LOW VISCOSITY INJECTION EPOXY
Provides a low-viscosity, easy-flowing
injection epoxy in a unique, unitized package.
SEALTIGHT REZI-WELD LV Low Viscosity Injection Epoxy is a two-component,
easy-flowing, low-viscosity structural epoxy adhesive suitable for pressure
injection of cracks, and as a binder for a wide variety of maintenance, repair
and concrete rehabilitation patching and grouting applications.
SEALTIGHT REZI-WELD LV Low Viscosity Injection Epoxy is 100%
solids, moisture insensitive, very low viscosity, high modulus, and high
strength structural injection resin. REZI-WELD LV is V.O.C. compliant and
resists most chemicals.
REZI-WELD LV features a unique and innovative unitized
packaging concept. It combines two color-coded, pre-measured, components into an
easy-to-handle, single unit along with a handy, wood mixing paddle. The unitized
packaging eliminates mishandling and mismatching of the components on the
REZI-WELD LV is designed for gravity feeding or pressure injecting
using two-component metering systems, hand-held bulk guns or pressure pots. It
is suiable for injecting fine, non-moving structural cracks for permanent
When mixed with sand or aggregates REZI-WELD LV makee an economical, easy-to-use
epoxy mortar for patching or repairing defects in concrete substrates, securing
machinery base plates to concrete floors, interior non-skid pathways and
structural bonding applications.

SURFACE PREPARATION: All surfaces to be
bonded must be free of standing water and completely clean of dirt, rust, curing
compounds, grease, oil, paint, waxes and other materials which would prevent a
Concrete should be cleaned by mechanical abrading or
sandblasting to a sound surface. Vacuum or blow dust away with compressed air.
Mechanically abrade metal base plates to a bright metal finish.
Exposed steel surfaces should be sandblasted and vacuumed clean; if not
possible, degrease the surface and use sandpaper or a wire brush to reveal
continuous, bright metal.
MIXING NOTE: Condition all components to 60-85ºF for 24 hours prior to use.
Pre-mix each component. Mechanically mix at slow speed (600-900 rpm) using a
drill and Jiffy Blade or drum mixer to 3 minutes or until completely mixed while
scraping the sides to ensure complete blending of components. Avoid air
entrapment. Mix only very small quantities by hand for a minimum of 3 minutes or
until sufficiently blended together using the supplied stirring stick. Scrape
the sides of the container to ensure complete blending of components. Mix only
the amount of epoxy that can be applied within the product's potlife. Potlife
will decrease as the ambient temperature and/or mass size increases.
INJECTION: Epoxy can be gravity fed into horizontal cracks that are small,
(1/4" [6.35mm] maximum width) and have a limited depth. For large injection
projects, a self-proportioning, mixing and pressure injection equipment is
recommended. For small injection projects, SEALTIGHT REZI-WELD RAPID SET PRE-PAK
self-contained, barrier-type cartridge may be suitable.
INTERIOR, NON-SKID PATHWAYS: For thin applications, apply at a rate not to
exceed 110 ft.² per gallon (2.70m²/liter). For heavy coverage, apply layer of
sand or grit over epoxy and allow to set. Blow excess sand away. NOTE: REZI-WELD
LV IS NOT TO BE USED AS A FINISHED FLOOR COVERING OR PROTECTIVE TREATMENT.
AGGREGATES FOR EPOXY-RESIN MORTARS: Combine clean, dry aggregates with freshly
mixed epoxy in a ratio of 1 part epoxy to 1 to 4 parts, by volume, of graded
aggregates. Patch thickness should not exceed 1-1/2" (38.1mm) per lift.
CLEANUP: Clean tools and equipment immediately with Toluene avoiding heat,
sparks, open flame, breathing vapors or allowing epoxy-containing solvent to
contact skin. Never wash hands with solvent.

Two years in unopened, damage-free
containers stored in a dry environment between 40º and 95ºF (4º and 35ºC).
One gallon (3.8 liter) neat covers approximately 85-110 ft.²
(2.09-2.70 m²/liter) depending on the surface porosity and end use application.
One gallon (3.8 liters) mixed 1:1 with dry aggregate yields approximately 350
in.³ (5.135.45cm³) of grout.
DO NOT DILUTE. Mix complete units only. The epoxy must be between
60º and 85ºF (16 and 29ºC) at time of mixing. Warm by placing containers into
hot water. The preferred method is to store the epoxy in a warm room prior to
use. Surface substrate temperature must be between 40º and 90ºF (4 and 32ºC).
Do not seal cracks while under hydrostatic pressure.
REZI-WELD LV is not to be used as an exterior coating as it is not resistant to
ultraviolet rays. This epoxy is corrosive. Personal protective equipment is
necessary. Unused epoxy will generate excessive heat, especially in large
quantities. Unused epoxy should be mixed with dry sand in the container to help
lower the heat. Read and follow application information, precautions and
Material Safety Data information.
