Setseal CR300

Highly concentrated water based paraffin dispersion concrete curing compound

Setseal CR300 is a high solids water based wax emulsion curing compound formulated from selected materials to form a low viscosity curing compound with outstanding moisture retention characteristics.

Setseal CR300 is supplied as clear and white pigmented colors, the clear color is a white liquid, which forms a wet white film when applied to concrete surfaces and then dries to form a transparent film. The white pigment color is a white milky liquid, which forms a white film after drying and reflects 65 - 80% of the sunlight providing the recommended coverage has been maintained.

  • Helps achieving concrete desired strengths.
  • Minimizes potential surface cracking and shrinkage.
  • Promotes a harder dust free surface.
  • Single component.
  • Can be spray applied to reduce labor cost.

Setseal CR300 is used mainly for newly cast concrete and cementitious surfaces especially in exterior projects, to retain sufficient moisture and ensure full hydration of the cement.

Typical application areas include:

  • Runways and roads.
  • Roof decks.
  • Retaining walls.
  • Irrigation canals.
  • Concrete floors.
  • Concrete tanks.

The recommended coverage rate is 200 ft²/ gal (4.9m²/litre).


Setseal CR300 is available in 5 gal (18.9 litre pails), 55 gal (208.2 litre drums) and 275 gal (1,041 litre totes).


Store in a dry area out of direct sunlight between 41°F and 95°F (5°C and 35°C). Setseal CR300 has a shelf life of 12 months from date of manufacture for the clear version, and 9 months for the pigmented, if stored in proper conditions in un-opened drums. The effectiveness of this product may be adversely affected if these conditions are exceeded and DCP Technical Department should be contacted for advice.
