Real Faux Stone

finished This a real faux stone because it mimics cut stone and not just a textured surface, which is a common mistake when creating faux stone.  This may look ok, but it isn’t realistic.  Real, cut stone would be smooth to the touch but pitted (recesses).

To start, a tinted (off-white) primer was applied.

The texture coat consisted of a mixture of  SAT (Proceed smooth absorbent texture),  RRT (Proceed Rough Regular Texture), and a matte base coat for a chalky, texture.
Apply the texture with a domed glazing brush.

Sand with a 220 grit to flatten the peaks so it looks like it has pits and feels smooth to the touch.  Don’t over sand.  Dust.

Create an illusion of more pits by using a pointed brush with a transparent mix of RU, UB, and white for a cool grey.

Within the pits, add a darker tonality for the shadow on the top part.

  1. Hi, Thanks for sharing. Would you use tape for the grout lines if the job was really big? Or would you still do them by hand?
    Thanks, Christine
