Step-by-Step Overview for Acid Stained Concrete Floors in New Orleans


Stained Concrete Floors

Stained Concrete Floors

Stained concrete floors are a low-maintenance alternative to other types of flooring, such as carpets and hardwood floors. A concrete floor is more durable than other types of flooring since it doesn’t easily scratch and can handle heavy equipment. Maintenance needed to keep the floor polished is minimal, and the designs are versatile and can accommodate different kinds of stains, depending on the taste of the home or business owner. In New Orleans, acid stained concrete can be a good functional and decorative option for those who want a sustainable yet stylish floor.

Checking Concrete Compatibility

Before acid staining, we make sure the concrete floor is in good condition for the type of stain to be applied. Floors that have been waterproofed will be resistant to the stain and reaction cannot occur, so checking the floor before attempting to do acid staining is crucial. The water test should be sufficient to know if a surface has been treated with waterproofing agents. Simply pour some water on the surface, and if the liquid is not absorbed and beads form, then the concrete has most likely been treated with waterproofing agents.

Preparing the Surface

Once we’ve checked that the floor can be stained with an acid base, then proper preparation begins. When using acid stains on concrete, such as Sundek’s SunStain SunAcid Reactive Stain, power-washing the area to be stained is the primary step to remove dirt and all possible contaminants that the concrete has on its surface. The area must be allowed to dry out completely afterward until there is no sign of water or moisture left.

Staining the Concrete

Application of Sundek’s SunAcid comes next, and the reaction is given at least two hours to settle. After the concrete is allowed to react with the acid, the stain has to be neutralized. A neutralizing solution, usually part water and part ammonia, is applied to the surface, washing away the stain residue. Fully neutralizing an area may take more than one scrubbing to take away the residue, especially if a darker stain color was applied and if the stain was left on for a longer period.


Once the stain has been neutralized and the floor is ready for finishing, a proper sealer should be applied. To enhance protection of the newly stained floor, Sundek’s Crystal Clear solvent base sealer can be used. It is also used to improve the appearance of the acid stained floor and make sure that the stain stays on.

Do’s and Don’ts for Stained Concrete in New Orleans

Stained concrete in New Orleans is a hot trend that allows you to express your personality and enhance the aesthetics and value of your home. Without question, stained concrete is in a league of its own.

Stained Concrete Do’s

Concrete staining is not the right solution for every person or situation. Therefore, you need to have a professional contractor look at your project to determine if this is, in fact, the best option.

For stunning results with stained concrete in New Orleans, you want to hire an expert with specialized knowledge and skill who relies on quality products, such as those offered by Sundek:

  • SunAcid – Reactive acid stain that mirrors nature’s own beautiful colors.
  • SunH20 – Water-based stain that can be combined and layered for a customized finish.
  • SunDye – Liquid concrete dye that is easier to apply, dries faster, and comes in vibrant color options.

To transform an old or existing floor using stained concrete, your New Orleans contractor must grind down the slab deep enough to remove the curing compounds.

For enhanced durability, a quality sealer is imperative. Unfortunately, low solid sealers and cures/seals do not provide enough protection for acid-stained concrete, so multiple coats of urethane are recommended.

Stained Concrete Don’ts

Concrete staining is not a good do-it-yourself project. To correct a mistake, you cannot simply add more acid. Because free lime in the top surface is eliminated, the floor has to be ground down to expose fresh concrete. Curing and sealing are other “don’ts.” Typically, wet concrete is cured, but compounds for both curing and sealing do not work well with acid stains.


The bottom line is that for decorative  concrete that exceeds your expectations, you should hire a professional contractor from Sundek of New Orleans.

New Orleans is a city of love, culture, history, and color. Thanks to Sundek’s incredible products coupled with the skill of professional contractors, you can choose amazing outdoor concrete colors to enhance your exterior living space.

Whether you are designing a backyard kitchen/entertainment area; updating an old pool deck; or changing the aesthetics of a walkway, pathway, or patio, you have multiple color options for your concrete.

Stunning Color Options

Among the many wonderful outdoor concrete colors in New Orleans, five in particular stand out.

  • Gray – Although concrete is gray in its natural state, using different techniques takes things to an entirely new level. Gray is trendy, industrial, and ultra-modern, so if you prefer this look, your contractor can use color hardeners or integral pigments to develop the exact shade of gray you want.
  • Tan – This color is warm and inviting. Remember, your color choices on the product used. For instance, with the SunDye exterior product, you can choose between Malay Tan and Desert Tan. To create this earthy hue, stain, color hardener, or integral pigments are used.
  • Amber – The color amber is fun and welcoming with distinct Mediterranean flair. While amber concrete would be stunning for any home, it definitely enhances homes with clay roof tiles and those with a Spanish-style exterior. To create different hues, integral pigments, color hardeners, and stains can be used.
  • Brown – Brown is another great choice for outdoor concrete in New Orleans. In addition to looking rich and sophisticated, brown concrete does not show dirt and muddy footprints. For this color, color hardeners and stains, like Sundek’s SunH20, work best.
  • Red – For something vibrant and chic, you can never go wrong with red. Red outdoor concrete can be subdued or ramped up, depending on your personal preference.

