Discover the timeless beauty of cracked finishes with this tutorial by Lyonella Cook.
In this detailed guide, you’ll learn how to achieve two distinct aged effects using Crack Patina and Cracked Gesso with Milk Paint.
Whether you want a subtle modern patina or a deeply layered antique finish, these techniques will transform your decorative surfaces into heirloom-quality pieces.
Materials You’ll Need
-
One Step Paint (colors used: Vintage Affliction, Holy Moly, Java, Tuscany in the Summer)
-
Toscana Milk Paint (Southern Gentleman, Amalfi Coast)
-
Gel Stain (Hazel Mahogany)
Tools & Extras:
-
Cotton Rags
-
220 Grit Sandpaper
-
Isopropyl Alcohol (50/50 water mix)
-
White Vinegar (optional for cracking effect)
-
Heat Gun or Hair Dryer
Technique 1: Crack Patina Finish
Step 1: Prep the Surface
Start with a raw wood panel and clean thoroughly using Clean Slate. Wipe dry with a cotton cloth. If desired, stain the panel with Hazel Mahogany Gel Stain to add warmth underneath the paint.
Step 2: Apply Crack Patina
Apply Crack Patina in a single direction with a chip brush. For larger cracks, apply thick and full-strength. For finer cracks, dilute slightly with water. Let the Crack Patina dry until tacky (usually 1 hour or more depending on humidity).
Step 3: Add One Step Paint
Apply your topcoat (e.g., Vintage Affliction) in the same direction you applied the Crack Patina. Avoid overbrushing to prevent disturbing the cracking process. Cracks will begin to appear as the paint dries.
Step 4: Add Contrast with Additional Colors
Accent areas with bold complementary colors like Holy Moly or Java. Use your fingers or cloth to subtly lift the paint and guide the crackle effect along curves and carvings.
Step 5: Seal the Finish
After it fully dries, seal with Matte Sealer or a light coat of Spray Shellac. This step stabilizes the cracks.
Step 6: Enhance with Gel Stain or Wax
Apply a very diluted Gel Stain to highlight the cracks. Finish with Light Wax, and optionally Dark Wax around edges for depth. Add Dust of Ages for an authentic antique feel.
Technique 2: Cracked Gesso with Milk Paint
Step 1: Mix and Apply Cracked Gesso
Prepare two gesso mixtures:
-
Thick (sour cream consistency)
-
Thin (heavy cream consistency)
Apply one to two coats of gesso depending on the texture desired. Let each layer dry.
Step 2: Introduce a Chemical Reaction
Spray surface with a 50/50 mix of isopropyl alcohol and water (or vinegar for an alternate effect). Use a heat gun to expedite drying and initiate cracking.
Step 3: Apply Toscana Milk Paint
Use Southern Gentleman + Amalfi Coast for a blue base. Thin your milk paint to a watercolor-like consistency. Apply over the gessoed panel. For maximum effect, add a contrasting yellow topcoat such as Tuscany in the Summer.
Step 4: Speed Up the Crack with Heat
Use a heat gun over the painted surface to accelerate drying and cracking. Cracks will develop based on the thickness and moisture levels of the layers.
Step 5: Build Layers
Repeat the gesso and milk paint process with additional colors if desired. Vary directions of application to introduce visual interest.
Step 6: Seal & Embellish
Once your final crackle has developed and fully dried, seal using Matte Sealer. Add waxes and Dust of Ages to bring out the textures.
Finishing Tips
-
Always let layers dry fully to avoid failure.
