TAMMS FORM AND POUR

TECHNICAL DATA SHEET
TAMMS FORM AND POUR
CONCRETE REHABILITATION
CONCRETE
FEATURES AND BENEFITS
• 3/4 - 3" depth repairs
• Can be extended with pea gravel for deeper
repairs
• Contains a migratory corrosion inhibitor
• High bond strength
• Pumpable
• Compatible with coefficient of thermal
expansion of concrete
• Easily mixed
APPLICATIONS
• On grade, above and below grade on
concrete
• Horizontal surfaces and formed vertical
and overhead surfaces
• Repair material for parking facilities,
industrial plants, walkways, bridges,
tunnels, dams and balconies
• Filler for voids and cavities
SURFACE PREPARATION: Surface must be
structurally sound, clean and free of loose or
deteriorated concrete, dust, dirt, and all
contaminants. Edges of area to be patched must
be vertical, chipped or steep angle cut, to a
minimum depth of ¾”. Clean and prime exposed
steel and reinforcing with DURALPREP AC. If
substrate is not absorptive, abrade as necessary
to obtain proper profile for good adhesion. Flush
area with clean water to remove all dust and
dampen the concrete. Wipe off any excess water
or puddles prior to placement of TAMMS FORM
AND POUR. The surface should remain damp
during placement of TAMMS FORM AND POUR.

Typical results obtained under laboratory conditions
small quantities. For larger applications use a paddle
type mortar mixer or a standard concrete mixer. Do
not add additional water. Mix for 2-3 minutes until a
smooth flowable consistency is achieved.

One Component, Flowable, Shrinkage Compensated Concrete
application depths in excess of 3 inches add 30
pounds of 3/8” to 1/2” clean, saturated surface dry
pea gravel per 50 pound bag of TAMMS FORM
AND POUR.
PACKAGING: 50 lb poly-lined bags.
Storage: Covered storage away from all moisture.
Shelf Life: One year in protected storage.
Freight Class: Class 55
APPLICATION TECHNIQUES: The unrestrained
surface area of the repair should be kept to a
minimum. TAMMS FORM AND POUR should be
mixed, placed and finished within 30 minutes. Pour
the mixed material into the prepared area to be
patched. Screed and trowel the material so as to
level with the existing concrete. If required, lightly
trowel to seal the edges, and finish the surface as
desired. Do not overtrowel or featheredge. Follow
ACI guidelines for proper curing. On windy or hot
days or when under direct sunlight, wet curing is
recommended.
TECHNICAL SERVICE: For application procedures
or surface conditions not specified above, please
contact:
COVERAGE: One 50 lb. bag yields approximately
0.42 cubic feet.
CLEAN-UP INSTRUCTIONS: Clean application
tools and mixer with water immediately after use.
Hardened TAMMS FORM AND POUR will be
difficult to remove.
CAUTIONS: Minimum depth of patching is ¾”. Do
not add any additives to TAMMS FORM AND
POUR. The patch area should be frost free prior to
application. Do not apply at temperatures below
40°F.
ENVIRONMENTAL
AND
SAFETY
PRECAUTIONS: Industrial Use Only. Product
contains Portland cement which is alkaline on
contact with water. Do not breathe dust. May
cause delayed lung injury (Silicosis). IARC reports
