Primers can also help the plaster adhere better to substrates that may be more fragile or difficult to apply to, like a drywall surface. Primers help to create a good bond between the surface and the plaster, which can help make the finished project look smoother and more even. Yes, depending on the substrate and the area to be applied, Venetian plaster may need a primer. For a standard 12×12 room (144 square feet) in an average home, the cost of Venetian plaster typically ranges from $720 to $2,880. Labor costs for installation can add an additional $1 to $4 per square foot, depending on the complexity of the project. Generally, it can range from as low as $5 per square foot (for traditional, lime-based plaster applied with a trowel) to upwards of $20 or more for more specialized varieties using polymers. The cost of Venetian plaster varies depending on the size of the project, the type of plaster used, the cost of labor and other factors. How much does it cost to do Venetian plaster? You should ensure that the surface is clean and properly primed or sealed before applying the plaster. Regardless of the method of application that you choose, preparation is key. If you choose to use a roller, it should be a foam roller with a nap length of 1/4 inch or less. When using a roller, the end result won’t look as even and may lack the desired texture.Īdditionally, using a roller will require more coats and more time to complete the project. The thin and thick layers of plaster need to be applied with the trowel at different angle to each other to get the desired texturized effect. A special trowel is generally the most popular and recommended method of application for Venetian plaster. However, it is not the ideal application method and is not recommended. Yes, Venetian plaster can be applied with a roller. Can Venetian plaster be applied with a roller? Make sure to seal the plaster once it is complete. When the last layer is dry, use a trowel to refine the surface, then use a fine steel wool pad with a small amount of water to lightly work the surface and bring out the natural shine. Additionally, it is important to feather the edges so the transition between each coat is seamless. After that, apply the finishing layers, typically four thin coats are applied.īefore each coat dries, you will use a trowel to press and squeeze the plaster, achieving a flat surface with no undulations or grooves. Next, apply a scratch coat to the substrate by troweling on the thin mixture of Venetian polished plaster and let it dry before lightly sanding it. First, prepare the substrate and ensure that it is sound and dry. Applying Venetian polished plaster requires skill and experience, and it typically requires multiple layers of thin plaster, carefully applied in thin coats.
