Concrete Deck Coat

CPR 820 Concrete Deck Coat is a two pack solvent free resin coating modified to impart toughness, resilience and waterproofing properties to the cured film. The abrasion and impact resistance, together with the low temperature flexibility and excellent adhesion to concrete, make CPR 820 an ideal material for use as a membrane subjected to vehicular traffic. By broadcasting a layer of Quartz or Aluminium Oxide between coats a slip or skid-resistant surface profile can be achieved.

Typical Properties

  • Tough and hardwearing
  • Flexible
  • Excellent abrasion and impact resistance
  • Proven chemical resistance
  • Low odour during application
  • Range of Colours
  • Good water and weathering resistance
  • Non-slip or non-skid finish available

Directions for Use

Surface Preparation 

  • All surfaces should be sound, clean, and free from dust, dirt, laitance, oil and other contaminants.
  • All laitance must be removed by vacuum grit blasting, ensuring that any residual dust is removed prior to coating application.
  • New concrete surfaces must be a minimum of 21 days old and/or have a residual moisture content below 6%.
  • Steel substrates shall be grit blasted to Sa2.5 Swedish standard.


  • A primer coat of CPR 401 – Concrete Primer – Epoxy WB is recommended on concrete substrates.
  • Apply the CPR 401 Primer at a nominal rate of 0.2kg per m² in accordance with the product data sheet instructions.
  • Allow the milky colour of the primer to disappear before overcoating. This will typically be between 1-4 hours, depending on temperature and ventilation conditions.
  • A primer coat of CPR 410 – Metal Primer – Epoxy WB is recommended on steel substrates. (Please refer to product data sheet for additional information).


  • Pour the contents of the CURING AGENT container into the BASE container and thoroughly mix, preferably by mechanical means, until a uniform colour is achieved.


  • Apply by brush or roller at a nominal rate of 0.3kg/m² per coat, with a minimum of 12 hours between coats.
  • Slip-resistant profiles may be achieved by broadcasting an appropriate aggregate on to the first coat whilst wet. The following day any surplus aggregate may be swept from the surface
    before applying a second coat of CPR 820 Concrete Deck Coat.
  • Depending on the size and shape of the aggregate used, the application rate of the second coat of CPR 820 will be 0.4- 0.6kg/m², owing to the increased surface area.

Equipment Cleaning


  • Allow to cure for a minimum of 24 hours @ 20°C prior to light foot traffic access and 48 hours @ 20°C prior to vehicular trafficking.
  • 7 days cure @ 20°C is recommended prior to exposure to chemicals

Storage and Shelf Life

  • Store in dry conditions at temperatures between 10°C and 25°C.
  • CPR 820 – Concrete Deck Coat has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.


  • CPR 820 – Concrete Deck Coat is supplied in 5kg and 15kg packs


  • A 5kg pack is sufficient to coat 8.3m2 of surface with the recommended two coat treatment, providing an overall d.f.t. of 450 microns approx.
  • Coverage will be reduced with slip-resistant systems because of the increased surface area to be covered with the second coat.

Technical Data

  • Pot life @ 20°C: 60 Minutes
  • Colours: Grey, Green, Red as standard (BS4800 or RAL colours can also be supplied)
  • Minimum overcoating interval: 12 hours @ 20°C
  • Maximum overcoating interval: 48 hours @ 20°C
  • Tensile strength: 9MPa (7 days cure @ 20°C)
  • Elongation at break: 85% @ 20°C
  • Chemical resistance: Excellent resistance to dilute acids and alkalis, oil, petrol, diesel, vegetable oils. Specific advice will be provided by our Technical Department.


  • Do not apply to wet or uncured concrete surfaces.
  • Do not apply at temperatures of 3°C or less.

Health and Safety

  • Wear gloves and goggles.
  • Wash off splashes immediately with soap and water.
  • Any eye contamination must be rapidly irrigated with copious amounts of water, and immediate medical attention sought.
