Laying Cork on Concrete Subfloor

Preparation of Concrete Surface

  1. Clean Thoroughly: Sweep or vacuum to remove debris and dust. Wash with a concrete cleaner and let it dry completely to avoid moisture issues.
  2. Inspect and Repair: Check for cracks, holes, or imperfections. Fill them with a concrete repair compound to ensure a smooth and level surface.
  3. Level the Surface: Ensure the concrete is smooth and level.
  4. Apply Primer: Use a primer designed for cork flooring. Apply it evenly with a roller or brush and let it dry completely.
  5. Dry Surface: Ensure the concrete is completely dry before applying the primer and adhesive.
  6. Quality Primer: Choose a primer specifically for cork flooring to ensure proper adhesion.

Choosing the Right Cork Tiles

  1. Quality: Opt for high-quality cork tiles that are durable and have a good finish.
  2. Thickness: Choose tiles with appropriate thickness for comfort and insulation.

Laying the Tiles

  1. Acclimate Tiles: Let the cork tiles acclimate to the room temperature for at least 48 hours.
  2. Apply Adhesive: Use a suitable adhesive for cork tiles.
  3. Lay Tiles: Start from the centre and work your way outwards, pressing firmly.

Moisture and Cork Flooring

Susceptibility to Moisture

  • Porous Material: Cork can absorb moisture, leading to swelling and warping.
  • Subfloor Preparation: Ensure the subfloor is dry and free of moisture before installation.

Preventive Measures

  • Moisture Barrier: Use a moisture barrier to protect the cork flooring. Floating floors not glue down tiles.
  • Avoid High-Humidity Areas: Not recommended for bathrooms or basements.

Proper Installation and Maintenance

  • Minimize Moisture Effects: Proper installation and regular maintenance can help mitigate moisture-related issues.

Key Points to Remember

  • Dry Subfloor: Crucial for preventing moisture absorption.
  • Regular Maintenance: Helps ensure the longevity of co
