Is there asbestos in horsehair plasterboard?

No. Horsehair was replaced as a strengthening additive in plaster by asbestos. Where one was used the other was not needed. However, the only way to know for certain whether asbestos was used in a plaster is to have a piece of it analyzed in a lab by a qualified technician.
