Plaster Repair

Such a surface isn’t perfect, so it is also liable to damage. The following defects might appear on plaster walls and ceilings:

• Unevenness of the surface. Such a problem might occur only in the case of poor-quality work, for instance, if people decide to do it themselves or hire unqualified repairers. Experienced professionals are able to create a smooth and even surface.
• This defect might appear because of a very thick layer of plaster, incorrect preparation of a substrate, or because of the oiliness or dustiness of a substance. As a result, the substance will start separating from walls or ceilings.
• Such damages can occur for various reasons — for instance, due to the shrinkage of the foundation or seismic activity. Other causes might include rapid drying, movements in the material itself, or inappropriate preparation of the surface. When cracks are small, they are hard to identify, which makes it difficult to solve a problem at an early stage. The appearance of small cracks is known as crazing and can be detected by experts. Cracks might appear because of water damage or dampness.
• Rust stains. When applying plaster on a metal lath, a problem of rust trains might appear. It’s necessary to prepare the surface correctly and complete the work with plaster professionally to avoid or eliminate such a problem.
• Sometimes on walls and ceilings covered with plaster, certain whitish crystalline substances might appear. It happens due to the presence of unburnt salt in one of the plaster components. These salts absorb moisture and create white crystalline patches. It’s always vital to use high-quality materials when dealing with repairs.
• Such damage looks like swellings on the wall or ceiling surface. They might appear because of the late slaking of the lime particles in the material.
• If you see mortar joints, similar breaks, or other defects on the plaster surface, you have to deal with grinning. In this case, it’s better to apply an undercoat before using plaster. Experienced professionals know how to prevent and deal with this problem.
• Flaking & Peeling. Due to the absence of bonding or its low quality, small loose masses might be formed on the surface. In other cases, small parts can even come off the walls or ceilings.
• When there’re seeds, dead burnt lime, or other foreign bodies in the substrate. They lead to the formation of conical holes.

Various damages might appear as a result of temperature fluctuations, water leakages, vibrations from heavy traffic, excessive load, improper material/proportion, or normal aging of the surface. The timely actions are able to quickly return freshness and character to the old constructions and create a nice modern look while preventing more serious defects.
