Acid stained concrete countertops offers a one-of-a-kind finish unique to this process. Because countertops are generally smaller projects, acid stain may represent one of several color techniques used to create beautiful kitchen, bathroom, table and outdoor countertops.

Step 1: Selecting the Right Concrete Mix

Finding the right mix can be more challenging than you might think. If you’re planning to acid staineda countertop, choose a countertop mix with less than 10% fly ash. Fly ash affects reactivity and color development when acid staining and causes color variability in integrally colored countertops. Direct Colors Concrete Countertop Mix contains no fly ash and producing optimal acid staining results.

Step 2: Not All Form Releases are Created Equal

DC Countertop Form Release is colorless and leaves no trace of residue on the countertop surface. Other release agents like oils or solvents will leave a film on the surface that makes acid staining impossible. Don’t use them. Remove the countertop from the forms and clean the surface thoroughly with a solution of organic degreaser and water. Rinse and allow to dry.

Step 3: Concrete Too Smooth to Stain?

Pre-cast countertops are often poured on melamine and can be too smooth to successfully acid stain. Sand the surface with a 200-grit sanding pad to open the pores prior to staining.

Step 4: Acid Staining

Apply acid stain using a pump-up sprayer or foam brush and the deco gel with a foam brush, artist brush or plastic trowel. If a darker color is desired, leave the stain on longer than the minimum recommended processing time.

Step 5: Neutralize Acid Stain

When the color has been achieved, neutralize with a baking soda and water solution, clean well and leave to dry.

Concrete Countertop Tips:

If you’re pouring a countertop, frame one or two 1 ft. x 1ft. pieces for color and to practice your technique. Sample trial sizes are available for acid stain, deco gel and penetrating hardener sealer testing purposes. Visit our concrete countertop supplies page for our entire product line.

If you’re pouring multiple countertop pieces for installation in the same room, use a timer so the acid stain or deco gel  processes on each piece for the same length of time. Extra time on the concrete generally results in a darker color.
