Caution: Always use a mask when working with metallic paints and powders, or spray paint. Getting Started:
Regardless of what is already on your walls, you can apply the joint compound over the surface without any additional preparation. Put some of the compound on your trowel. Scrape this all over the wall with a spatula,
smoothing it out. Try to keep the thickness of the joint compound consistent. While the compound is still wet, use an old baking tin to make "stone"
imprints along the wall. Starting about a 1/2" from the bottom of the wall in a corner, press the baking tin (baking surface side) firmly into the compound. Pull the tin off the wall, skip over 1/2", and press the tin into
the wall again. Continue until the whole surface is covered in rows of "stones". Clean off the spatula, then use the edge to indent the "grout lines" further.
Lean the spatula slightly into the middle of the stone to give it more definition. Then, leave the plaster to dry. Combine 1 part oil-based paint (in a sandstone yellow colour), 1 part glazing
liquid, and 1 part thinner. Mix well. Apply this coloured glaze all over the surface with a regular paint brush (no prior priming is necessary). Dip a rag into a bit of thinner, and rub the glaze all around. Leave the wall
to dry. Once the paint is dry, you can highlight the grout lines by painting them gray with an artist's brush. This finish is great for walls that are not in good condition, as it covers up
any cosmetic flaws like cracks or bumps. [main] [dry-brushed walls]
