Gather the Right Supplies for Plaster Cast Wall Art

- Plaster of Paris – The base material that will harden into the finished piece. Look for bags labeled “plaster” at any hardware store or online.
- Molds – Choose flexible molds like silicone to easily remove the finished plaster piece. Look for interesting shapes like circles, waves, abstract shapes, etc. Or make your own molds.
- Mixing container – A bucket, pitcher, or large bowl for mixing up the plaster.
- Stir sticks – Popsicle sticks or paint stirrers work well.
- Water – To mix up the plaster.
- Acrylic paints or stains – For adding color after the plaster has dried.
- Sealant (optional) – An acrylic sealant can be applied for added protection.
Follow the Step-by-Step Plaster Cast Process
Creating plaster wall art Canada takes some trial and error, but following these basic steps will set you up for success:
- Prepare the mold. Apply a thin layer of vegetable oil or petroleum jelly so the plaster won’t stick.
- Mix the plaster. Pour the plaster powder into your mixing container. Add water little by little, stirring continuously to avoid clumps. Stop adding water when the mixture reaches a thick, smooth consistency.
- Pour the plaster. Carefully pour the plaster into the greased mold, filling it about 2/3 full. Gently tap the mold to release air bubbles. Insert any objects for patterns now if desired.
- Allow plaster to set. Drying time depends on plaster thickness, but expect at least 2 hours. Don’t disturb the mold during this time.
- Unmold the plaster. Once completely dry, flex the mold gently to pop out the plaster piece. Trim any rough edges with a utility knife or sandpaper.
- Add color. Brush on acrylic paints or use a sponge for stippling effects. Consider layering colors for added dimension.
- Seal the piece (optional). Use an acrylic sealant if you’d like a glossy finish and added protection. Allow sealant to fully dry before hanging.
- Mount on the wall. Use strong adhesives like construction adhesive or epoxy to affix your plaster art to the wall securely. Allow adhesive to cure fully before releasing.
Get Creative with Unique Plaster Textures
One of the best parts of making homemade large plaster wall art ideas is experimenting with textures. Here are some of my favorite techniques for adding interest:
- Press flowers, leaves, ferns, or other natural objects into the plaster while still wet (see step-by-step guide for plaster floral art). Remove them after the plaster dries to reveal beautiful imprints.
- Use burlap, lace or other fabrics to line your mold before pouring in plaster. The texture will transfer.
- Add sand to your plaster mixture for a gritty, stone-like look.
- Imprint designs by pressing rubber stamps, cookie cutters, plastic meshes, bubble wrap or other items into the wet plaster.
- Carve patterns like stripes, circles or squiggles into the semi-dry plaster using clay tools or kitchen utensils.
The options are endless! Layer lines, patterns and textures for even more visual impact.
Troubleshooting Common Plaster Wall Art Problems
Like any DIY project, you may encounter some hiccups with your plaster wall art. Here are some common issues and how to avoid them:
|Plaster won’t release from the mold
|Ensure the mold is greased well first. Tap firmly on the sides and flex the mold to help release the plaster.
|Air bubbles in the plaster leave holes or weak spots
|Gently tap the mold while the plaster is wet to release the bubbles before they form.
|Plaster dries too fast or too slow
|Adjust the water amount as needed to get the ideal smooth, thick consistency.
