Other Techniques for Applying Venetian Plaster Other Techniques for Applying Venetian Plaster
There are various methods to apply Venetian plaster. Venetian plaster requires very specific techniques so that it will properly stick to the wall. It is never a particularly simple job, but those who are familiar with basic DIY skills should be able to handle it.
Venetian plaster is a popular technique that has been used for a long time. It provides a smooth surface which gives an impression of depth and texture. The plaster mix is typically made from gypsum, limestone and sand. Sometimes, it is just made from gypsum and sand. By contrast, the traditional stucco is a mix of sand and limestone.
You can also tint the plaster with color. If you do this, you should add a water soluble coloring into the plaster before beginning.
Applying Venetian Plaster with a Trowel
Using a trowel to apply the plaster work is one of the most common methods. It does require care however. Holding the trowel at a five-degree angle, you can simply apply the Venetian plaster to the wall. This needs to be done as evenly as possible and this is where it gets difficult. You need to have a steady hand and a lot of patience. When the plaster is almost entirely dry, you can smooth it a little more easily using the trowel. You could also use some low grade sandpaper to get a smoother effect. It is very important that you only use the sandpaper when the plaster is already dry otherwise it will simply damage your work. Finally, add a thin finishing coat after cleaning the surface.
Applying Venetian Plaster with a Roller
Using the roller can easily get messy, but it can also get a job done quickly if your technique is good. To begin with, mix water with the plaster mix. Use one part of water to 2.5 parts of plaster. Stir the mixture until it is smooth and easy to apply. Dip the roller into the mix and simply roll it on to the wall. Apply a medium coat to start with. Before it is completely dry, you can then smooth the surface using a trowel as mentioned previously. Again, use the trowel at a five-degree angle and follow the steps above.
Sealing the Plaster
Sealing the plaster is an important part of the job. Fortunately, it is easier than the plastering itself. This will help to preserve the plasterwork and make it last a lot longer. You should use a water-based sealant to apply over the entire wall using a roller. You can also spray the sealant on to the wall if you have the appropriate equipment. When this is completely dry, you should apply a second coat for extra protection. The second coat should dry in a matter of minutes and any excess sealant should then be removed with a rag. This is important as it can otherwise leave white streaks of sealant on the plasterwork.
