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 colours, the clear colour is a white liquid, which forms a wet white film when applied to concrete surfaces, this dries to form a transparent film. The white pigment colour is a white milky liquid, which forms a white film after drying and reflect 65 - 80% of the sunlight providing the recommended coverage has been maintained.


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
  • Columns tanks

Materials Supplied

Setseal CR300 is available in 5 gal (18.9 litre pails), 55 gal (208.2 litre drums) and 275 gal (1041 litre totes). 


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


Store in a dry area out of direct sunlight between 41°F and 95°F (5°C and 35°C).

Shelf Life

Setseal CR300 has a shelf life of 12 months from date of manufacture for the clear colour, and 9 months for the pigmented colour, if stored in proper conditions in unopened drums.

Application Instructions

Setseal CR300 should be spray applied as soon as possible to the fresh concrete, provided that the surface water has evaporated. Do not apply if bleed water is forming, or is present on the concrete surface.

Stir Setseal CR300 well before use to ensure even pigment dispersion. Setseal CR300 should be spray applied, the spray nozzle should be held approximately 18" (457 mm) from the concrete surface and passed back and forth to ensure complete coverage. Pump pressure should be maintained to give an even, fine spray.

The applied film should be protected from rain for at least 3 hours; care should be taken to ensure that the film is not broken. In case of formed concrete, Setseal CR300 should be applied immediately after de-shuttering. In such a case the concrete surface must be dampened with clean water prior application of Setseal CR300.

Dry surfaces may prevent correct film formation and cause absorption of the Setseal CR300 into the concrete surface, which may lead to staining and difficulty in later degradation and removal.


Setseal CR300 is not classified as a hazardous material. In case of accidental splashes to the eyes, immediately flush with plenty of water and seek medical attention. Suitable protective gloves and goggles should be worn.
