Most acrylic paints will have a glossy, satin/semi-gloss, or matte finish. Most walls will have a satin/semi-gloss or matte finish. If you use the same finish for both your wall and your design, you will get a more uniform result

Insert a roller cover onto a roller handle. Use a low-nap cover to result in a smooth wall texture, or use a thick-nap cover for a more heavily textured look. Dip the roller into the mud mixture. Roll the mud onto a piece of cardboard to test the consistency before you roll it onto the walls
