Protecting Polished Concrete Floors with Sealers

Protecting Polished Concrete Floors with SealersStain protectors, guards and sealers are vital for ongoing polished concrete floor maintenance.

The final step in the concrete polishing process involves the application of a stain
protector. Stain protection is vital to the long term aesthetics of polished concrete, providing protection from discoloring penetrating stains and chemical etches. There are three main categories of stain protectors for polished concrete; penetrating, semi-penetrating guards and topical sealers. Each has its own features and benefits and its own required upkeep schedule.

3 Types of Polished Concrete Sealers

  1. Penetrating sealers: Made from a variety of silicones (silane, siloxane, silicate and siliconate) that penetrate deep into the surface. By sealing the access channels into the interior of the concrete, they shield against infiltration of liquids. Because they allow the concrete to breathe, these products are a good option for outdoor surfaces. Ideal for industrial facilities that want to avoid frequent applications, they provide invisible protection to the flooring. Since these sealers are not a topical layer, they do not alter the surface appearance by creating additional gloss or sheen and they also are not subject to being abraded away by foot traffic. However, they can breakdown over time and will need reapplication periodically. Use a sprayer and microfiber to apply this type of sealer.
  2. Semi-penetrating sealers: Often known as guard products, these have a topical aspect that will increase a floor’s surface sheen while also providing stain resistance and repelling water. Ideal for both indoor and outdoor concrete, these sealers (applied with a sprayer and microfiber) wear faster than polyurethanes and epoxies and need to be re-applied depending on the amount of foot traffic.
  3. Topical sealers: Give the concrete a high glossy shine while forming a protective film on the surface, like polyurethane and epoxy. They are economical and easy to apply by spray or roller. These sealants repel water and provide a durable chemical and abrasive resistant surface. Ideal for retail spaces where the vibrant color and high sheen of the flooring is an essential part of the design. They need to be re-applied periodically due to traffic wear and some may yellow due to UV exposure. Regular maintenance to prevent stains and scuffs is required to keep the surface looking its best.

Regular Maintenance

The type of sealer you select determines the frequency and extent of routine maintenance. For industrial floors, penetrating stain protectors offer better protection and liquid repellency than topical sealers. Because they are not a coating like topical products, stains and spills need to be removed promptly to prevent damage. Diamond impregnated pads can be used to mechanically clean and maintain floors. They come in a variety of grits for a variety of needs.

Use Diamond Pads to:

  • enhance the natural gloss and shine
  • deep scrub or strip a floor before recoating
  • repair damage from stains and etching
  • apply a light honing
  • prepare a floor for sealer application

Burnishing

If you over-apply a sealer and need to remove a leftover haze or film, you can burnish with a high grit polishing pad to enhance gloss after reapplying the sealer or guard. Use a diamond impregnated pad in conjunction with a burnisher to eliminate the excess.

Restoring Polished Concrete After Spills & Stains

Restoring Polished Concrete After Spills & Stains

Polished concrete is a fantastic flooring choice for industrial facilities, commercial spaces and retail stores. Though durable and low-maintenance, it is possible to damage this type of flooring. Liquids left on a polished surface can stain or etch, especially if it is citric, acidic or caustic in nature. Stain protectors are added as a final layer to prevent damage.

Removing Scratches and Stains

If an etch happens, use diamond impregnated pads and specially formulated cleaners to restore the concrete. The condition of the floor determines which grit to start at to remove scratches and stains. Always start with the least aggressive grit that will effectively remediate the etch. They can lighten a surface and remove dyes.

Polished concrete cleaners are formulated to remove dirt without damaging the
refinement or aesthetic values of the floor. They work with stain protectors to retain color and prevent further damage. The source of a spill will determine how to clean it. We compiled a list of substances that can stain when spilled and the appropriate way to clean them.

  • Acidic Substances (e.g. cola, milk, pickles, mustard): Acids will etch if not removed quickly. Clean immediately with fresh water or a concrete cleaner like Prosoco DailyKlean.
  • Adhesives: Remove the tape with a razor blade, being careful not to scratch the floor surface. Use Prosoco Wax & Cure Remover or acetone to eliminate the gummy residue.
  • Alkaline Substances (e.g. laundry soap, ammonia): Clean spills quickly and minimize stains by using a concrete cleaner like Prosoco DailyKlean. Refresh the gloss with a stain guard such as Prosoco LSGuard.
  • Candy: Remove the substance from the floor and clean any sticky residue with a concrete cleaner. Prosoco DailyKlean works well for this.
  • Chocolate: To get rid of most stains, dilute Prosoco Cleaner/Degreaser in a 1:10 ratio and light scrub.
  • De-Icing Salts: Use a concrete cleaner like Prosoco DailyKlean to remove the deposits.
  • Grease, Oil, Brake Fluid: Following a spill, clean with Prosoco Cleaner/Degreaser diluted to a 1:10 ratio with water.
  • Set-in Stains: Use Prosoco Oil & Grease Stain Remover to pull out tough stains. For deep stains, you may need to apply more than once.
  • Gum: Remove quickly to avoid staining and gently scrape up the remains. Eliminate leftover residue with Prosoco Wax & Cure Remover.
  • Heel Marks: Rub scuff marks with a concrete cleaner like Prosoco DailyKlean.
  • Mildew – For biological staining, treat the area with Prosoco EnviroKlean ReVive.
  • Tire Marks – Scrub smudges with Prosoco Cleaner/Degreaser.
  • Water Spots – Use of a high-speed rotary burnishing machine gets rid of most water spots quickly. On stubborn spots, dilute Prosoco LSGuard in a 1:10 ratio with water and lightly mist the surface before burnishing. The product creates a wet-looking shine.

