EXPOSED STEEL PRIMER
SEALTIGHT PATCH-PRIME is a polymer modified,
cementitious-based, two-component material consisting of a dry powder and a
liquid component, packaged as a unit in a mixing container.
PATCH-PRIME provides rust-proofing protection for steel reinforcement
(i.e. rebar, anchor bolts, bearing plates, etc.) and other steel building
components exposed during preparation for concrete repairs, where a cementitious
repair material will be applied - horizontal, vertical, or overhead.
PATCH-PRIME replaces smooth, non-absorbent, epoxy rustproofing coatings. It is
suggested for use with all SEALTIGHT cementitious patching compounds.
Advantages and Benefits
|Non-toxic water-borne mixture
|Excellent adhesion to steel, concrete and repair
|Easy to apply by brush
|Easy water cleanup after use
|Alkalinity similar to concrete
|If applied to concrete surfaces adjacent to rebar, it
will not act as a bond-breaker
|Coating is vapor permeable
|Contains migrating corrosion inhibitor|
Do not apply to unclean, rusty steel. Do not
apply when rain is imminent or when the temperature is expected to be below
40ºF (4ºC) within 24 hours. At temperatures above 90ºF (32ºC), the pot life
and work life is severely limited.

13 lb. (5.9 kg) multi-part kit
Single coat: 24 ft.² (2.23m²) of surface area per unit. Recommended 2
coat application, 12 ft.² (1.11m²) per unit. One unit is sufficient for 100
ft. (30.5m) of #4 1/2" (12.7mm) rebar, 2 coats.
Keep from freezing. Should liquid component freeze, it becomes unusable
and must be discarded. Keep lid on the liquid and on the mixing pail itself in
storage, to keep powders dry.
SURFACE PREPARATION: All steel surfaces to be primed should be
sandblasted and or water blasted, to remove all rust, grease, etc.
MIXING: (Step 1) Remove the 2 bags of powders and the container of liquid from
the mixing pail container. (Step 2) Pour the liquid component into the mixing
pail and then add the bags of premixed dry component into the pail. Mix both
parts together using a drill with a mixing paddle. Mix to a smooth, lump-free,
brushable consistency. Allow the mixed material to sit for 3 to 5 minutes and
the re-mix. Mix only the amount of material which can be applied within 45
minutes after mixing. Discard any mixed material not used within this time.
PRIMER APPLICATION: Apply the first coat to the cleaned steel, using a stiff
brush, as soon as possible after the steel is cleaned. Let the first coat dry
for approximately 10 to 15 minutes and then apply the second coat.
CURING: Allow the primer to stiffen for 1 to 2 hours before placing the repair
material. The placement of the repair compound may follow the initial curing, or
be delayed as necessary. It is important that the primer be kept clean during
CLEANUP: Clean all tools and equipment after use with soap and water. Cured
material would need to be removed mechanically.
Avoid direct contact with this product. Chemical resistant gloves and
goggles are recommended. If contact occurs, wash affected areas with mild soap
