repairing cracks in walls

How do I fix cracks in walls? goto top

The most widely used method of fixing cracks in plaster or drywall is to "V" out the crack with a tool such as a can opener (the ones you use for tomato juice). This is assuming that the plaster/drywall is sound and still attached solidly.
Use a positive set compound such as USG's Durabond or Solid Product's Sudden Bond and a small trowel (margin trowel) or putty knife to force the mixed compound into the "V" created earlier. Note: Always follow the mixing instructions by the manufacturer for best results.
It is very difficult to exactly match the old plasters texture or a drywall texture, but some hints are: for a sand finish, some try to blend the repaired area in with a sand texture paint. For a smooth finish, please take your time while applying the compound. Some light sanding may be required if excess compound is used, and for a "textured" wall use your imagination (such as a small paint brush, a rag or stipple brush) to try to create the same texture as the original while the compound is still in a semi-cured state.
Prime the repaired area and repaint wall and blend the repaired area as best as possible.