The Benefits of Polished Concrete & How to Maintain It

The Benefits of Polished Concrete & How to Maintain It

Polished concrete is a cost-effective alternative to traditional flooring. Ideal for use in industrial and commercial spaces, polished concrete is most often used in large warehouses, retail stores, office buildings or private residences. By treating an existing concrete subfloor with a multi-step polishing process, no other materials are needed.

The Benefits of Polished Concrete

  • Ecologically Efficient: installation requires no other flooring materials
  • Cost Effective: it has a long life span
  • Environmentally-Friendly: it releases no toxic fumes or VOCs
  • Easy-to-Maintain: low up-keep
  • Durable: it does not rip or scuff – can withstand heavy foot traffic
  • Allergen-Free: does not harbor dust mites, pet dander or mold
  • Versatile: it comes in a variety of colors, finishes and sheens
  • Reflectivity: the high-shine cuts down on the need for artificial lighting

The Polished Concrete Process

Thorough prepping of the concrete beforehand, to remove stains and moisture, helps to achieve quality results. The grinding stage removes imperfections and flattens the concrete surface by refining with a progressive sequence of diamond tooling, starting with lower grit metal bond tools (e.g. 30s then 70s), hybrid coppers and finally with resins. Depending on the porosity of the concrete, densify after 200 or 400 grit to harden the floor. Then continue on with resins to polish the floor up to whatever level of shine your job requires (e.g. 400, 800, 1500). As a best practice: protect the floor with a topical guard or penetrating stain resistor. Guards/sealers are preferable for retail or commercial floors that require an aesthetic appearance. However, keep in mind that they are topical, so will scratch, scuff and walk off over time depending on level of foot traffic. Penetrating stain resistors help to tighten up the floor at a sub-surface level, protecting against spills, water, etc. These are ideal for industrial floors or floors that don’t require as shiny of an appearance, but need the stain resistance.

Properly Maintaining a Polished Concrete Floor

Although polished concrete flooring is relatively low-maintenance, it is not maintenance-free. Polished concrete typically does not require frequent sealing. Abrasive dirt and grime can result in the top coat sealant, wearing down and losing its luster. As a result, proper cleaning is needed to keep the high gloss shine from dulling.

  • Dust Mop Daily: this will remove dirt and grime accumulation
  • Frequent Wet Mopping: use water with an appropriate cleaner – avoid harsh chemicals that can break down the sealant
  • Use a pH Neutral Cleaner: solvents with too much acidity or alkalinity can dissolve the concrete and dull the shine
  • Work in Small Sections: keep the cleaner from drying and leaving a haze by tackling small sections
  • Correct Floor Pads: use softer (higher grit) cleaning pads to prevent scratching and etching e.g. white pads
  • Automatic Floor Scrubber: use non-abrasive attachments to clean large areas i.e. soft brushes, not coarse black brushes
  • Wipe Up Spills: prevent stains by cleaning them up immediately

RSP Q8 Series – Quality Diamond Tooling for Superior Concrete Polishing

Runyon Surface Prep’s Q8 Series of wet/dry diamond tooling offers high-quality compositions and a variety of grit/bond distinctions to complete any polishing job.

Today’s contractors have a wide variety of concrete flooring styles and finish options from which to choose. Successfully prepping and polishing concrete begins with selecting the right grit and type of diamond tool to use. To narrow down your options, know the hardness of the concrete (hard, medium or soft) and the desired finish you wish to achieve for your customer.

Know Your Concrete’s Hardness

One of the most frequently used terms in diamond tooling is bond. It refers to the matrix that suspends the diamonds. The type of concrete hardness determines whether you will need a hard bond tool (for soft concrete) or a soft bond tool (for hard concrete). Using the incorrect diamond tool can slow down productivity and incur additional cost for replacement tools. We’ve simplified our Q8 metal bond tools with an easy identification delineation:

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!
