Quartz epoxy is an excellent choice for creating a non-slip surface outside. The surface will be resistant to scratching and staining and has enough texture to prevent someone from slipping. You can use this system on ADA Ramps, sidewalks, or patios. Another added benefit of using this system is the color choices available, so you will still be able to achieve a decorative finish. Below is a photo of a concrete patio and stair we applied the quartz epoxy system to.

If you have a typical plywood second story and you are considering having concrete floors installed, there are a few things to consider.
First you want to make sure there are no extreme low spots in the plywood. If there are and if it is a older house you might need to reinforce the floor joist the plywood is sitting on. You probably should consider this with any other ceramic or stone floor also. The weight of concrete floors is about the same if not less then installing ceramic tile and hardi-board. So if second story in your house is qualified to accept ceramic tile on the second story you will be ok with having concrete floors.
The next thing is you should not use self-leveling overlay material to get your concrete floors. This material is brittle and will crack excessively when the plywood moves a little bit. If you need guidlines on how to install concrete floors on a second story follow the link http://mvlconcrete.com/blog/upstairs-concrete-overlay-acid-stained/ . If seen many people try to use self-leveling material and then they have a huge mess to clean up when it fails.
The first concrete floor we did on a second story was about 5 years ago, and so far there has not been any major cracking. There are a few hairline cracks that are not opened up; you mainly see the crack because of the color on the surface. So don’t expect the concrete floors to have minor cracking.
If you have any questions or are looking for someone to install concrete on the second story of your house please feel free to email me at firstname.lastname@example.org or call 210-422-6116.
If you have vertical or horizontal cracks in concrete your best method to seal them would be to use an epoxy crack injection kit. Sealing the cracks in concrete will help prevent water from soaking in and causing harm to the rebar.
The first step when rehabilitating concrete using the epoxy crack injection method is to use an epoxy paste to close the outside of the crack. While doing this you will also install injection ports approximately every 8″ apart. Sealing the outside with a paste will help prevent the lower viscosity epoxy from spilling out when you are injecting into the ports.
Once the epoxy paste hardens fully you will use a caulk gun to dispense low viscosity epoxy into the concrete starting at the lowest point. The low viscosity will allow the epoxy to penetrate deep into the concrete bonding everything back together.
After letting all of the epoxy cure you can chip off the ports and grind any excess epoxy flush with the concrete.

Epoxy flooring is the best flooring option for commercial kitchens. Epoxy flooring does not have joints like tile that will get filled with grease an will be hard to clean. There are many epoxy systems to pick from to fit the needs of the kitchen. The systems range from basic two coat applications to troweled down epoxy mortar systems for a very long lasting floor.

Are you a DIY’er and need new flooring in your house? Stained concrete is the easiest flooring option for DIY project. When staining concrete you do not need any saws or special equipment. All you need is some safety protection gear and a pump up sprayer.
The hardest part about staining concrete is getting the color close to what you are looking for. The only concrete staining tip I can give you on colors is to always start with a strong dilution, meaning dilute the stain with a lot of water (if it is a water based stain) to make it lighter. You can always make the concrete floor darker, but once you have made the floor to dark you will not be able to lighten the color. You also want to consider what the floor will look like when it is sealed, most sealers will darken the floor.
Other then getting the color close to what you are looking for, staining the concrete is nothing more than spraying the concrete down using a pump sprayer with the stain in it.

How do you repair alkali silica reaction in concrete? I wish there was a simply solution to achieving that. I had a homeowner call and tell me she was having small modules of gel leaching out of the concrete, and over time the gel would harden. She had an engineer come out and take samples of the concrete, they determined that she had alkali silica reaction or (ASR).
So I went over to the house to take a look at the problem and was amazed by what I saw. Take a look for yourself:
Alkali Silica Reaction
I’m sure you can figure out why this might be a problem. For starters she has a decorative overlay in the house that is peeling off because of this reaction. She also has sticky gel all over her floor which makes it difficult to keep clean. She asked if there was any way to prevent the gel from re-appear.
I asked a couple of different suppliers and manufactures about what can be done to stop this. For the most part they all told me the concrete has to be jack hammered out and re-poured, which is not feasible because the house is already built and she is living in it. One person told me I can use a product called Aqua Block and that might help.
I told the homeowner I would not mind messing around with it seeing if anything will help the situation. I suggested to grind the concrete down where the ASR was happening, which happens to be where all of the structural beams are. After grinding the concrete I left one area untreated and another area I treated with Aqua Block to see if that will help at all. After a couple of months I will go back and check to see if their is any improvements. If anyone has any suggestions or questions on this issue please email me at firstname.lastname@example.org.

This last week we got a job consisting of removing VCT flooring and then staining the concrete afterwards. The building was an older building so the chance the mastic under the VCT contained asbestos, so we decided to strip the mastic off instead of using the grinder.
After we stripped the mastic off we had to clean the concrete with a floor scrubber and degrease the floor because of using a soy bean based mastic stripper. We then acid stained the concrete using the color cola and then sealed the concrete with a solvent based sealer.
Spalling concrete can be a major issue in parking garages. Unlike concrete buildings that receive a curtain wall protecting the inside concrete floors from the weather, parking garages are open to the elements of the weather. Since the concrete parking decks are opened to the weather is it especially important to place the rebar in the correct locations and have enough concrete covering them.
A protective treatment that can be done to the parking deck after the concrete has been poured is to apply a waterproofing membrane to the concrete. This membrane will prevent water that is sitting on the concrete parking deck to leech into the concrete causing the rebar to corrode causing a spalled area. This membrane can be applied right after the concrete has cured or years after. This investment will protect the parking garage from future spalling problems that could potentially harm a pedestrian.

If your looking for a matte finish concrete floor that is easy to clean, then consider honed concrete for an option. Honed concrete is achieved by grinding the concrete to an even texture and then smoothing the surface with finer diamond pads. We typically stop at a 200 grit pad for honed concrete, if you wanted a polished surface you would continue to the next polishing pad. Honed concrete is beneficially because the duller surface wont show as much dust and dirt as a highly polished surface would. Honed concrete is an excellent choice for exterior patios and walkways. Take a look at the pictures below of an interior concrete floor that is honed to a 200 grit.

This week we had a job that consisted of removing tile and then polishing the concrete underneath the tile to create a modern concrete floor. When we started removing the tile floor we realized the tile was sitting on a mud-base that was 2″ thick. Instead of removing the tile and the mud-base we prepped the tiles to receive a self-leveling cement topping. After we poured the new concrete floor we sealed the floor with a water base sealer.
