Though you don't have to, we recommend you seal the surface. Sealing stain concrete not only makes in look way better, it also protects the concrete and easier to clean.

     When using a water base sealer, the concrete needs to be visually dry, any concrete stain residue needs to be thoroughly neutralized and rinsed well by mopping up or washing off and it needs to be free from dirt.

     Apply the sealer with a paint roller in 2 very thin and even coats. Do not apply in straight lines, but rather more like when painting, going back and forth and in different directions, overlapping and smoothing out.

       Do each coat in opposite directions. Example: Go North/South on the first coat and go East/West on the second coat. Avoid over applying as discoloration or cloudiness could occur. Will go on white and then dry clear.

        Allow to dry between coats until completely clear, including in any cracks, and no longer sticky. Usually about an hour or two in warm weather and low humidity. Minimum application temperature 45 F. Best application temps: 50 F - 90 F. Avoid applying in extreme heat or direct hot sunlight.

Clean up tools and spills with warm soapy water before it dries.

        Once it is completely clear, no longer sticky, and you can walk on it, Apply the second thin and even coat. You want the concrete to have an overall smooth and consistent look. If there are dry or patchy looking areas, additional coats can be done to smooth it out.

     The way the concrete looks after you have neutralized and rinsed it, while it is drying down, though still damp, is what it would look like if sealed with Clear Shield Decorative Concrete Water Base Sealers.

      You can apply using an airless sprayer, or spray on with a pump up sprayer and back roll any sprayer marks or heavy areas as you go. Do not allow to puddle. Though it's easier to just use a paint roller and roll it on.
