You can use MatchCrete™ Clear Concrete Repair Polyurethane to repair intregal color or stamped concrete.
Remove dirt, loose concrete, repair materials or failed caulk.
Use a diamond blade to slightly cut open the crack and clean out loose concrete and debris.
Use tape to mask off the crack.
Gather materials needed to make the repair. From left to right we have some brown concrete pigment, silica sand (43-30 grit), black unsanded tile grout for color, and a mixing cup.
Dispence the MatchCrete™ Clear into a cup.
Add a littlt silica sand to give the MatchCrete™ Clear some base color.
To create your color, add a small amount of powdered concrete pigment and blend with a mixing stick.
Concrete pigments are strong. It just takes a small amount to color the product.
Here we are adding some black un-sanded tile grout to the mix to make a closely matching color to the stamped concrete. You can use many types of sand and dry pigments to create the desired color and texture.
Blend well by hand for about 30 seconds. You will have about 10 – 15 minutes of working time before the product starts to gel. Work in small batches.
Pour the blended MatchCrete™ Clear into the crack. The material will start to gel and can be troweled into place before setting.
Allow to set for about 30 minutes and pull the tape.
The repair can will be ready for traffic in about an hour. Roadware MtchCrete™ Clear repairs are tough and will not crack apart like cement based materials. The repair is UV color stable and will not become brittle like epoxy. Please click here for a MatchCrete™ Clear data sheet.
Stop repairing polished concrete with polyurea joint fillers. They look like plastic, do not bond well, and do not hold-up over time. Concrete polishing lets the natural beauty of stones, sand, and rock shine through. Your repair product should as well.
The repair pictured above shows Roadware Concrete Mender™ Off-white blended with plain concrete sand and a small amount of portland cement. This water-thin polyurethane is almost translucent. When we add nearly any type of dry sand or aggregate, we get a fast-curing polishable repair that blends beautifully with the surrounding concrete. Since this material is almost translucent, it resists shadowing effects due to over-banding when applied.
One of the most common calls we get is asking how to repair a crack in a driveway or patio. We designed Roadware MatchCrete™ Clear with this in mind. Roadware MatchCrete™ Clear is a UV stable clear polyurethane hybrid that makes effective repairs to most exterior concrete surfaces. By simply leaving the repair clear, the color of the surrounding concrete shows throughout the repair.
The first step to a good looking crack repair is to rout-out or cut the repair open with a diamond blade grinder. You only have to go about 1/4″ x 1/4″. This will create a recess for the material to rest as it soaks down further into the crack. Skipping this step will allow the material to flow uncontrollably on the surface and will create a messy looking repair.
Apply cartridge mixed MatchCrete™ Clear directly to the crack. Small amounts of silica or quartz sand can be added to keep the material from flowing out the bottom of the slab. If necessary, matching colored sand can be used to match colored concrete areas. Fill the crack to slightly below grade to prevent material from flowing on to the surface of the concrete.
After a year of service, the repair above still looks good. Please note, MatchCrete™ Clear is not a soft expansion joint material and should not be used in joints that are designed to move. Always give careful consideration as to why the concrete cracked in the first place and what the concrete is expected to do in the future before making repairs of this nature.
We have a new video for driveway hairline crack repair:
This week the City of Minneapolis used Roadware MatchCrete™ Clear to repair cracks in the exposed aggregate walkway surface on the Stone Arch Bridge in Minneapolis, Minnesota. The Stone Arch Bridge is unique to the Mississippi River and features 23 arches, is 2100 feet long and 28 feet wide.
The bridge was built by railroad baron James J. Hill in 1883 and served as a working railroad bridge until 1965. Today the bridge is mostly used by walkers and bicyclists. The bridge also hosts many festivals and public events in the summer months.
In preparation for the summer festival season, City of Minneapolis crews used Roadware MatchCrete™ Clear to repair cracks in the exposed aggregate walkway surface. MatchCrete™ Clear is combined with matching rock to repair cracks and restore a consistent walking surface.
The process begins with routing out the cracks with a dry diamond blade
to remove loose dirt and debris. Clean and dry matching stone is placed
into the crack up to surface level.
Matching stone is added up to the surface level
Next, two-part blended MatchCrete™ Clear is poured into the repair up to the surface. This fills in all the voids between the stones and seals the crack. MatchCrete™ Clear is a semi-ridged material that will support all kinds of traffic from pedestrians to industrial fork lifts.
MatchCrete™ Clear is added to the pre-placed stone
See video MatchCrete™ Clear application video below:
Repairs will have a, wet” look for a few months and will naturally dull over time. A clear coat sealing over the entire surface will off-set this effect.
MatchCrete™ Clear repair in exposed aggregate concrete.
In a few months, Repairs with MatchCrete™ Clear will dull and blend into the surrounding concrete.
Over time, repairs will become less shiny.
Update: June 24, 2012.
MatchCrete™ Clear repairs 18 days later.
I revisited the repairs on the bridge 18 days later. The surface has been sealed. The repairs are performing as expected.
Roadware MatchCrete Clear is available is 50ml and 600ml cartridges and two gallon bulk kits.
