DecoGel™ Acid Stain is an acid-based gel of minerals and acid
designed to adhere without drips or runs to concrete walls, borders, columns or
other similar projects. DecoGel™ has been specifically designed for
use on vertical applications. When sealed with the proper sealer, the stain
produces a bright variegated surface unique to this process. DecoGel™ can
be used in conjunction with our liquid acid stain for
projects that have both vertical and horizontal surfaces.

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
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).
- 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 applications, use 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
- 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
