Ameripolish® PCA – Drastically Reduces Crazing and More

This Penetrating Curing Agent is an impressive alternative to traditional cure and seal products.

Ameripolish PCA (Penetrating Curing Agent) chemically hardens and dust-proofs concrete for improved abrasion resistance without forming a coating. Recommended for new concrete pours, PCA adds initial water and stain repellency while retaining slab moisture for improved curing. PCA requires no UV light for dissipation and can be used with integrally colored concrete.

 

Penetrating Curing Agent Strengthens at Cure

  • Improves cure by retaining slab moisture
  • Drastically reduces crazing and map cracking
  • Highly penetrating, non-film forming – no need to grind or chemically remove layer to seal and burnish
  • Forms a hydrophobic barrier and increases stain repellency
  • Greatly improves abrasion resistance
  • Helps reduce efflorescence and minimizes dust for healthier indoor air quality
  • Replaces traditional cure and seal products on new concrete

Top 3 Reasons Traditional Cure and Seal Products Fail

  1. Crazing (map cracking) – due to early surface drying and slab shrinkage
  2. Scuffing – doesn’t penetrate and protect within the slab
  3. Yellowing – doesn’t have the stability to protect against UV light

How is PCA different from other curing agents? Older generation cure and seal products form a membrane at the surface of concrete to retain moisture for curing, which can result in a variety of flooring challenges:

  • Soft, porous surface leads to pitting, crazing and map cracking
  • Very low abrasion resistance shows forklifts or tire marks, scuffing and overall wear deterioration
  • Discoloration or “yellowing” of floor surface

In addition, topical cure and seals must be mechanically or chemically removed before grinding and/or polishing the new flooring surface. PCA actually soaks into the surface, leaving no topical residue.

How well does PCA work as a curing agent? PCA delivers proven results. A study by American Engineering Testing, Inc. performed on fresh concrete compares a non-treated control slab versus one treated with Ameripolish PCA. While the control slab is only able to retain 70% of its moisture in a 72-hour period, the surface using PCA keeps 93.6% in the same time-frame. Other findings:

  • PCA eliminated any crazing experienced by the control slab when subjected to high temperature and rapid air movement
  • PCA improves abrasion resistance
  • PCA retains 23.6% more moisture overall
  • PCA is an effective curing agent and finishing aid

Expanded Benefits of Ameripolish PCA

Other curing agents only retard moisture loss to varying degrees. In addition to moisture retention, PCA actually strengthens the concrete surface by improving abrasion resistance.

  • PCA has also been shown to be very effective at reducing surface defects, including crazing
  • PCA coverage rate is dramatically higher: 1,000 – 1,500 ft.2 per gallon, when applying product with microfiber mop
  • PCA has a lower than average cost per square foot than leading competitors
  • PCA is the best solution when grinding and polishing
  • PCA is the best solution when doing a seal and burnish application
  • PCA is better than traditional cure and seal products, regardless of the application

Harsh chemical strippers or aggressive metal bond abrasives are no longer needed to remove PCA – like traditional topical curing products.

What are the cost-benefits of using PCA as a curing agent? True film-forming curing agents always require removal prior to preparing the concrete further. Many dissipative cures may also require removal due to certain environmental requirements, such as UV exposure, to degrade the material. PCA does not need removal, saving labor and material costs.

Densifier Comparison Guide

3 Popular Concrete Densifiers Demystified

Concrete densifiers are also known as chemical hardeners. When applied to a concrete floor, a densifier fills empty spaces in the material and oftentimes forms a chemical bond with the concrete, changing its properties and increasing surface density.

Benefits of Using Densifiers

Densifiers are used specifically to improve the concrete surface when polishing. As long as free lime is present, the complete saturation of a densifier will make substrate harder, which allows a more aesthetically pleasing finish grinding and polishing, and prolongs the durability of the polish. Other benefits include:

  • Reduced dusting
  • Higher, deeper gloss than untreated concrete
  • Increased abrasion resistance and weathering
  • Longer floor lifespan
  • Locks in a topical color application
  • Stain resistance
  • Easier to clean

Types of Densifiers

Different types of densifiers create a chemical bond with concrete in a variety of ways. Runyon Surface Prep carries a wide selection of densifiers; below is a comparison of the three most popular.

Ameripolish – 3D Hybrid Silicate Densifier

  • Developed to help keep concrete looking newer longer
  • Improves performance of new, old or aged and existing concrete
  • Can be used with integrally-colored cements
  • Contains UV stabilizers to help protect color from fading
  • Penetrates fast for a deep seal
  • Hardens deep to improve durability even after grinding

Convergent Pentra-Sil Densifier

  • Developed to increase the integrity and life of concrete floors
  • Patented nano lithium hardener technology reacts with the concrete to produce calcium silicate hydrate (CSH), creating a strong, virtually impenetrable and durable finish with only one-coat and no rinsing
  • Resistant to bacteria

Prosoco Consolideck LS

  • Developed to improve the appearance and performance of architectural masonry
  • Gives new life to historic buildings, monuments, existing buildings, new masonry and reinforced concrete structures

