DIY Concrete Coasters: A Modern Home Accent

Learn to make your own modern concrete coasters! This simple project is perfect for adding a touch of industrial chic to your home.

What You’ll Need

• Concrete Mix: A small bag (around 5 lbs should be plenty).
• Silicone Coaster Molds: You can find these online or at craft stores. A variety of shapes are available.
• Mixing Container: A bucket or large bowl.
• Mixing Tool: A trowel, spoon, or even a sturdy stick.
• Water: Clean tap water.
• Safety Gear: Gloves (concrete mix can be irritating to skin) and a dust mask (especially when working with dry mix).
• Optional: Concrete sealer (to protect the coasters from staining).

Step-by-Step Instructions

Step 1: Mixing the Concrete

Read the instructions on your concrete mix bag carefully. Generally, you'll want to add water to the dry mix gradually, mixing thoroughly until you achieve a consistency similar to thick pancake batter. It should be pourable but not too runny. Avoid adding too much water – excess water weakens the concrete.

Step 2: Pouring the Concrete into Molds

Carefully pour the concrete mixture into the silicone molds. Make sure the molds are level to ensure even coasters. Gently tap the molds to release any trapped air bubbles. This will result in stronger, more even coasters.

Step 3: Demolding and Curing

Allow the concrete to set completely. This usually takes 24-48 hours, but refer to your concrete mix instructions for specific times. Once set, gently remove the coasters from the molds. Curing is critical! Keep the coasters damp for at least a week by covering them with a damp cloth or spraying them with water daily. This helps them gain strength and reduces cracking.

Step 4: Finishing (Optional)

At this point, your coasters are ready to use! However, you can add a few optional finishing touches:

• Sanding: If you want perfectly smooth edges, use fine-grit sandpaper to lightly sand the edges.
• Sealing: Applying a concrete sealer will help protect the coasters from stains and make them easier to clean. Follow the sealer's instructions carefully.

Tips & Tricks

• Experiment with colors: Add concrete dyes to the mix for a pop of color.
• Embed objects: Add small stones, beads, or other decorative elements into the concrete before it sets.
• Don't rush the curing process: Patience is key for strong, durable coasters.
