Title

Enhance your crack repair projects with our dedicated mortar adhesive, specifically formulated for mending cracks in roofs and floors. It ensures reliability and durability across various construction tasks.

FEATURES

  • Exceptional flexibility and crack tolerance: Built to endure building shifts and settling without fracturing, it provides superior bonding strength and longevity compared to standard cement mortars.

  • Quick-drying formula: Designed to minimize curing times, it sets in as little as 2 hours*. (*Drying durations may differ based on ambient temperature and humidity.)

  • Enhanced flowability: Effectively penetrates into cracks, ensuring complete sealing from the bottom to prevent water leakage, offering thorough protection.

  • Diverse application: Works well on a variety of surfaces, such as walls, floors, bathrooms, metal, wood, and tiles, ideal for resolving cracks in corners, windows, joints, roads, concrete floors, and bathroom tiles.

  • Application instructions:

    • Procedure for addressing shallow cracks:

      1. Clean the surface thoroughly to eliminate dust and loose debris.
      2. Cut the nozzle to match the crack size and inject the adhesive evenly until the crack is filled completely.
    • Procedure for addressing deep cracks:

      1. Prepare the area by removing dust and loose materials.
      2. For deeper cracks, lay down a base layer of cement to reduce material usage.
      3. Deeply inject the adhesive into the crack and smooth out any excess with a spatula.
  • Construction guidelines:

    1. Make sure the workspace is clean and free of dust and oil prior to application.
    2. Utilize the product right after opening to avoid curing that may affect performance.
    3. Curing times may be influenced by climatic conditions; extended periods during colder months are expected.
    4. Post-application, level out any excess adhesive that extrudes from the cracks using a spatula.
    5. Store the product in a cool, dry environment for optimal preservation.
