I use the ultra white on the tip, alternating from finger to finger, flash curing each one as I go. Then I do a final cure for two minutes. Next, without cleansing, I apply a coat of base, then sprinkle the powder, and proceed as normal. When applying the base directly over the white I tend to cover the pink first, and then gently float the gel over the white to the free edge. Hope that makes sense.... I got the directions from the website under the "pink and White" tutorials.
