Enjoy the Ride with the NEW Rover Ride-On Floor Grinder from CPS

Why walk when you can ride? Runyon Surface Prep is proud to offer the newest equipment innovation from CPS at its Carmel and Rancho Cordova locations. Runyon Surface Prep is now accepting orders for The CPS Rover, a propane-fueled, ride-on concrete grinder with major power and incredible ease of use.

Years of experience in the industry led David Padgett, CEO of Concrete Polishing Solutions, to look for an equipment-based solution to employee exhaustion and labor costs that wouldn’t sacrifice the quality of the end product. The Rover was born.

“While Remote-Controlled grinders available on the market improve worker exhaustion, the disconnect between operator and grinder can lead to poor end results for the customer, as well as an increased chance of machine damage, because the operator can’t ‘feel’ the performance of the grinder,” explains Padgett. “The CPS Rover changes everything.”

The American-Made CPS Rover is a zero-turn, propane-fueled grinder with a 32” path, perfect for many applications. From the operator’s seat, there is clear visibility of all points on the machine. The precise hand-control and cordless operation makes The CPS Rover the ideal machine for jobs big or small. An onboard electric head lift makes for easy tooling changes and transport, while onboard electric generation allows for adjustable lighting. An on-board water sprayer allows for easy wet grinding.

Combined with CPS’ range of diamond tooling, available at Runyon Surface Prep in both Indiana and California, the CPS Rover delivers on power and quality while minimizing operator exhaustion, allowing contractors to save time and earn more. Runyon offers the full line of CPS products, including the G320D Propane floor grinder, metal bond and resin diamond tooling, spare parts and tool holder plates. Please let us know if you’re ever wanting for anything. We can even schedule one-on-one training or a demo of this new machine with our CPS rep and your crews. Contact us for more info!


The Importance of Surface Prep for Decorative Epoxy Flooring

One of our customers in Florida, Artistic Surfaces, is a prime example for how important it is properly prep your concrete before putting down a coating – whether it be an epoxy, overlay, etc. Below are four different epoxy jobs that their crew completed recently, courtesy of Sam Godbey, the Director of Operations at Artistic. The pictures don’t do them complete justice, but it is very evident surface preparation played a major role, and we were happy to have a part in that.

Charcoal Metallic Floor

This 3,600 square foot charcoal floor is owned by a high profile client. It’s a private residence, used to store the owner’s cars, sports memorabilia, and other appropriately coined “toys”.

Artistic prepped the surface with an HTC 800, Ermator T8600 and 25 grit HTC diamonds. This is a grey epoxy with a combo of Sterling, Onyx and Quick Silver metallic pigments.

Harley Quinn-esque Floor

This blue and pink metallic floor looks like cotton candy. It is located in a residential dressing room. Artistic partnered with Coastal Construction for this job.

They prepped the surface with an HTC 500 and 25 grit HTC diamonds. It’s an epoxy with black pigment base and metallic pigment colors Surfs Up and Merlot.

Black & Aluminum Striped Bar

This black and aluminum striped floor is located in a 5,500 square foot bar called the Escape Lounge. The epoxy was poured with a black base and then the aisles were taped out in a curved design and colored with Aluminum metallic.

An HTC 800 and 25 grit diamonds were used to prep the surface. Artistic also used CTS Rapid Set TRU self-leveling overlay in the back of the bar. The black portion of the epoxy floor was pigmented with Jet Black metallic and the stripes were pigmented with Aluminum metallic.

Intricately Designed Office Floor

Artistic recently re-did their 1,300 square foot office floor. They cut off the old white overlay and transitioned it to an epoxy metallic floor. They kept the same detailed saw-cut design work.

To prep the surface, Artistic used a 60 grit screen and floor buffer. This epoxy floor required a myriad of metallic pigment colors for all the intricate designs: Copper, Butterscotch, Merlot, Mother-of-Pearl, Surfs Up, Rose, Maui and Jet Black.

After putting down the metallics, they used a regular blade and v-blade to re-cut the saw-cut designs. Then they filled the cuts with black grout. And finally, they re-sanded the floor and put down 2 clear coats of epoxy.