5 Simple Steps to Keep Concrete Dyes from Fading

How to Keep Concrete Dye from Fading

Concrete dyes are an attractive way to add color to a concrete floor. However, because of the nature of dye — it penetrates the porous surface to create color, rather than reacting chemically with the concrete — contractors can conduct a few assessments and tests at the job site before determining whether a concrete dye is the right product for the job:

  1. Type of Concrete. Typically, a pure color dye will change slightly, due to the minerals in the concrete, taking on a lighter or darker shade, which can also change with time. Adjust the dye color to the type of concrete for the desired shade.
  1. UV Light Stability. Sunlight can damage dyed concrete floors, causing vibrant colors to fade. Check if windows in the room are made with glass containing UV-protection, which can keep floor color from fading.
  1. Moisture Vapor Test. When moisture in concrete brings salts to the surface, it causes dyes to seep deeper into the floor, diluting their color. Testing for efflorescence cannot only root out a bigger moisture issue, it indicates whether water will cause the color to diminish.
  1. Use Stain. Concrete stains work differently than dyes, reacting chemically with the concrete to create color that is more resistant to fading from sunlight or moisture.
  1. Apply Guard. A proper guard provides long-lasting, breathable protection for the floor and its color. Apply after polishing. 

Fixing Faded Floors

If the concrete floor is already fading:

  • Clean and seal the flooring surface to stop additional fading
  • Remove the sealer, then re-dye the floor and protect with sealer

When you’re looking for quality concrete dyes and sealers, count on Runyon Surface Prep. We carry two of the top-rated concrete dyes and sealant brands in the business. AmeriPolish products assure perfect color that resists fading through cleanings, scrubbings and traffic.

Applied Flooring’s Polished and Colored Concrete Success in Troy, MI

Last week one of our customers, Applied Flooring, had a job in Troy, MI at a Nordstrom store. Along with the Applied crew, the Nordstrom GC and technicians from CTS Rapid Set and Metzger/McGuire helped complete this floor. Below are the before pictures, showing the extensive structural damage. Because of so many cracks breaking up the surface, the crew wasn’t able to polish first thing. Instead, the first step was filling the cracks. Then, once the concrete floor was repaired, an overlay was applied, the control joints were cleaned and recut and the concrete was colored. Below you can see the process from initial pour to finished look.


Concrete Overlay and Color Application

Applied Flooring used CTS Rapid Set’s TRU self-leveling overlay on the floor, and colored it with AmeriPolish OS dye. The crew worked in 20-degree weather and wrangled both the water and pump hoses from outside in the parking lot up a flight of stairs to the work area. The 300′ water hose and 400′ pump hose were at their maximum lengths. Applied made it work though, and after the overlay was laid they moved into the color application stage.

One of the biggest takeaways from this particular job revolved around the importance of color intensity. Initially, OS integral color was used, but the pigment wasn’t strong enough, so the dye was applied after the fact to accommodate the time-sensitive nature of this project and to best utilize resources.

Below you can see the floor after the second pour of TRU, the floor after 3DHS densifier was applied and finally, the polishing stage.


The Finished Look

Although there were a few unexpected surprises throughout this process, as is common with any job, Nordstrom was incredibly satisfied with the final polished floor. You can see below how reflective and high-end this space appears, especially after the merchandise was moved back in.

Truly Elegant Decorative Concrete Designs Liven Up A Space

The decorative concrete industry is constantly innovating and pushing out new, creative designs, for both residential and commercial flooring. A colorful, patterned concrete surface not only creates a lasting impression, but it can set the tone in a space. This is the case for a recent job completed by Elegant Concrete Polishing in an elementary school in Connecticut. The bright colors and swirling shapes and curves evoke an energetic vibe throughout, as you can see in the images below.


Connecticut Elementary School Project

The pictures above are of the 17,000 square foot elementary school. The Elegant Concrete crew installed the polished concrete flooring using the AmeriPolish SureLock System. The slab was ground and polished from a 40 grit metal all the way up to a 1500 grit resin. The decorative flooring design was installed per the architectural layout, established with another firm that Elegant has built a solid relationship with. In order to accomplish such a colorful finished product, Elegant used 6 different colors from AmeriPolish in the initial overlay stage. Colors include: Patriot Blue, Turquoise, Forest Green, Green, Burnt Sienna and Sepia. After polishing the floors completely, Elegant protected them with SureLock Densifier and sealed them with SureLock Stain Shield.

Elementary School Concrete EdgesUsing Terrazzo to Create a Border

In another project Elegant completed recently, the crew installed CTS RapidSet TRU self-leveling overlay and then used a zinc terrazzo bar around the perimeter to act as a divider for the border. Elegant ground and polished the TRU after it was entirely laid and set. Then finally, the crew dyed the perimeter band with AmeriPolish OS Dye in Terra Cotta to give it a two-tone effect and clearly establish the border from the main center area. In the picture to the right you can see how crisp and polished (so-to-say) the terrazzo strips are in conjunction with the polished concrete. Although a slightly more expensive material to use on a slab, the result is unparalleled.
