Great question dfitzge!
Welcome to the Community!
Faux finishes can range from slightly textured (paint and glaze) to roughly textured (Venetian Plaster or sheetrock mud).
Because your paint and glaze surface should be only slightly textured, your are going to need several basic paint tools: a good pole sander with 220-grit paper, a shop-vac to get up the sanding dust, and your paint kit including a 3/8 nap roller cover and drop cloth. In addition, your are going to use Behr Ultra (paint and primer in one) in the new color of your choice.
Compared to changing a roughly textured wall, your job will be relatively easy.
Begin by covering the area with drop clothes to catch the sanding dust. You may want to cover doorways to prevent the dust from "traveling." Also, plan to cover the HVAC registers and return vents to prevent circulating the dust around your home.
In some cases, lightly applied glaze may show no texture at all. In this case you can skip the sanding step (next).
Using the pole sander, lightly sand the entire surface to be painted. You are not trying to sand through the paint down to the wallboard. Rather, you are simply eliminating any raised surfaces where the glaze visibly shows ridges or texture above the surface of the paint. A light held at an angle to the wall will often show these spots, or you can use your hand to "feel" that the surface is smooth.
After you are satisfied that the surface does not show texture, remove the sanding dust using a terry towel to wipe the wall and your shop-vac to remove the dust from the baseboards and surrounding surfaces.
Apply your first coat of new paint and allow it to dry a minimum of four hours. Use the light or your hand to determine if any texture shows through this coat. If so, use the pole sander again to smooth the surface and remove the dust as before.
Apply your second coat of new paint and allow it to dry four hours, then look at the surface again.
Behr Ultra is a high-hide paint and usually does not require more than two coats to cover any other color, but you may have to follow the sanding-then-painting step one more time to ensure that the texture does not show.
Special Note: Lower sheens like flat or eggshell do not reflect as much light as satin or semi-gloss. The more light reflects, the more the imperfections on your wall are going to show ... so, even though this is a kitchen, think about using a flat (Ultra Flat is washable) or an eggshell on this project.