About Artistic Surfaces

Artistic Surfaces was founded in 1989 by Harvey Namm after 25 years’ experience in flooring. The Company soon became an award winning flooring contractor in the Florida market installing flooring in stores like; Macy’s, Bloomingdales, Burdines, and Saks 5th Avenue. Luxury hotels, Art Galleries, Airport Terminals, Performing Arts Centers, Sporting Arenas and other venues were added as the years passed.

In the winter of 2009, Artistic Surfaces launched a new division for decorative concrete. This new division will capitalize on the emerging demand for interior and exterior decorative concrete flooring. This new division marked the company’s entry as the area’s most experienced design applicators for decorative concrete concepts.

The Time is Now to be OSHA-Ready for New Crystalline Silica Rule

The Occupational Safety and Health Administration (OSHA) has issued a final rule to curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in America’s workers by limiting their exposure to respirable crystalline silica.

The new OSHA regulation, Respirable crystalline silica, Section 29 CFR 1926.1153, took effect on June 23, 2016. Industries have one to five years to comply with most requirements, based on the following schedule:

Construction – June 23, 2017, one year after the effective date.

General Industry and Maritime – June 23, 2018, two years after the effective date.

Employers who fully and properly implement the engineering controls, work practices and respiratory protections are not required to measure respirable silica exposures to verify levels at or below the PEL for workers.

For contractors, this means now is the time to make sure your equipment will comply.

OSHA Enforcement Table

(Fine information supplied from Contractor Supply Magazine)

About 2.3 million workers are exposed to respirable crystalline silica in their workplaces. This includes 2 million construction workers who drill, cut, crush or grind silica-containing materials such as concrete and stone, and 300,000 workers in brick manufacturing, foundries and hydraulic fracturing.

Who Is Affected?

Anyone working on a construction site who creates or is exposed to silica dust in the course of performing work, including, but not limited to:

  • Grinding
  • Drilling
  • Barrel mixing
  • Edging
  • Cutting block
  • Sweeping
  • Shot blasting
  • Hand Grinding
  • Scarifying
  • Drywall sanding
  • Demolition
  • Precasting
  • Bricklaying
  • Broom sweeping

Key Provisions of the New Crystalline Silica Rule

  • Reduces the permissible exposure limit (PEL) for respirable crystalline silica to 50 micrograms per cubic meter of air, averaged over an 8-hour shift.
  • Requires employers to use engineering controls (such as water or ventilation) to limit worker exposure to the PEL; provide respirators when engineering controls cannot adequately limit exposure; limit worker access to high exposure areas; develop a written exposure control plan, offer medical exams to highly exposed workers, and train workers on silica risks and how to limit exposures.
  • Provides medical exams to monitor highly exposed workers and gives them information about their lung health.
  • Provides flexibility to help employers — especially small businesses — protect workers from silica exposure.

New Exposure Limits

New Silica Exposure LimitsChanges to the Permissible Exposure Level (PEL) of respirable crystalline silica is 50 micrograms per cubic meter of air (50μg/m3) at an 8-hour, time-weighted average (TWA) under any foreseeable conditions. The Action Level (AL) is 25 ug/m3 (0.025 mg/m3). You are at risk if the dust you breathe during an eight-plus-hour shift contains more RCS than the accessible amount, which is much smaller than a penny. 

How to Choose a HEPA Vacuum

  • High quality HEPA filters that are tested and certified, with a rating of at least 99.99 at 0.3 micron
  • 25 CFM per blade is required for hand grinders
  • High CFM & Water Lift for proper matching to equipment
  • Must have a mechanical filter cleaning method that is contained and allows no dust to escape
  • Multi levels of filtration, including a cyclonic chamber, pre-filters, HEPA’s and pre-separators
  • Drop down bagging containment systems, no dust can or tray
  • Availability to attach tools for collection at the source
  • Wet and dry availability when needed

Surface Profile Inspection Guide from SP1 to SP10

A surface profile of concrete or asphalt is a number associated with the material’s desired roughness or texture and its general appearance. It helps in determining if the surface is fit for a specific purpose. Roughness can be an indicator for:

  • Wear-ability
  • Friction coefficients
  • Performance in terms of cracks or corrosion
  • Adhesive properties

Our Surface Profile Inspection Guide helps in determining the desired surface profile of your concrete or asphalt and indicates the proper diamond tooling and machinery required for achieving it during the preparation process.

