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.
- 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).
- 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)
- 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.
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).
- 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.
- 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.
