Polishing and honing concrete to smooth shiny surface is a great way to give an old warehouse floor new life. Sometimes, warehouse floors are too damaged and worn to make polishing practical. Floors that are full of cracks and spalls will require a large amount of grinding and polishing to achieve an acceptable surface. Roadware 10 Minute Concrete Mender™ may be used to restore the concrete surface and reduce the time and expense of heavy grinding. The Microdweling™ action of Roadware 10 Minute Concrete Mender™ can penetrate the surface of the cracks and spalls, fill in all the low spots, and make the floor ready for polishing.

|Pitted, spalled and cracked surfaces may be unpractical to polish.
The first step is a light surface grinding to open up the cracks and remove any loose materials.
|An initial grinding with metal resin pads reveals cracks and spalls.
Roadware 10 Minute Concrete Mender™ and fine silica sand mixed in bulk is troweled into the surface over the entire area and allowed to set.
|Workers trowel Concrete Mender into place.
In about 10 – 30 minutes, the surface is polished using standard techniques. Roadware 10 Minute Concrete Mender™ will not gum-up polishing pads or smear into the surrounding concrete.

After grinding, all pitting, cracks and spalls are filled and a smooth surface is quickly restored.
|Concrete Mender repairs hold up perfectly during the polishing process.
After polishing, hardening and sealing, a beautiful polished floor is revealed.

Special thank you to International Roadware Distributor Join K&C in Seoul, Korea for submitting this project.
How often have you run into this problem? Industrial railings that have been split apart due to age, abuse, or weather damage. With a few special techniques, you can repair these problems with Roadware 10 Minute Concrete Mender™.
Clean the repair area with a wire brush or by sandblasting. Remove as much of the rust as possible. It is also a good idea to spray the the steel railing with a rust neutralizer.
Make a simple form out of blue foam board, and duct tape or most anything plastic. Do not use wood, Concrete Mender will permanently bond the wood to your railing base.I made that mistake years ago and had to chip, grind and sand the wood off the face of the concrete.
Make your repair by pouring 10 Minute Concrete Mender™ bulk mixed with sand in from the top. Allow to cure and finish the surface with a stone or grinder.
Add a quick coating of a latex cement coating and your finished. You may also make repairs around railings with Roadware Flexible Cement II™ if the railing is made aluminum and requires more thermal contraction and expansion properties.
In March, you donated the Roadware kit to bind the cracks at the Hope Alive! Clinic in Haiti. THANK YOU FOR YOUR GIVING AND KIND HEART.
We went to the Atlantic City airport with the msds. They refused to allow us to bring the tubes on the plane. (they really didn’t know how to read the msds sheets either)
Anyway, we shipped the package via Philadelphia-container-Haiti. It arrived in time for our July 8th trip.
We brought along a Pastor who is also a “concrete guy”. He stated that he had never worked with a product that was so easy and did such a great job. As you can see in the attached photos, the fissure is completely sealed. As I mentioned in our phone conversation, the epi-center of the quake was only 6-7 miles from our clinic. We even have 2 sets of tubes left over!! (the neighbors will benefit)
I do not know how to say thanks but to just say “thanks” . Your kindness has made a difference with Hope Alive Clinics and the Haitian people. visit www.hopealiveclinic.org for more pictures of the teams and clinic activities.
If you are ever in the Philadelphia area, please look us up.
Again, many thanks and God bless you and your great company.

Here is a crack repair project at the CVG Airport in Cincinnati, Ohio. The upper terminal deck developed cracks parallel to the construction joints. Roadware Flexible Cement II™ was used to repair the cracks in 2005. Here are some pictures of the project over the years.
Here is a photo of the CVG terminal deck as of June 2010.
Roadware Flexible Cement II™ was used the repair the crack on the right in 2005. The crack on the left was repaired with Roadware 10 Minute Concrete Mender™ for comparison.
Finished repairs in 2005. Roadware Flexible Cement II™ on the left. Roadware 10 Minute Concrete Mender™ on the right.
Repairs as they appeared in 2006 after one year on service. Both are holding well. The Roadware 10 Minute Concrete Mender™ on the right shows yellowing, but is still performing well. The Flexible Cement II™ is slightly lighter on color, but looks perfect.
Here is the same repair in June 2010. After 5 years on service, everything looks good.
This is a close-up shot of the Flexible Cement II™ after 5 years of service. The repair is still holding like the day it was installed. Roadware Flexible Cement II™ is a good choice for outdoor repairs in structural concrete. The semi-flexible properties strike a good balance between road toughness and just the right amount movement absorption.
The advances in decorative concrete coating and finishes for patios, sidewalks, driveways and pool decks are amazing. All of these systems have one common element. They are all affected by the condition of the concrete underneath. We recommend and use Roadware Concrete Mender™ Off-white to repair cracks, spalls and surface defects prior to decorative concrete treatments and coatings. Off-white Mender is just like the Roadware 10 Minute Concrete Mender™ except it cures to a neutral off-white color that has less chance of affecting the color of the decorative coatings applied over the repairs. Take a look at the project below.
Here is a church with a spalled and rough looking entrance.
Prior repair materials were removed revealing worn, but sound concret
Roadware Concrete Mender™ Off-white and sand mixed in bulk is applied and troweled smooth. The material appears brown due to the brown colored manufactured sand added to the mix.
Cracks are cleaned and repaired with cartridge applied Roadware Concrete Mender™ Off-white and sand.
After about 15 – 30 minutes, the repairs are ground smooth and flat. The concrete is now ready to accept most types of decorative concrete treatments.
Roadware Concrete Mender™ Off-white is compatible with most high-build overlay or coating systems. It is also recommended by several top coating system manufacturers.
Today I received several photographs of a large crack that developed under a hardwood floor in a slab-on-grade application. The crack buckled the hardwood flooring. The home owner consulted several contractors and engineers to solve the problem. No cost-effective solution could be found until Roadware contractor, Clay Kenny, (Manderville, Lousiana) arrived on the scene.
Using Roadware 10 Minute Concrete Mender™ and silica sand, Clay repaired the crack to full depth and re-bonded the slabs back together using Roadware’s Microdoweling™technology.
The repairs cured in just 10 minutes and Clay was on and off the job in just 3 hours. The home owner was amazed. Clay and 10 Minute Concrete Mender™ did what couldn’t be done. The hard wood flooring was re-installed and the floor was put back in service faster then anyone could imagine. This repair took nine 600ml cartridges of #80300 Roadware 10 Minute Concrete Mender™ and a 40 lbs bag of silica sand to complete. The Concrete Mender™ turned a flooring disaster into an opportunity.
Anyone in the concrete business knows that concrete can be unpredictable and even a well thought-out project can develop cracks. Some are minor, and some can cause a real problem. Roadware 10 Minute Concrete Mender™ can help make the problems manageable.
