SEMI-RIGID EPOXY JOINT/SEALANT
SEALTIGHT REZI-WELD FLEX is a gray, two-part, 100% solids, pourable consistency,
premium-grade, moisture insensitive, epoxy joint filler/sealant formulation.
When cured, it is semi-rigid, with a Shore D Hardness of 53.
SEALTIGHT REZI-WELD FLEX was developed for use as a joint
filler/sealant for narrow saw cut, preformed and construction joints in interior
concrete floors subjected to load bearing, wear or impact conditions, such as
warehouse and industrial plants. These are floors which are typically subjected
to hard-wheeled vehicles (such as forklifts).
REZI-WELD FLEX is also suitable for filling or repairing random cracks caused by
spalling or shrinkage, as a flexible adhesive for non-structural applications,
or as a traffic-loop and control wire joint filler.
Advantages and Benefits
|Fast setting, pourable and self-leveling makes it ideal
for saw cut joints
|As a semi-rigid filler, it protects slab edges from
spalling, yet allows sufficient flexibility for interior slabs|
Do not use in vertical or sloping joints, or
in areas subject to continuous water immersion. Do not use in joints designed
for any significant movement (i.e. expansion or contraction joints). Do not
apply when concrete temperature is below 40ºF (4ºC). This product is
recommended for interior use only. It is not suitable for areas subject to
sudden extreme temperature changes. Concrete must be a minimum of 28 days old
prior to installation.

Joint frequency, width and depth shall be as
specified by the design engineer. It is suggested that the width of a typical
saw cut shall be 1/4" (6.4mm) maximum and the depth 25% of the slab
thickness, but no less than 1" (25.4mm).
JOINT PREPARATION: Joints must be level, clean and free of frost and
standing water. Remove curing compounds, form release agents, old sealant and/or
contaminants from joint surfaces by sandblasting or mechanical abrading. Blow
any dust, dirt and laitance out of the joint with oil-free compressed air prior
to application. To prevent run out from cracks in the bottom of joints, apply a
small amount of fine dry sand. Install full depth. Do not use with soft backer
MIXING: Mixing ratio is 1:1 by volume. DO NOT DILUTE. Prior to mixing, condition
both components to 60º to 85ºF (15.5º to 29.5ºC). After conditioning, de-rim
both cans and mix all of component “B” with component “A” (being careful
to scrape the sides and bottom of both containers to ensure removal of all
material). Mix for 2 to 3 minutes to an even color. Use as soon as possible.
Pot Life varies with temperature. At higher temperatures, pot life is shorter,
while at lower temperatures, it is longer. Mix by hand or variable low-speed
drill (400-600 rpm) using a paint mixing paddle. Mixed material must not contain
streaks or lumps. Product container provides complete information. Read and
follow all instructions and precautions.
DISPENSING: Pour mixed material directly from the can. Best results are obtained
using a closed barrel caulking gun. Fill joint to within 1/2" of the top
and allow to settle. Within 15 to 30 minutes, apply a second layer flush with
the floor, checking occasionally for low spots (due to seepage) or overfill the
joint. Allow the material to cure until it is almost solid, then shave, grind or
sand off the excess to the desired floor level.
CLEANUP: Prior to solidification, clean all tools and equipment with Toluene or
Xylene. Spilled material must be collected with absorbent material and disposed
of in accordance with local, state and Federal regulations. Remove solid
All skin areas should be protected by clothing and gloves, as some
persons may develop a skin rash from contact. Base components or mixed, uncured
material, can produce irritation of the eyes. In case of eye contact,
immediately flush thoroughly with water for at least 15 minutes. Seek immediate
medical attention. Wash skin with soap and water if contact with skin is made.
Do not use solvents.
