Pourable construction grout makes it easy to fill the tough spots

 

Sakrete Precision Non-Shrink Construction Grout is a non-shrink and non-metallic. When properly mixed to a fluid consistency allows for pumping grout to areas where it is difficult to access using conventional grouting methods.

Preparation/Application:

  • Use only when the product, air, and surface temperature are above 400F (40C) for a minimum of 24 hours.
  • Clean area and remove all unsound concrete, grease, oil, paint, and any other foreign material that will inhibit performance.
  • Prior to grout placement, all surfaces must be clean and saturated with water for 24 hours. Remove excess water bringing it to a surface saturated dry condition (SSD).
  • Provide air relief holes where necessary if grouting is beneath large plates.
  • Wood form work or other absorbent forms should be coated with a form release oil to prevent grout adherence and water absorption.
  • Design form work to facilitate rapid, continuous and complete filling of the space to be grouted. Rodding the grout lightly will help move material.
  • Use methods that will enable the grout to flow by gravity between the surfaces and keep the grout in full contact with these surfaces until it has hardened.
  • Avoid vibration which can cause bleeding and segregation. Shut down nearby machines for a minimum of 24 hours. 
  • Minimum application thickness is 1” (25 mm) and a maximum thickness of 4” (100 mm).

Mixing:

  • Only mix with clean potable water. The water quantities shown are approximate and may vary slightly with the type of equipment and application conditions.
  • Water demand and mix temperature must be determined using standard test methods for consistency and temperature measurement at the time of application.
  • Place 3/4 of desired mixing water, start mixer then slowly add the dry material. After all of the powder has been added, slowly add the remaining 1/4 water until the desired consistency is achieved.
  • Avoid adding excessive amounts of water that promotes segregation or bleeding of the grout.
  • Mix for 3 - 5 minutes to ensure a uniform lump free consistency and place immediately.

 

Desired grout consistency:

  • Fluid: 1 gal + 1 pt (4.3 L) per 50 lb (22.7 kg)
  • Flowable: 1 gal (3.8 L) per 50 lb (22.7 kg)
  • Plastic: 3 qts + 1 pt (3.3 L) per 50 lb (22.7 kg)

Curing:

  • Sakrete Construction Grout can be exposed under normal weathering conditions. 
  • Forms may be removed as soon as the grout reaches its final set. 
  • Prevent rapid water loss by covering the exposed grout surfaces with wet burlap during the first 48 hours or apply an acceptable water based cure and seal agent.
  • Protect from freezing for a minimum of 48 hours after placement. ACI 308 Standard Practice for Curing Concrete.

Precautions:
Air, mix and substrate temperatures should be between 40°F and 100°F (4°C and 38°C).

  • Colder temperatures or higher humidity conditions will retard set times.
  • Do not use in applications of high dynamic loading.
  • Do not retemper grout by adding water.
  • Do not use as a floor topping or in large areas with an exposed shoulder around base plates.
  • Do not add accelerators, retarders, plasticizer or other additives.
  • Do not apply in application thicknesses <1” (25 mm) or > than 4” (100 mm).

 

Safety:

  • READ and UNDERSTAND the Safety Data Sheet (SDS) before using this product.
  • WARNING: Wear protective clothing and equipment.
  • For emergency information, call CHEMTREC at 800-424-9300 or 703-527-3887 (outside USA).
  • KEEP OUT OF REACH OF CHILDREN.

 

NOTES:

  • It is the responsibility of the installer/applicator to ensure the suitability of the product for its intended use.
  • For installation where acids and sulfates are present, a protective coating is required. Protect uncoated aluminum from direct contact with Portland cement-based materials.
