Understanding your homes wall coverings is essential if you plan to
be an active member of your homes remodeling, repairs, and
decoration. You will need to know what your interior wall surface is
made of in order to make safe and effective decisions regarding
paint, wall treatments, and even when building an addition.
Plaster happens to be the most common form of interior wall surface.
Generally, plaster is a mixture of lime or gypsum with sand and
water. Once applied, it hardens into a smooth solid and is used to
cover walls and ceilings. It is popular for its flexibility and
knack for lessening noise. Plaster is commonly used to finish
interior wall work, generally over brick, stone or frame
Plasters durability can be compared with concrete. Both are made
from a mixture of dry compounds. A chemical reaction occurs when
water is added to this mixture. The ingredients begin a
crystallization process that eventually causes the plaster to become
solid. The result is a dense, hard surface.
It is important to watch out for plastered walls forming
stress-cracks. Harmless cracks will return with regularity no matter
how often you repair them. Definitely keep an eye open for loose or
crumbly cracks, holes, and bulges because these may mean you have a
leak. If you have a leak, fix it before doing any work on the walls.
Plaster repair can be a do-it-yourself project or handled by a
professional plasterer. Even older homes with more decorative
plastering can be repaired with the proper skills and tools.
In the past, plaster was applied to thin wood strips called lath
boards. Additional elements were often added to the plaster to make
it stronger. In more recent times, veneer plaster systems have been
introduced. Veneer plaster systems are similar to drywall, such as
being applied over special gypsum core boards and stimulating a
similar appearance to plaster. However, is it typically faster to
install, more durable, and exceedingly stronger.
