Application
All grouting should be done using established procedures according to American Concrete Institute recommendations: ACI 351.1R-93 "Grouting for Support of Equipment and Machinery"

SURFACE PREPARATION: All grout surfaces must be clean, dry and completely free of laitance, oil, grease, other coatings and any other contamination. Unsound concrete must be chipped out, leaving surface level, but rough. Grout area should be saturated with water 12-24 hours prior to grouting. Remove all excess water before placing grout. Surface should be saturated, surface dry (SSD).

FORMING: Method of forming must provide for rapid, continuous grout replacement. For pouring, allow a minimum clearance of 3" for entry and 6" minimum grout "head". Forming must also provide for venting to avoid entrapment of air. Provide 1/2" minimum form clearance on all sides and 1" clearance for "head".

MIXING: Small quantities of 588 GROUT may be hand mixed in a concrete mixing pan until lump-free.. For large quantities and continuous pours, mix using a mortar mixer with rubber-tipped blades or appropriate grout pump for a minimum of 5 minutes. Use minimum water required to produce desired placement consistency. Use 6.5 pts. (3.1 liters) of water per bag of grout for plastic consistency; 7.25 pts. (3.4 liters) for medium flow (pourable) and 8.25 pts. (3.9 liters) for high flow.

Mix in 2 steps: Add 2/3 of water requirement...add grout...after partial mixing, add remainder of water for desired consistency. Thoroughly mix total quantity for 2 to 3 minutes. Do not mix more than can be placed in 30 minutes.

PLACEMENT: 588 Precision Grout is easily placed by pouring or pumping; compaction can be accomplished by rodding or light vibrating. Place grout on one side, flowing to opposite and adjacent sides to avoid entrapment of air. When necessary, provide vent holes. Grout "head" and excess grout may be removed after initial set.

CURING: Forms may be removed after grout has hardened to an initial set, usually within 4 to 6 hours. At this point, make final finish. Prevent rapid loss of water by covering with wet burlap during first 48 hours or apply appropriate SEALTIGHT Curing or Curing and Sealing Compound. (We suggest SEALTIGHT 1640-White or CS-309-1315).

Cost reductions are realized by extending with clean, 3/8" (9.5mm) pea gravel. In applications where grout thickness is to be 2" to 5" (50 to 130mm), up to 25% of aggregate, based on weight of grout, may be added. For thicknesses over 5" (130mm) up to 50% of aggregate may be added. Such additions may be made to the flowable mix.
