Many homeowners would like to convert their existing outdoor slabs into sun-rooms and enclosed patios but there are a few things to keep in mind about the concrete once the outdoor becomes indoor living space. Shawna Turner, General Manager at Direct Colors, is here with us today to talk more about patio conversions and what to look out for.
Tommy C: You’re listening to LISTEN.DIRECTCOLORS.COM podcast episode number 27, How-to Successfully Acid Stain Side by Side Concrete Slabs Poured at Different Times. If this is your first time listening, then thanks for listening. I’m Tommy Carter, Sales Manager and Technician with Direct Colors. It may sound odd that concrete poured at different times would not acid stain the same but if you’ve added on to your patio, interior floors or driveway, this podcast is worth the time spent listening! Here to tell you more about why and how to get the best results from your next DIY project is Shawna Turner, General Manager with Direct Colors. Welcome to the podcast, Shawna.
Shawna T: Thank you.
TC: Let’s get started. So why does it matter if side by side concrete slabs are poured at different times if you’re planning to acid stain?
ST: Acid Stain is a chemically-reactive stain not just a topical colorant. The stain relies on the minerals available in the concrete surface to react properly and develop the variable, rich color acid stain is known for. Concrete is not mixed exactly the same way every time and the mineral content can vary substantially from one batch to another. Concrete finishing, especially if a machine trowel is involved, can alter acid staining results dramatically from one floor section to another as well. Keep in mind that exposure to the elements can impact color development on older outdoor concrete slabs. In addition, concrete patches will also stain differently from the surrounding concrete and should be given special consideration before beginning a project. More to this subject than you thought, I suspect.
TC: For sure! What recommendations would you make for indoor floors poured separately or patched due to plumbing problems or for carpet tack holes for example?
ST: For indoor floors, making sure the profile is the same across the slab is important. Whether you choose to mechanically profile the floor using a sander or chemically profile with our Hard Troweled Floor Prep, do the same thing everywhere. I recommend reading over page one of our How to Acid Stain Concrete Guide to determine what process will yield the best results for your concrete before beginning. As for concrete patches, they can be tricky particularly if they are in a conspicuous area of the floor. Patches should be sanded flush with the floor before staining. For best results, I would stain and neutralize the rest of the floor first leaving the patch to be stained afterwards so it can be more easily color matched by carefully controlling the stain’s activation time. Once the patch achieves the same color as the floor, neutralize the stain and move on to the cleaning step. Spray both the patch and the floor with water from a handheld spray bottle to determine when the matching color has been achieved prior to neutralizing. Keep in mind that we offer topical stains, such as DCI Concrete Dye and Liquid Colored Antique Concrete Stain, to touch up or further accent any difficult areas so don’t worry, there’s more than one path to a beautiful floor.
TC: That’s good news. What about outdoor concrete?
Many homes have patio and driveway slabs poured at different times. If you want the concrete to be as close to the same color as possible, I suggest applying the stain to the older slab first and leaving it to process for up to 10 hours for maximum color development. The longer concrete is exposed to the elements, the more surface mineral erosion occurs. For this reason, older concrete needs more processing time to achieve optimal color results than a newer slab. After the processing time is complete, neutralize the concrete and rinse so you can get a good look at the color. At this point, apply the stain to the newer slab and leave to process for 2-3 hours. Using a spray bottle of water, dampen a small area of the old and new concrete and compare. If it looks like a good match when wet, great. Neutralize and clean the entire slab in preparation for sealing. If not, let the new concrete process for another hour and repeat the test until a color match is achieved. Remember to look at the concrete only when it’s wet not dry. Dry, acid stained concrete does very little to reveal the final color as it will appear when sealed.
TC: What happens if a color match can’t be achieved with the acid stain? What else can be done?
ST: As I mentioned before, we have several topical stain options for indoor and outdoor use. I most frequently recommend our Liquid Colored Antique Concrete Stain for patios, driveways and other outdoor concrete. It can be used as a stand-alone concrete stain and often is or as an accent for acid stained concrete. If a satisfactory color match isn’t achievable, Liquid Colored Antique can be applied to blend the colors and create a more uniform final result. Customers often use this to color match on existing stained outdoor slabs where repairs have been made. It’s really an excellent, easy to use product that can renew color, fix problem areas and save customers a great deal of money by avoiding unnecessary tear-outs and refinishing.
TC: That’s great to hear. Everyone likes to save time and money on home improvement and want to successfully acid stain concrete slabs. Thanks, Shawna, for the helpful tips on how to get the best results when acid staining interior floors and outdoor concrete. I’m sure this will useful information for many of our customers.

