You’re listening to DIRECTCOLORS.COM/LISTEN 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: You’re listening to DIRECTCOLORS.COM/LISTEN Podcast Episode 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.

You’re listening to Direct Colors podcast Episode 37: Acid Stain Concrete Indoors and Out! If this is your first time listening, then thanks for joining us.  Acid Stain Concrete is a popular option for both floors and patios but what are the acid stain pro’s and con’s and how do homeowners or businesses know if acid stain is the right choice for their project? That’s when Direct Colors can help! Here to talk about the options for acid stained concrete is Direct Colors General Manager, Shawna Turner. Welcome back to the podcast, Shawna.

ST: Thanks, Tyler.

TT:  So, what are the advantages of acid staining concrete floors and patios?

ST:  Without question acid stained concrete makes outdoor concrete look beautiful and increases your home’s overall curb appeal.  Acid Stain is a chemically-reactive stain that permanently alters the color of the concrete which is particularly beneficial for patios or other outdoor concrete exposed to weather and wear over time. As for concrete floors, I think our customers probably appreciate the ease of cleaning and low allergens the most over time, especially if they have pets. Every acid stained floor application is unique and really gives your home a stunning look without being ridiculously expensive.  Acid Stain, Sealer and Floor Wax are a very durable flooring system that will give you many years of use without refinishing or stripping.  I stripped out the carpet in my home about 7 years ago because of allergies and I was just sick of carpet in general. I used DCI Concrete Overlay to create some texture on the floor, acid stained with Shifting Sand Acid Stain, highlighted with Sorrel DCI Concrete Dye and sealed with both DCI Water Based Sealer and finally, the 550 Glossy Polyurethane. My floors still look great and I’ve never done more to clean them than a mop and a very light dishwashing soap and water solution.  A huge improvement over carpet I can tell you!

Acid Stain Concrete Floors

Acid Stain Concrete Floors

TT:  Since Acid Stain is a chemically-reactive stain, I would think the quality and condition of your concrete would be important. How do you know if acid stain is a good choice for your project?

ST:  That’s a very good question. It’s true that not all concrete is a good candidate for acid staining. Sometimes concrete floors, especially in basements and garages, are too smooth to acid stain and need to be profiled or in the case of outdoor concrete, patios are too eroded to get a good reaction with the stain. We have a comprehensive guide on our website to help DIYer’s determine if their concrete is ready for acid staining or not. The first page of the guide has a short list of questions and tests that if followed, significantly reduce the chances of problems during the process. We also have guides acid stain concrete guides specific to our most popular projects, including patios, basement floors, concrete floors and garages. We try to provide design tips and product recommendations to our customers that will help them get the best results with the least aggravation possible. Of course, doing a test area on the actual concrete first using acid stain samples does confirm whether the acid stain will react well with the concrete or not and we highly recommend testing before ordering product for the larger project.

TT: That makes good sense.  If I were a first-time DIY’er starting with a small acid stained concrete floor or patio project, what would you recommend?

DIY Acid Stain Kit

 DIY Acid Stain Kit for Homeowners

ST:  Most of our DIY homeowners begin with a patio or possibly bathroom acid stain concrete floor project. Both are manageable in size and scope for most handy individuals. With this in mind, Direct Colors created the DIY Acid Stain Kit for Homeowners that includes all the tools and products needed to complete a 200 sq. ft. indoor or outdoor acid staining project. In fact, we just recently finished a brief video describing the kit contents and how to use them. I’d encourage new customers to check out that video to get a better idea of what’s needed for the project. If you have a slightly larger patio or floor, we also have a DIY Acid Stain Kit Add-on that has the cleaner, neutralize, acid stain and sealer for an additional 200 sq. ft. available as well. That’s handy.

TT:  We haven’t really discussed sealer options but how would you choose between the sealers available in the kit?

ST:  As a general rule, I recommend using water based sealers indoors and the Sprayable Satin Finish Sealer outdoors. Water Based Sealers, either high or satin gloss, are low odor and can easily be applied even in an occupied home or basement with little ventilation. Having said that, we do have a number of customers that really want a wet-look, high gloss sealer and prefer to use our AC1315 High Gloss Solvent Based Sealer. That’s fine as long as there is excellent ventilation to the outside during application and the customer is wearing a respirator to apply. Safety first! AC 1315 can also be used outside but I’d reserve that for heavily textured, porous or stamped concrete. Our Sprayable Satin Finish Sealer is a better choice for smoother outdoor concrete, especially around pools or on any surface that could become slippery when wet and that includes garage floors.  This sealer looks great, is very durable and won’t turn your concrete into an ice skating rink when wet which is very important to most homeowners.  Now if you’d prefer a matte concrete finish, the DCI Penetrating Lithium Hardener Sealer can be used on floors or outdoor concrete and is a great deal on patios, driveways and garage floors in particular because it’s a one-time application sealer and very salt-resistant. For folks living in very cold climates, that’s a valuable selling point for sure.

TT:  That’s extremely helpful information and will no doubt inspire DIYer’s to get started with their first decorative concrete project. Don’t forget to check out our new video, Unboxing a DIY Acid Stain Kit, on our website,, or on youtube. If you have questions about your project, call one of our expert technicians at 877-255-2656 and we’ll help you select the best products and technique for your needs.  If you prefer email, send in a free online design consultation and we’ll get back to you within 24-48 hours.
