Tommy C: You’re listening to LISTEN.DIRECTCOLORS.COM podcast episode number 24. If this is your first time listening, then thanks for coming. I’m Tommy Carter and today we’re talking about acid staining floors during the construction. As acid stained floors have become more popular, homeowners need to know when to acid stain and what to do to protect the finish throughout the construction process. Shawna Turner, General Manager, with Direct Colors is here to give us the scoop on new construction staining projects. Welcome, Shawna.
ST: Thank you very much
Tommy C: What’s the first thing to keep in mind when acid staining floors in a new construction home?
ST: Probably the first thing is to make sure your General Contractor knows and understands that you plan to acid stain the floors. If he or she knows in advance, they can properly direct the ready-mix company pouring and finishing the concrete as well as other building contractors to act accordingly.
Tommy C: What role does the pouring and finishing of the concrete play in successfully acid staining?
ST: If you plan to acid stain concrete, the mix should contain no more than 10% fly ash and should only be lightly machine troweled if at all. The concrete should be rich in cement content and the pores open for the stain to readily absorb and react. As long as the GC knows in advance, these requests should not be difficult or costly to implement.
Tommy C: When should a homeowner plan to acid stain their concrete during construction?
ST: The concrete should be allowed to cure for 30 days for best staining results. If at all possible, the concrete should be stained after the dry wall has been hung but BEFORE it has been mudded in. The reason this is so important is that dry wall mud is a very challenging contaminant to remove from concrete after the fact. Homeowners wishing to acid stain their floors are then forced to spend a lot to time and money cleaning that could have been entirely avoided. Spray insulation is also a problem. Spray insulation should be installed AFTER the floors have been covered with overlapping cardboard. The chemicals interfere with the staining and sealing process and are notoriously difficult to remove.
Tommy C: Just to be clear, could you give us the step by step process from acid staining to waxing?
ST: Sure. That’s a good idea. Once the dry wall has been hung, clean the floors thoroughly using a medium to heavy duty organic degreaser and water solution. All debris, particularly chalk lines, paint, oil stains, dirt and the like, has to be off the surface and out of the pores before you begin. Sanding may be necessary for stubborn debris and staining. When the floors are clean and dry, apply the stain, neutralize and clean according to the instructions. Leave the floor to dry. At this point, you really only want to apply one coat of sealer. I recommend our Sprayable Satin Finish Sealer, especially if you’re working in the winter months. It does have a strong odor during application but can be sprayed on floors freezing and above.
Tommy C: Why just one coat of sealer at this stage?
ST: Even when you cover the floors with overlapping cardboard, damage can still be done during construction. Once the work is complete and the floor cleaned, another coat of sealer can be applied to repair any existing damage and make the floor look brand new again. The sprayable satin finish or AC1315 High Gloss are both solvent-based and have the ability to re-emulsify the acrylic for a smooth final coat.
Tommy C: So what are the final steps after applying the sealer?
ST: After the sealer has been successfully applied, allow the concrete to dry for at least 10 hours before covering with overlapping cardboard. DO NOT TAPE THE CARDBOARD TO THE FLOOR. Tape will bond with the sealer and ruin the finish. Keep the floor covered until construction is complete and the baseboards are ready for placement. At this point, you’re ready to remove the cardboard, clean the floor and apply your final coat of concrete sealer. Allow for 24-48 hours ventilation and dry time before applying the concrete wax and floor polish according to the instructions.
Next step: Enjoy your Floors!

Concrete pigments can be used for a lot more than just slabs. Our customers buy Direct Colors pigments for everything from decorative planters to warehouse slabs and just about everything in between. With more on the many uses for DIY concrete pigment is Shawna Turner, General Manager, with Direct Colors. Welcome, Shawna.
Shawna: Thank you very much
Lisa: So let’s have it. What’s the most popular use for concrete pigment?
ST: Without a doubt, it’s concrete slabs of every kind. If you’re just looking for a solid, rich color in your concrete nothing better than concrete pigment. It’s a stress-free color option and really the only thing the home or business owner has to do is seal the concrete after 30 days curing time. Integrally colored concrete is very popular for outdoor concrete, especially stamped concrete, but it’s increasingly popular for interior floors as well because it’s cost effective, easy and low maintenance.
