1. How big a crack can I fix?
Roadware 10 Minute Concrete Mender can repair cracks and spalls
of all depths and sizes. In 6 years we have not encountered a
job too big, too deep, or too wide for Concrete Mender. We have
even used solid Concrete Mender to support railroad weigh scales
for Burlington Northern.
2. Can I use Mender for an overlay?
Only in small areas. While it is possible to apply 10 Minute Concrete
Mender over large surfaces, we do not recommend the material for
general overlay use. The rapid curing nature of Concrete Mender
makes smooth coatings over a large area difficult. The material
itself was not designed as an overlay. Mender is excellent for
repairing floors before coatings are applied.
3. How about using Mender in a freezer?
Yes, 10 Minute Concrete Mender works great in freezers and coolers.
Use the same techniques that are used in normal floors with the
following exceptions. Keep the material and sand at room temperature
(70-80° F), allow for extra curing time. Contractors have
used mender in flash freezers (-30°F) with excellent results.
For detailed information call Roadware and ask for the Cold Environment
Application Techniques data sheet or visit our web site.
4. What is the shelf-life of Concrete Mender?
With recent changes in Roadware packaging and scheduling, over
90% of Roadware cartridges are packaged and shipped within 72
hours. That means you will always get fresh cartridges when you
order product. We guarantee the shelf life of factory sealed Roadware
products for one year when stored properly. Of course we rarely
find any cartridges sitting on the shelf that long. Roadware bulk
materials packed in steel cans will last for one year or longer
when stored in a cool dry place. Be sure to mix side "A"
and side "B" separately before use. Opened containers
should be resealed with a head of dry grade nitrogen to prevent
moisture contamination. Nitrogen is available from welding supply
dealers. You will need a tank, a regulator, and an air hose with
a trigger valve on the end. Just before resealing the cans, shoot
in a little nitrogen. Your Concrete Mender will be fresh and ready
to go for the next job.
5. Can I get extra instruction sheets?
Yes, many distributors sell partial cases of product. Roadware
wants every end user to have an instruction sheet. If you need
extra copies, call Roadware at 800-522-7623. We will send them
out ASAP.
6. Can we link our web site to your web site?
Yes, Roadware encourages distributors and customers to use our
Internet web site for the latest product information, specifications,
and MSDS sheets. We do not list distributors on our site so your
customers will remain yours.
7. Can 10 Minute Concrete Mender be air shipped?
Yes. Both 10 Minute Concrete Mender and Flexible Cement II are
non IATA/DOT regulated and nonhazardous. They may be shipped standard
air freight. We recommend using the original shipping containers
and including the MSDS sheets on the outside on the box with the
packing list just in case the box gets severely damaged and product
should leak out. Roadware UREASEAL is DOT regulated and must be
shipped in accordance with Federal and International regulations.
8. Where can I get sand for Concrete Mender?
Good sand can be found at most places that supply the sandblasting
industry. The best sand is dry white silica/sandblasting sand
with a gradation close to table sugar. For hairline crack repairs
a finer sand can be used. For larger repairs a courser sand will
work. Do not use play sand, beach sand or concrete sand. They
contain too much dust and moisture. If you do not have the proper
sand in your area, we can arrange for sand to be purchased and
shipped from the Chicago area.
9. Why the red cap on the Concrete Mender?
The red cap has three functions. It protects the cartridge when
it is out of the shipping case. It holds the flow restrictor in
place when packaged. And it can be used to catch drips from the
end of the mixer when moving from crack to crack.
10. Can I reuse the mixer?
Yes, Mender only. If you immediately remove the mixer from the
cartridge and empty it out completely, the mixer can be reused.
The same goes for the flow restrictor. With Flexible Cement II,
you can use the same mixer with multiple cartridges if you work
fast. This will reduce the small amount of material left in each
used mixer.
