Hi all, i have just completed a dpc on a wall in my house. i took the plaster off and injected the cream and left it for a week, the rising damp was pretty severe roughly about a foot and a hlf up the wall. When i put the base coat plaster on after the week i plastered over it 3 days later and wet patches are coming through! is this just a case of the trapped damp coming through and it should dry out? thanks for any advise Ian