Lisa: Please explain the difference between concrete pigment and integral color. Is it the same thing?
ST: Yes, it is but I can see were the terms might be confusing. Concrete pigment is a powdered pigment added to concrete prior to pouring to integrally color or color the concrete throughout. Because the concrete is integrally colored, the color is still visible even if the surface is damaged or chipped. The color really is permanent though it can fade somewhat overtime if not properly sealed.
Lisa: What are some other popular options for concrete pigment?
ST: I think concrete countertops are probably our second most popular project. Customers choose concrete pigment for countertops for the same reason as floors – easy to use, consistent color and good selections of color options. Pigment can be used in either a poured concrete countertop or in our concrete overlay. Our most popular concrete countertop color is by far our 15.4 Premium Blue Pigment followed by the 230 Black pigment. People really love their blue and black countertops.
Lisa: Can you use pigment for grout, mortar or other finishing materials?
ST: Sure. We get a lot of calls for custom grout colors in particular but concrete pigment can be used with any cement-based material. Stucco is also very popular. We offer a wider color selection than can be found at most big-box stores and we sell direct to the public. It’s difficult for DIYer’s looking for smaller pigment quantities to find affordable products locally or online. We have three varieties of blue concrete pigment for sale on our website, www.directcolors.com, which is a challenging color to find generally.
Lisa: Is there anything special about Direct Colors pigments that sets them apart from other products on the market?
ST: Why of course! Seriously though, it is important to choose pigments according to their use. Our pigments are UV stable and chemically inert so they can be used outdoors as well as with many different cement-based materials. Pigments that are not UV resistant will fade and deteriorate with exposure to sunlight. Because our pigments are non-reactive, they can be safely added to integrally color most any cement-based material. Keep in mind that all outdoor projects should be sealed with a quality concrete sealer and most indoor projects. Sealing protects the surface from undesirable staining, makes clean up easier and darkens the concrete color overall.

We recently had the opportunity to provide product to a local tattoo shop project. Isaac Bruno of Mad Tatter Tattoo Shop is with us today to chat about how he created this epic red and white checkerboard floor created with DCI Concrete Dye!
“My name is Isaac Bruno. I just opened up the Mad Tatter Tattoo Shop in Shawnee, Oklahoma. I was inspired by Alice in Wonderland. I really enjoyed all of the textures, all of the colors and just the imagination of everything: green trees, red trees and talking animals. It’s always intrigued me and I wanted to do something totally different so this is what I did.
We used a lot of different colors of the DCI Concrete Dyes: reds, olives, bright greens that we were working with as well. It turned out really nice. A lot of the colors we tried to use worked out really well and I really enjoyed using them. I used to airbrush t-shirts and cars and things like that, and this product worked similarly to that. It went on really quick and flashed really fast and it was really simple once we figured it out.
We did the red and white here in the lobby with this crazy checkerboard floor, then I ran it down the hallway with a little pink path and grass and weeds going up the walls. I also added a grass pattern to my room and did a little stone walkway around the chair.
I wanted to do something that messed with your mind, to make it as three dimensional as possible. The regular red and white checkerboard floor has been done before. There are a lot of places that have them. I wanted to add a little motion to the room so we made this floor.
Don’t use a masking tape or anything with a high adhesive. We had to use a low tack tape and we couldn’t leave the tape on there for very long.
One thing I had a problem with is I had to keep shaking the product so I went to the store and purchased a whisk, removed the handle and attached it to my drill. I could easily mix the product and continue my project.”
Prepping concrete for acid staining before getting started is critical to success but how this is done can make or break a project. Here to discuss how to and how not to prepare concrete for acid staining is Shawna Turner, General Manager for Direct Colors.
Amie Nolen: It seems like surface preparation is the most important step of the process. Can this be a big problem for customers if they don’t do it right?
Shawna Turner: Absolutely. Not all concrete can be acid stained but most can if the concrete is properly profiled using the correct product or method before staining. Determining which method or product is best can be the biggest challenge.
AN: Could you explain what it means to profile the concrete?