A Multitude of Options

Sundek offers a wide range of colors that extend well beyond the five most popular choices. Using various products and techniques, your contractor can create virtually any aesthetic. For example, SunChip is a unique product in which vinyl acrylic paint chips are added. In addition to chips of different sizes, they come in 25 gorgeous colors.

Why Painted Concrete Floors Peel, and Options to Fix the Problem

Painted concrete floors in New Orleans sometimes peel, which is a problem that occurs for a variety of reasons:

  • Inadequate product or coating quality for the type of substrate and amount of wear and exposure
  • Poor adhesion, which is relatively common whenever hardeners are added to concrete
  • Oil, grease, and/or dirt permeation
  • Efflorescence caused by moisture migration and leaching alkali
  • Aged concrete floors
  • Seeping moisture due to no installed barrier
  • Oil-based finished applied to bare, un-etched, and uncured floors

Viable Solutions

No matter the cause of the problem, several viable solutions exist.

  • Moisture – Concrete flooring must be void of moisture. A professional contractor can conduct a moisture or dampness test. If a problem is discovered, it must be eliminated prior to staining the floors.
  • Surface Contamination – The surface of concrete floors must be properly washed. In this case, Sundek offers several different products, each powerful and effective. Sunkleen is strong enough to penetrate greasy soil where the bond is broken at the surface. For decorative textures, Sunspot eliminates all types of oil-based stains, including grease, tar, tire marks, asphalt, and tree sap. Suntouch is an environmentally friendly product as powerful as concentrated Muriatic acid yet safe and ease to use.
  • Adequate Adhesion – To ensure the surface of the concrete has a sufficient profile for strong adhesion, it must be profiled.
  • Surface Preparation – Existing peeled or checked paint on concrete floors in New Orleans must be scraped and removed to create a sound and dull surface. In addition, release agents, salts, laitance, curing compounds, efflorescence, and other foreign matter need to be removed using chemicals or mechanical means. Once the floors are thoroughly swept or vacuumed, they can be coated or stained with a Sundek product, followed by being sealed with SunClear EcoProtect, which is eco-friendly and ideal for everyday protection, or SunClear UltraProtect, an industrial-strength clear coat formulated for high-traffic surfaces.


Which Materials Are Best for Concrete Crack Repair

Depending on the problem, the best repair for cracked concrete might be nothing more than high-quality concrete material. However, to repair cracks for greater durability and bond strength, you want to consider specialty formulated repair materials and also other techniques used by the pros themselves.

Concrete Crack Repair

For example, Sundek dealers spent more than 40 years perfecting the Custom Scoreline Effects technique for controlling the natural expansion and contraction that occurs when concrete heats and cools.  Typically, materials used for camouflaging concrete cracks in New Orleans are polymer-modified concrete, which is basic Portland cement with an aggregate mixture and added polymer. When used with the right technique, this ensures an outstanding result.

For the best repair material for concrete crack repair in New Orleans, several key factors must be considered.

  • The extent of damage is determined prior to choosing the repair material. That way, the contractor knows if the crack can be patched or if bonding is required.
  • How fast does full strength need to be achieved?
  • Will a one-part material suffice or is a more difficult-to-use yet far superior two-part repair material better?
  • Extremely low shrinkage is a critical characteristic of material used for concrete crack repair in New Orleans. If the concrete matrix has already shrunk, any additional shrinkage of the repair material would cause an inadequate bond and the potential for repair failure.
  • Typically, bond strength is very important. Failure is defined by the repair material not bonding to the concrete matrix. Therefore, the preparation of the concrete surface is vital to success.
  • Even dimensional characteristics of the repair material are important since drying shrinkage will affect the repair’s bond. If the area being repaired will be under load, the elastic modulus should be similar to the repair material. In addition, the thermal coefficient, which is the rate at which material expands and contracts due to hot and cold temperatures, should be similar.
  • With cold winter temperatures in New Orleans, the repair material should be resistant to freezes and thaws.
  • Consider water vapor transmission, as well. When there is pressure from water vapor within the concrete matrix, the overall pressure can reach a point of causing a problem with bonding of the repair material.
  • Are flexible strength, compressive strength, and abrasion resistance important considerations?

After considering each factor, your Sundek of New Orleans contractor can choose the right material to repair your cracked concrete.
