These wallboards are salvaged from 18th and early 19th century homes. A wall board is what was used in homes before the use of modern studs. These boards were plastered over to make up an interior wall. The lime in the plaster left the marks visible on these boards. They can be removed by hard sanding. Light sanding gives shaddows of these marks which adds character to each board.
Prices vary, but base pricing starts at about $10 per linear foot. I prefer to price boards depending on quality however.
Must visit in person to pick out boards.
I can cut to size.