ST: Sure. Profiling the concrete simply means to change the surface texture to allow for better acid stain penetration. Profiling can be accomplished by either a chemical or mechanical means. Chemical profiling using an acid stain approved etcher such as our DCI Hard Trowel Floor Prep will open the pores without interfering with the later acid staining process. Mechanical profiling would involve a concrete sander or grinder which might be used on extremely smooth or heavily contaminated floors. For example, floors with glue, paint and drywall mud over most of the concrete should probably be mechanically profiled using a grinder because the cost of a chemical strip would be greater than the cost of renting the machine.
AN: What products should not be used to profile concrete?
ST: That’s a pretty easy question to answer. If the etcher is intended for use with anything other than acid stain, don’t use it. That would include water based stains, sealers, epoxy coats, paint and anything else not specifically called acid stain. Acid based cleaners and etchers used in conjunction with other coatings actually dissolve the minerals in the surface of the concrete necessary to support the reaction between an acid stain and the concrete. Without those minerals, the acid stain will sit on the surface and be washed away later in the cleaning process. So if you have previously cleaned your concrete using a muriatic acid and water solution, the slab will either not stain at all or stain very unpredictably depending on how the solution was originally applied and how strong it was. I really can’t emphasize enough that you’ve bought a concrete etching product from a local big box store, don’t use it if you want to acid stain later. Really that’s the bottom line.
AN: Ok. That is straight to the point. How would a customer know aside from obvious surface contaminants that their concrete needs profiling in the first place?
ST: Most indoor concrete and some outdoor poured in the last 10-15 years was likely finished using a machine trowel. We discuss this in some detail on the first page of our How to Guide for Applying Acid Stain. A simple water test will often reveal whether water will readily absorb into the concrete or bead on top. If beading does occur, the surface needs to etched using our DCI Hard Trowel Floor Prep before acid staining. Basement and garage floors are generally the smoothest floors in the house and will more likely than not require etching prior to staining.
AN: So what happens next for customers that have used an acid based etching or cleaning product on their concrete?
ST: I would recommend either Tinted Concrete Sealer or a Tinted Concrete Sealer and DCI Concrete Dye combination to create more color variation and movement on the floor similar to an acid stain finish. If you’re working with outdoor concrete, I suggest our Liquid Colored Antique and Sprayable Satin Finish Sealer. We have a wide color selection and it is extremely easy to apply. I’ve used this product at home on my walkways and patio and have been very happy with it.
If you are in some doubt as to whether your concrete will stain or not, try an acid stain sample bottle and make sure. It’s always a good idea to test the quality of your concrete regardless and it never hurts to try. You’ll find acid stain samples and samples of all our products on our website at http://www.directcolors.com/samples-and-kits/.
AN: Thank you, Shawna, for setting us straight on prepping concrete for acid staining. No doubt this will help a number of homeowners avoid a costly DIY mistake.

Many of our customers are interested in coloring grout, stucco, plaster and mortar but have a difficult time finding the right colors, especially blues, and small enough quantities. Direct Colors General Manager, Shawna Turner, is here to talk more about calculating for and mixing custom colors in these materials. Welcome Shawna.
Amie Nolen: Calculating pigment for so many different cement-based mixes sounds complicated. Is it?
Shawna Turner: It definitely can be. The difficult part is the fact that very few manufacturers report the product contents on the side of the bag. Usually the technical data sheet will include the amount of cement in the mix but that’ s not always available so we often are forced to make an educated guess that many vary somewhat from product to product.
AN: Why is the amount of cement in the mix so important for getting the color right?
ST:Concrete pigment creates color by coating the cement particles with color so other ingredients are a less important part of the color equation. The pigment needed to achieve a specific color from our color charts is based on the amount of cement only rather than the total weight of the mix. Each mix is comprised of a 3:1 ratio of sand to cement and/or lime. If lime is also added to the mix, the cement and lime should be added together for the purposes of calculating pigment load. Whether you are mixing your own material or using a pre-bagged product, having this basic information can help you to determine how much pigment you need for a project. Because grout, stucco, plaster and mortar are cement, sand and possibly lime mixes containing no aggregate, colors can appear somewhat different in fact than they are on color charts. Testing is incredibly important when working with these materials and will help avoid mistakes.
