If you are installing drywall to cover with a finishing plaster, there are some creative ways you can make the wall stand out in your home. One very popular (and simple) way to add that stylish touch is with a Venetian plaster. This technique is hundreds of years old and was created as a style to match the natural look of stone or marble without the cost and difficulty of using those materials. Venetian plaster is very common and readily available to apply over drywall or painted drywall very easily. Here is a basic guide on how to add a Venetian plaster finish to your drywall. (This is Part 2 of a 2 part series. To return to Part 1, click here.)

Step 1 – Prepare the Surface

If you are applying the plaster finish to a painted wall, it should be either a flat or satin paint. You will need to sand the wall with the 220 grit sandpaper on the block to remove the shine. Once you have the wall sanded down, wipe away the dust residue with a damp cloth to leave a clean surface. If you are applying the Venetian plaster to bare drywall, this step is not needed. It is recommended to use blue board drywall to best absorb the plaster finish.

Step 2 Apply the Plaster

Put on the rubber gloves that you have and open up the Venetian plaster. Use the stirring stick to mix the plaster completely so that it is all one uniform color. Use the trowel to begin applying the plaster to the way. To avoid additional marks or blemishes, you can sand the edges of the trowel so that it is rounded and less sharp at its points. Apply the plaster evenly and thin in random streaks covering a three foot by three foot square section of the wall. Leave some small areas bare without plaster as you go. Remember to wipe off the trowel periodically so the plaster does not dry and ruin the trowel. After the first complete coat is applied, allow a few hours for the plaster to dry completely.

Step 3 – Apply the 2nd Coat

Once the initial coat has dried you can apply the second coat. To do this, just apply some fresh plaster to the trowel and wipe it over the existing dried plaster. This new plaster should fill in any uneven sections or bare areas of the wall that were exposed. Once you have the entire wall covered in plaster, allow the second coat time to dry.

Step 4 – Extra Coats and Sanding

After the second coat has dried you can add additional coats if you want the wall to have a thicker surface. Once each layer has dried, use the 400 or 600 grit sandpaper to sand and polish the plaster surface. You can also add additional marks and designs by putting the flat surface of the trowel against the way and moving it in a circular motion. Afterwards you only need to apply the Venetian plaster protective coating and allow it to dry.
