Creating unique home items from simple materials can add a personal touch to your living space. This DIY project uses inexpensive ribbed plastic paint trays, wet cement, and two common garage items to create heavy-duty and stylish ridged slabs. These slabs can function as stepping stones, garden path accents, or decorative pieces. The transformation from simple materials to a robust and aesthetically pleasing product is not only satisfying but also practical, offering durability and a touch of modern design.
These heavy ridged slabs work wonderfully in a contemporary garden setting, offering a stark contrast against green foliage. They can be arranged in a linear pattern to create a path or scattered for a more organic look. Their neutral gray color blends well with both natural and urban environments. For indoor use, consider placing them as stepping stones in a minimalist zen garden or as a base for potted plants to add an industrial edge to your home decor.
Ribbed Cement Slabs

Materials
Plastic ribbed paint trays (12 x 16 inches)
Premixed concrete (enough to fill trays)
Garage item 1: Rubber mallet
Garage item 2: Leveling tool
Directions
1. Start by cleaning the ribbed plastic paint trays to ensure they are free of dust and debris.
2. Mix the premixed concrete according to the package instructions, ensuring it reaches a pourable consistency.
3. Pour the wet cement into each plastic paint tray, filling it to the top of the ribs.
4. Use the rubber mallet to gently tap the sides of the trays to release any air bubbles within the cement.
5. Place the leveling tool on top of the filled trays to ensure the surface is even.
6. Allow the cement to cure in the trays for the recommended time, typically 24-48 hours.
7. Once fully cured, carefully remove the cement slabs from the trays, ensuring they do not crack or chip.

Variations & Tips
For added visual interest, consider embedding colored glass pebbles or small stones into the surface of the wet cement before it cures. This can add a pop of color and texture to the slabs. Alternatively, you can use concrete dye to tint the cement, creating slabs in various shades to match your outdoor decor. Another option is to apply a clear sealant to the cured slabs for enhanced durability and a glossy finish, which can protect them from the elements if used outdoors.
