14floorpolisherA question we hear a lot is “what is the difference between a Floor Polisher, Floor Machine, Floor Buffing Machine, Floor Scrubber or Floor Stripper?” The answer is “nothing” – they are all the same machine!

At Bunce Rental, we refer to these machines as “Floor Polishers”. You will also see a floor polisher referred to as a “Swing Machine” due to the swing motion the machines have when you operate them. As you can imagine, they are very versatile units. We carry a number of attachments to meet a variety of needs for caring and working on your floors. This includes buffing and scrubbing pads, polishing and scrubbing brushes, floor sanding, and concrete grinding or surface prep attachments.

Pads and Pad Drivers

Using pads with our floor polishers will allow you to do one of three things – strip, clean, or buff your linoleum, tile, and vinyl type floors. An industry standard color-coding system for low-speed floor pads can help you select the right pad for your job. In general, the lighter the pad color, the less coarse or aggressive the pad. We stock pad colors in white, tan (beige), green and black.

Buffing pads (white/tan) are lightest in color and remove scuff marks and dirt from floors. Cleaning pads (green) are designed to clean a little more aggressively than buffing pads, and remove dirt off a floor’s surface without removing the floor finish. Slightly more aggressive than cleaning pads are scrubbing pads (black). They will remove the top layer or two of wax, along with scratches and dirt.

There are also a variety of different chemicals you can use with the pads to help you accomplish your purpose. Check with your local cleaning supply store to learn what chemicals work best to clean, strip or polish your floors.

Brush Attachments

Brushes are used to clean and/or wax the floors. Like the pads, they can be used with chemicals designed to clean or polish the floors. They are available with bristles of varying stiffness and abrasiveness, depending on whether it’s to be used for scrubbing, buffing or stripping.

Grinding Attachments

Grinding attachments are designed to turn the floor polisher into a concrete grinder. Like the concrete grinder, the grinding attachments can use grinding stones, strip-serts, and dyma-serts. The uses and applications for these attachments are outlined in our previous blog post, “Not All Stones Are Created Equal.

Sanding Attachments

Sanding attachments turn a floor polisher into a 16” disk floor sander for sanding and refinishing floors and decks or removing material (paint, texture etc.) from concrete. With a variety of grits of sandpaper available, you can just lightly refinish your floors with finer grits or sand rougher areas of the floor smooth.

Safety First

Basic safety rules should be followed when using a floor polisher. Always use safety goggles and do not wear loose fitting clothing while operating the polisher. Never leave a floor polisher plugged in when unattended and do not store the polisher with the pad/brush on the machine.

Do not operate a floor polisher near flammable fluids, dust or vapors – this could cause a fire hazard. If using floor cleaners and waxes, ensure that they are intended for machine application and understand all information printed on the product Safety Data Sheet.

Not All Stones Are Created Equal

Sometimes a grinding stone isn’t the only or best solution when using our concrete surface grinders.  Available in various grits for coarse or fine polishing, Silicon-Carbide Stones are an economical choice for such applications as smoothing trowel marks or rough finishes and leveling high spots less than 1/16 inch.  However, these stones can clog easily, which can make them inefficient at removing most coatings.

Tungsten-carbide inserts (Strip-Serts) and diamond grinding inserts (Dyma-Serts) remove surface coatings with greater speed and efficiency.  Strip-Serts are carbide-tipped blocks with beveled edges that can strip heavier buildups or coatings without digging into the concrete.  Their removal action, which is similar to using a scraper, works best in materials thicker than 1/16 inch.  Applications include removing adhesives, thick paints, resins, tar, industrial buildups and rubber deposits.  For profiling work and removal of thin-film coatings or coatings with high hardness values, such as urethanes and epoxies, Dyma-Serts are generally the best solution.

With the right tool, our concrete floor grinders can remove a variety of coatings and chemicals as well as create other textures or effects.

Because our friends at EDCO, Inc. explain the differences between the tools and their applications so well, we encourage you to check out their web page for more information on Strip-Serts, Dyma-Serts, and Grinding Stones,  http://www.edcoinc.com/accessories-floor-grinder.html#1

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.

Three Cubic Foot Concrete Mixer Electric

Three Cubic Foot Concrete Mixer Electric

You’re ready to pour that concrete slab for your new patio, hot tub, or storage shed.  Depending on the size of your slab, ordering a concrete truck may be overkill or a portable concrete mixer may not be enough to handle the job.  Today’s blog will cover the different concrete mixer and mixing options available from Bunce Rental.

Concrete Mixers

A concrete mixer combines cement, sand or gravel and water to make concrete.  Mixing concrete by hand, without using a concrete mixer can be pretty grueling and challenging work.  Portable concrete mixers are perfect for any small or medium sized job.  They are easily operated by one person and can easily be moved from one place to another.  We rent different types of portable concrete mixers: electric 3 cubic-foot mixers, which are stand mounted or towable, gasoline powered 9 cubic-foot mixers.

The principle behind both the portable concrete mixer and a concrete truck is the same.  The revolving of the drum mixes the ingredients together and then keeps the concrete from drying and hardening.  Port able concrete mixers are described in terms of drum capacity.  So a 3 cubic-foot mixer has a drum capacity of 3 cubic-feet. Batch output capacity is a different measurement.  While a concrete mixer might have a 3 cubic-foot drum, its actual batch capacity will only be around 1-1/2 cubic-feet.  So, don’t go only by the size of the drum, as when mixing concrete the drum will be at an angle and will only be 2/3 full.  The electric mixers come with a stand, which enables the mixer to be upright, allowing you to mix a pretty full drum load.

Nine Cubic Foot Concrete Mixer Gas Powered

The 9 cubic-foot towable mixer is a heavier duty machine.  As the name implies, they can be towed behind a vehicle and used for different jobs and in different locations.  A gasoline motor powers them and the drum has an attached lever that allows the drum to tip down and the concrete to pour into a wheelbarrow.

U- Cart Concrete

For projects that require larger loads, but not enough to justify having a truck deliver the concrete, check out our U-Cart Concrete.  Our professional concrete blending system is capable of producing up to 15 yards of ready mixed concrete per hour.  Using your ¾-ton truck or larger tow vehicle, take one of our tandem-axle mixing trailers with up to 1-yard of concrete to your jobsite; back up to your form and using the built-in hydraulic jack, place the concrete right where you need it.  While 1-yard of concrete may not sound like a lot – most people don’t realize that mixing just one yard of concrete would require over 40 bags of sack concrete.  What a great way to save time and money!

IMG_8897U-Cart Concrete is available for purchase at our Tacoma, South Hill Puyallup and Parkland / Spanaway locations.  Our concrete is made with premium-quality Portland type II cement and a premixed sand and 5/8″ pea gravel aggregate.  Since a trailer with a full load of concrete weights over two tons, we recommend at least a ¾-ton pickup for towing and a receiver hitch rated for 6000 pounds with a 2″ ball.  Remember, the maximum towing speed is 35 mph due to the weight involved.  You should have all site preparation done before coming to get concrete, and it is best to dump the concrete immediately on arrival at the jobsite, especially in hot weather.  If you are unsure of how much concrete you need, our online concrete calculator can do the math for you.  To use our online calculator or learn more about our U-Cart Concrete systems, go to our website at http://buncerental.com/concrete-sales.asp
