Podcast: Advantages of Acid Staining Concrete Floors

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  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!

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?

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.
