Adding stencils—whether purchased or DIY—lets you create professional-looking patterns and designs with minimal effort. This guide covers everything you need, including tools, paint tips, and techniques for sealed (e.g. treated with concrete wax or sealer making the surface water-resistant) and unsealed planters.

What You’ll Need

Gather the following materials before starting your project:

  • Concrete-friendly paint (acrylic, latex, or masonry paint)

  • Paintbrushes or foam brushes

  • Painter’s tape

  • Sandpaper (80-120 grit)

  • Primer designed for concrete (optional)

  • Stencils (buy or make your own)

  • Sponge or stencil brush

  • Sealer (for durability)

  • Drop cloth or newspaper

  • Cleaning supplies (soap and water)


Step-by-Step Guide to Painting Concrete Planters


1. Clean the Planter

Start by thoroughly cleaning your planter. Use soap and water to remove dirt and debris. Let it dry completely before moving to the next step.


2. Prep the Surface

  • For unsealed planters: Sand the surface lightly to smooth out imperfections and help the paint stick.

  • For sealed planters: Lightly sand to roughen the surface so the paint adheres better.


3. Apply Primer

Priming helps create a smooth base and ensures your paint adheres evenly. Apply a concrete-compatible primer and let it dry completely.


4. Base Coat Painting

Apply a base coat of paint using a foam brush or regular brush. Use thin, even coats to prevent drips, allowing each coat to dry fully before adding the next. Most projects require 2-3 coats.


5. Stencil Application

Stencils are a great way to add patterns or designs to your planter.

  • Buying Stencils: You can purchase ready-made stencils from craft stores or online. Choose designs that match your style, such as geometric patterns, floral motifs, or words like “Grow” or “Bloom.”

  • Making Your Own Stencils: Create DIY stencils using sturdy materials like cardstock, vinyl, or acetate sheets. Cut out your design using a craft knife or cutting machine.


How to Use Stencils:

  1. Position the stencil on the planter and secure it with painter’s tape to prevent movement.

  2. Use a stencil brush or sponge to dab paint gently onto the stencil. Avoid overloading the brush to prevent bleeding.

  3. Carefully remove the stencil while the paint is still wet. Clean the stencil if you plan to reuse it.


6. Seal the Planter

Once the paint is dry, seal the planter with a clear concrete sealer. This step is essential for outdoor planters to protect against weather and fading.

Tips & Tricks for a Professional Finish

  • Use Painter’s Tape: To keep edges clean and prevent paint from bleeding, tape off areas around your stencil.

  • Practice First: Test your stencil design on paper or cardboard before applying it to the planter.

  • Mix and Match Designs: Combine stencils for a layered effect, such as pairing stripes with floral patterns.

  • Weather-Resistant Paints: For outdoor planters, ensure your paint is UV- and water-resistant to extend its life.

  • Add Metallic Accents: Use metallic paints for extra flair, especially on raised stencil designs.


Can You Paint Sealed and Unsealed Concrete Planters?

Yes! Both types can be painted with the right approach:

  • Sealed Planters: Use paint designed for non-porous surfaces, and lightly sand the sealant before painting.

  • Unsealed Planters: These are porous, so primer is recommended to prevent paint from absorbing unevenly.


DIY Stencil Ideas

If you’re making your stencils, try these ideas:

  • Botanical Patterns: Leaves, ferns, or flowers for a garden-inspired look.

  • Geometric Shapes: Triangles, chevrons, or polka dots for a modern aesthetic.

  • Personalised Text: Add your initials, plant names, or phrases like "Fresh Start."

  • Seasonal Themes: Stencils featuring snowflakes, sunbursts, or pumpkins for a festive touch.
