Materials Needed for Plaster Flower Wall Art DIY

To start your plaster flower project, you’ll need to gather these basic supplies:

  • Plaster of Paris
  • Disposable plastic cups or bowls
  • Plastic flowers, leaves, ferns or other greenery
  • Petroleum jelly
  • Acrylic paint
  • Paintbrushes
  • Containers for mixing plaster
  • Bucket or tray for pouring leftover plaster
  • Drop cloths
  • Sandpaper
  • Primer and paint
  • Heavy-duty mounting putty or construction adhesive

The plaster, paint, putty, and adhesive are absolute necessities. The rest of the materials can be substituted if needed. For example, you can use silicone molds instead of greenery to create flower shapes and enhance with wall plaques.

Step-by-Step Instructions for DIY Plaster Flowers

Follow these simple steps to craft your own 3D plaster wall art flowers:

Make the Flower Molds

  1. Choose plastic flowers, leaves, or ferns to use as molds. The size and shape are up to you!
  2. Remove any stems or extras so you just have the flower/leaf itself.
  3. Coat the underside (the side that will touch the plaster) with a thin layer of petroleum jelly. This will help release the mold later.

Mix the Plaster

  1. Plan how much plaster you’ll need based on the number and size of molds. Follow the package directions.
  2. Pour measured water into a mixing container first, then gradually add plaster powder while stirring.
  3. Stir vigorously for 2-3 minutes until lump-free. The consistency should be like a thick pancake batter.

Pour the Plaster

  1. Pour a thin layer of plaster into each mold-shaped cup, about 1/4 inch deep.
  2. Place the greenery mold face down onto the plaster. Gently press down.
  3. Slowly pour plaster over the back of the mold, filling the cup.
  4. Tap the cup to help the plaster settle. Smooth the top if needed.
  5. Allow the plaster to set and harden completely, about 30-60 minutes. Longer times are OK.
  6. Once hardened, flex the cup to pop out the flower mold. Peel off any residual greenery.
  7. Repeat for all flowers. Let them finish drying for 6-12 hours.

Add Color and Detail

  1. Lightly sand each flower’s edges if needed to smooth for enhancing your space with colorful plaster wall decor. Wipe away dust.
  2. Paint the flowers and leaves with acrylic paints. Use multiple colors to add detail and depth.
  3. Add lines, dots, or designs for extra dimension. Accent with metallic paints like gold or silver.
  4. Allow the acrylic paint to fully dry before continuing.

Mount the Plaster Flowers

  1. Arrange the painted flowers on the wall in how you want them displayed. Mark spots.
  2. Apply blobs of strong mounting putty or adhesive to the wall where the marks are.
  3. Press the back of each plaster flower into the putty or adhesive. Hold for 30 seconds.
  4. Let the adhesive cure fully per package directions so connections are secure.

Finish the Wall

  1. Fill any cracks or holes in the wall with spackle compound and sand smooth.
  2. Clean the wall then apply a coat of primer and let dry.
  3. Paint the wall your desired background color and allow it to dry fully before hanging other decor.

And that’s it! Now stand back and admire your beautiful, customizable plaster flower art.

Frequently Asked Questions

Acrylic craft paints are ideal for painting plaster flowers. The acrylic formula adheres well to plaster surfaces. Acrylics also come in endless color choices and dry quickly.

Lightly sanding the flower edges with fine grit sandpaper helps smooth any rough spots. Wipe away the dust before painting. Using silicone molds instead of greenery will also result in smoother edges.

It’s best to keep plaster flowers indoors as a wall art piece. When exposed to outdoor conditions over time, plaster can eventually deteriorate. Using sealants could help but won’t prevent damage forever.

You’re not limited to just flowers! Any plastic or silicone mold shaped like leaves, ferns, vines, seashells, or other natural motifs will work. Craft stores offer many template options to push into plaster.

Heavy-duty adhesives like mounting putty or construction adhesive work best. Apply a blob where each flower will hang, then press into place for 30 seconds. Allow to fully cure before decorating around the flowers.

Conclusion

DIY plaster flower wall art makes a lovely decorative statement in any room. With inexpensive materials on hand, you can create botanically inspired works of art.

Use real flowers, leaves, and ferns as molds or craft-store silicone molds for shaping the plaster. Paint with acrylics and attach securely with adhesives on a clean, painted wall.
