Step 2: Build the Mold (Formwork)

Your mold determines the shape and smoothness of your countertop, so precision is key.

How to Make the Mold

1. Use melamine boards, as the smooth surface helps produce a polished finish.

2. Cut boards to create the base and sides of your countertop.

3. Secure the edges using screws.

4. Seal the seams with 100% silicone caulk to prevent leakage.

5. Apply mineral oil to the mold surface to prevent concrete from sticking.

💡 Tip: Ensure your mold is perfectly level—this directly impacts the quality of your finish.

Step 3: Mix & Pour the Concrete

1. Follow the manufacturer’s instructions for your chosen high-strength concrete mix.

2. Mix until smooth and lump-free.

3. Slowly pour the concrete into the mold.

4. Use a trowel to level the surface.

5. Tap the sides with a rubber mallet to release air bubbles.

6. Insert reinforcement mesh or rebar in the middle of the concrete layer.

7. Smooth and level again.

Optional Enhancements

• Add pigment for colour.

• Add glass chips, aggregates, or stones for decorative finishes.

Step 4: Let the Concrete Cure Properly

Concrete curing is one of the most important steps.

Curing Tips

• Leave the mold undisturbed for 48 hours.

• Cover with plastic for moisture retention.

• Let it cure for 7 days before polishing.

• Full cure occurs at 28 days (recommended before sealing).

Step 5: Remove the Mold

Once the countertop is solid:

1. Unscrew and remove the melamine sides.

2. Carefully lift the countertop using two people.

3. Place it on a soft, stable surface for polishing.

Step 6: Polish the Concrete Surface

Polishing gives the countertop its smooth, glossy, and refined appearance.

You’ll Need:

A wet polisher with diamond polishing pads:

• 50 grit (heavy grinding)

• 100 grit

• 200 grit

• 400 grit

• 800 grit

• 1500 grit

• 3000 grit (high-gloss mirror finish)

Polishing Process

1. Start with low-grit pads (50–100) to smooth imperfections.

2. Move up gradually to higher grits.

3. Keep the surface wet throughout the process.

4. Apply densifier after 200–400 grits for extra hardness.

5. Continue polishing until you reach desired shine.

Step 7: Seal the Countertop

Sealing is essential for protecting the concrete from stains, moisture, and scratches.

Types of Sealers:

• Topical Sealers (high shine, good for kitchens)

• Penetrating Sealers (matte finish, natural look)

• Food-Safe Sealers (ideal for kitchen surfaces)

Apply 2–3 coats for best durability.
