Concrete Acid Stain |Certain Color Changes

RAC Azure Sky Concrete Acid Stain

RAC Azure Sky

Four of our Concrete Resurrection Reactive Acid Chemical Stain colors (RAC) have an asterisk beside them in our catalog and on our website. We often get questions about that, and we’d like to share the answers.




RAC Summer Wheat Concrete Acid Stain

RAC Summer Wheat

Which RAC stains have the asterisk beside the color names?

Olive Mist, Azure Sky, Mossy Oak and Summer Wheat


RAC Mossy Oak Concrete Acid Stain

RAC Mossy Oak


What does the asterisk mean?

It means those four colors are for interior use only because they contain copper atoms. All of the other RAC colors are for indoor or outdoor use.


What happens if I use one of the four marked colors outdoors?

Maybe nothing out of the ordinary. On the other hand, the outdoor concrete may turn a SHADE OF BLACK that may or may not be ugly depending on your point of view. It’s probably NOT what your customer was looking for though, or you either since it’s a permanent condition. Don’t risk it.

RAC Olive Mist Concrete Acid Stain

RAC Olive Mist

What causes the color change?

Oxidization causes the lovely color you started with to turn black. Outdoor slabs usually don’t have a vapor barrier underneath them so moisture from the ground migrates up through the concrete. When the water molecules reach the concrete acid stain, they react with the copper atoms in It and oxidize.

Could this same reaction take place on an interior floor?

Yes, if there is excessive moisture present. Interior floors usually have a vapor barrier though, and that prevents the problem. Always test the concrete with a moisture meter before you take any job regardless of the stain color. Know what you’re dealing with before you begin.

Concrete Transformed | Sell More, Protect Earth

decorative concrete remodelConcrete is a wonderful building material. Problem is, it’s a huge reservoir of energy. Engineers call it embodied energy. It’s the energy used to mine the limestone, grind it into a powder, mix it with water, bake it, grind it into a powder again all while transporting it numerous times.

According to a recent article in Concrete Construction magazine, “Concrete produces 5 percent of global CO2 emissions – as much as the entire country of Russia.” That’s huge!

Why are we telling you this? Each of us in the decorative concrete industry should understand our resources and their impact on the world. Sharing that info with your clients may convince them to remodel rather than replace their concrete. That’s…

  • Good news for you because you’ll earn a profit,
  • Good news for the client because they’ll soon have lovely, durable decorative concrete, and
  • Good for the environment because many potential CO² molecules will be eliminated by not requiring new concrete.

That’s not even considering the fossil fuels used or the emissions from tear outs, bringing in new, and disposing of the old.

Your Successful Website | 10 Important Tips

Website 2 editHaving a website for your decorative concrete engraving business just makes sense. Dollars and cents, that is.

Whether you design your site using one of the do-it-yourself website builders (and there are some good ones out there) or hire someone to do it for you, there are some important components to include.


First and foremost, tell and show your customers what you can do for their dull, gray concrete. This is your place to shine. If you don’t, your prospective customer likely won’t bother with the rest of your site.

What is noticeably missing from so many decorative concrete homepages is the physical location of your business or the area you serve. For crying out loud, where are you? State? City? As a customer, how can I know if you’re close enough to my project to even request a bid from you.


Provide as much information as you can about the decorative concrete engraving services you offer. Include images of jobs you’ve completed, and/or use the images we provide to those who are certified Engrave-A-Crete installers


Nearly every website contains an email contact address. A response form is even better. Make yourself as easy to contact as possible.

Be sure your location, including your city and state, and your phone number appear prominently on this and as many of your other pages as possible. Make yourself easy to find. Did we already say that?


Customers want to know who you are and why they should buy from you. Include a picture of yourself. Even better, use a picture of yourself next to one of your drop-dead gorgeous decorative concrete installations.

A brief bio, the story of how you came to be in decorative concrete engraving, your qualifications, even details about your staff members will help prospective customers get to know you.


This is an important section! Savvy shoppers today rely on testimonials and reviews to help them make informed decisions. Include as many as possible.


Prospective customers love a well-stocked gallery of decorative concrete pictures. Show each type of concrete engraving you offer – tile, wood plank, geometric designs, custom logos… For good advice on taking the best pictures of your jobs, see our blog post “Great Decorative Concrete Photos |9 Helpful Tips.”

  1. FAQs

This is another popular section. Anticipate what questions prospects may have and answer them before hand. Engrave-A-Crete installers can find an extensive list of FAQs on our website to help you build your page.


Include links to your Facebook business page (surely you have one,) Instagram, Twitter, and LinkedIn accounts. Social media is a great way to showcase your skills and connect with prospective customers.

  1. BLOG

Blogging keeps your prospects and customers interested, and that can easily translate into another job. Exactly what you want to have happen!


Fresh pictures and content help others see you as on top of things.

Having a website for your decorative concrete business is essential in today’s digital world, but it doesn’t have to be difficult or expensive. An effective website can more than pay for itself.

4 Ways to Care for Decorative Concrete | Be a Teacher

blog teacher cartoonEducating your customers on how to care for their interior engraved decorative concrete once you’ve finished the job is important in two ways.

First, it’s important for the customer to have a floor that remains attractive. They’ve paid you well, and they deserve a beautiful surface that lasts a lifetime.

Second, it’s important to you. Your reputation as a decorative concrete installer is at stake. Your customer, and everyone else who sees it, will blame you if the concrete becomes scratched, stained, or fades. Word of mouth advertising – whether it’s good or bad news – travels quickly and carries a lot of weight.

Educate your customer about the proper care and maintenance of the surface using these simple steps.

1. Entry Mats

A good scraper mat outside each entrance removes debris such as sand, pebbles and mud that can scratch or mar the concrete surface. Interior mats help stop dust and moisture before it can be deposited on the floor. Just be certain that interior mats do not have a rubber backing that may cause an unsightly and difficult to remove hard mineral deposit on the floor.

2. Furniture Pads

Avoid nasty scratches from chairs, tables and other furniture by using felt pads and tap-in protectors. Urge your customers to use them.

3. Regular Cleaning

Dust mopping and damp mopping are essential. Just as tiny particles of sand on sandpaper wear away a surface, grit carried in from outdoors will wear away the finish on the floor as it’s repeatedly walked on. Also, caution your customer to clean up spills as quickly as possible.

Use plain water or a neutral cleaner when mopping. NEVER use bleach, vinegar, ammonia, pine oils or high phosphate cleaners since they can be corrosive to the finish.

4. Reapply Floor Finish

Explain to your customer that floor finish is the maintenance top coat applied to protect the sealer and add shine. It will usually need to be reapplied once or twice a year, depending on the amount of traffic on the floor.

Make a note to check with your customer when it’s time to reapply Concrete Resurrection  Floor Finish. It can mean some extra income for you.
