How do you repair long crack in plaster?

Question

House is on hillside. Guess it is from settling. Have had it repaired professionally once and they put plaster in crack and smoothed. Two years later it is worse. I know this has to be doable. Tks.

You may plaster over the crack again only to find it crack yet again in a couple more years if the house continues to settle. Have you thought about just placing a mirror or some type of artwork over that area until you are sure that the settling is done? Whatever you decide — replaster or cover — hope this works out for you.

Using a power sander, sand vertically along the crack, extending 2” beyond each side. Remove enough material so that drywall mesh can be placed in and still be below the surface. After sanding, fill the area, top to bottom with drywall compound. Lay mesh in and smooth flat into wet compound. Smooth with trowel and let dry completely. Lighty sand and continue with another layer. Repeat this process until flush with wall. Once flush with wall, compound needs to be extended a few inches wider than the area so it can be feathered out.
