Some Tools of Grind 1 Inch of Strong Concrete

Sledgehammer

Sledgehammer

When you think about grinding concrete, a sledgehammer comes to mind at the very beginning. As a sledgehammer has a long lever and a strong metal head, it is ideal for striking it with hard objects. It can be especially useful if the thickness of the concrete is not much. You can follow the following steps:

Procedure

Start from the edge. You can use a pry tool to try to lift the surface from the edge. Creating a space or void underneath the concrete will be a good option. You may need assistance who can help you with the pry tool. Start hitting from the edge and go towards the center. Keep using the pry tool to remove the broken or cracked pieces of concrete from the surface.

Precaution

Be sure to wear steel-toed boots, gloves, and goggles. Make a plan to dispose of the broken slabs so that they can be transported out quickly after the work is done.

Digging Bar

Digging Bar

A digging bar can very well be an option for grinding 1 inch of concrete. A digging bar is a long tool made up of metal with a sharp to blunt head. It is ideally used for breaking or loosening up material like soil, rock, concrete, etc. It is used by:

Procedure

Similar to a sledgehammer, start using the digging bar from the edge of the concrete surface. You may use a pry tool as well here. By creating a space or void using the pry tool, keep hitting the surface with the blunt end of the tool. Then you can use the sharp end of the digging bar to remove the cracked pieces of concrete. The use of hand-driven tools can be a very laborious job. In that case, power-driven tools are a better way of grinding concrete. Some power-driven tools for grinding concrete are given below:

Angle Grinder

Angle Grinder

An angle grinder can be a powerful tool in grinding concrete. It is a smaller electric handheld tool with an abrasive disc or a thinner cut-off disc. The grinder uses speedy blades, which is ideal for both grinding and cutting.

Procedure

A diamond blade is needed to cut concrete because of its toughness. The angle grinder must be held so that the blade faces out and the guard faces up. The grinder is to be moved back and forth along the surface to ensure you are cutting off enough of the concrete to get your desired 1-inch cut. Then, trimming should be done on the reverse side of the surface, which will ensure the protection of the visible surface. To make the process easier, you may mark the surface of the concrete using pencils.

Precaution

Be sure to wear goggles, a respirator, and some sort of ear protectors. Also, never use it without their guard or handle attached.

Edge Grinder

Precaution

Wear a mask and safety glasses as a concrete saw can produce a lot of concrete dust.

Jackhammer

Jackhammer

A jackhammer is a long drill-type machine used to pound the concrete ground to break it into smaller pieces. It is run by compressed air, although some use electric motors. Though it can be a little too powerful for getting the 1-inch grind, it can give the desired result if used carefully.

Procedure

While using a jackhammer, it is ideal to start from the edge. You can use a short blade for your use. The concrete must break right away with the strong power of the tool. After grinding for a bit, the broken pieces must be removed immediately, and then continue your grinding.

Precaution

The most important precaution you should take while using it is protecting the ear. Jackhammers can produce sounds up to 120 dB, which is harmful to the ear. Wear earmuffs or earplugs to protect your ear.

Chipping Guns

Chipping Guns

Chipping guns are handheld electrically powered tools that are similar to drill machines. The tool delivers rapid blows through chipping action. It can grind concrete.

Procedure

Hold the chipping gun at an angle. Use it thoroughly along the surface and repeat it from the other side, loosening the concrete rectangularly. Now, the broken pieces of concrete can be removed by using a chisel.

Work master Tool

Workmaster Tool

Work master is a large polishing and grinding machine. It has 8 head Oct-Disc and scrabbler tooling. It is used be maneuvering it with the help of two hands. Tight places can be reached and can be worked very close to the walls. This machine can take care of smoothness.

Procedure

By maneuvering with the help of two hands, it can cover the whole surface. This machine will require to go through the whole floor multiple times to get 1-inch grinding.

Rotary Hammer

Rotary Hammer

The rotary hammer is hand held electric tool that can easily grind the concrete surface. It is also similar to the hammer drill and uses spinning motion to break concrete.

Procedure

Choose an appropriately sized drill for your job. You can start the grinding process from any place you want on the surface; it does not have to be the edge.

The concrete will break into big chunks of concrete. The depth of the drilling can be controlled simply by pulling out after getting into the desired depth. Remove the concrete chunks after every 10 minutes of work.

Propane Concrete Grinder

Propane Concrete Grinder

Propane concrete grinder is easier to use than other electrical grinders because it does not need any cord to connect to its power source. If you are working outside where a power source cannot be accessed, a propane concrete grinder can be ideal for you. It generally comes as a walk-behind device and uses propane as its fuel.

Procedure

Just take the propane grinder and roll it over the area. You may need to grind the same spot multiple times as it removes the very thin layer of concrete at a time.

Ride-On & Double-Headed Floor Grinders

Ride-on & Double-headed Floor Grinders

Ride-on double-headed floor grinders can be used for large areas. It covers a large area of the concrete surface, and so the surface may be ground over a much shorter amount of time.

Procedure

Sit on the grinder. Use its steering to navigate yourself around the concrete surface to cover the whole area. You need to completely ride around the whole area of concrete multiple times.

Selection of Disc Attachments

To use various power-drive tools, especially the hands-on drills, selecting appropriate disc attachments is necessary. The following disc attachments are to be considered for grinding 1 inch of concrete.

Diamond Segmented

Diamond Segmented

Diamond cutting disc attachments can give you the best result if you look for proofing work or thin-film coating removal. Segmented can give the roughest cut. The other advantage of the segmented disc is that the segments between the blades give the blade the necessary air circulation during spinning to cool off. So, using the segmented disc, you can use the power-driven tool for a longer time than other types of blades.

Silicon Carbide Stones

Silicon Carbide Stones

Silicon carbide stone will provide you the cheapest and most efficient option in case of concrete grinding. Silicon carbide stone can produce fine to coarse finishing. It is ideal for finishing small areas. But for larger areas, it may not be so practical because its attachment tends to clog soon.

Tungsten Carbide

Tungsten Carbide

Though it is more expensive than silicon carbide stones, it provides more longevity with more speed and efficiency. The attachment in this type of disc uses carbide-tipped blocks.

It can grind away the thicker amount of concrete than the silicon carbide or segmented diamond disc, and so it is both time and energy-efficient.

Diamond Cup Wheel

Diamond Cup Wheel

The diamond cup wheel is specially designed for grinding dry concrete. They have Large Grinding segments with heat steel bodies which is good for durability. It is a low laborious way of grinding than any other method.

You can also consider some chemicals while grinding the hard concrete surface. The chemicals help to soften the concrete. As a result, it will be easier to remove the required amount of layer concrete later on.

Expanding Grout

Expanding Grout

Expanding grout is a chemical agent which is popularly used on rock and concrete. This type of agent helps in cracking the concrete or softening it up without any noise. It is also safe, easy, and effective.

Procedure

The expanding grout is to be used by mixing the dry mix with the required amount of water. The amount of water and the dry mix depends on the strength of the cement that is used for the concrete.

After mixing the appropriate amount, the mixture is poured on the concrete surface and allowed to set in. Once it is set, it will start to expand.

Due to its expansion, a lot of force will be produced on the concrete, and eventually, it will start to crack. It will be easier to use a power tool like a jackhammer or concrete grind cutter to grind off 1 inch of the concrete.
