how to use mapei aquadefense


The Mapei Aquadefense Tanking Kit is a comprehensive solution for waterproofing wet areas in bathrooms, showers, and other spaces. This easy-to-use kit ensures a watertight barrier, preventing moisture penetration and potential damage. Follow these bulleted steps for a successful application:

  1. Gather Necessary Materials:

    • Mapei Aquadefence Tanking Kit
    • Clean mixing container
    • Drill with mixing paddle attachment
    • Paintbrush or roller
    • Utility knife
    • Reinforcement tape often included in kit form, otherwise use Mapei jointing tape
  2. Surface Preparation:

    • Ensure the substrate is clean, dry, and free of any dust or contaminants.
    • Repair any cracks or imperfections in the surface using suitable materials.
  3. Mix the Aquadefense Liquid:

    • Open the Aquadefence Liquid component (Part A) and mix it thoroughly with a drill and mixing paddle until a homogeneous consistency is achieved.
  4. Allow Mixture to Rest:

    • Let the mixed solution rest for a few minutes, allowing it to reach the desired consistency.
  5. Apply the First Coat:

    • Using a paintbrush or roller, apply the first coat of the Aquadefence mixture to the prepared surface. Ensure an even and consistent application, covering the entire area.  You should be looking for a thick coat of the liquid.
  6. Embed Reinforcement Tape:

    • While the first coat is still wet, embed the included Aquadefence reinforcement tape into the applied layer. Smooth out any air bubbles or wrinkles to ensure proper adhesion.
  7. Apply Second Coat:

    • After the reinforcement tape is in place, apply a second coat of the Aquadefence mixture, ensuring complete coverage and a uniform thickness.
  8. Seal Joints and Corners:

    • Pay special attention to joints and corners, applying additional Aquadefence mixture to create a seamless and watertight seal.
  9. Cure and Dry:

    • Allow the applied Aquadefence coating to cure and dry completely before subjecting it to water exposure. Follow the manufacturer’s recommended drying times.
  10. Perform Water Test:

    • Once fully cured, perform a water test to ensure the effectiveness of the Aquadefence Tanking Kit. Check for any signs of water penetration or leaks.

By following these steps, you can effectively use the Mapei Aquadefence Tanking Kit to create a reliable waterproof barrier in wet areas, providing long-lasting protection against moisture-related issues. Always refer to the product’s technical data sheet and follow the manufacturer’s instructions for optimal results.

Ideally you should wait around half an hour between coats.  Again, don’t skimp on the application. You should be looking for a thich coat of tanking to ensure that your shower area will be waterproof.
