Learn How to Use Concrete Molds, and Paint Concrete Statues


On this page, you’ll discover step-by-step instructions for using concrete molds to create stunning garden décor and statues. We’ll cover how to pour concrete into molds, how to mix, recipes for concrete, and painting tips for concrete statues. You’ll also learn how to apply concrete acid stain to achieve rich, long-lasting color on your finished pieces.

How to mix concrete.

Always measure everything, as you can not improve your mix if you can not remember how much you used in the last mix. The most common mix for making your own concrete is probably the one two three mix. Which means just what it says, one part Portland cement, two parts sand and up to three parts small gravel. If you are pouring smaller statues you will use less and or smaller pea gravel. Sand should be a man made,Sharp or a River Sand the River Sand will have some small gravel in it. Almost any sand will work, but you do not want to use a play sand as it has been polished. Gravel should be Pea sized or smaller. This is just a basic mix to get you started. You can also use the 1-3-3 mix which is about a 3000 psi mix you would get from a concrete plant, as you start to make more statues you will find the mix that works for you. You will want your mix to have just enough water to make it pourable but not runny, as too much water will make concrete weak, but too dry of a mix and your statues will have lots of air holes in them. Casting statues is like anything else,the more you do it the better you will get at doing it. There are also water reducers that you can use to help improve your mix and to make your mix more fluid and also improve the strength of your concrete. You can find a short video of this in the info section under plasticizer. As I said before, this is just a starting point, should you need more help or have questions please feel free to email me or call me. If you are using pre-mixed concrete, then you will just be adding water. So for this mix you just need something to mix it in and add water, following the same rules as above try not to get too much water. You want the mix to be about like oatmeal consistency. I hope to add a few videos this spring about mixing and pouring molds, so keep checking back for more info. Information was from a concrete batch plant. 1-3-3 = 3000 psi concrete 1-2-2 = 4500 psi concrete


Painting Concrete Statues

Painting concrete statues is a simple way to add beauty, highlight details, and protect your piece for years to come. How to Choose the Right Colors for Your Concrete Statue When it comes to picking paint colors for your concrete statue, let your creativity take the lead—there’s really no wrong choice. You can go for natural, earthy tones if you want your statue to blend seamlessly into the garden, or select bold, vibrant shades to make it a true focal point. Here are a few ideas to get you started:

Animal statues: Stick with realistic colors or add a playful twist with unexpected hues. Stone or garden forms: Grays, browns, and subtle greens give a classic, weathered look. Accent pieces: Bright colors create fun pops that draw the eye and inject personality.

If you’re feeling stuck, draw inspiration from your surroundings—check out the plants in your yard, the bark on nearby trees, or even the colors used by neighbors. A stroll through local parks or a quick online search (Pinterest is packed with examples) can be great for sparking ideas. Don’t be afraid to mix and match. Sometimes, layering different shades or adding highlights with a lighter or darker version of your base color can help details stand out and give your piece extra depth. And remember, it’s all about making something you’ll enjoy looking at for years to come. The best results come from using a high-quality latex paint like Smith brand paints has been used for decades. For the first coat, thin the paint until it’s almost a pastel shade—this allows the concrete to absorb it and creates a natural primer coat that bonds well to the surface. After that, you can apply your next coats of concrete statue paint at full strength for rich, even coverage.Make sure to wash the stone to remove any mold release left behind.

Cleaning Debris and Dirt from Concrete Statues

Before you dive into painting, it’s important to start with a clean surface. For most garden statues, a gentle cleaning is all you need. Use a soft-bristled brush—an old paintbrush or a natural fiber brush works well—to sweep away cobwebs, loose dirt, and debris. Avoid using a stiff-bristled brush or wire brush, as these can scratch or gouge the surface of your statue, especially if there are fine details you’d like to preserve. If your statue isn’t heavily soiled, dry brushing is often enough to tidy things up. This method is fast, requires no water, and helps keep delicate features intact. For statues that have stubborn dirt stuck in crevices, you can lightly dampen the brush or use a cloth, just be sure to let the piece dry thoroughly before applying any paint or stain. This extra step ensures your paint will adhere properly and last for years to come.

How Long to Let Your Painted Statue Dry

After you’ve applied your last coat of paint, it’s important to let your concrete statue dry thoroughly before moving on to sealing or displaying it. Generally, painted concrete statues should be left to dry for at least 24 hours in a warm, dry area. If possible, choose a sunny day so the paint cures evenly—nothing beats a bit of natural warmth to help things set! If the weather isn’t cooperating (think rain, cold snaps, or heavy dew), bring your statue indoors to a well-ventilated and warm space, like a garage or laundry room. Keep moisture and chill at bay, as these can interfere with the drying process and your paint job’s durability. Patience here pays off—allowing proper drying ensures your hard work lasts for seasons to come.

To keep your statue in top condition, finish by applying a concrete sealer. Resealing every couple of years helps protect against weathering and fading. (Brands like Direct Colors offer reliable sealers and acid stains for added durability and color options.)

For a quick and attractive finish, try the dry brushing technique: start with a solid black base coat, let it dry completely, then lightly brush a highlight color across the raised areas. This method enhances fine details and gives your statue a professional, aged look with minimal effort.

Whether you’re painting garden statues, projects made from stepping stone molds, or decorative pieces created with concrete molds, these same painting and sealing methods will keep your work looking vibrant and long-lasting.