ST: The calculator most useful for coloring grout, stucco, mortar and plaster is called the Custom Batch Calculator. The Custom Batch Calculator requires two pieces of information – the weight of cement and/or lime in your mix and the pound rating for the color chosen from our concrete pigment color chart. We recommend calculating both for batch size as well as the overall project. For example, if you planned to use one 80lb. bag of stucco mix and wanted to integrally color the stucco to Cornflower. You’d enter 20 lbs. for the cement/lime content and a “1” for the pound rating to calculate the amount of pigment needed for the project which is just under a quarter of a pound (.21 lbs.) per bag.
DCI Concrete Pigment Color Chip Diagram
If you’re calculating for a sample, the pound output from the calculator is likely to be unhelpful so we’ve provided a link to other calculation options at the bottom of the page. For example, say you have about 5 lbs. of cement/lime in your mix and the amount of pigment needed for the chosen color, Royal Blue, is 0.1595 lbs. 0.1595 lbs. is a difficult number to work with so converting lbs. to teaspoons for such a small batch is very useful. Using a conversion website easily found with a search engine, we’ll need 15 teaspoons to achieve Royal Blue in 5 lbs. of white Portland mix. Calculating from lbs. to grams is also a good option. Gram scales provide more exact measurements, especially when measuring small amounts, and can be used for any small or medium sized project.
AN: What about sealing? Is it necessary in all instances?
Outdoor stucco applications should be sealed with an acrylic or penetrating densifier sealer to protect the color integrity from the elements. Some customers prefer a light shine and the easy application our Sprayable Satin Finish Sealer offers, especially for stucco projects. Our DCI Penetrating Lithium Sealer Hardener has a matte finish is perfect for grout projects where gloss isn’t all that desirable. This sealer enhances overall concrete durability and is a one-time application which is super. Sealing for interior projects isn’t necessary but acrylic sealers will deepen color appearance and add some gloss.

More and more people are interested in pouring acid stain ready concrete. Here with tips and recommendations to make that process easier and more successful is Shawna Turner, General Manager, with Direct Colors. Welcome, Shawna.
Shawna Turner: Thank you.
Amie Nolen: What’s the first thing a customer needs to do to get started?
ST: The first thing to do is have a conversation with your general contractor (GC). Make sure he or she understands your plan to acid stain and what that means for the overall construction process. Preparing to acid stain begins before the concrete is poured so it should be discussed with the general contractor in the planning stage.
AN: You mentioned preparing to acid stain before pouring the concrete. What does that mean?
ST: Well, not all concrete is created equal. Depending on where you live, concrete can contain additives and/or fly ash that negatively impact the acid staining process so it’s imperative that you know what’s going in your concrete BEFORE it’s poured. How do you do that? Either the homeowner or their contractor needs to call the ready mix company pouring the concrete to ask for the mix design details. The concrete should not include retarders, accelerators or more than 10% fly ash if it is to be successfully acid stained later. None of these additives are essential but are often used when temperatures are very hot or cold and to cut costs in the case of the fly ash. I’d also avoid using a topical curing compound unless it is self-dissipating and will evaporate within two weeks of application.
AN: That’s very helpful information. What about finishing the concrete? I know that’s also an important part of the process.
ST: You’re right. Finishing the concrete properly will yield better final staining results. The best option for indoor floors or patios is either a hand-troweled or light machine trowelled finish. Stamping or texturing concrete is fine too if you’re working outside. The objective is to avoid making the concrete so smooth that acid stain can’t readily absorb into the pores. If the stain can’t absorb, the chemical reaction will not occur and the stain will simply wash off during the cleaning process. No one wants that to happen. Overly smooth concrete can be corrected using our Hard Trowel Floor Prep product after the fact if needed.
AN: When should a customer plan to acid stain the concrete?
ST: We usually don’t recommend acid staining until the concrete is fully cured or achieves a uniform light gray color. That could occur anytime after 20-28 days depending on weather conditions. The concrete will need to be protected throughout the construction process. Overlapping cardboard works best to cushion blows and absorb spills should they occur. Spills and other contaminants on unprotected concrete only make the home or business owners job that much harder when it’s time to stain. Again, remind your GC to talk to every contractor about not marking the floor or making a mess. Covering the floor can make a big difference but nothing’s better or more effective than a conscientious contractor.
