However, if there are more significant cracks, an engineer may be required to analyze the problem, after which the area will be removed and replaced with new plaster. This is common in new homes and can usually be fixed by retaping joints. This can be because of foundation settlement, timber walls, masonry walls, and ceiling joists moving. Wall and ceiling plaster cracking might show after a few months of a new home being completed. Changes in temperature, the house’s expansion and contraction due to heat, changes in moisture content, foundation movement, and other factors all contribute to additional stresses.īelow, you will find eight reasons for your plaster cracks and ways you can remedy them. Corrosion, wear and tear, and a lack of maintenance, among other things, cause stress. You will also see cracks when the stresses exceed the permissible limits of stresses for a particular material-in this case, plaster. As a result, the material’s load-carrying capacity is reduced, resulting in cracks.
Natural disaster loads (earthquakes and cyclones)ĭue to poor workmanship or low-quality materials, some unknown or unexpected loads always occur.
Live load (the load of the occupants, furniture, etc.).Dead load (the structure’s load itself).There are three types of loads that can damage your plaster: All houses are designed to withstand various loads that may occur during their lifetime, but cracks may develop when there’s an excess of internal or external load.
