DIY Kitchen Island Extension – Step-by-Step

1. Measure Your Kitchen Island Carefully

Start by taking precise measurements of:

• The existing island

• The desired table height

• The depth and width of the extension

📏 Accuracy here ensures stability and comfort later.

2. Build the Legs and Back Support

Create the wooden legs and the rear support structure that will hold the extension firmly against the island.

This structure is key for:

• Weight distribution

• Long-term stability

• Safe everyday use

3. Burn the Wood for Protection

Burning the wood (Shou Sugi Ban technique) helps:

• Protect against moisture

• Increase durability

• Add a unique rustic finish

🔥 Functional and beautiful.

4. Add Decorative Wood Designs

This is where creativity kicks in.Add custom drawings or patterns to the wood to personalize your kitchen island extension.

Every piece becomes unique.

5. Sand and Apply Epoxy Resin (Glow Effect)

Sand the surface thoroughly, then apply epoxy resin, including a glow-in-the-dark effect for a bold and modern touch.

✨ Perfect for evening ambiance and wow-factor.

6. Sand Again for a Perfect Finish

Once the epoxy has cured:

• Sand again to remove imperfections

• Achieve a smooth, professional surface

7. Assemble and Attach to the Kitchen Island

Mount all elements together and securely attach the extension to the island.

🔩 Make sure everything is level, stable, and solid.

Enjoy Your New Kitchen Island Space
