Redecorating a room in the house. Removed the wall paper to reveal a crack in the plaster. I have opened the crack back to the existent wall and to find also a crack in this wall.... how do i go about fixing this crack before i go plastering???? Do i just fill it in with donding and then skim the wall or what... please help

Hi Jon,sounds like a fairly old house,theweakest points ,n houses are the window openings so any movement or shift inthe ground will create a crack, check to see there are no tree roots or heavy plants in the exterior area, if there are no other cracks or movement it may be safe to say its an old crack and can be repointed and then just replaster the wall

Yes the crack is on a external wall. Starts from under the middle of the window and runs down to the floor. Its about 2ft long and the width is about 1/8 of an inch, no wider than 3/16 of a inch. What i was thinking of doing is filling it in with bonding and leaving it shy 1/4 of an inch of the original plaster for skimming. Should be sound.... Right! What do u think d???
