Properly Place Decorative Concrete Overlays in Extreme Weather Conditions

TRU PC Floor by National Concrete Polishing

Indoors and out, decorative concrete overlays permanently cover up surface imperfections in existing concrete, giving them any new look imaginable at a much lower cost than removal and replacement.

Today’s cement-based overlays combine polymer resins with cement, sand, acrylics or acrylic blends and other additives to improve performance, wear resistance, beauty and shine. They adhere well to existing concrete and resist damage from salt, chemicals, UV exposure, freeze-thaw conditions and abrasion.

The most popular types of decorative concrete overlays include stamped and stained concrete, and the popularity of other types varies in different areas of the country:

  • Exterior knock-down finishes are popular in the Sunbelt regions
  • Hard-troweled interior microtoppings are popular in metropolitan regions

With many options available, you’re sure to find at least one system that offers the most variety in color and finish while meeting your requirements for durability, appearance, maintenance and cost. Contractors must pay critical attention to adequate surface preparation, the most critical factor to long-term performance. For this reason, they prefer mechanical surface preparation, which does a more thorough job with the same grinding equipment and diamond tooling used for polishing concrete.

How to Concrete for Decorative Overlays in Extreme Weather Conditions

Concrete experts like the Portland Cement Association suggest contractors employ hot weather concreting procedures if the ambient temperature is forecast to exceed 77°F. Hot weather, high wind velocity and low relative humidity force higher concrete temperatures, which in turn increase the water-cementitious materials ratio, resulting in lower strength and reduced durability. Concrete will not only set quicker; the high rate of evaporation can cause early-age shrinkage and cracking before concrete sets. Thermal cracking can occur from rapid temperature changes such as those from a hot day to a cool night.

4 Key Temperatures to Check

  1. Air or Ambient Temperature
  2. Concrete Substrate Temperature
  3. Materials Temperature
  4. Water Temperature

Knowing these temperatures and employing the installation guidelines described below will help ensure the desired results are achieved.

10 Installation Guidelines for Hot Weather Concreting

  1. Store materials in a cool, dry place, rather than on-site underneath a tarp, which can get very warm.
  2. Plan the installation early in the day, when both air and substrate temperatures will be at their lowest.
  3. Substrate temperature is most important. Use a surface thermometer to determine the deployment of hot weather concreting procedures. Tenting or shading the installation area can help control substrate temperature.
  4. Work the materials more quickly and in smaller areas. It is critical to use the right tools, including heavy-duty drills for mixing, to maximize efficiency. Providing sufficient labor will minimize the amount of time required to place and finish the materials.
  5. Make modifications to concrete mixtures. Adding retarders, water reducers, extended set-control admixtures, slag cement or synthetic fibers can reduce slump loss, setting time and plastic shrinkage cracking.
  6. For exterior applications, erect temporary wind breaks to prevent rapid evaporation due to air movement over the surface. Use sunscreens, mist fogging or evaporation retardants.
  7. Chill mix water and store aggregate in a cool, dry place. Blocks or bags of ice in a 55-gallon drum of water will chill the water to increase working time. In the case of a pump installation of a self-leveling material, sections of copper tubing or coiled garden hose packed in a drum of ice will chill the water on its way to the pump, also allowing for a longer working time.
  8. The mixing bucket or barrel must be cleaned before mixing a fresh batch of material. Leftover material on the sides of the mixing bucket or barrel can accelerate the set times of the materials.
  9. Consider using accelerators to expedite finishing operations and avoid plastic shrinkage cracking.
  10. Where possible, halt concrete work until the temperature is more conducive to a successful installation.

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

Spartacote Applicator Inter Tech Offers Texas Motor Speedway High Performance Flooring Built to Last

The Texas Motor Speedway.

There’s a reason they call it the Great American Speedway.
Fastest mile and a half NASCAR track.
24-degree banks on the turns.
1500 acres for you and 190,000 of your closest friends.
Four Cowboy Stadiums fit inside the infield.
Home of Big Hoss TV – the world’s biggest high-def video board.

Everything about the place says “high performance.”

And just in time for NASCAR’s Triple-A Texas 500 Tripleheader Weekend, Texas Motor Speedway partnered with Austin-based Inter Tech Flooring, Laticrete Supercap and SPARTACOTE concrete coatings to bring a whole new, high-performance floor to the garage areas and technical inspection bays.

Inter Tech Flooring’s crew applied SPARTACOTE Resinous Coatings and moisture mitigation to give Texas Speedway participants over 22,000 square feet of Texas pride right inside the commercial garage bays.

It’s the commercial bay garage first floor of its kind at any NASCAR track. Beautiful. Tough. Durable. Professional-grade. Ready for action.

They’ve got a saying out there – No Limits. And with LATICRETE and SPARTACOTE, there’s no limit to flooring design possibilities, nor to what you can accomplish.

With over 40 high-performance cars being worked on, this vast, NASCAR garage will be chock-full of power tools, floor jacks, hot tires and hotter torches that leave abrasive dirt and debris everywhere. Add to that – grinders, solvents, engine fluids and cleaners, and your concrete floor better be ready for some serious punishment.

SPARTACOTE concrete coatings offer commercial-grade garage areas customizable colors and textures, excellent protection against abrasion and chemicals, and fast return to service. This concrete coating system is up to the NASCAR challenge. No Limits.

SPARTACOTE coatings also offer flexibility in line striping for safety areas. Designers required black and yellow zebra stripes for the NASCAR inspection bays, deep cherry red SPARTACOTE metallic coatings in the walkways, and over 90 feet of Texas-size Speedway logos embedded in those cherry-red spaces.

This floor design needs exacting measurements and precision equipment to make sure every line and stripe ends up straight and even.

On the walkways, a base coat of SPARTACOTE black goes down first over the concrete to guarantee an extra-rich, deep cherry metallic top coat.

The stripe design in the NASCAR inspection bay starts with the same solid black Spartacote base coat. A rich yellow mid-coat covers the black base. The end result captivates—right through the door and into the hall.

And to lock-in every stripe, sparkle and letter in place, the SPARTACOTE resinous flooring system is finished with a clear top coat, giving it a spectacular, rock-hard, slip-resistant finish that’s ready for anything the world’s top race car drivers and mechanics can throw at it.

Inter Tech Flooring, LATICRETE SuperCap and SPARTACOTE concrete coatings systems: teaming up to give you the “Official Garage Flooring System of Texas Motor Speedway.”
