Haven't used the stain just yet, but more happy with their customer service. Had a little mixup with the shipping, but they were super quick to fix and get to me! Thank you guys!
We used the Deco Gel Acid Stain Gel to create a beautiful rustic concrete countertop look.
You guys are awesome. Love your acid stain, deco gel and concrete pigment products and all the help. Here is my latest concrete bench creation and wanted to share it with you. Maybe you would like to use it as a featured project or something.
“I’ve ordered Deco Gel Acid Stain and Concrete Pigments from Direct Colors before and have been happy with their products. They have great customer service so give them call or shoot them an email and see what they suggest!”
I found your Deco Gel acid stain gel while searching on the internet. What a great product. Will certainly find many more uses for it. Deco Gel is cleaner and easier to apply with less prep work to the surrounding areas. I have included a couple of pics that just don’t do justice to the actual finish look. It was awesome and my customer was thrilled. This is an exterior shower stall/bath house at the cottage. I used your Cola and Coffee Brown Deco Gel stains. Thanks for all the technical help. Thanks again and looking forward to new products to try!”
“I was scouring the internet looking for a quality garage floor coating and stumbled upon your website. I’ve used your products on a few home projects and absolutely love them. I have told numerous people about the Deco Gel Acid Stain and Liquid Colored Antique. The potential for Direct Colors product line is limitless and speaks for itself in the photos. Thank you!.”
Direct Colors was very helpful and offered advice on how to get the mottled look I was trying to achieve. The process was simple and the Deco Gel Acid Stains were quite easy to work with. I am pleased with the final appearance of the projects and look forward to many years of enjoyment using the countertops.

  • Cleanup: Baking soda and water
  • Coverage: Approximately 150 - 200 sq. ft. per gallon depending on concrete porosity

Note: Since this is a made to-order-product, we cannot offer refunds, exchanges, or returns.
Due to DOT-ORM-D regulations, this product cannot be expedited and can only be shipped by ground.

Step 1: Surface Preparation 

  • Cover areas at risk of over-spray with plastic drop cloth 
  • Newly poured concrete must cure for 30 days prior to application 
  • For existing concrete: 
  • Verify absorption by pouring a cup of water in various areas. If not absorbed within 5 minutes, etch the surface with Hard Troweled Floor Pre-Treatment or mechanically etch with a floor sander or grinder 
  • Rinse thoroughly and allow the concrete to dry before stain Application 


Step 2: Application 


Coverage rate is approximately 200 square feet per gallon. Coverage rates may vary based on concrete texture, porosity, and application method. 


NOTE: DecoGel™ should be acclimated to ambient temperature. Before applying, surface temperature must be above 40°F (4°C) but not over 95°F (35°C). 


Applying DecoGel 


  • Apply a generous coat using a foam brush, foam roller, artist brush or plastic trowel 
  • Allow the stain to develop color over time, usually 4-6 hours. (Darker colors may take longer) 
  • Once desired color has developed, remove excess DecoGelTM and neutralize the stained surface using either baking soda and water or ammonia and water:  
    • Baking soda: 2 tablespoons per gallon of water 
    • Ammonia: 1/2 cup Ammonia per gallon of water 
  • Spray a saturating coat of neutralizer onto stained concrete. Allow to sit for 15-20 minutes 
  • After 15-20 minutes, use a scrub brush and water to scrub the surface completely clean of all stain residue 
  • Continue cleaning and rinsing until the rinse water runs clear. For interior applicationsuse a shop vac to remove rinse water 
  • Allow cleaned surface to dry thoroughly before sealing 
  • As the floor dries, the color will begin to look chalky and faded. This is normal and should not cause concern. The color will “pop” once sealer is applied 


Step 3: Seal

Pro Tips: 


  • DecoGel™ will only react with the Portland Cement in your concrete, not exposed aggregate or sand particles 
  • Some colors vary more than others. Many factors determine how the color will turn out, such as age of concrete, cement content, and weathering 
  • Use soap, baking soda, and water to clean tools and equipment. Use up or dry out extra material and dispose of it according to local regulations. Do not pour into sewer systems or storm drains 
  • If applying more than one color, begin with the darkest color accents, applying where you wish to see them. Then apply the lighter colors over the entire area
