My 125 year old house has old brick foundation which is exposed in the basement. I would like to plaster but don't want to do the complete three stage plaster job; the grout is deteriorated in many places and may be too fragile to attach wire lath. I have heard of a product that is a pre-mixed renovating plaster, but I don't know if such a product will work. Any suggestions?
This Old House's website advises getting a sample of the current plaster and mortar to s lab so you can get them accurately matched, if I remember correctly. They seemed to be saying that it was important that the brick and mortar be matched to each other, tho I'm not sure why..
