The Rise of Industrial DIY
Cement is no longer confined to sidewalks and foundations. Over the last decade, it has emerged as a premier medium for modern home decor.
The raw, industrial aesthetic of cement pairs perfectly with minimalist interior design. Because the raw materials are highly affordable, crafters are turning fifty-pound bags of cement into high-end housewares.
Creating unique products from this construction staple requires little more than water, a mixing container, and a sense of imagination.
Choosing the Right Mix
Not all hardware store bags are created equal. The distinction between cement, concrete, and mortar dictates the final look of a project.
Portland cement is the binding agent used in concrete. When mixed purely with water, it creates a very smooth, refined finish ideal for small crafts.
Standard concrete includes gravel and sand aggregates. This yields a rougher, textured finish and is better suited for heavy-duty projects like garden benches or outdoor fire pits. For delicate tabletop items, a fine-finish mortar or specialized craft cement works best.
Mastering the Molds
The secret to any successful cement project lies in the mold. The liquid mixture takes the exact shape and texture of whatever contains it.
Silicone baking molds are heavily favored by crafters. They offer high flexibility, meaning the cured cement can be popped out easily without breaking the mold or the piece.
Household recycling bins are also treasure troves for cement molds. Empty milk cartons, plastic soda bottles, and yogurt containers make excellent casting vessels. Cardboard can even be taped into custom geometric shapes, provided the inside is lined with packaging tape to prevent the water from breaking down the paper.
Regardless of the mold type, applying a release agent is mandatory. A light coating of mineral oil or standard cooking spray prevents the cement from bonding permanently to the container.
Popular Cement Projects
The versatility of the medium allows for a massive variety of functional art pieces.
- Succulent Planters: Small, geometric planters are the most common entry point for cement crafting. By nesting a smaller cup inside a larger container filled with cement, crafters create a perfect void for soil and small plants.
- Minimalist Coasters: Shallow, round silicone molds yield sleek drink coasters. Crafters often attach adhesive cork pads to the bottom to protect wooden furniture from scratches.
- Candle Holders: Pushing a standard taper candle or a tealight into wet cement creates an exact, custom-fit holder. Once cured, the heavy base prevents the candle from tipping over.
- Bookends: Pouring concrete into heavy-duty cardboard letters or distinct geometric shapes results in substantial, functional desk accessories.
The Process: Pouring and Curing
Mixing cement is a race against the clock. The powder should be slowly added to water until the mixture reaches the consistency of thick pancake batter.
Wearing a respirator or high-quality dust mask is non-negotiable during this step. Inhaling dry cement powder poses severe respiratory risks.
Once poured, the most critical step is releasing trapped air. Vibrating the mold by tapping it repeatedly against the workbench forces air bubbles to the surface. Skipping this step results in a pockmarked, weak final product.
Patience dictates the rest of the process. While cement may feel hard to the touch after 24 hours, it requires at least 48 to 72 hours to cure fully before it should be removed from a mold.
Finishing Techniques
Freshly demolded cement often has sharp edges or minor surface imperfections. A medium-grit sandpaper makes quick work of smoothing the surface.
Cement is naturally highly porous. If a planter is meant to hold water, or a coaster is meant to catch condensation, the piece must be sealed. A clear masonry sealer or water-based polyurethane protects the piece from moisture damage.
To soften the brutalist aesthetic, many crafters incorporate color. Masking off half of a cement vase and applying a stark white or metallic gold spray paint creates a striking visual contrast that elevates the raw material into a refined piece of decor.