How to Care for Concrete Statues in Cold or Rainy Weather

Concrete statues may look tough, but they still need a little help during harsh weather. Since concrete is porous by nature, moisture can seep in—especially through tiny, hairline cracks or around painted areas. When temperatures dip below freezing, that trapped water can freeze and expand, leading to cracks or peeling paint over time. To keep your statues looking great for years, it’s best to move them to a sheltered spot when rainy or freezing weather is in the forecast. A garage, basement, garden shed, or even a laundry room works well for storage. Keeping your piece dry not only helps prevent moisture damage, but also preserves the finish and reduces the risk of peeling or flaking paint. If moving larger statues isn’t practical, make sure they’re positioned on well-drained ground and cover them with a breathable tarp during wet spells. Avoid wrapping tightly in plastic, as this can trap moisture inside, doing more harm than good. Regular inspections after storms or cold snaps are also a good habit—wipe off excess water and check for any early signs of damage, so you can act quickly to keep your artwork in top shape.

 
 

Testing Readiness- Curing Process

Before demolding, test the concrete's hardness by pressing firmly with a coin or thumbnail. If you can leave a visible mark, the concrete needs additional curing time. Tips for Success

Following these steps will help you achieve professional-quality concrete castings with clean details and proper structural integrity.

Demolding and Finishing

Thanks to proper release agent application, separating the stone from the mold should be trouble-free. Gently flex the mold at the edges to coax finished stones free. Excessive force should never be required with proper preparation, molds should never be filled all the way to the top.

Inspect unmolded stones for rough spots or excess material at edges. Touch up with a damp sponge or sandpaper while concrete remains workable for a professionally finished look. Apply appropriate sealers for extra longevity and color enhancement, noting that residual release agent may affect sealer adhesion.Coloring and Decorative Finishing Products

With your stone freshly demolded, it's time to consider how you want to add color or artistic flair. There are several reliable options for finishing and coloring concrete:

Iron Oxide Pigments: These powder or liquid additives are mixed directly into wet concrete, offering rich, UV-stable colors that won't fade or flake away. Brands like Solomon Colors and Davis Colors are popular choices for vibrant, consistent hues.

Concrete Paints and Stains: If you prefer to color your stones after they’ve cured, look to specially formulated concrete paints or penetrating stains. These allow you to achieve everything from natural earth tones to bold, modern looks. Water-based and acid-based stains can highlight concrete’s textured details or create luminous variegated effects.

Accent and Specialty Products: Consider using tinted sealers, antiquing washes, or even metallic highlights for a custom appearance. These finishing touches not only personalize your stones, but can also add protective qualities and enhance color depth.

Experimenting with colorants and finishes is a fun way to create one-of-a-kind garden features. Just remember to always test new products on a sample stone, and follow manufacturer guidelines for best results.

Mold Care and Maintenance Proper storage extends mold life significantly. After each use, clean away concrete residue, check for wear, and store molds flat or upright in cool, dry areas. ABS molds will last for years with simple water and mild soap cleaning, avoiding harsh chemicals.

Some commercial molds offer convenient stacking or hanging features, maximizing storage space and preventing unnecessary wear. This maintenance, combined with consistent release agent use, makes DIY stone making sustainably cost-effective long-term.Versatility Beyond Stepping Stones

These concrete molds aren’t limited to just garden paths. Crafty types often repurpose them for hypertufa projects—a lightweight, stone-like material perfect for planters, troughs, and even decorative faux rockery. By adjusting your mix to include peat moss and perlite (think of it as a recipe twist borrowed from British gardening tradition), you can create rustic, weathered effects with the same reliable molds.

Additionally, these molds can double as a canvas for wall plaques or sculptural art. Simply pour a thinner concrete or plaster mix, then embellish with glass beads, mosaic tiles, or paint for unique, one-of-a-kind decorative pieces. This flexibility means your mold collection becomes a toolkit for all sorts of creative, personalized garden features and décor.

Design Possibilities and Creative Applications Today's stepping stone molds serve everyone from minimalists to those who favor intricate European tile patterns or nature-inspired designs. For uniform paths, choose molds that align or interlock perfectly. For organic, storybook looks, Angels explore assorted irregular shapes for more natural appeal.

The versatility of quality molds encourages experimentation with textures, colors, and finishes. Whether creating classic cobblestone paths, modern geometric patterns, or fish and animal shapes, your mold selection fuels creative expression while ensuring durability. Exploring More Garden Art Ideas

Stepping stones are just the beginning—if your creativity is calling for more, there’s a whole world of garden art waiting. Many mold makers also offer designs for plaques, whimsical planter feet, and decorative accents to complement your landscape. Fancy a mosaic path that rivals those found in Barcelona’s Parc Güell or inspired by pebble mosaic traditions from Turkey? You’ll find molds and supplies for those projects, too.

For bird lovers, try casting leaf-shaped birdbaths using large hosta or rhubarb leaves as natural templates—simply apply concrete over an oiled leaf for intricate veining and organic shape. If you prefer a sculpted style, choose molds specifically shaped for shallow baths or whimsical water features.

Want to capture memories? Handprint stones and pet memorials are popular, easy projects—just remember to use safe, non-toxic pigments if children are involved, like the vibrant iron oxides used in art concrete projects. For the artistically inclined, creating wall plaques or hypertufa planters offers a rewarding way to personalize patios and entryways. Hypertufa, a lightweight mix of concrete, peat, and perlite, makes containers that mimic ancient stone—perfect for succulents or ferns.
