Making a Concrete Benchtop from Scratch
Wondering how to make a concrete benchtop but unsure where to start? This versatile and stylish option has become popular for DIY enthusiasts and homeowners alike. Not only does a concrete benchtop add an extraordinary charm to your kitchen island or outdoor space, but it also offers durability and a bespoke aesthetic that’s hard to match.
Understanding the Basics of Concrete Benchtops
When exploring how to make a concrete benchtop, it’s crucial to understand what concrete benchtops are and why they are an increasingly popular choice for modern homes.
What are Concrete Benchtops?
Concrete benchtops, often called concrete countertops or concrete counters, are robust and versatile surfaces made from a mixture of cement, aggregates, and water. Once mixed, the concrete is poured into countertop forms, carefully shaped, and then allowed to cure. This process results in a solid, durable concrete surface tailored to any kitchen design or aesthetic preference.
Key Components of Making Concrete Benchtops
- Concrete Countertop Mix: This is specifically designed for countertops, offering a smoother, more workable consistency than regular concrete.
- Countertop Forms: These are moulds used to shape the concrete. They can be made from materials like melamine or cement board, providing a template for the desired countertop shape.
- Curing Process: The concrete cure is a critical stage where the mixture hardens into a solid form. This process requires patience, as rushing it can lead to weaknesses or cracks in the benchtop.
- Finishing Touches: Once cured, the concrete surface may show signs of excess concrete or imperfections. These are addressed through careful sanding and finishing, ensuring a smooth and even surface.

Material List and Preparation
Making a concrete benchtop requires gathering the suitable materials and tools to enjoy a smooth process and a high-quality finished countertop. Here’s what you need and why each item is essential:
Essential Materials
- Concrete Countertop Mix: Choose a high-quality concrete mix ratio designed explicitly for countertops. This ensures a smoother, more durable finished surface.
- Cement Board: As a base for your casting table, cement boards provide a stable and level surface for the concrete pour.
- Water: Clean water is essential for mixing the concrete. The quantity varies, but typically, you’ll need about 2-3 quarts of water per 80-pound bag of cement mix.
- Rebar or Wire Mesh: These provide internal strength to your countertop, which is especially important for larger designs.
- Countertop Forms: You can use melamine-coated particle board or other materials to create the mould for your countertop. These forms define the shape and size of your finished countertop.
- Mixing Tools: A concrete mixer, a sturdy mixing container, and a mixing paddle are vital for preparing your concrete mix (learn how to mix concrete like a pro with this handy guide).
- Trowels: A steel trowel is vital for smoothing the concrete surface after pouring.
- Edging Tools: For finished countertop edges, use tools that can create square edges or curved edges, depending on your design.
- Duct Tape and Silicone Caulk: These seal the joints of your forms, ensuring the concrete doesn’t leak out.
- Water Sprayer: A sprayer helps add water to the concrete mix and keeps the concrete moist during curing.
- Vibration Tools: These help remove air bubbles from the mix, leading to a denser, more uniform concrete surface.
Preparing the Materials and Workspace
- Preparing the Cement Mix: Follow the manufacturer’s instructions for the proper water-to-cement ratio. It’s necessary to get a consistent, workable mix.
- Building the Mould: Construct the form for your benchtop using the cement board and duct tape to seal all edges. Check if the entire form is well-constructed and sturdy.
- Setting up the Casting Table: Place your mould on a flat and stable casting table. This will be the surface where you pour and cure the concrete.
Why These Materials and Tools?
- Quality of Materials: Selecting suitable materials guarantees your concrete countertops’ longevity and aesthetic appeal.
- Precision in Preparation: Accurate measurement and careful preparation of materials lead to a better-finished product.
- Tools for Ease and Efficiency: The right tools simplify the process and contribute to a smoother, more professional-looking countertop.
With this comprehensive material list and preparation guide, you’re well-equipped to start your journey in how to make a concrete benchtop.
Step-by-Step Guide to Making a Concrete Benchtop
Creating a concrete benchtop involves a series of steps, each crucial to ensuring a quality finish. Here’s a detailed guide on how to make a concrete benchtop:
Step 1: Building the Form
- Design Your Form: Measure and cut the cement board to the desired countertop size. This will serve as the base of your form.
- Assemble the Form: Attach the sides to the base using screws. The height of the sides should match the thickness you want for your countertop.
- Seal the Concrete Formwork: Use silicone caulk and a putty knife to seal all the joints and corners of the form. Cover any screws or rough areas with duct tape for a smooth finish.
Step 2: Mixing the Concrete
- Prepare the Mix: Combine the concrete mix with the recommended quarts of water. You can either whirl it with a mixer or blend it by hand to get that even consistency throughout.
- Add Color or Additives (Optional): If desired, add colour pigments or additives at this stage, mixing thoroughly to ensure even distribution.
Step 3: Pouring the Concrete
- Pour into the Form: Carefully pour the concrete mix into it, ensuring it reaches all corners and edges.
- Remove Air Bubbles: Use a vibration tool or gently tap the sides of the form with a rubber mallet to release any trapped air bubbles.
Step 4: Curing the Concrete
- Let It Set: Give the countertop enough time to harden fully. The setting time varies from 2 to 7 days, depending on the type of mix you’ve used and the surrounding environmental factors.
- Keep It Moist: Use a water sprayer to lightly mist the surface during curing. This helps prevent cracks and ensures even curing.
Step 5: Finishing the Countertop
- Remove the Form: After the concrete has cured, carefully dismantle the form.
- Sand the Surface: Use an orbital sander to smooth the entire surface and edges of the countertop. Be prepared for concrete dust; wear appropriate safety gear.
- Fill Any Imperfections: If there are small holes or imperfections, fill them with a concrete slurry and smooth them with a steel trowel.
- Final Curing: Allow the countertop to cure fully, which usually takes a week, depending on the mix and environmental conditions.
Step 6: Sealing and Installing
- Seal the Countertop: Put on a layer of concrete sealer to safeguard the surface. Doing this is key to preserving your countertop’s look and durability.
- Install the Countertop: Once sealed and fully cured, the countertop can be installed on your cabinet base or desired area.
Why These Steps Matter
- Form Construction: A well-built form ensures your final counter surface’s correct shape and smoothness.
- Concrete Mixing: Proper mixing and consistency are critical to a strong, durable countertop.
- Curing Process: Adequate curing is essential for the concrete’s strength and to prevent cracking.
- Finishing Touches: Sanding and sealing enhance the countertop’s appearance, functionality, and lifespan.
