One unit of SikaFlow®-690 is comprised of:

• One (1) pail of Part 'A' Component
• One (1) jug of Part 'B' Component
• Five (5) bags of Part 'C' Component

For application thickness > 9" (229 mm), consult Technical Services.

Condition components to approximately 65 - 75 °F (18 - 24 °C) before mixing.

Minimum: 40 °F (4 °C)

Maximum: 95 °F (35 °C)

Minimum: 40 °F (4 °C)

Maximum: 95 °F (35 °C)

Concrete, Steel

Place SikaFlow®-690 into forms within 15 minutes after mixing procedure is complete.

4 - 7 hours

One mixed unit of SikaFlow®-690 (i.e. one pail Part 'A', one jug Part 'B' and five bags of Part 'C') yields approximately 2.0 cubic feet (0.057 cubic meters)

• Protect the foundation and equipment from rain, frost and moisture.
• Seal off and protect areas that will not be grouted.
• Place forms no greater than 6" (152 mm) away from the edge of the individual base rail or soleplate on the sides where the grout is not being poured. Excessive edge thickness creates thermal stress and may result in excessive cracking. Formwork edges should allow enough room to accommodate pouring of the grout and accommodate a headbox if used. Shoulders should be a maximum of 6” (152 mm) in width. Consult your local Sika Project Representative or Sika Technical Services for specific recommendations.
• Before erecting the forms, cover interior form surfaces with a bond breaking release agent. Keep bond breaker off concrete and steel surfaces that SikaFlow®-690 must adhere to. A polyethylene or other nonbondable film may be used as a release agent.
• The top of the form should extend at least 3/4" (19 mm) above the bottom of the rail or plate.
• Forms must be liquid tight. If necessary, seal forms to clean, dry concrete surfaces by applying a bead of Sikaflex sealant, then press form into place.
• Baseplate assemblies should be well vented to prevent air entrapment during installation.
• For placements requiring long travel lengths, strapping across the underside of the baseplate may be necessary. Strapping is placed under the baseplates to help move grout due to restrictions and to minimize air entrapment.
• Use of expansion joints on large placements is recommended. Please consult with the qualified engineer of record (EOR) for specific joint design parameters, or contact Sika Technical Services for further details. To minimize the potential for cracking in the epoxy grout [maximum 3 to 6 foot (1 to 1.8 meter) spacing in each direction] is typical. Expansion joint locations should not interfere with anchor bolts.
• Field visits by Sika personnel are for the purpose of making technical recommendations only, and are not for supervising or providing quality control on the jobsite.

• Cure the foundation until design strength of the concrete is achieved and foundation is dry. Use the recommended procedure according to ACI 351.1R, "Report on Grouting Between Foundations and Bases for Support of Equipment and Machinery."
• To permit proper bond, surfaces to be grouted must be clean, sound, dry, dust free, contaminant free and roughened to a CSP of 5 - 10, following ICRI Technical Guideline No. 310.2R.
• Do not use a bushing hammer. Avoid causing microcracks in the substrate
• Chamfer the edge of the concrete 45 degrees to about a 2" (51 mm) width.
• If an anchor bolt sleeve is to be filled, be sure all water is removed. Use a siphon, vacuum pump, or rubber hose and bulb. Remove the residual moisture by either forced air or evaporation.
• Seal the anchor bolt hole to prevent SikaFlow®-690 from flowing in with felt, foam rubber or other means.
• Cover all shims and leveling screws with bond breaker to keep the epoxy grout from adhering. Use PTFE tape or other suitable bond breaker. Shims or jack pockets may be formed with wood, and forms filled with damp sand.
• Remove shims or jack screws after the grout cures.
• Shade the foundation from direct sunlight for at least 24 hours before, and 48 hours after grouting.
• Steel surfaces should be mechanically prepared to a rust free, contaminant free, bright and dry finish (per typical SSPC-SP6 / NACE 2 "Commercial Blast Cleaning" industry standards).

• Do not batch down. Mix complete units.
• Precondition all components to approximately 70 °F (21 °C) for 24 hours before using.
• Part 'C' Component aggregate must be completely dry.
• Pour the hardener (Part 'B' Component) into a pail of grout resin (Part 'A' Component) and stir by hand using a spatula or paint stirring paddle, or briefly with a low speed rotary drill (400 - 600 rpm) and jiffy mixing paddle, until well mixed to a uniform amber color. Do not overmix the liquid components.
• Pour the mixed liquids into a horizontal shaft mortar mixer or a 'KOL'-type mixer without delay.
• Add the Part 'C' Component grout aggregate, one bag at a time, and mix only until aggregate is completely wetted out to avoid air entrapment. Start the mixer just prior to adding the last bag of aggregate. Caution: Always add aggregate to the mixer after the premixed liquids have already been added.
• Mix thoroughly until a homogeneous, uniform blend of epoxy grout is achieved. DO NOT OVERMIX!

• Pour the grout into wheelbarrows or buckets for transporting to the pour site and/or pump into the forms.
• Remove mixed epoxy grout from transporting vessels and deliver into forms without delay, within 15 minutes after mixing.

Immediately after mixing operations have ceased and after the grout placement is complete, remove uncured epoxy grout from the mixer, wheelbarrows, pumps, tools and surfaces with a locally approved solvent (e.g. Acetone, MEK, Xylene). Cured material can only be removed by mechanical means.
