How to use
  • Ensure that the surface to be bonded is clean, dry, and free from any contaminants such as dust, oil, or grease. Remove any old adhesive or loose material from the surface.
  • Mix the contents of the Ceresit CT83 Strong Fix Adhesive Mortar bag with water according to the manufacturer's instructions. Typically, this involves adding the recommended amount of water to a clean container and gradually adding the powder while mixing until a smooth, lump-free consistency is achieved.
  • Apply the mixed adhesive mortar to the surface using a notched trowel, ensuring an even layer of adhesive is applied. The recommended thickness of the adhesive layer depends on the type and thickness of the insulation board being used.
  • Press the insulation board firmly onto the adhesive mortar, ensuring good contact between the board and the adhesive. Use a roller or a similar tool to remove any air pockets and ensure a uniform bond.
  • Allow the adhesive to cure according to the manufacturer's instructions. The recommended curing time depends on various factors, such as temperature and humidity.
Note: Always follow the manufacturer's instructions and safety guidelines when using Ceresit CT83 Strong Fix Adhesive Mortar. Wear appropriate personal protective equipment, such as gloves and safety glasses, and ensure adequate ventilation during application.
