Grind It Down

Concrete floors have become very popular offering many advantages such as durability, versatility and easy maintenance.  They are long lasting and can survive under high traffic conditions.  Concrete slabs also make a good sub-floor for laminate floors, tile, linoleum, carpet and other applications.  Essential for a new slab or the repair and/or reconditioning of an existing floor is surface preparation.

Surface preparation equipment is used to polish or grind concrete surfaces or to remove previous treatments.  If your job requires leveling uneven joints or surfaces, eliminating trip hazards, or the removal of coatings, adhesives or mastics – then a concrete grinder is the tool you need.

When choosing a concrete grinder, the first thing to consider is what you are planning to use it for and the size of the job you will be doing.  Let’s take a moment and look at the different equipment rental options for preparing or grinding a concrete surface.

Surface Grinder

Surface Grinders:  Concrete floor (surface) grinders are used for applications such as grinding or cleaning concrete surfaces, leveling uneven joints & removing epoxies, high spots, mastics, thin-set & urethanes.  We offer a full line of grinding tools & conventional attachments including Grinding-Stones, Dyma-Serts and Strip-Serts to meet your surface preparation needs.  Surface grinders work well for light grinding or cleaning of concrete surfaces.  If you have a significant amount of concrete to grind (say more than ¼”) you’ll have to make several passes with the machine.  If the dual-headed concrete grinder is too big, consider renting a 16” heavy-duty floor machine with the grinding attachment that uses the same attachments as the dual-headed floor grinder.  The 16” floor machine also has a sanding attachment as well as a scrubbing brush attachment for cleaning a floor.

Scarifier

Scarifier

 Scarifier:  A scarifier is a surface preparation machine that will clean, texture, level, groove, and remove material from concrete flooring.  Scarifiers remove concrete faster and more aggressively than surface grinders as they use the pummeling action of multi-tipped cutting wheels, or flails, that rotate at high speeds to chip away at the concrete surface.  Keep in mind that scarifiers leave a rougher finish.  If you need a smooth finish you will need to use a concrete floor grinder to achieve it.

Teq-Edge Floor Grinder

 Teq-Edge Floor Grinder:  The Teq-Edge floor grinder is a very versatile surface grinder that uses an 8” diamond disc to grind the concrete.  The Teq-Edge is designed to get into tight or hard to reach spots, including being able to grind up to the edge of a wall.  The diamond disc allows for fast grinding of uneven slab surfaces, removing excess surface material, leveling patches of plastic overlays or grout and feather-edging sidewalks, gutters and similar surfaces.

Hand Grinder

 Hand Held Grinders:  These are ideal for small jobs like areas close to walls and other hard to get places.  They are also ideal for removing blemishes to concrete work.  They are very light and easy to use.  Our hand held grinders can be outfitted with either 4” or 7” abrasive grinding wheels or with a 5” silicone carbide grinding cup stone.

 Safety First:  Please remember that all cement products contain sand.  When that substance is released in the air, as will happen when using a power tool on concrete, the operator of the machine will breathe it in if a dust mask or respirator is not worn.  Concrete dust can cause long-term health problems for the operator or anyone else who breathes it.  Always wear a dust mask or respirator and safety goggles to protect your eyes and lungs from the dust that will be released by the removal process.

Does your concrete project require more finesse than simply breaking up the concrete with a jackhammer?  A cut-off saw, floor saw or concrete chainsaw may be the answer.  All three items provide the capability of cutting concrete and in some instances asphalt with control and precision.  Let’s take a look the capabilities of the different concrete saws available for rent.

 Cut-Off Saws

For most concrete cutting jobs, the cut-off saw is a popular choice.  These hand-held saws can be used to cut concrete, asphalt and metal.  Cut-off machines resemble a chainsaw, however they have a circular blade instead of a chain and bar.  Typically available in 12-inch or 14-inch blade sizes, cut-off saws can be powered by a two-stroke gasoline engine or an electric motor.  Abrasive (silicon carbide material) or diamond- rimmed blades are the most common saw blades for cutting concrete.  Both blades are used to cut or score concrete, with our 14-inch (blade diameter) cut-off saws able to cut up to four inches deep.  When used to “score” concrete, the “score line” allows for a nice cut-line when breaking out a concrete section.

 Concrete Chain Saws

While similar to a concrete cut-off saw, a concrete chainsaw is designed to plunge nose first into the concrete and has the ability to cut more than twice as deep as a 14-inch cut-off saw.  Concrete chainsaws provide a deeper cut with no over-cut, allowing you to make square corners, which is not possible with a cut-off saw.  They can be used to make openings as small as 4-inches by 4-inches and to cut odd shapes and sizes.

 Concrete Floor Saws

8hpconcretesawWalk-behind concrete saws or “floor saws” are used to cut sections of flooring or similar flat sections.  Our 14-inch saws will cut up to a depth of 4-inches.  This type of saw can be used for scoring concrete for slab removal with a jackhammer, making expansion cuts to new concrete slabs, and cutting asphalt.  These saws are gasoline powered and similar to the cut-off machines use either a silicon carbide abrasive blade or a diamond-rimmed blade.

 Diamond Blades vs. Abrasive Blades

As mentioned above, you have the option of using either an abrasive blade or a diamond blade when using a hand held cut-off saw or a walk-behind concrete saw.  The abrasive blades work well for small cutting jobs in concrete, asphalt, or even metal.  The downside to abrasive blades is that they wear as you use them (similar to a grinding wheel) so the blade life is much less than the life of a diamond blade.  Diamond blades allow for a faster cut and offer a constant cutting depth.  They are available for purchase or rent and are a much better value if your job requires a significant amount of cutting.  While we have dry-cut blades available, most of our diamond blades are “wet-cut” requiring water to keep the blade cool (which extends blade life) and the dust down.

 Safety First

With any project safety comes first.  The cutting of any material using power tools creates dust and flying chips.  We recommend the use of safety glasses with side shields or safety goggles, work gloves, a work apron or close fitting clothing, hearing protection, and an approved dust/mist respirator.
