TO PAINT OVER NEWLY PLASTERED CRACKS IN WALLS.

When the painter has to paint over holes and cracks in walls recently filled by the plasterer, he will be likely to have to deal with plaster made in part of fresh lime. In such cases, it is always best to soak the newly plastered places with strong vinegar, to kill as much as possible the caustic properties of the lime. Put on the vinegar plentifully and let it soak in; when dry, give the new plaster a coat of size made of linseed oil, japan and turpentine; when dry, put on a coat of white shellac before painting.