Acid Staining Interior Floors
Staining Older Concrete Patio
Tips on Converting Patios into Indoor Living Space
Shawna T: You’re listening to LISTEN.DIRECTCOLORS.COM podcast episode number 26, Successfully Staining Older Concrete. If this is your first time listening, then thanks for listening. I’m Shawna Turner, General Manager with Direct Colors. This week our Senior Sales Manager and Technician, Justin Richardson, joins us to talk about how to get the best staining results out of an older concrete slab. You may have seen Justin featured in two videos covering this topic on our website, Facebook and YouTube. He’s got some great ideas to share with you today so let’s get started. Welcome to you, Justin.
Justin: Hi Shawna. Thank you.
Shawna T: What challenges should customers expect when staining older concrete?
Justin: Those challenges will vary depending on whether the project is an indoor floor or outdoor concrete. Interior slabs become harder and denser over time requiring either mechanical or chemical profiling to open the pores and allow the acid stain to readily penetrate the concrete. DCI Hard Trowel Floor Prep is a safe, easy to use product for chemically profiling concrete floors. This will give your best acid staining results on older concrete especially concrete where water does not soak easily into the concrete. Older outdoor concrete will erode over time with exposure to the elements losing some of its surface “cream” which is essential to successful acid staining. If you do have exposed aggregate or sand, that does not mean you can’t acid stain but you may want to apply topical concrete stain like our Liquid Colored Antique to enhance the color after the surface has be neutralized, cleaned and dry and before sealing. Take an honest assessment of your concrete before staining to make sure you have the products you need to do the best job possible.
Shawna T: Which products do you most commonly recommend for older concrete projects?
Justin: There’s no reason you couldn’t use acid stain on older concrete. It’s one of my personal favorites because it permanently changes the color of the concrete and our customers use it all the time. Sample testing on the slab with proper surface preparation is very important for older concrete projects to make sure you’re going to get the color results you’re looking for. It’s more difficult to achieve a marbled acid stain look on heavily textured, weathered, or rough exterior concrete. Consider using two colors to create more color contrast and movement on the slab. If sand or aggregate is a problem, another option for really beautiful results is the Liquid Colored Antique after you’ve applied the acid stain. After completing all the acid staining steps, apply the antique to dry concrete in a contrasting color to darken the color or accentuate features like cracks enhance appearance. It’s very easy to use. Shake very well, pour into a Fence and Deck Sprayer and apply. Please see our video of a similar application on our website.
Shawna T: What application techniques would you suggest to enhance the finished look and overcome imperfections?
Justin: I have a couple of suggestions. On interior slabs, no matter what you’ve get color variations on the concrete even if you apply a saturating even coat of acid stain. Existing imperfections in the concrete will not be hidden by acid stain but sometimes those imperfections will work to your advantage instead of against it. Our acid stains, particularly the Coffee Brown, can be diluted with water for the first coat and applied full strength for greater color and texture variation. Older, weathered concrete could definitely benefit from using Liquid Colored Antique to improve the color outcome.
Shawna T: What advice would you offer customers about sealing older concrete and which sealer would you use?
Justin: When it comes to sealing concrete, you have options. Direct Colors offers both solvent and water based acrylic sealers. Solvents are easier to apply and always make the color “pop” more but because of odor, you have to be very careful about using them indoors. Solvents can also be applied anywhere above freezing and under 85F. Sprayable Satin Finish Sealer is our most popular outdoor sealer and Krystal Kote High Gloss Water Based for interior. Water based Sealers are preferred for indoor use for their low odor but they can’t be applied below 60F at any time. Acrylic sealers are by far the easiest sealers to apply indoors or out and comprise about 90% of the DIY homeowner market for that reason. Please check out our range of sealers on our website and consider your gloss expections as well as the location of the project carefully before selecting a sealer.
Shawna T: Any final thoughts for our DIY audience?
Justin: Don’t let a project intimidate you. Start small with a patio or an office. Don’t rush or short cut the process. Follow the instructions and sample test on the slab you intend to stain. Take you time. It’s kind of a fun process. Take advantage of the customer services available at Direct Colors. If you prefer not to call about your project, send us a free online design consultation and we’ll get back to you within 24 hours. If you would like to call at 877-255-2656, we have technicians on duty M-F, 8:30-5pm. We’d be happy to visit with you about your project and recommend the best products for your use.

Without question, spring is the time of year when things around the house need to be done before it gets too hot. Don’t let the idea of doing-it-yourself overwhelm you. Our technicians are available by phone at 877-255-2656 or by email at firstname.lastname@example.org to answer questions and help you get started. Until then, here are a few helpful tips for first-timers to DIY decorative concrete:
#1:Start small… You don’t have to remodel the kitchen as your first project. Begin with concrete decor for the garden like statuary or a birdbath to get your feet wet and get accustomed to the products. Experience as we all know is the best teacher. We offer several how-to videos on concrete décor projects that might be useful as a starting point. We also have extensive photo galleries that include a variety projects featuring all our color products. Hopefully our customers will inspire you with their DIY skill and help you select an appropriate project for your own home.
#2:Try some samples… If you are considering a larger project, such as refinishing a countertop, check out our samples and kits page first. We have concrete overlay samples, acid stains and pigments that you can create a sample board with to work on application technique and color selection. If you have a flooring or outdoor concrete project, we offer individual samples and kits to test for concrete reactivity in the case of acid stain or deco gel acid stain and to generally make sure the product is a good fit for your project. Working with samples before beginning with a larger project makes a big difference in your comfort level.
#3: Patios are our #1 project… If you want to try a flooring project, start outside. Patios are the easiest concrete project to complete and are most commonly what our customers cut their teeth on so to speak. We have some awesome step-by-step how to guides that will really boost your confidence about doing DIY projects yourself. Walkways, Driveways and Porches are also good options for first time projects. The products we recommend most frequently is acid stain and for previously colored and sealed concrete, Liquid Colored Antique. Both are great and with good application instructions, easy to do. Once you finish the outdoors, next indoor floors and countertops!
#4: Check out the How-to videos, podcasts and blog posts… Take the time to review the DIY experiences of others before proceeding. Good preparation is never wasted time. DirectColors.com and listen.directcolors.com offers a wealth of information on just about every decorative concrete project.

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.
