After you added color and touched up any areas that need help you are ready to seal in the color using a water based floor sealer. We used the Stone Tone Sealer by Kemiko. You can use either a matte or gloss finish. The gloss of your floor will depend on what floor finish you use in the final step. The sealer is just to lock in the color.
We used a plastic paint tray and a lambs wool floor finish applicator to apply the sealer. You can also spray it on with a Wagner or comparable sprayer. If you use a sprayer just watch out for overspray.
It is important that the floors be very dry before the sealer is applied so that the sealer can soak into the cement and provide a good bond. Remember that this step is what will keep the color from being removed from the floor when the finish coat is scratched or worn through. The more that it can penetrate the cement the better.
To apply dip the applicator in the sealer and let it drip a little. Then coat the floor using even strokes being careful to avoid overlap lines or heavy spots that will be visible in the finished product. If you spray just watch out for puddling. In both cases be careful not to paint yourself into a corner. Also, follow the safety procedures outlined by the manufacturer. As with all the steps, keep the work area well ventilated.
Let the coat dry and you are done. If you wish to apply a second coat it will not hurt anything.
