I'm trying to get the bottom 3 inches of a party plastered wall in the kitchen back to the bare brick as brick appear to be very damp - a dpc has been previously applied however at the time, the wall was fully plastered down to the floor with no gap. - this was done about 15 years ago. In the meantime, the kitchen was flooded about a year ago so not sure if the brick is damp due to flood or because of plastering to ground level.
Anyway, plaster is very hard to get off - any recommendations on any tools or applications to help and any other advice re re damp proofing? Might the lower bricks do with a silicon injection to dry out??
