I have a beam that is painted with a white paint; is there a technique to avoid sanding the beam and giving it a white appearance?
The technique of ceruse is applied to wood with pronounced veining (coniferous, in particular). It is not recommended on wood with tight pores (beech, cherry). In order for the white lead to look good, sand your beam "white", which means that there must not be a trace of paint to reveal the wood. To dig the veins, use a wire brush to scrape the surface gently and always in the same direction (in the wood grain). Pass a thin abrasive paper, dust off and apply your white lead. The finish can be done with varnish or wax. A SHEET on our site deals with the ceruse.
