SikaGrout®-885 MF vs Control

1. The ambient and initial temperature of the grout should be in the range of 45 to 90° F (7 to 32° C) for both mixing and placing. For precision grouting, store and mix grout to produce the desired mixed grout temperature. If bagged material is hot, use cold water, and if bagged material is cold, use warm water to achieve a mixed-product temperature as close to 70° F (21° C) as possible.
2. If temperature extremes are anticipated or special placement procedures are planned, contact your local Sika representative for assistance.
3. When grouting at minimum temperatures, see that the foundation, plate, and grout temperatures do not fall below 40° F (7° C) until after the final set. Protect the grout from freezing (32° F or 0° C) until it has attained a compressive strength of 3,000 psi (21 MPa) in accordance with ASTM C 109.

Recommended Temperature Guidelines for Precision Grouting

This product when discarded or disposed of, is not listed as a hazardous waste in federal regulations. Dispose of in a landfill in accordance with local regulations. For additional information on personal protective equipment, first aid, and emergency procedures, refer to the product Safety Data Sheet (SDS) on the job site or contact the company at the address or phone numbers given below.

One 55 lb (25 kg) bag of SikaGrout®-885 MF grout mixed with approximately 10 lbs (4.5 kg) or 1.2 gallons (4.5 L) of water yields approximately 0.43 ft³ (0.012 m³) of grout.
Note: The water requirement may vary due to mixing efficiency, temperature, and other variables.

1. Steel surfaces must be free of dirt, oil, grease, or other contaminants.
2. The surface to be grouted must be clean, SSD, strong, and roughened to a CSP of 5–10 following ICRI Guideline 310.2 to permit proper bond.
3. When dynamic, shear, or tensile forces are anticipated, concrete surfaces should be chipped with a “chisel-point” hammer, to a roughness of (plus or minus) 3⁄8" (10 mm). Verify the absence of bruising following ICRI Guideline 210.3.
4. Concrete surfaces should be saturated(ponded) with clean water for 24 hours just before grouting.
5. All freestanding water must be removed from the foundation and bolt holes immediately before grouting.
6. Anchor bolt holes must be grouted and sufficiently set before the major portion of the grout is placed.
7. Shade the foundation from sunlight 24 hours before and 24 hours after grouting.

By using the minimum amount of water to provide the desired workability, maximum strength will be achieved. Whenever possible, mix the grout with a mortar mixer or an electric drill with a paddle such as ICRI 320.5 type A, D, E, F, G, or H. Put the measured amount of potable water into the mixer, add grout, and then mix till a uniform consistency is attained. Do not use water in an amount or a temperature that will cause bleeding or segregation.

Note: The water requirement may vary due to mixing efficiency, temperature, and other variables.

1. Place estimated water (use potable water only) into the mixer, then slowly add the grout. For a fluid consistency, start with 9 lbs (4 kg) (1.1 gal [4.2 L]) per 55 lb bag.
2. The water demand will depend on mixing efficiency, material, and ambient temperature conditions. Adjust the water to achieve the desired flow. Recommended flow is 25–30 seconds using the ASTM C 939 Flow-Cone Method. Use the minimum amount of water required to achieve the necessary placement consistency.
3. Moderately sized batches of grout are best mixed in one or more clean mortar mixers. For large batches, use ready-mix trucks and 3,300 lb (1,500 kg) bags for maximum efficiency and economy.
4. Mix grout for a minimum of 5 minutes after all material and water is in the mixer. Use a mechanical mixer only.
5. Do not mix more grout than can be placed in approximately 30 minutes.
6. Transport by wheelbarrow or buckets or pump to the equipment being grouted. Minimize the transporting distance.
7. Do not retemper grout by adding water and remixing after it stiffens.
8. Do not add plasticizers, accelerators, retarders, or other additives.

Placement

1. Always place grout from only one side of the equipment to prevent air or water entrapment beneath the equipment. Place SikaGrout®-885 MF in a continuous pour. Discard grout that becomes unworkable. Make sure that the material fills the entire space being grouted and that it remains in contact with the plate throughout the grouting process.
2. Immediately after placement, trim the surfaces with a trowel and cover the exposed grout with clean wet rags (not burlap). Keep rags moist until the grout surface is ready for finishing or until the final set.
3. The grout should offer stiff resistance to penetration with a pointed mason’s trowel before the grout forms are removed or excessive grout is cut back. After removing the damp rags, immediately coat them with a recommended curing compound compliant with ASTM C 309 or preferably ASTM C 1315.
4. Do not vibrate grout. Use steel straps inserted under the plate to help move the grout.
5. The minimum placement thickness is 1" (25 mm). Consult your Sika representative before placing lifts more than 6" (152 mm) in depth.

Application

• Contact your local representative for a pre-job conference to plan the installation.
• Always place grout from only one side of the equipment to prevent air or water entrapment beneath the equipment. Place SikaGrout®-885 MF in a continuous pour.
• The minimum placement thickness is 1" (25 mm). Consult your Sika representative before placing lifts more than 6” (152 mm) in depth.
• The water requirement may vary with mixing efficiency, temperature, and other variables
• Should not be used as a floor topping.
• Large, exposed areas of grout should be avoided.
• The structural integrity of the grout is not affected by superficial, hairline cracks occasionally observed in shoulders, near base plate edges, and around anchor bolts.
• The ambient and initial material temperature of the grout should be in the range of 45 to 90° F (7 to 32° C) for both mixing and placing. ideally, use the amount of mixing water that is necessary to achieve a 25–30 second flow specified by ASTM C 939 (CRD C 611). For placement outside of 45 to 90° F (7 to 32° C), contact your local Sika representative.
• Surfaces may discolor in certain environments; it is not an indication of product performance.

Cure all exposed grout with an approved membrane curing compound compliant with ASTM C 309 or preferably ASTM C 1315. Apply the curing compound immediately after the wet rags are removed to minimize potential moisture loss.
