    Field of application

    • For use on floors/walls indoors and outdoors
    • Preparation of bonding grouts, bonding mortars, patch and repair mortars
    • Improvement of screeds, renders and touch-up layers
    • Primer for concretes, cement and anhydrite screeds

    Properties

    • Water-based
    • Improves adhesive bonding
    • Increases compressive strength
    • Increases flexural strength
    • Saponification resistant
    • Preparation
      • Substrate requirements

        The substrate must be clean, solid and free of oils, grease and release agents.

        The substrates may be slightly damp but must not have a film of liquid.

    • Application
      • Application temperature: min. 5 °C max. 25 °C
      • Broom / Trowel / Filling knife
      • Mortar improvement

        Dilute the material with water and mix well (observe the correct mixing ratio).

        Use mixture as mixing water for the mortar.

         

        Adhesive primer

        Dilute the material with water and mix well (observe the correct mixing ratio).

        Apply the mixture evenly over the prepared substrate.

        In the case of highly absorbent substrates, repeat the process within 24 hours if necessary.

         

    • Application instructions
      • Always dilute the material with water.

        Do not let excess material build up on the surface.

        Take appropriate measures to protect adjacent building elements and materials that should not come into contact with the product.

    • Working tools / cleaning
      • Broom / Trowel / Filling knife
      • Wide brush, broom, spatula or trowel

        Clean tools, equipment and splashed material immediately while fresh with V 101.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Shelf-life 24 months
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 24 months.

    • Usage
      • Depending on the application / m²
      • For bonding layers, grouts: approx. 0.1 - 0.2 kg/m²
        For bonding mortar: approx. 1.0 kg on 1 - 2 m², depending on the layer thickness

      • Apply to a large enough trial area to determine the precise amount required.
