Here's a simple step-by-step guide for using ACTFLEX 400 to fix leaking tiled areas:

  1. Ensure Surface is Dry: Allow the surface to completely dry and be free from moisture.
  2. Remove Silicone: If present, remove any silicone from corners and penetrations.
  3. Apply Clear MS Sealant: Use a Clear MS Sealant like Soudal TREX Crystal on all corners and any missing grout joints.
  4. Dilute ACTFLEX 400: Dilute ACTFLEX 400 with 50% water.
  5. Apply Thin Coats: Apply three thin coats of the diluted ACTFLEX 400 to the tiled surface.
  6. Form Clear Waterproofing Barrier: Allow the coats to dry to form a clear waterproofing barrier.
  7. Enjoy Leak-Free Surfaces: Once dry, enjoy leak-free balconies or bathrooms for years to come.

Following these simple steps will help you effectively seal and waterproof your tiled areas using ACTFLEX 400.
