Plastering over drywall is a technique used to achieve a smooth, durable, and aesthetically pleasing wall surface. This method combines the simplicity and ease of drywall with the classic finish of plaster, offering both structural and decorative benefits. To ensure successful plastering interior walls, it’s essential to understand the preparation process, the types of plaster used, application techniques, and the benefits and potential drawbacks.
Preparation Process

Any imperfections, such as nail holes, should be filled and sanded smooth. Next, apply a bonding agent or primer specifically designed for plaster. This ensures the plaster adheres correctly to the drywall. Some professionals recommend using a fiberglass mesh tape over the seams and joints of the drywall to prevent cracking in the plaster layer.
Types of Plaster
Several types of plaster can be used over drywall, each with its unique properties and advantages. Traditional lime plaster, known for its durability and breathability, is ideal for older homes or those seeking an authentic historical finish. Gypsum plaster, which is quicker to apply and dries faster, is more commonly used in modern construction. Venetian plaster, a high-end finish, offers a polished, marble-like appearance and is often used in luxury settings. Choosing the right plaster depends on the desired finish, application speed, and budget.
Application Techniques
Applying plaster over drywall involves several steps, typically beginning with a scratch coat, followed by one or more finish coats. The scratch coat, a thin layer of plaster, is applied directly over the bonding agent. It should be roughened slightly to provide a good key for subsequent layers. After the scratch coat has dried, the first finish coat is applied. This coat should be smooth and even, and it may require sanding once dry to achieve the desired texture. Additional finish coats can be added to enhance the smoothness and durability of the surface. It’s essential to work quickly and efficiently, as plaster can dry rapidly, especially in warmer conditions.
