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.
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. We want you to be successful so get in touch!
Shawna T: Thank you for joining us today, Justin, and for the helpful advice on staining older concrete. Many of our customers have projects like this and are afraid the results won’t justify the work or expense. I hope we’ve changed some minds with this podcast and our listeners will give patio or porch project a try!

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.
