Stripping and Waxing Terrazzo Floors vs. Stripping and Polishing Terrazzo Floors- The REAL Green Solution by Rhino Proflooring

Stripping and Waxing a large Terrazzo floor area in a commercial setting is an expensive and reoccurring endeavor. When someone considers the cost of waxing a terrazzo floor area two to four times per year with materials and manpower included, the cost comparison to be made in comparing this process versus stripping and polishing a terrazzo floor can often reap a company noticeable benefits. Although stripping and polishing a floor one time is more costly than stripping and waxing a floor twice per year, the overall costs, wear and tear, and appearance unequivocally states that polishing can be a better solution in most situations. The average commercial terrazzo floor area requires stripping and waxing applications at least four times per year, dependent primarily upon its overall use. An average polished commercial terrazzo floor area requires one extraneous polishing effort with routine maintenance that local janitorial staff can conduct with no special training.

In so far as stripping the finish off the terrazzo floor area is concerned, the process remains the same. The floor finish is stripped off with a stripping compound. The floor is chemically neutralized, rinsed twice, and left to dry. After the area is dried thoroughly, new wax coats are applied layer upon layer, as each previous layer dries, a new layer is applied until a satisfactory finish is attained.
On the polishing end, the terrazzo floor area is stripped in the same manner the floor was done, when it was waxed. However, once the neutralization and rinsing process has been completed grinding stones are used with a Planetary Floor Grinder are used with an auto scrubber so as to hone "grind" the floor surface to a semi rough texture. Then,series of progressively finer diamonds are used to restore or buff the shine back to the floor surface. Some call this vitrification.  By using this process your Terrazzo looks like a granite counter top From an appearance state, the buffed and restored surface resulting from the polishing effort actually presents itself in a much better state than a waxed terrazzo floor, very reflective and elegant in its natural state.
The pros resulting from polishing are that a company can reduce its overall floor care costs and minimize the floor "down time". General maintenance via daily dust mopping and a weekly autoscrub with water is all that is needed verses two to four times per year of waxing and striping. From a cost stand point, you remove the cost of all the wax and stripper chemicals and in so far as manpower is concerned, your custodial/maintenance staff can concern itself less with floor care projects and more with other cleaning projects. For the environmentalist in us, the use of less chemicals in the cleaning process is a sell to everyone, because less chemicals are used in restoring our floor areas to life.

From the overall cleaning perspective, the look is sheen, classy, and elegant. The price is affordable (currently) and it offers a good alternative to the use of nauseating cleaning chemical compounds in the workplace. Natural stone or terrazzo regains its appeal as a natural composite material, which is why it is often selected in the commercial setting, for its intrinsic feature value. The floor will actually regain its shine and appeal and gain the "eye" of a company's patrons, because most people notice floors first when entering a building. The reason they notice your floors first is simple, most people walk forward facing downward; therefore, most people notice your clean/dirty floors first when they enter your building.

The Death of Epoxy Flooring- It's Really That Bad

Failed Epoxy Floor
Polyaspartic technology is the only technology we use for our customer’s decorative coating needs. Epoxy coatings are simply outdated.  That begs the question; Why do so many installers continue to use a substandard products?  You guessed it...It saves THEM money! Why would you used a product tht's not UV stable, has less abraision wear resistance,has less elongation, is prone to hot tire peel, and is not mechanically bonded to the substrate?  I have done the research on my competitors "Systems" which somehow promise and lead you to beleive that "Thicker is better"...of course failing to mention that thicker costs more and leaves more on your floor to fail. In addition an Epoxy base coat with a urethane top coat, or even a polyaspartic top coat, fails to meet the proper mechanical bond required for a high performance floor coating. Folks don't beleve the hype or trip into the pitfalls of fancy systems, special processes, and fancy names.  When mixed together and applied to concrete polyaspartic forms today’s most durable, weather resistant technology – for concrete in, firehouses and EMS buildings, garage flooring, commercial, industrial flooring, retail storefront flooring and customer service areas.
As you can see from the schematic the deep penetrating seal of the base coat is crucial to the mechanical bond achieved by polyaspartics. Epoxy simply fails to achive that bond and in addition is not UV stable, is not as elastic as polyaspartics, has less abraision wear resistance, is prone to hot tire picks up and sometimes requires DAYS more to dry.

Polyaspartic is clear, but can also be tinted with color pigment, added chip, or quartz media for a decorative finish. The formula originally developed by Bayer ™ material sciences was used for painting or coating steel and concrete and was used on bridges, tanker ships, off shore oil rigs, and other heavy commercial uses to prevent corrosion from salt water, weather and harsh chemicals.
The outstanding performance and long-life durability led to research and development of today’s formulation used on concrete surfaces.
In 2006, pioneers in the polyaspartic industry found that when concrete was prepared properly the base coat would wet and absorb into the surface like water into a sponge. (100% Epoxy CAN NOT do that) The mid coat then fills the capillaries or pores and combines with the surface of the concrete floor; permanently bonding the concrete to the coating system.
This results in no delamination failures; unlike epoxy coatings that adhere on top of the surface like Velcro and can, and will delaminate resulting in a failed floor. Polyspartic, if blended properly, will tolerate, with no negative reaction, two conditions that always exist in concrete, moisture and alkalinity.
At the point of contact to the surface, moisture is a bond-breaker and alkalinity, over time, will delaminate and fail your decorative coated floor. This technology has solved a three-decade old challenge of coating failure. In the past years, three factors of success have come to the forefront in the coatings industry – preparation, experience, and training of the applicator/contractor. These factors will determine the success, and longevity of your coating project. Contact us today for a free Estimate on the last floor you'll ever need.  (910) 574-5547  john@rhinoproflooring.com

Acid Stains...Everything You Wanted to Know

Acid Stains are not a paint or coating or a sealer. Acid Stained Concrete is a coloring process involving a chemical reaction on a cementitious material. A solution made with water, acid and inorganic salts reacts with minerals already present in the concrete (All concrete has calcium hydroxide as a biproduct. This is slaked limed.

