How to Make Concrete Molds for Pavers: Complete Guide

Making molds for concrete pavers requires the right materials and process. Use silicone or urethane rubber for the mold material. Build a master paver out of wood or clay, then pour rubber over it to make the mold. Understanding this process helps you create custom paver molds.

Step 1: Build Master Paver

Create the master (pattern) first:

• Use wood: Carve or build master from wood
• Or use clay: Shape master from clay
• Exact shape: Master should be exact shape desired
• Smooth finish: Smooth surface creates smooth pavers

Step 2: Choose Mold Material

Two options for molds:

Silicone Rubber

• Flexible
• Easy to use
• Good for simple shapes

Urethane Rubber

• More durable
• Better for complex shapes
• Longer lasting

Step 3: Make the Mold

Create mold from master:

1. Build box: Create box around master
2. Mix rubber: Mix silicone or urethane according to directions
3. Pour over master: Pour rubber over master paver
4. Let cure: Allow rubber to cure
5. Remove master: Remove master, leaving mold

Using the Mold

1. Lubricate mold: Apply release agent
2. Fill with concrete: Fill mold with concrete mix
3. Vibrate: Tap or vibrate to consolidate
4. Remove paver: Remove paver when set

The Bottom Line

Make concrete paver molds using silicone or urethane rubber. Build a master paver from wood or clay first, then pour rubber over it to create the mold. The master determines the final paver shape, and rubber molds allow easy release and reuse. With a good master and proper mold, you can create custom pavers.
