Description
:
Roadware 10 Minute Concrete Mender is a high-penetration two-part
hybrid urethane that combines with sand to form a tough instant
polymer concrete. This nearly water thin formula is designed to
break the surface tension of concrete thus creating extremely
high bond strengths and permanent repairs.
Roadware 10 Minute Concrete Mender produces polymer concrete repairs
that absorb the shock of heavy traffic without cracking or disbonding.
It is highly chemically resistant and can be applied in a wide
range of temperatures. It is excellent for industrial floor repairs
subject to forklift traffic and harsh conditions.
Uses:
Limitations:
10 Minute Concrete Mender is designed for
use on interior or exterior concrete surfaces. It is not intended
for repairing areas of movement such as exterior cracks and joints
subject to regular freeze /thaw cycling. It must be applied to
concrete free of surface moisture.

Preparation:
Surface Cracks (all depths and widths): Cracks should be free
of dirt, oils, dust, latents and old crack repair materials. ALL
SURFACES MUST BE CLEAN AND DRY. New concrete must be fully cured.
A wire brush, twisted wire wheel, or diamond blade attached to
an electric hand grinder is recommended for preparing cracks and
creating a clean surface for bonding.
Surface Spalls and Deflections: Remove all loose materials back to sound concrete with a chisel or light chipper. DO NOT SQUARE CUT THE REPAIR AREA. If a square appearance is necessary, lightly score surface and remove material. Use a wire brush or twisted wire wheel to clean the repair area. All surfaces must be free of dirt, oils, dust, latents and old repair materials. New concrete must be fully cured.
Mixing:
Cartridges: 10 Minute Concrete Mender is a two component material
and must be thoroughly mixed at a ratio of 1 part "A"
to 1 part "B" by volume. Mixing and metering of 10 Minute
Concrete Mender is achieved with self-mixing cartridges provided
by Roadware, Inc. Material is ejected from prepackaged cartridges
through a supplied static mixing nozzle with a dual component
caulking gun such as the Roadware 5300 Application Tool, Mixed
material is applied directly into the repair area immediately
after mixing.
Bulk: Due to the rapid setting nature of the product, pot-mixing of the components is not recommended for crack and joint repairs less than 3/4" in width. 10 Minute Concrete Mender supplied in 10 gallon kits may be bucket mixed in quart batches and applied immediately to the repair area. Combined one pint of Part A with one pint of Part B. Mix with a drill mixer or hand mixing stick for 30 seconds or until well blended. Add 2 quarts of manufactured sand and mix for an additional 10 seconds. Pour the entire batch into the repair area immediately. SEE BULK MIXING INSTRUCTIONS INCLUDED WITH MATERIAL. 10 Minute Concrete Mender may be dispensed through a one-to-one ratio pump specifically designed to handle extremely low viscosity materials while maintaining exact ratios. The system must not allow the two components to combine until they reach the point of delivery. Contact Roadware for information on acceptable pumping equipment. All pumping equipment must be approved by Roadware, Inc. prior to application.
Application
Methods:
Surface Cracks (all depths and widths): Assemble cartridge according
to directions. Holding the SYLCAT application gun upward, place
cartridge set into gun. Gently squeeze trigger to bleed-off air
and start material flowing into mixers. Point mixer into waste
container and squeeze trigger to start mixing process. DO NOT
POINT MIXER UPWARD AFTER MATERIAL IS FLOWING. This may cause material
to flow back into the tubes and cause clogging.
Pre-wet repair area with material. Fill with 30-40 grit manufactured
silica sand and additional material to grade. Be sure to saturate
all of the sand completely. Additional sand may be added to the
repair as necessary. Saturated sand may be moved into place with
a small squeegee or scraper. Work with one small section at a
time. Do not stop flowing material for a period of more than 2
minutes. If material sets inside mixer, remove cartridge from
gun and replace mixer.
Fill all repair areas to grade. When material cures (turns gray)
in about 10 minutes, remove excess material with a sharp scraper
for a smooth and flat finish.
Spalls: Pre-wet repair area with mixed Concrete Mender without sand. Fill with 30-40 grit manufactured silica sand and additional material to grade. Be sure to saturate all of the sand completely. Additional sand may be added to the repair as necessary. Saturated sand may be moved into place with a small squeegee or scraper. Work with one small section at a time. Do not stop flowing material for a period of more than 2 minutes. If material sets inside mixer, remove cartridge from gun and replace mixer. A trowel or scraper may be used to move saturated sand into place and to create a level surface. If required, surface friction may be maintained by adding additional manufactured to the surface as the material cures. Allow to cure (approximately 10 minutes). Finished repairs may be "cleaned up" by sanding or buffing within a few hours of application.
Color:
10 Minute Concrete Mender is composed of an amber colored liquid
and a violet colored liquid. The material is black when dispensed
and cures to a gray finish. Alternate colors can be achieved by
selecting different colors of manufactured sand. 10 Minute Concrete
Mender will lighten in color when exposed to ultraviolet rays.
This natural occurrence within urethanes will NOT effect the physical
properties of the material or the repair.
Clean
Up:
Clean all tools and equipment immediately after use with acetone,
xylene, MEK, or toluene. Cured material may be removed by soaking
or abrading. 10 Minute Concrete Mender is very aggressive, gloves
should be worn to keep material from contacting skin. Use an industrial
paint and stain hand cleaner to remove from skin.
Curing:
10 Minute Concrete Mender will cure in approximately 10 minutes
from application at 72° F for most traffic situations. The
material will reach it's full strength in 24 hours. Cure rates
in extremely cold environments should be tested beforehand.
CAUTION:
Roadware 10 Minute Concrete Mender Part A contains diphenylmethane-diisocyanate
(MDI) CASS# 101-68-8, napthelene CASS# 91-20-3, and petroleum
hydrocarbon CASS# 64742-94-5.
Risks:
Inhalation of mists and vapors may cause dry throat, cough, dizziness,
headache, nausea, unconsciousness and other central nervous systems
effects. MDI can induce respiratory sensation with asthma-like
symptoms. Repeated and prolonged contact with skin can cause irritation.
Emergency And First Aid Procedures:
Eye contact - flush eye with water for at least 15 minutes. Get
medical attention promptly. Inhalation - remove person to fresh
air, if breathing is difficult administer oxygen. Get medical
attention immediately. Skin contact - wipe off and wash thoroughly
contacted area with soap and water. Ingestion - do not induce
vomiting. Consult physician immediately.
Precautions:
Provide adequate ventilation to keep the airborne concentration
of diisocyanate below TLV limit. For concentration above TLV limit,
use of a positive pressure self- contained breathing apparatus
(SCBA) or NIOSH/MSHA approved positive pressure supplied air respirator
with a full face piece and escape (SCBA) required. Use protective
equipment to minimize skin contact. Wear chemical safety goggles,
and laboratory coats or aprons to avoid skin contact. Provide
access to safety shower and eye wash stations.