AN: In the case of interior floors, at what point in the construction process would you acid stain?
ST: The best time to uncover, clean, acid stain and seal the floors is after the dry wall has been hung but has not yet been mudded in. Dry wall mud is notoriously difficult to get off of concrete. Staining and sealing before that step is the better option for sure. Once the floors have been stained, neutralized and cleaned, apply one coat of sealer. I prefer the Sprayable Satin Finish Concrete Sealer because it’s so easy to apply and dries quickly. Six hours after application cover again with overlapping cardboard and continue with construction.
AN: At what point should the finishing coats of sealer and wax be applied?
ST: Just before the baseboards are installed, remove the cardboard, clean thoroughly and apply another coat of sealer. The second coat of sealer will repair most minor scratches on the surface and add additional luster. 24-48 hours later apply three coats of concrete wax and allow to dry for 24 hours before moving in furniture. A polyurethane sealer could also be applied after the second coat of sealer if desired. Wax would no longer be necessary in that case. I highly recommend our how to guide on care and maintenance of acid stained floors. Please give that a read before moving in to avoid unnecessary damage to the floors.

Applying acid stain and concrete sealer in the summer months can be challenging especially if you live in a hot temperature climate. Here are a few tips from our own General Manager, Shawna Turner, for outdoor concrete and countertop projects that will help DIYer’s get it right the first time.
Amie Nolen: Welcome to the podcast, Shawna.
Shawna Turner: Thank you.
AN: What are some of the challenges homeowners face when acid staining and sealing outdoor concrete in the summertime?
ST: Concrete temperature and wind conditions often determine success or failure for an acid stain project. Hot, dry conditions can cause acid stain to prematurely dry before properly reacting with the concrete. But how hot is too hot? Concrete shouldn’t be more than 75-80F for best staining results. Dry, windy conditions can wick the moisture from the concrete leaving a “blotchy” appearance behind particularly when using both light and dark colors.
AN: What can be with our outdoor concrete besides wait until Fall?
ST: Well, it’s not quite as bad as all that. The most important step for homeowners applying acid stain either late in the evening or early in the morning when concrete temperatures are at their lowest. As the day heats up, so does the concrete and air begins to pass through the surface. When temperatures are cooling, the concrete contracts and is therefore a better candidate for staining or sealing. Keep in mind that direct sunlight and ambient temperature are not the same. Lay a thermometer on the concrete surface and cover with a towel. If after 4-5 minutes the temperature is greater than 80°F, do not stain.
Another valuable tip is to lightly dampen not flood the concrete before applying acid stain to add moisture and prevent premature drying. Premature drying can retard color development and isn’t helpful if you’re working with multiple colors outdoors.
AN: What about sealing specifically? I know hot temperatures can really cause problems. What should customers be looking out for?
ST: Without question, DO NOT attempt to seal in the heat of the day. Colored concrete in direct sunlight, especially dark browns and black, could be several times hotter than the ambient temperature and just a few minutes of sunlight will raise the surface temperature very quickly. If the concrete is too hot, small air bubbles will often appear either during the application or just after. The air bubbles are formed by air rising through the concrete and becoming trapped in the sealer. The bubbles will eventually collapse leaving unattractive concave spots behind. Not very attractive, especially on outdoor kitchen countertops.
Finding the right time of day to apply concrete sealer during the summer months can be a challenge. Sealers, like acid stain, should be applied when the concrete is at its lowest temperature either early in the morning or late in the evening. East facing concrete should be sealed later in the day and west facing early in the morning.
AN: What time of year do you normally do “maintenance” on your decorative concrete?
ST: Never if I can get away with it! No, I’m kidding. I usually do my resealing in the late spring when you can get a couple of rain free days and if that fails, before winter sets in. Because I live in Oklahoma where the summers are very hot, I seldom attempt to seal my exterior concrete during the summer months. It can be done but most of the time I don’t want to get up that early.
