What is Venetian Plaster?
When you’re doing a DIY project, it’s important that you know every little detail about the things that you’re using to get the project done. It’s important because, the more you learn, the better job you’ll do. Let’s get to know more about Venetian plaster.
Venetian plaster isn’t a modern art form. It’s been around since ancient times. Nowadays, it’s really popular. But, not everyone wants to have Venetian plaster on their walls. Some people like to keep it modern.
What exactly is Venetian plaster?
Basically, it’s a putty used for plastering walls. This putty is created with a mixture of fired limestone and water combined with lime plaster. Ultimately, what’s Venetian plaster, is lime plaster. They are both the same thing.
What happens when you use Venetian plaster or lime plaster on walls?
Most people who studied even a little bit of chemistry would know that carbon dioxide mixed with lime-water reacts to create calcium carbonate or limestone.
That’s why, when you plaster a wall with Venetian plaster or lime plaster, it’ll turn right back into limestone by reacting to the carbon dioxide in the air. This means that it begins as limestone and turns back into limestone if you use it on walls. It’s not magic; it’s just called science!
Venetian plaster or lime plaster has a depth of its own. It’s got a glass-smooth texture that looks astonishing. Colors like white, grey, black, beige, and brown look marvelous on a Venetian plastered wall.
The most fantastic thing about Venetian plaster or lime plaster is that it can stand the test of time even for as long as decades.
What really sets a Venetian plaster or lime plaster from other kinds of plaster is that Venetian plaster doesn’t have any aggregates to add texture and thickness to the appearance of a wall.
Whereas other plasters do contain aggregates like marble, glass, or granite. Other than that, some plasters look almost the same as Venetian plaster. But, they simply aren’t the same.

Step 1: Check Walls and Skim Coat Over Venetian Plaster
If your walls have been plastered with Venetian plaster for a long time, there might be some issues with the surface of your walls. And if you paint over any damaged parts on your walls, then you’ll end up with walls that won’t look good at all.
That’s why you need to check your walls properly and look for damages on the plaster. If you find any faults on the plaster, just skim coat over Venetian plaster where there are damages. Seal any tiny holes there might be on the surface of your walls. This will make sure that there won’t be any issues in the future.
All you have to do now is wait a bit so that the skim coat sets.
Step 2: Cleaning the Surface of Your Walls
There can be wax on the surface of your walls. You can’t put on primer or paint over this kind of waxed surface. What you need to do now is take the wax off completely.
To clean your walls, you’ll have to use mineral spirits. Dampen a lint-free cloth with mineral spirits and clean till there is no wax left on the surface of your walls.
Let your walls dry before you move onto the next step.
Step 3: Use an 80-grit Sandpaper
You’ll need to use your dust mask for this step so that you don’t end up inhaling the dust that comes off from sanding your walls.
Then, you start sanding your walls with 80-grit sandpaper. You can use both a palm sander or a drywall sander. Just make sure you take off all the stains that you didn’t get with mineral spirits.
To finish off this step, clean your walls with a wet cloth and wait till they dry.
Step 4: Use a 120-grit Sandpaper
When you’re done sanding with 80-grit sandpaper, start using 120-grit sandpaper and sand the entirety of your walls. Again, clean the surfaces with a wet cloth and let them dry.
Step 5: Use Masking Tape or Painter’s Tape
Some walls have nothing but flat surfaces all around. Whereas some walls have switch plates, electrical outlets, or even trim. You definitely don’t want to paint on those things. That’s why you need to use masking tape or painter’s tape on them to protect them from paint.
Step 6: Apply Primer
The most crucial part of painting a wall is applying a thin layer of primer so that paint adheres nicely to the surface of the wall.
It’s best if you applied a quartz or alkyd primer all around the painter’s tape with a brush for precision. Then, use a long-handled roller for the rest of the surface of the walls.
Step 7: Use Paint
Pour some latex paint onto your paint tray. Use a brush for working around the masking tape or painter’s tape. Switch to a paint roller or paint sprayer to paint the rest of the surfaces of the walls. Apply paint as instructed by the manufacturer.
Step 8: Removing Masking Tape or Painter’s Tape
Before paint starts to dry, you should take off the painter’s tape or masking tape, or it will pull off dried paint.
Step 9: Second Coat
Sometimes you need more than just one coat of paint for maximum effect. Although most primers give the paint enough support that you may not need another coat of paint, it still depends on what the manufacturer of the paint you’re using recommends.
Whatever the case is, remember that you should apply the second coat only when the first coat has dried thoroughly.
That’s how easy it can be to paint over Venetian plaster. Basically, all you need to do is sand, prime, and paint.
Even though it is a lot to do and the work is tedious, if you’re determined to do it yourself, there’s nothing that can stop you. Just follow these steps closely, and you’re good to go.
