A painting technique that homeowners are starting to use more is the faux Venetian plaster technique. This is a way of painting that uses a trowel and a thicker paint called Venetian plaster. It gives the wall a marble or stone-like appearance. As the light hits the surface of the plaster it gives off a very glassy, smooth appearance. Applying the faux Venetian plaster to a tile wall is very easy to do, but it does require some time and attention to detail.
Step 1 - Purchase Faux Venetian Plaster
Many paint stores will carry different colors of faux Venetian plaster. However, it is important to make sure that you purchase the right kind. When covering a tile wall you want something that has an adhesive within the paint to help it grip the surface of the tile
Step 2 - Clean Tile Surface
Before you get ready to apply the faux Venetian plaster to the tile wall it will need to be cleaned. Use a cleaning solution of warm water and simple detergent to get rid of any of the dirt and grime buildup. This is important for the plaster to adhere to the tile surface without the risk of falling off.
Step 3 - Prepare Surface
Since tile is very smooth, you will need to prepare the tile wall for receiving the faux Venetian plaster. Use a 120 grit sandpaper and use it to scuff up the surface of the tile. Do not try and remove any of the tiles. You are only looking to place small grooves within the tile for the plaster.
Step 4 - Set up Drop Cloth
Faux Venetian plaster can be quite messy if it gets onto surfaces where you do not want it. For this reason, make sure that you use tape along the corners and a drop cloth to protect floors and furniture.
Step 5 - Practice First
Since applying faux Venetian plaster is a technique that is not ordinarily done when painting, you will need to practice a little before putting it on your wall. Use a scrap of wood and use the trowel to spread it out in a thin application. Use the same application as you would if applying mud to the drywall.
Step 6 - Paint Wall
Once you have the technique down move to the wall and start to paint. Scoop up a little bit of the plaster with your trowel and spread it over the wall. Use random edges so that there isn't any pattern that shows through. Work in small areas at a time and overlap all of the edges.
Step 7 - Apply Second Coat
After the plaster has dried for about four to five hours, apply the second coat. Hold the trowel at a 90-degree angle to the wall so that you can fill in any low spots.
Step 8 - Apply Third Coat and Burnish
Apply the third coat and allow it to dry. Follow this coat with a burnish technique that will flatten the surface and give it a hard marble appearance. Hold the trowel flat against the wall and work it in a circular motion. The more that you do this, the smoother the surface.
