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. 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.

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!

Tommy C: Thank you, Shawna, for that detailed information about acid staining floors during construction. I know it’s a common planning question with our DIY customers. Check out our blog for more on the Care and Maintenance for Acid Stained Floors and other decorative concrete flooring projects.

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 use the same pigments in our Liquid Colored Antique and Tinted Concrete Sealers so each product can be used outdoors and if well maintained over time, the color will not fade with exposure to sunlight.

Lisa: Thank you, Shawna, for the information about what projects concrete pigment can be used for. Here are few blogs post on the subject from our website, www.directcolors.comColor Stucco and Plaster with DCI Concrete Pigments, Top 10 Uses for Professional and DIY Concrete Pigment and Integral Color and Concrete Pigment for Tile Grout Color and More. A little something for everyone.

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.”

Thanks Isaac! Your floor looks amazing!

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.

AN:  There are several concrete calculators on the website. Which calculator should a customer use for these mixes as opposed to concrete?

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.

Coloring Grout, Stucco, Plaster and Mortar

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.
