Prepare for the job. Put a dropcloth down to catch any falling wall texture or drops of glaze. Put on a pair of latex gloves to protect your hands. Ventilate the room.
Paint the wall the primary color you would like to see through the glaze. Use a roller to apply a fresh coat of wall color. Remember that the color is going to be made more intense by the glazing process, so choose your shade accordingly. Allow the wall to dry for 24 hours.
Mix four parts glaze with one part paint. This color is going to be your secondary shade -- a color that complements your primary wall color. Roll out the glaze in a criss-cross pattern, covering 2 or 3 feet of wall space at a time. Wait two or three minutes as the glaze begins to dry on the wall.
Wipe off raised areas of glaze using a damp sponge. Within that three-minute time frame, gently begin to remove glaze from those areas, while leaving it in the recesses of the texture. The edges dry quickly, so wipe those areas first. Work your way into the middle of your glazed wall space, stopping occasionally to rinse your sponge and wring out the water.
Move on to the next section. Slowly work your way along the wall in 2-foot sections, repeating the steps of glazing, waiting and wiping. The work will look seamless if you begin each new section by re-glazing a few inches of the previous section. Clean your sponge frequently.