Surface Profiles (SP1-SP10)

The lower the surface profile (SP) number (SP1), the flatter the surface. An SP10 rating is an extremely rough surface. An accepted definition of surface profile is “the average distance from the peaks to the valleys of the surface, as seen through a cross-section of the prepared substrate.” The range of variation with your specific concrete slab, substrate or asphalt depends on its strength, composition, aggregate and finish. The final surface must allow for the secure mechanical bond of any sealer, coating or marking material, so make sure the surface is free of any dirt, oil, films, paint, coatings, cure, sealer and any other material before creating your desired surface profile.

Runyon Surface Prep carries a full line of HTC, Husqvarna, and CPS grinders, Edco scarifiers and scabblers, National floor scrapers, diamond tooling, carbides, scrapers and shot blasters for use in surface preparation.

Concrete Polishing Solutions Diamond Tooling Guide

Runyon Surface Prep is an authorized distributor for CPS (Concrete Polishing Solutions), offering floor grinders and diamond tooling for a variety of floor surfaces. CPS researches new equipment, diamond tooling, chemicals and more for use in the polished concrete industry. For more than a decade, the company has been committed to developing the tools contractors need to complete every flooring project successfully.

CPS Diamond Tooling Guide

To help in choosing the correct CPS diamond tooling for a number of grinding or polishing jobs, we’ve put together a one-page, full-color CPS Diamond Tooling Guide outlining seven of the most common removal and polish jobs, the right tooling, recommended machine speeds for each job and the average production per hour that contractors can expect.

Attributes of CPS Diamond Tooling

CPS Black Series (first 3 tasks): Black series metal bonded tooling is a traditional trapezoid-type tool that is soft bond. Life expectancy is an average of 8,000 to 10,000 square feet. Available in 6,16, 30/40, 60/80 and 150 grits.

CPS MACH Series (task #4): The CPS MACH series tooling cuts like resins and wear like metals. They don’t glaze up on hard concrete and can replace metals on 90 percent of floors. They are built tough, with an 8,000 square foot life span, increasing production over 100% as compared to dry metal bonds on hard concrete. MACH tools need no water, taking on hard concrete and grinding down to exposed aggregate if needed.

CPS Sektors (last 3 tasks): CPS Sektors are one-size-fits-all tooling that works equally well on soft, hard or medium floor surfaces. Sektors combine reduced labor costs with excellent tooling life to create the lowest cost per foot dry polishing system on the market.

Instructional Video – Get to Know the HTC 800 Classic Floor Grinder

The HTC 800 Classic is a powerful, robust machine that is very easy to operate. The Classic model is fitted with the extremely reliable neb hub system, which reduces the need of service and maintenance. Other features include:

  • 15 HP motor fitted with three grinding discs
  • Machine size handles large grinding areas, delivering high performance while being easy to handle
  • Grinding pressure is controlled using movable weights
  • Economical in design and use

Watch this video for a comprehensive, hands-on introduction to the HTC 800 Classic Grinder. Surface Prep’s own Dan Knuth demonstrates how it operates, important information about the grinder and how to troubleshoot common problems with the grinder. Below is a written overview.

Planetary, Counter-Rotating Grinding Feature

The 800 Classic uses a planetary component where two different grinding motions work simultaneously. It is a counter-rotating grinder. The entire unit itself is turning counter-clockwise while each of the three satellite tooling heads turn clockwise.

Rigid & Flex Plates

Two types of plates can be mounted to the grinder.

  • Rigid Plate – an all-metal plate, there is no flex to it at all. Metal bond tooling, PCD tooling, any aggressive type of tooling that’s going to grind or cut should be mounted to a rigid plate.
  • Flex Plate – this plate has a little give to it, which is going to protect against any type of foul scratching. Resin-bond tooling and transitional-type tools used in honing stages of a project should be mounted to a ridged plate.

