LOW-VISCOSITY (LV) EPOXY INJECTION PRE-PAK
Provides a high-modulus, high-strength,
self-leveling material for a variety of concrete restoration projects.
SEALTIGHT REZI-WELD RAPID SET Injection Epoxy is a clear,
two-component, low-viscosity, rapid-setting, penetrating epoxy compound. RAPID
SET offers high-modulus and high-strength characteristics. It is chemical
resistant and moisture insensitive. The product bonds cured concrete or metal to
concrete. RAPID SET is fast, easy-to-use and provides a VOC compliant
SEALTIGHT REZI-WELD RAPID SET Injection Epoxy is designed to be
either gravity fed or pressure injected into concrete cracks for restoration of
bridges, buildings, highways or any concrete construction requiring repair.
Advantages and Benefits
|Seals small cracks in concrete surfaces inside or
|Bonds cured concrete or metal to concrete
|Sets anchor bolts in concrete
|Fast, easy-to-mix and apply, pre-packed, two-component,
user-friendly packaging with barrier-type cartridge
|Complies with VOC regulations
|Improves resistance to industrial chemicals and is
Convenient, easy-to-use SEALTIGHT REZI-WELD RAPID SET
Injection Epoxy is pre-packed in two-component, barrier type cartridges. Each
cartridge contains 10 ounces (295.74 ml) of low-viscosity epoxy when properly
mixed. Once mixed, cartridge may be inserted into a standard caulking gun for
SURFACE PREPARATION: Mechanically abrade
all surfaces to be bonded. Substrates must be dust free, clean and void of all
contaminants, and should be dry for optimal adhesion. All steel surfaces must be
abraded to a white metal finish.
Prior to injecting, all cracks must be cleaned either by
blowing out with oil free compressed air or vacuumed to remove all contaminants
and loose particles.
MIXING NOTE: Cartridge must be between 60º - 85ºF (16º
- 29ºC) at time of mixing. (See PRECAUTIONS).
CAUTION: WEAR GLOVES AND SAFETY GOGGLES OR OTHER EYE PROTECTION DURING ALL
OPERATIONS. Consult and follow all mixing and application directions included
INJECTION: Epoxy can be gravity fed into horizontal cracks that are small,
1/4" (6.35mm) maximum width, and have a limited depth. Inject epoxy from
caulking gun into the crack and fill to the top. Allow gravity to pull epoxy
into the void. Top off with more epoxy and finish. Repeat as necessary.
RAPID SET PRE-PAK is not to be used for sealing cracks while under hydrostatic
pressure. NOTE: For larger injection projects, a self-proportioning, mixing and
pressure injection piece of equipment is mandatory, and a low-viscosity epoxy
adhesive with an extended pot life, such as SEALTIGHT REZI-WELD LV LOW VISCOSITY
EPOXY (Catalog Number 392) may be preferred.
OTHER BONDING: To bond cured concrete or metal to concrete, apply sufficient
amount to the properly prepared surface and join together immediately. No firm
clamping pressure is necessary beyond what will hold the parts in place. NOTE:
All concrete surfaces to be bonded to should be at least 28 days old.
CLEANUP: Tools and equipment should be cleaned immediately with Xylene or
Toluene. Clean equipment away from heat, sparks and open flame and avoid
breathing vapors or allowing epoxy-containing solvent to contact skin. Should
this material come in contact with the skin, wash thoroughly with soap and

One (1) year in unopened, damage-free
cartridges stored in a dry environment between 40º - 95ºF (4º - 35ºC).
DO NOT DILUTE. Never warm epoxy over direct heat. Warm cold epoxy
by placing the containers into hot water. The preferred method is to store the
epoxy in a warm room prior to use. The cartridge must be between 60º - 85ºF
(16º - 29ºC) at the time of mixing and is not recommended for use when the
pavement temperature for the past 24 hours has been below 40ºF (4ºC).
SEALTIGHT REZI-WELD RAPID SET PRE-PAK is not to be used on exterior surfaces as
a coating as it is not resistant to ultraviolet rays. Read and follow
application data and precautions. Refer to Material Safety Data Sheet for
complete health and safety information.