This picks up carbon dioxide from the air and becomes calcium bicarbonate. This is effluorescence. These are the chemicals that the stain reacts with). Acid stains are made from hydrochloric acid, wetting agents and metallic ions. When this solution is placed on concrete it colors the concrete by chemically combining the metallic ions with the particles in the concrete to form oxides; the result of this reaction is color. Chemical stains can be applied to new or old, plain or colored concrete surfaces. Although they are often called acid stains, acid is not the ingredient that colors the concrete. Metallic salts in an acidic, water-based solution react with hydrated lime (calcium hydroxide) in hardened concrete to yield insoluble, colored compounds that become a permanent part of the concrete. There are many manufactures of Acid Stain and most produce stain in 8 colors that are variations of three basic color groups: black, brown, and blue-green.
Acid Stains give concrete a mottled, variegated, marble-like look. Never expect Acid Stain to be uniform or have an even tone, you will get different reactions from slab to slab, and even on the same job you may see different coloration patterns. Variations of colors and mottling are to be expected and enjoyed. It is the random mix of tones and shades that gives an acid stained floor it's unique beauty.
Some stain manufactures will use adjectives such as Vintage or Antique to describe their version.

How Stain Works

Acid stains are made from hydrochloric acid, wetting agents and metallic ions. When this solution is placed on concrete it colors the concrete by chemically combining the metallic ions with the particles in the concrete to form oxides. The finish won't fade or chip,it is permanent. The acid in chemical stains opens the top surface of the concrete (this may be referred to as "etched"), allowing metallic salts in the mixture to reach the free lime in the concrete. Water from the stain solution then fuels the reaction between the Lime and the Metalic Salts. Stains will normally be applied to a surface for 4 or more hours. However, the surface will continue to develop its patina - an appearance of something grown beautiful especially with age or use; established character for several more hours.
Other factors that affect the outcome include:
• Cement properties and Mix Design
• Admixtures used
• Type of aggregate used
• Concrete finishing methods
• Concrete age and moisture content when stain is applied
• Weather conditions when stain is applied
• Efflorescence
In general, cements that produce larger amounts of calcium hydroxide during hydration will show more stain color, and higher cement contents produce more intense colors. If they are near the surface, calcium-based aggregates, such as lime-stone, take stain readily and deepen the color of the concrete above them. Solid aggregates, such as gravel, don’t react with the stain.
Acid stains, unlike paints, are not opaque - they are translucent. Some areas will be darker than others, similar to marble or flagstone. Along with the naturally occurring variegations and marbling - any blemishes and imperfections in your concrete simply add character and charm. Even cracks can add to the look.

Don't be Fooled!

A major home improvement store offers a 2-coat "Premium Floor Coating" at $2.25per square foot, however, they include the thickness of the flakes as part of their overall finished thickness. They also have a square foot minimum of 500 sq ft. This means that their "Premium Package" is actually 8-12 mils and for a 2 car garage thats $1125.00 and less than half the thickness of our floors and it is not turn key. This same Home Improvement Company charges extra for crack repair and non-skid additiv and by the time you add those into the price your paying the same thing as you are with us except your getting twice the thickness, durability and product. The flakes included at the home improvement store are added to the top coat and are therefore left exposed, rather than encapsulated, so that the overall durability of your coating is then only as strong as the flakes themselves. Trust us, you dont want that.

Why should I bother to put anything on my concrete surface if I am happy with the natural appearance of it?

While concrete is a very durable product it does deteriorate over time. As you can see from this photo over time your concrete will begin to fail. Now, your probably thinking this is an extreme case and that your concrete wouldn't experience as much traffic and therefore it wouldn't show signs of wear but take note of homes where concrete patios are exposed to the downspout off the roof.. This area almost always reveals a place where the underlying aggregate is exposed. Naturally it is more common on an older home because this is a process that tears down your concrete slowly and you might not notices it as easily on a newer home...but the same principal applies whether it is a residential patio, a department store loading dock or your concrete driveway or garage, the best way to assure yourself of years of aesthetically pleasing and structurally sound surfaces is to protect those surfaces. With all that in mind, do not be fooled into thinking that because your home is new you will not have a problem, inspect your exterior surfaces for signs of deterioration and if you see rough spots or exposed aggregate then a coating might be right for you. Coat your concrete, it is not only a beautiful thing to do, it is a smart thing to do.

Whats the best way to clean my new Rhino Fast Floor Floor?

We recommend a simple broom and bucket with a non-abrasive, gentle cleaner like amonia.  A prime cleaning agent would be a citrus based cleanser/degreaser. A very small amount is needed just a few capfils in a 5 gallon bucket. Never use harsh chemicals or bleach. They wont hurt your floor but they are "surfactants" wich will leave a film on your floor. Your new Rhino Fast Floor is resistant to stains and for that reason will be much easier to clean than your tradition floor coverings so a simple broom and squeegee should be perfect for most conditions.  For high traffic and industrial areas it is perfectly acceptable to hose it down or pressure wash it. Although all of our coatings are chemical resistant, it is not necessary, nor is it recommended to routinely clean your floor with harsh chemical cleansers. As a general rule a broom and squeegee is all you will need in most circumstances. Be sure to ask us for a Cleaning sheet when you purchase one of our floors.
