AT-CURE (AC) is a dual-purpose, water based acrylic clear coating designed for curing and sealing new concrete and sealing existing concrete. When applied over freshly placed concrete Acrylic Concrete Cure and Seal eliminates the need for moist curing and improves the strength and durability of the concrete surface.


AT-CURE (AC) complies with ASTM C 309 Type II Class B

  • Non-degrading, membrane forming resins for freshly or de shuttered concrete, assists in the retention of water during hydration.
  • Resultant film retains sufficient moisture in concrete to ensure full hydration of cement, essential for optimum strength development.
  • Act as a primer for protective coatings.
  • Improve moisture retention in concrete.
  • Prevents rapid water evaporation.
  • Sealer & dust proofer
  • Good abrasion resistant-long protection.
  • Reduces drying shrinkage
  • Reduces the incidence of hair line cracks.
  • High curing efficiency.
  • Eliminates the primary source of abrasion and enhancing durability.


  • As a more effective and economical alternative to separate curing and priming/sealing regimes.
  • Suitable for use on all concrete surfaces.
  • Surfaces subject to finishing treatments.
  • Economical enhancement of concrete flatwork.
  • In high-rise construction to eliminate the requirement for water.


  • The recommended rate of application is 5.5-6.5 square meters per kg. This corresponds to that at which AT-CURE (AC) has been tested, and at which it attains the claimed degree of curing efficiency. In favorable conditions such as shaded interior surfaces, adequate curing can be achieved with extended coverage rates.
  • When using AT-CURE (AC) for floor areas where maximum chemical and wear resistance is required, it is recommended that a further coat be applied after 24 hours.
  • In place of the above recommendations, the rates of cover stipulated in a specification should at all times be observed.


COLOUR White liquid
COVERAGE 5.5 – 6.5 sq mt per kg
SPECIFIC GRAVITY (@ 25°C) 1.02 ± 0.01
DRYING TIME (AS PER ASTM C 309) 60 mins at 25°C


      Surface must be sound and properly finished. Surface is ready for application of AT-CURE (AC), when damp, but not wet, and it can no longer be marred by foot traffic.
      Level any gouges. Remove all dirt, dust, oil, grease, asphalt, and foreign matter. Clean with caustics and detergents as required. Citrus degreaser is excellent for removing oil stains and many curing compounds. Rinse thoroughly and allow drying. Apply AT-CURE (AC) to damp but not wet surfaces.
      Restore surface to soundness by patching, grouting, and filling cracks or holes. Surface must also be free of any dust, dirt, and other foreign matter. Use power tools or strippers to remove any incompatible sealers or coatings. Clean as required, following procedure under “Newly cured bared concrete”.
      Stir AT-CURE (AC) thoroughly before using. Apply a continuous, uniform film by low-pressure spray, short nap roller or brush. If the substrate temperature exceeds 40⁰C, adequate measure should be taken to bring down substrate temperature below 40⁰C; preferably by spraying water before the application of AT-CURE (AC), this will help to obtain better results.
      The resin in AT-CURE (AC) ensures that bond is maintained with adhesives used for installing tiles, and other floor coverings. AT-CURE (AC) will act as a primer for paint systems and will enable most surface treatments to progress with minimal delay.

Typical surface treatments that will bond to surfaces treated with AT-CURE (AC) are:

  • Water based emulsion paints containing PVA, PVC and acrylic co-polymers.
  • Tile adhesives based on the above polymers.
  • Bituminous emulsions and solutions.
  • Thin section polymer modified cementitious systems.
  • Polyurethane resin systems.
  • Polysulphide systems.
  • Epoxy resin compositions which do not rely on penetration for substrate bond.


  • Use fresh water to clean rollers and spray equipment before AT-CURE (AC) become dry.
  • Any excess cured material will have to be mechanically removed.


  • AT-CURE (AC) has flash point at 30°C. Safety goggles should be worn during application. Spillages should be washed out immediately with cold water. For further information refer to the material safety data sheet.