Mounting Diamond Tools on the Rigid & Flex Metal Plates

The 800 Classic uses HTC’s instant diamond tool change system called EZchange™, an ultra-fast system for changing diamond tooling. You will notice that there are six beveled shoes located around both the rigid plate and the flex plate. The back of each diamond tool is also beveled. There’s only one way each tool can be attached to the plate. Simply slide the slot of the tool over the wing of the shoe, lining up the bevels, until it will go no further. Then with a hammer or rubber mallet, gently tap the diamond in to secure it.

Changing Tooling Plates

Once all the diamonds are loaded, mount the plate onto the grinder. Simply line up the plate notches with the grinder notches and drop each of the three plates into place.

There are two ways to secure the plate to the grinder safely. 1) turn the middle key on the grinder completely, which will prevent that plates from sliding off. 2) Put screws in each of the six screw holes on the plate. The centrifugal force of the grinder will hold the diamonds in place, so there’s no concern with the tools flying off.

Shrouds: Floating Plastic & Flexible Rubber

The 800 Classic has two types of shrouds, depending on the age of the grinder. The newer models will have a floating shroud, which will automatically adjust itself to the floor and the height of the diamond tooling. It’s a much better design when it comes to controlling the diamond dust and automatic adjustment to the contour of the floor.

The other type of shroud for older models is the Velcro® shroud, which is attached to the grinder using a Velcro strip.

A couple of things you want to be sure of – since the heights of the diamonds change and the contour of the floor may change, make sure to check frequently that the shroud is sitting at the proper height. The shroud should be resting on the ground when you attach it to the grinder. If it’s too high, no vacuum seal will be created and the dust won’t be contained efficiently. If it is too low, the shroud can fold underneath the grinder and get chewed apart by the diamond tooling.

Changing the Weight of the Grinder

Three separate weights are added to the 800 Classic, which influences the downward pressure on the diamonds. Each weight is about 38 pounds and two of the weights can be removed to adjust the downward pressure. Each weight has two tabs in the back, two on each side and one in the front. When removing a weight, pull it away from the grinder motor for ease of removal.

Wet Grinding Water Container

A wet grind uses water in order to grind and polish, keep the diamonds cool and cut more efficiently. The water tank is located on the front of the 800 Classic in front of the electrical boxes, and has a hole at the top to fill the tank. A water line runs down, out of the bottom of the tank, carrying the water to the front of the grinder, where it is emptied out and used with the diamond tooling to make the cuts.

Powering the Grinder

The 800 Classic comes with a 50-foot cord that plugs in to the side of the electrical box. There’s only one way to plug it in. You’ll notice a notch on the plug that corresponds to a notch on the receptacle on the electrical box. Those notches line up, the cord slides into place completely, and the cord cover fits into a tab located on the electrical box. The grinder is plugged in properly when the three indicator lights at the top of the receptacle light up.

Accessing the Electrical Box and Computer

The electrical box is located in the back of the grinder. To open it, use the included key or a flathead screw driver to turn the locks on the top and bottom of the door panel. Inside are guts of the grinder – the inverter or computer. For any reason the grinder shuts off, a fault code will appear on the computer readout screen that corresponds to information located on the inside door panel or in owner’s manual. You can also contact Runyon Surface Prep and talk to one of our repair technicians or research online. Other information is included on the inside of the door panel as well, such as the unit’s serial number, electrical requirements, etc.

Grinder Control Panel

On the control box is at the top of the grinder and contains six buttons:

  • Emergency Stop (red) – cuts all power to the unit when activated. To restore power, depress and turn the emergency stop button until it pops up, and off.
  • Duty light (green) – next to the emergency stop button. Electricity is powering the grinder when lit.
  • Reset – clear any computer error codes by pressing this button.
  • Potentiameter – next to the reset button. Controls the speed of planetary rotation.
  • Forward-Neutral-Reverse – bottom left side of the control panel. Controls direction of planetary rotation. Please note: Correct rotation direction is important when using directional tooling such as PCD diamonds.
  • On-Off – after disengaging an emergency stop, turn the grinder back on here; the duty light should illuminate green, which indicates power has been restored and the grinder is ready to begin working.
