get the paver out cleanly and avoid common issues
Rigid pans can stick when detailed patterns or undercuts are present. Try these release and demolding strategies.
- Apply an extra coat of mold release to intricate pans. Petroleum jelly or a commercial release works well.
- Silicone molds often peel away. If using metal pans, gently flex or tap to break suction.
- If edges resist, run a thin knife around the pan perimeter before flipping it over.
- Some makers recommend a light spray of WD-40 or wiping with coconut oil for stubborn release. Test on one pan first.
- Allow adequate cure time. Premature demolding increases the chance of cracking.
Repairing hairline cracks: mix a thin slurry of concrete and water, press into the crack, and smooth. For structural breaks, consider using a concrete adhesive.
Practical tips for durable, walkable results
Thickness, curing, and reinforcement affect longevity. Keep these pointers in mind for pavers you expect to support weight.
- Choose deeper pans or stack forms to reach 1.5–2 inches minimum thickness.
- Consider adding small pieces of rebar or wire mesh for larger stones to reduce cracking.
- Cure pavers in a shaded, stable environment to prevent rapid drying and surface flaking.
- Seal finished stones with a breathable concrete sealer to protect color and reduce staining.
Working in small batches lets you refine consistency and finishes. Experiment on a few test pieces before committing to a full pathway.
