Plaster and Lath


Definition: "Plaster and lath" is not only the two words plaster and lath, but combined defines a method of finishing interior walls that rarely is used anymore except to repair existing plaster and lath walls. Precedes the use of drywall as a means of covering up studs on the interior of a house.

First, a substrate in the form of a grid of lath is nailed perpendicular to the open house studs roughly a finger-width apart from each other. Then a thick layer of wet plaster is hand-troweled onto the lath and allowed to dry, before finish surfaces such as paint or wallpaper are applied.

Although few houses are built from scratch with the lath and plaster technique, countless houses remain with this type of building material. Homeowners can repair plaster walls by themselves quite easily. Also, companies which specialize in finishing drywall may be able to repair plaster walls, as well. Of course, urban areas that have a large quantity of older houses may have tradesmen who specialize only in plaster application and repairs.
