We applied a whitewash finish to an unfinished wood side table that was ordered online from International Concepts (OT-92 Lamp Table).
To create a homemade whitewash, mix one part water to one part flat latex paint. Wipe the whitewash mixture on the wood using a rag, similar to applying wood stain.
After the first coat is dry, sand the surface lightly with fine (220-grit or higher) sandpaper to smooth any raised grain. Then apply a second coat of whitewash, and allow it to dry.
