    Field of application

    • For professional users only
    • Primer for chemically resistant systems
    • Sealer for chemically resistant systems
    • Top seal for blinding layers in chemically resistant systems
    • Ideal for environments such as the food, beverage, engineering and chemical industries
    • Ideal for coving, plinths and bases, drain linings and bunds
    • For use by professionals


    • High durability
    • High abrasion resistance
    • High chemical resistance
    • Preparation
      • Substrate requirements

        Ideal ambient and substrate temperature range is 15 - 25 °C. Localized heating or cooling equipment may be required outside this range to achieve ideal temperature conditions. The aggregate can be stored in a cool area (or warm area in the case of low ambient temperature) in order to control product temperature and working life. The substrate and uncured floor must be kept at least 3 °C above the dew point to reduce the risk of condensation or blooming on the surface, from before priming to at least 48 hours after application.

      • Preparations

        Inadequate preparation will lead to loss of adhesion and failure. Substrates should be clean, dry, sound and free of surface laitance.

    • Working tools / cleaning
      • Regular cleaning is essential to enhance and maintain the life expectancy and appearance of the product. Crete WR can be easily cleaned using industry standard cleaning chemicals and techniques, especially where sealed using Crete TF. Consult your cleaning chemical and equipment supplier for more information.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Store off the ground in un-opened packs in a dry store, under cover between 10°C and 30°C out of direct sunlight. Protect from frost.

        Resin and hardener components: 12 months

        Aggregate component: 6 months

    • Usage
      • Typically 2 - 9 mm (vertically 4 mm maximum).
        Approximately 2 kg/m² per mm thickness when applied flat.

    • Application examples
      • Priming

        Crete WR should be applied into tacky Epoxy ST 100 (up to 4%) or Epoxy MT 100 (up to 6%) and scatter with Quartz 07/12 whilst wet, 1 kg/m², (typically 45 - 60 minutes after application). If, prior to the application of Crete WR, there are dry patches, a further primer coat is required. If the primer has been left to cure for> 48 hours then the primer surface should be mechanically abraded and the area re-primed.


        Due to the dry nature required of a product designed to be applied vertically, Crete WR shows a lower color strength than flooring materials and color density may vary throughout an installation. Where a closer color match is required or where Crete WR requires sealing, for example, in wet areas or where chemical spillages are likely, Crete TF should be applied within 24 hours of application. See separate technical datasheet. 

    • General information
      • Do not proceed with application if atmospheric relative humidity is, or is anticipated to be, >90% or if the surface temperature is <3 °C above the dew point. Application should not commence when the substrate temperature or the ambient temperature is, or is anticipated to be <5 °C during the application or within the curing period. The design strength of concrete surfaces must be a minimum of 25 MPa compressive strength at 28 days. The manufacture of Remmers Crete WR is a batch process and despite close manufacturing tolerances, colour variation may occur between batches. Products from different batches should not be used on the same surface or surfaces close together. If mixed batches are unavoidable, it is best practice to use the different batches only in areas where the colour cannot be directly compared. Touching up should only be attempted using product from the same batch using the same application methods. Product should be reserved specially for this purpose. It is recommended that touching up is carried out up to a break in the floor or surface.

    • Disposal instructions
      • Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
