Water-based faux finish and methods
Methods and compositions for applying a faux finish to a surface; as with a water-based base/primer to initially coat the surface with a base coat that is highly viscous and includes a relatively high percentage of solids that provide a three-dimensional coating having upwardly extending solids; the process may include applying a heavy coating of a second base coat, containing said solid particles, using a roller or sponge roller to provide raised areas (a multi-level surface); optionally applying one or more additional heavy base coats, in the same or different directions; optionally immediately flattening a portion of the surface of the base coat(s); rolling or spraying on a final coating of a glaze coat having a different color or tint than the base coat(s); and moving a portion of the glaze coat, preferably with a squeegee from higher areas to lower areas to visibly uncover a portion of the base coat, or to reveal a different shade of the base coat, due to a thinner glaze coat in higher areas where the glaze coat was moved, in a regular pattern.
1 . A kit for applying a faux finish on a surface comprising a base coating composition having a viscosity of at least 30,000 cp, as measured by a Brookfield Viscometer at 20 rpm using spindle #7, and a glaze coating composition having a viscosity of at least 10,000 cps, as measured by a Brookfield Viscometer at 20 rpm using spindle #7, wherein the base coating composition has a higher solids content than the glaze coating composition, and the base and glaze coating compositions include the following components:

7 . The kit of claim 1 , wherein the base coating composition and glaze coating composition each include TiO 2 pigment and each composition is colored white.
8 . The kit of claim 7 , wherein the base coating composition includes a colorant to color the base coating composition a first color, different from white, and the glaze coating composition includes a different colorant than the base coating composition, or a different percentage of the same colorant such that the colors of the base coating composition and the glaze coating composition are visually distinguishable.
9 . The kit of claim 1 , wherein the base coating composition includes a colorant to color the base coating composition a first color and the glaze coating composition includes a different colorant than the base coating composition, or a different percentage of the same colorant, such that the colors of the base coating composition and the glaze coating composition are visually distinguishable.
10 . A method of applying a decorative, faux finish onto a surface comprising:
(a) applying, via paint roller and/or spray, a base coat of an emulsified polymer-containing water-based base coating composition having 5 to 50% by weight of a solid filler having a particle size in the range of about 5 μm to about 100 μm; said base coating composition having a viscosity of at least 30,000 cps as measured on a Brookfield Viscometer at 20 rpm using spindle #7 and optionally applying, via paint roller, one or more additional layers of said base coating composition over said base coat;
(b) rolling or spraying on a final coating of a glaze coat from a glaze coating composition, having a different color or tint than the base coat(s), said glaze coating composition having a smaller percentage of solid filler than said base coating composition and having a viscosity of at least 10,000 cps, as measured on a Brookfield Viscometer at 20 rpm using spindle #7; and
(c) moving a portion of the glaze coating composition from higher areas of said base coat to lower areas of said base coat to visibly uncover a portion of the base coat, or to reveal a different shade of the base coat, due to a thinner glaze coating in higher areas where the glaze coat was moved.
11 . A method in accordance with claim 10 , further including the step of partially flattening upstanding solid particles in said base coat prior to applying the glaze coat.
12 . A method in accordance with claim 10 , further including applying multiple layers of said base coating composition prior to said final glaze coat.
13 . A method in accordance with claim 12 , wherein at least a portion of the base coating composition is applied using a paint roller that is rolled in different directions onto the surface.
14 . A method in accordance with claim 10 , wherein the glaze coating composition is moved from higher areas to lower areas of the base coat using a squeegee.
15 . A method in accordance with claim 14 , wherein the surface coated is a wall, and the glaze coating composition is moved from higher to lower areas of the base coat by scraping the glaze coating composition with a squeegee from an upper wall portion to a lower wall portion.
