How to Make Jaw-Dropping DIY Dollar Tree Faux Slate Stepping Stones for Under $10!

Before we dive into the ‘how-to,’ let’s look at the ‘why.’ Real slate is beautiful because of its natural layers and deep, earthy tones. However, it is heavy, expensive, and difficult to cut. Our DIY version uses a concrete base with a textured finish that provides the same weight and durability but at a fraction of the cost. By using a specific molding technique, we can replicate the ‘cleft’ surface that gives slate its character. This project is perfect for those who want a sophisticated, rugged look without the high-end price tag.

Why the Dollar Tree?

The secret weapon in this project is the Dollar Tree Pizza Pan or the Plastic Serving Tray. These serve as our molds. They are the perfect diameter for a standard stepping stone, and because they are flexible plastic or thin metal, the cured concrete pops right out. We are also going to source our mixing tools and even some of our texturing materials from the same aisles, keeping our total investment incredibly low.

To keep this project under the $10 mark, we need to be strategic. You likely already have some of these items in your garage, but if not, the Dollar Tree and a quick stop at a hardware store will cover the rest. Remember, the goal is rugged elegance, so don’t be afraid to get your hands dirty.

Budget Mantra: A dollar saved is a dollar earned, but a dollar upcycled is a masterpiece created.

A Note on Safety

Always wear a dust mask and heavy-duty rubber gloves when mixing concrete. The alkaline nature of cement can irritate the skin and the dust is not something you want in your lungs. Work in a well-ventilated area, preferably outdoors.

The key to a convincing faux slate is the texture. Real slate is formed in layers, and when it is split, it creates a ‘cleft’ surface. We are going to mimic this using a slightly thicker concrete mix and a piece of crumpled plastic wrap or a textured sponge. You don’t want a smooth, sidewalk-like finish; you want peaks and valleys.

• Step 1: Prep the Mold. Liberally coat your Dollar Tree pizza pan with cooking spray. This is your release agent. If you skip this, your stone will stay in the pan forever.
• Step 2: The Mix. In a bucket, combine your concrete and water. Aim for a consistency similar to thick peanut butter. If it is too runny, the texture won’t hold. If it is too dry, it will crumble.
• Step 3: The Pour. Fill the pan about 1.5 inches deep. Tap the sides of the pan vigorously for 60 seconds to release air bubbles—this ensures the stone doesn’t have unsightly ‘Swiss cheese’ holes on the surface.
• Step 4: Creating the Cleft. Take a piece of crumpled plastic wrap and press it into the wet surface of the concrete. Gently pull it up to create ridges. Alternatively, use a coarse sponge to ‘dab’ the surface, pulling the cement up into small peaks.

Once your stones have cured for at least 24 to 48 hours, pop them out of the molds. They will be a light, boring grey. This is where the magic happens. We are going to use a ‘dry brush’ and ‘washing’ technique to give them the deep, multi-tonal look of charcoal slate.

The Layering Process

1. The Base Wash: Mix your black acrylic paint with water (50/50 ratio). Brush this over the entire stone, letting it settle into the deep crevices of the texture you created. Let it dry for 10 minutes.
2. The Highlight: Take a small amount of undiluted grey or white paint on a dry sponge. Lightly hit only the high points of the texture. This creates the ‘shimmer’ and depth found in natural stone.
3. The Earth Tone (Optional): For a more weathered look, add a tiny ‘wash’ of burnt umber or rust-colored paint in small patches to mimic iron deposits.

Pro Tip: To make these stones last through rain and snow, apply a coat of clear matte outdoor sealer. It protects the paint and gives the stone a slightly damp, ‘high-end’ look that makes the colors pop.

You’ve made your stones; now you need to set them. A rugged path shouldn’t just sit on top of the grass; it needs to be integrated into the landscape. This ensures safety and longevity.

• Mark Your Path: Lay the stones out on the grass to find the perfect stride length. Usually, 20-24 inches from the center of one stone to the next is ideal.
• Dig In: Trace around each stone with a trowel. Remove the sod and about 2 inches of soil.
• Leveling: Add a half-inch of sand or fine gravel into the hole. This prevents the stone from shifting or cracking when you step on it.
• Set and Fill: Place the stone in the hole, ensuring it is flush with the ground level (this makes mowing over them a breeze). Fill the gaps with pea gravel, moss, or mulch for a professional finish.
