Input (English): [header] How to grey wash wood [title] Lay down a tarp or dropcloth. [step] Choose a well-ventilated area to work in, and set down something to protect your floor. Newspaper is fine if the object is fairly small, but a tarp or large dropcloth will work better if it's a piece of furniture. <sep> (A) [title] Sand the wood to remove paint and imperfections. [step] Use a coarse sandpaper all over the surface of the wood you plan to apply the wash to. (B) [substeps] You don't have to make the surface completely white. Just make it some at least small enough to keep paint and dust from piling up under the piece of furniture. (C) Wearing gloves and a mask to protect yourself will also help prevent the grey cloth from dripping onto the floor. [substeps] Some people may also do a lab experiment to change the paint prior to using the cleaner. (D) If you work outside, always wear gloves and respirator. [substeps] Stand straight up with your hands planted on your hips or standing with a slightly bent back.
