Creating DIY Plaster Dipped Flowers Art Project

Before you can start casting the cement blossoms, you need to prepare your work surface and make sure you have the right cement materials. Here are a few key steps:

Choose and Prepare the Canvas

Select your preferred coarse size and prime it with gesso to create a textured surface the cement can adhere. For this project, I’m using a standard 8″ x 10″ coarse board primed with two coats of white gesso.

Mix the Plaster of Paris

In a bowl, combine cement of Paris powder with water, following package instructions to create a smooth consistency similar to pancake batter. The exact ratio can vary, but generally use 1 part powder to 2 parts water.

Use Quick-set Plaster for Best Results

Opt for a quick-set cement formula that will harden in 30 minutes. This allows you to work swiftly when molding the cement blossoms before it dries.

Add Alginate to Make Flexible Molds

Mix a small amount of alginate putty into the cement to create more flexible molds. This prevents cracking and makes it easier to remove the delicate cement blossoms after casting them.

With your cement mixed and coarse prepped, you’re ready to create molds and cast gorgeous cement blossoms like black plaster wall art for modern interiors!

Crafting Plaster Molds for the Flowers

To form the cement blossoms, you’ll first need to make molds using real blossoms as models. Here’s how to do it:

Choose Flowers and Remove Stems

Select an assortment of fake blossoms in the varieties and colors you want. Carefully use scissors to remove the stems so just the blossoms remain.

Cover Flowers in Plaster Bandages

Dip strips of cement bandages in water and use them to cover each blossom, pressing gently to capture the details. Let them fully dry overnight.

Mix Flexible Plaster for Casting

In your bowl, combine 2 cups cement of Paris, 1 cup water, and 1 tbsp alginate powder. Mix well until smooth.

Brush Molds with Petroleum Jelly

Before casting, coat the dried cement bandage molds with petroleum jelly. This helps separate the casted blossoms later.

Pour Plaster into Molds

Holding the stem end closed, slowly pour your prepared cement into each mold to encase the blossoms. Tap gently to remove air bubbles.

Let Flowers Dry Completely

Allow the cement-filled molds to sit undisturbed overnight so the blossoms can fully harden and cure before removing them.

Attaching the Flowers to the Canvas Plaster of Paris

Once the cement blossoms have dried in their molds, it’s time to cautiously remove them and attach wire stems so they’re ready to arrange on your coarse.

Carefully Remove Flowers from Molds

Start by gently flexing the cement mold to loosen the casted floral inside. Slowly peel away the mold, handling the floral gently to avoid breaking delicate petals.

Trim Excess Plaster if Needed

Use a craft knife to gently trim away any excess cement or imperfections so each floral has a smooth, refined shape.

Attach Stems Made of Floral Wire

Cut lengths of floral wire and use hot glue to attach a “stem” to the bottom of each cement blossom. Bend or curl the wire to adjust the shape.

Let Flowers Dry Fully Before Arranging

Allow the newly formed cement blossoms to dry another 24 hours so the bases are hardened before you arrange and attach them to the coarse.

Affixing the Flowers to the Canvas Surface

Once your handcrafted cement blossoms are prepped, it’s time to position them on the coarse background. Use this method to arrange and adhere to them artfully:

Apply Adhesive to the Back of Each Flower

Use a glue gun or strong adhesive like E6000 to cover the wire stem and base of each floral. This will securely attach them to the coarse surface.

Arrange and Position Flowers on Canvas

Referencing a real floral arrangement, play with positioning the cement blossoms on your coarse crumb until you’re happy with the layout of your sense of art wall decor.

Press Flowers in Place Until the Adhesive Sets

Once arranged, gently press each floral in place while applying firm pressure, holding for 30-60 seconds as the adhesive sets.

Allow Time for a Strong Bond Before Painting

Let the cement blossoms cure on the coarse for another 24 hours to fully adhere before moving on to painting your artwork like boho-inspired plaster wall decor.

Flower Painting Instructions with Acrylic Paints

Once your blossoms are securely attached, add color, depth, and detail with acrylic paints to really make your cement floral composition pop.

Choose Complementary Paint Colors

Select acrylic paint colors that complement each other and represent the floral varieties in your arrangement. Mix colors to create custom shades.

Paint Each Flower Realistically

Use small brushes to delicately apply paint to each floral. Try to recreate natural color variations with highlights and shadows for a realistic look.

Define Details with Paint

Add veins on leaves, flecks on petals, pale colors inside blossoms, and other details with paint to add depth and dimension.

Deepen Shadows Under Flowers

Paint the coarse darker under each blossom to make the blossoms appear more three-dimensional and lifelike.

Seal Paint with Varnish When Done

Once you finish painting, spray the entire coarse with a clear acrylic sealing spray. This protects and preserves the art.

Finishing and Drying the Framed Plaster Casted Artwork

For the final step, frame your artistic coarse to complete your unique floral focal piece and get ready to display it.

Allow Paint to Dry Completely

Give the acrylic paint plenty of time to fully cure before framing, at least 24-48 hours.

Insert Canvas into Frame of Choice

Slide your painted artwork into the frame, securing it in place with provided hardware or frame clips.

Find the Perfect Spot to Hang Your Flower Art

Look for a prime spot in your home to mount your finished framed floral coarse – above a bed or sofa, in a hallway, or anywhere that needs a pop of art.

Using a strong adhesive like E6000 or a hot glue gun works well to firmly adhere the cement blossoms by their wire stems to the coarse. Apply a generous amount and hold in place 30-60 seconds.

Acrylic craft paints work wonderfully for adding vivid color to cement. They bond well and provide excellent coverage. Use small brushes and thin layers of paint to add details.
