Jointer Des Couvertines Proprement : La Méthode PRO 💪

Introduction

This tutorial provides a step-by-step guide on how to properly joint wall coping (also known as "couvertines" or "chaperons") for a clean and durable finish. The techniques and materials outlined here will help you achieve a professional-quality result.

Step 1: Verify the Condition of the Copings

• Inspect the covered areas for any damage or deterioration.
• Look for cracks, chips, or loose sections that may need repair.
• Ensure the surface is clean and free of debris before proceeding.

Step 2: Prepare the Copings Before Jointing

• Use a curved trowel to smooth out any rough edges on the copings.
• Sand the surfaces with P80 sandpaper to create a better bonding area.
• Clean the dust and debris from sanding to ensure proper adhesion.

Step 3: Apply a Bonding Resin

• Choose a suitable bonding resin, like Sika's resin.
• Use a brush to apply a thin layer of the resin to the coping surfaces.
• Allow the resin to cure as per the manufacturer's instructions.

Step 4: Gather and Prepare the Joint Mortar

• Assemble the necessary tools, including a mixing bucket and trowels.
• Prepare the joint mortar according to package instructions, ensuring a smooth and workable consistency.

Step 5: Apply the Joint Mortar

• Using a trowel, apply the joint mortar into the gaps between the copings.
• Ensure to fill the joints completely to prevent water infiltration.
• Smooth the surface of the mortar for a clean finish.

Step 6: Apply a Second Pass of Joint Mortar

• Once the first layer has set, apply a second layer of joint mortar for added strength.
• Focus on areas that may have settled or need more fill.
• Smooth again for a uniform appearance.

Step 7: Clean the Joints and Protect the Copings

• Use a damp sponge to clean any excess mortar from the surface of the copings.
• Apply masking tape around the edges to protect the finished surface.
• Allow the joints to cure completely as per the product instructions.

Step 8: Test the High-Pressure Cleaner After Three Weeks

• After three weeks, test the durability of the joints using a high-pressure cleaner set at 110 bar.
• Check for any signs of failure or areas that may need touch-ups.

Conclusion

By following these steps, you can achieve a professional finish on your coping joints. Proper preparation and application are key to ensuring durability and a clean aesthetic. After completing the project, consider regular maintenance to keep your copings in top condition.
