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.

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.
