Provides a high-strength, cost-effective,
general purpose grout for a broad range of construction projects.
SEALTIGHT CG-86 Construction-Grade Grout is a non-ferrous, non-gaseous,
non-shrink, high-strength, cost-effective, general-purpose grout for a broad
range of large or small construction project applications.
SEALTIGHT CG-86 Construction-Grade Grout is a non-ferrous,
non-gaseous, non-shrink economical grout. It was specifically developed to
provide a high-strength, cost-effective, general-purpose grout for use across a
broad range of large and small construction projects.
CG-86 is non-gaseous and will not rust. It is furnished premixed and
ready-to-use. CG-86 may be extended for deep grouting with pea gravel for
greater yield and increased economy.
SEALTIGHT CG-86 is very versatile and may be used for either
interior or exterior applications. CG-86 is designed for base plate grouting,
anchoring, precast wall panels and bridge seats.

|No site batching required for consistent results
Concrete Mixing Pan
All grouting should be done using
established procedures according to American Concrete Institute recommendations.
SURFACE PREPARATION: All grout contact surfaces must be free of oil, grease,
scale, etc. Unsound concrete must be chipped out. Leave surface rough but level.
Grouting area must be saturated with water 12-24 hours prior to grouting. Remove
all excess water before placing grout.
POURING: Method of forming must provide for rapid, continuous grout placement.
Ensure form is well sealed.
PLACEMENT: CG-86 is easily placed by pouring or pumping
and 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: CG-86 may be cured in accordance with ACI 308. If
a membrane curing compound is used, we suggest using SEALTIGHT VOCOMP 25-1315
Curing & Sealing Compounds.
VENTING: Forming also must provide for venting to avoid air entrapment. Do not
make close fitting forms, allow 1/2" (12.7mm) clearance and 1"
(25.4mm) for "head".
MIXING: Small quantities of CG-86 Grout may be hand mixed in a concrete mixing
pan until lump free. For large quantities and continuous pours, use a mortar
mixer with rubber-tipped blades. Mix for a minimum of 5 minutes. Use minimum
water required to produce desired placement consistency. Do not mix more than
can be placed in 30 minutes. Do not retemper. Use only clean, potable water. Do
not use as a repair mortar in unconfined patches.
Set time and strength development is dependent on
temperature, therefore, follow ACI Methods during hot or cold weather grouting.
ACI 305 - "Standard on hot weather concreting"
ACI 306 - "Standard on cold weather concreting"
Cost reductions are realized when grouting large areas by adding washed, dried
and graded pea gravel. For thicknesses 2" to 5", add up to 25%
3/8" pea gravel. For medium-flow mixes, 5" and over, add up to 50%
3/8" pea gravel, plastic mix. Addition of pea gravel is based on percentage
of the weight of the dry grout.
