Plastering is a process used to cover uneven surfaces and rough walls with plaster material, which is a mixture of cement or lime concrete, sand and water. The plaster mixture is blended to the appropriate texture and then applied in several coats over the surface. The mixture is applied in layers in order for the mixture to dry in between coats and to ensure an equal smoothness to the surface. Repairing a plaster wall is required from time to time, especially as the building ages or following severe environmental occurrences, such as after an earthquake. Plastering companies in Los Angeles, including Stucco Experts Los Angeles are experienced in re-plastering damages, such as cracks, which help to prevent the need of rebuilding the wall.
common types of plastering problems
Plaster may experience cracking, especially if the material or the backing is aged. There are varying degrees of cracks as well as causes. For instance, hairline cracks are generally due to moisture evaporation, de-laminating cracks are caused by the plaster and the lath pulling away from each other and settlement cracks are the result of the building settlement. It is important to keep in mind that cracking and other damages to plaster must be repaired by a professional plastering contractor. If the repairs are not done correctly it may result in more extensive damages. Other types of plaster problems that require the assistance of plastering companies in Los Angeles may include:
- Blistering-This type of damage is typically caused when water is left in place behind the plaster. The water causes the lime, sand or salt to expand, which leads to blisters.
- Flaking-When flaking occurs; it is generally due to an improper or poor bond between the plaster and the lath behind it.
- Discoloration-Discolored plaster is common, especially in older buildings, but since it is caused by water seepage, it is essential that you contact a plastering contractor immediately to make repairs. The longer water remains in or behind the plaster, the worse the damages will be.
- Physical damage-There is a wide range of reasons why plaster may sustain physical damage, such as a collision, for example a vehicle hitting a wall or a natural disaster.
