Clean the existing countertop thoroughly, removing any grease, dirt, or loose material. If there are stains or scratches, smooth them out as much as possible. Use a razor blade to remove any existing silicone sealant to ensure the concrete adheres properly.

Step 2: Sand the Countertop

Use coarse sandpaper (60- or 80-grit) to roughen the surface, allowing the concrete to grip better. After sanding, wipe down the countertop with a damp cloth to remove dust and debris.

Step 3: Mix the Concrete

In a mixing bucket, combine Ardex Feather Finish with water at a 2:1 ratio, stirring until it reaches a peanut butter-like consistency. Avoid splashing or overmixing to prevent air bubbles.

Step 4: Apply the First Concrete Layer

Using a trowel, spread the concrete in small sections (about 1’ x 1’). Work from one corner outward, applying an even layer. Use a putty knife to coat the edges and corners, ensuring full coverage.

Step 5: Smooth and Shape the Corners

For rounded corners, mold the concrete with your fingers once it starts to set. Avoid adding water to smooth it, as this can cause discoloration and weaken the surface.

Step 6: Let the Concrete Dry
