Setseal AW309

Multipurpose water based acrylic, concrete curing compound

Setseal AW309 is a single component, acrylic resin based curing compound designed to impregnate concrete surfaces combining the benefits of a curing compound and hardener.

Setseal AW309 is designed to overcome drawbacks of many commonly used curing membranes that tend to provide a limited service life following the curing period of new concrete. It has good abrasion resistance and is compatible with several types of coatings.

  • Recoatable.
  • Non-degradable, single component.
  • Enhanced concrete durability.
  • Increases the surface abrasion.
  • UV resistance.
  • Helps achieve concrete desired strengths.
  • Minimizes potential surface cracking and shrinkage.
  • Promotes a harder dust-free surface.
  • Can be spray applied to reduce labor cost.
  • Non toxic.

Setseal AW309 is mainly used for newly cast concrete and cementitious surfaces that contain GGBFS, PFA, microsilica, dry shake hardeners or limestone to retain sufficient moisture to ensure full hydration of the cement.
Typical application areas include:

  • High rise construction to eliminate water curing.
  • Runways and roads.
  • Roof decks.
  • Retaining walls.
  • Irrigation canals.
  • General floor slab and columns.

The recommended coverage rate is 200 ft ²/gal (4.9 m²/liter) applied in one coat.


Setseal AW309 is available in 5 gal (18.9 ltr) pails, 55 gal (208.2 ltr) drums and 275 (1,041 ltr) totes.


Store in a dry area out of direct sunlight at temperatures between 41°F and 95°F (5°C and 35°C).
Setseal AW309 has a shelf life of 12 months from date of manufacture 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.


Setseal AW309 complies with AASHTO M-148 and ASTM C309 , Type I and II, Class A and B.
