Application Instructions

  1. 1

    Surface Preparation

    The substrate must be sound, clean, dry, smooth, and level. Oil, grease, rust, dust, dirt, and loose particles must be removed. Damaged or defective areas should be repaired before application. Smooth surfaces such as ceramic, marble, and similar materials should be roughened to improve adhesion. Concrete substrates should be lightly pre-dampened; however, standing water must not be allowed on the surface.

  2. 2

    Mixing

    Gradually add 25 kg of FLEXDER+ to 7.0–7.5 L of clean water in a clean mixing container. Mix using a low-speed mixer until a homogeneous, lump-free consistency is obtained. Allow the mortar to rest for 5–10 minutes, then remix for 1–2 minutes before application.

  3. 3

    Application

    Apply the prepared mortar within its pot life. Place the covering material onto the adhesive within the open time and press firmly to ensure proper adhesion.

Important Notes

  • The application and ambient temperature should be between +5 °C and +35 °C.
  • Do not add water, cement, or any other additives to the prepared mortar.
  • After application, protect the surface from frost, rain, direct sunlight, strong winds, and high temperatures.
  • Take appropriate protective measures against frost at low temperatures and rapid moisture loss at high temperatures.
  • Wait at least 24 hours before applying the grout.
  • Clean the surface with water before the mortar has fully hardened.
  • Clean all tools and equipment with water immediately after use, before the mortar hardens.

Storage and Shelf Life

Store in the original, unopened packaging in a cool, dry place, protected from moisture, frost, and direct sunlight. When stored under appropriate conditions, the shelf life is 12 months from the date of manufacture.

Health and Safety

This product is cement-based and may cause irritation to the skin and eyes. Appropriate personal protective equipment (protective clothing, protective gloves, safety goggles, and a dust mask) should be worn during application. The use of a protective skin cream before starting work is recommended. In case of contact with the eyes, rinse immediately with plenty of clean water and seek medical attention without delay.
