Skim Coat Over The Venetian Plaster Surface First

Before you can paint over your plaster, make sure you check it for any defects and imperfections such as cracks, grease, and dust. If there are any, you need to get rid of them to ensure the surface is clean and ready for paint application.

The best way of getting rid of any dirt, dust, or grease is skim coating the surface. Skim coating will even help you seal the smallest holes!

Proceed With the Cleaning

After the surface is skim coated and you are sure there are no holes or cracks on it, cleaning is going to be your next step. For this purpose, you should use about ¼ cup of mineral spirits.

You will just need to dampen a lint-free cloth into the spirit and rub it against the wall or whatever surface you are working with gently. After cleaning, get rid of any remaining layer of dust. When you can see no dust on your surface, it means that you are ready for the next step!

Sand Your Surface With an 80-Grit Sandpaper

The next step is to sand the surface with 80-grit sandpaper. You can do it by attaching it to your palm sander to make the process easier to control. At this stage, you need to make sure you lightly sand all areas and corners on your wall or ceiling.

This will be especially handy if the mineral spirit you used before didn’t manage to remove much of the stains.

If this is the case, with the help of sanding, you will be able to get rid of them entirely. And of course, remember to wipe away all the sanding dust with a damp cloth to ensure better paint adhesion further.

Proceed Sanding With the 120-Grit Sandpaper

Most people often forget that using 80-grit sandpaper is good but it’s not enough to make the surface smoother and properly ready for painting. to make sure the surface is ideally prepared, you will also need to work on it with the 120-grit sandpaper afterward. In addition, using a finer sandpaper will help to create a good texture for the paint to adhere to.

Proceed With Priming the Surface

Applying a primer is another essential step in painting most surfaces, and Venetian plaster is not an exception. Just use a few inches of quartz or alkyd primer and use an edging brush to work around the painter’s tape to prime your surface.

Why would you need a painter’s tape?

Well, if you are going to paint the walls, there will surely be light switchers and electric inputs. Those have to be protected with the tape to not get painted over!

For applying a primer properly, we would suggest you use a long-handled roller to work on the entire wall. Besides, with a long handler, it will be easier for you to reach the most distant spots on the wall.

Also, when applying a primer, Emake sure you make the applicationin a thin and even coat. When you are done, allow the surface to dry according to the manufacturer’s instructions.

Apply the Paint

Finally, after your walls are cleaned and primed, you can start painting. You will need at least half of your paint tray for that purpose, as well as an edging brush for painting around the trim. For the rest of the wall, a long-handled roller will be just fine.

As for the paint, we’d recommend you opt for latex paint. Apply the paint according to the manufacturer’s recommendation and allow the surface to set and dry afterward. As an alternative option, you might want to use the HVLP paint sprayers since they evenly paint the surface with less pressure.

Add an Extra Coat of Paint If Needed

Sometimes, you might want to add another coat of paint to ensure better coverage. If you really decide to apply one more coat of paint, make sure you do it after the first one has properly dried! If you apply a new coat of paint over the previous one while it’s still wet, you will ruin the whole paint job you’ve done!

Inspect the Surface For Any Flaws And Imperfections

Now your Venetian plaster surface should look as desired after you have painted it. Nevertheless, don’t skip the final inspection! Check the surface for any imperfections and flaws. Those can include thin spots, missed unpainted areas, paint drips, or lumpy areas.

Should you find any, the flaws should be fixed. For example, thin spots and missed areas just need another layer of paint.

Should you find any drips and lumps, they will require more sanding and as a result, may create a new thin spot in the paint. If this happens, simply wipe away any dust and apply another layer of paint to the area.

This is how you should paint over Venetian plaster surfaces. As you can see, there is basically nothing difficult about the process. It’s just that you will have to prepare the surface a bit more finely and meticulously compared to the most of other painting projects.

Use a Paint Stripper to Strip the Wall

For this purpose, you will need a spray bottle filled with some paint stripper. We recommend you not just go for any stripper but instead, stick to the one that can only remove two layers of paint at most. See, if you use the wrong stripper, you will most likely end up with damaged plaster.

Begin by spraying a small area of your surface to test the effect of the stripper. remember that you are not supposed to start scrubbing the plaster immediately at this point! Afterward, if you see the stripper is working well, do the scrubbing gently, covering small patches at a time.

Remove the Wet Plaster

Now you can start removing the wet plaster with a spatula after you spray the wall with water as you move along. Even though this is the most tiresome part of the job, ensure it is carefully done in order to avoid creating deep gouges in the plaster or the drywall.

Smooth the Wall

After you remove all the Venetian plaster from the surface, remember to smooth it. You need to make sure that you repair any gouges or other imperfections before repainting! We recommend you fill over the surface or use a latex-based primer in the damaged areas.

After all the imperfections are fixed, smoothen the surface with a spatula to achieve an even finish. Then, allow the primer or the fill enough time to dry before you start sanding it down with a palm sander. In the end, finish your job by wiping off the dust that resulted from sanding.

What Is Venetian Plaster?

Thanks to this feature, Venetian plaster is very durable. Also, this kind of plaster is highly praised due to its specific feature: see, if you apply it correctly, it creates a marble-like finish with beautiful depth once polished.

Venetian plaster is very popular as a kind of plaster to use in areas that would be too expensive to fit with marble. You can find Venetian plaster on curved walls, intricate columns, and carved baseboards, for example.

What Paint Would Be Best to Use On Venetian Plaster?

When it comes to painting over Venetian plaster, people often don’t know what paint will work best of all on this kind of surface. And indeed, you should be aware of certain nuances regarding paint application! For example, since Venetian plaster is mostly limestone, regular vinyl and polymer-based paints will not properly adhere to it. Instead, we suggest you use latex paint like Rust-Oleum or something similar.

The simplest solution would be to buy an alkyd primer. This is a type of primer that adheres to the limestone exceptionally well. Besides, it will simultaneously create a surface that other types of paints can adhere to properly.

However, when using both primer and paint, you should keep the following in mind: these products will mask some of the luminosity and depth of Venetian plaster when used together. This is not necessarily a downside, but you should be aware of this nuance when deciding to paint over Venetian plaster.

Well, now you know that Venetian plaster can be painted over. More than that, you are aware of a proper painting procedure now which means you will be able to achieve a smooth and flawless coverage on your surface.

Also, we told you what Venetian plaster is and what specifics this material has. Like that, you can tell in advance how it may react to different application methods. Finally, you have learned what paint is best to be used over this kind of plaster.
