Add subtle dimension to your room with a diagonal line finish.

For Best Results:

Mix the entire quantity of glazing color needed for the project before you start painting. Combining the contents produces uniformity of color. This intermixing is called "boxing."

A dry whisk broom or almost any dry brush (4" or wider) will create a basic line effect. (The softer the brush, the less distinct the pattern will be). On smooth walls, a notched trowel or scarifier will create stronger, bolder patterns.

  1. Step 1

    Paint the base color and allow it to dry completely before glazing.

  2. Step 2

    To prepare your topcoat glaze color, pour 1 part BEHR ULTRA or PREMIUM PLUS® paint (one quart) and 4 parts FAUX GLAZE (one gallon) into a bucket and mix the contents thoroughly. For a more see-through or transparent look, add extra faux glaze to the mixture. For a denser or more opaque glaze color, add more paint to the mixture. The mixture will generally cover approximately 400 sq. ft.

  3. Step 3

    Dip a 2"-2½" wide nylon/polyester brush into the color glaze mixture from the bucket. With your brush, paint (cut in) around the perimeter of your working surface. Start at the top corner and continue along the ceiling and around the baseboards.

  4. Step 4

    Pour your color glaze mixture into a paint tray and work a 6" mini roller into the glaze until it is fully loaded. To remove excess glaze, roll the tool on the ribbed area of the paint tray.

  5. Step 5

    Starting at a top corner of your project area, roll the colored glaze down the length of the surface in a 3' wide vertical section.

  6. Step 6

    While the glaze is wet, drag a whisk broom over the section. Work diagonally from one side to the other (at a 45° angle).

  7. Step 7

    Continue to work in 3' wide vertical sections. Overlap and blend each section as you go to avoid hard edges.

  8. Step 8

    Repeat the process until the project is complete.
