How to apply multi-color concrete stain

Step 5: Applying the stain

After all the cutting in of the stain to the edges, using a pressurized spray canister,  the stain can now be applied. Before spraying, I pressurized the canister then using a bucket, adjusted the nozzle to a fine spray and removed any air that may have been in the spray wand. This is important, since you want a continuous fine spray without it sputtering or dripping. I also kept a rag on hand, so as the pressure diminished, I would lightly let off the handle and place the rag at the tip of the nozzle to prevent any dripping. Choose a corner to begin in and work your way backwards, to an exit point, so you don't have to walk on your freshly applied stain. To apply the stain, I kept the nozzle approximately 18 inches from the surface and moved the wand in a circular pattern, overlapping each circle to ensure consistent application. In order to prevent having to bleed the air out of the wand after a refill, be sure to refill the canister before all the stain is sprayed out. Once the first coat is applied to the entire surface, allow 1 hour to dry before applying the next coat. During the drying time, clean the spray canister by rinsing it with water, then placing the pressurizing handle back in, add pressure, then spray it into a bucket until it is only spraying clear water.
