Venetian Plaster is the best solution for having a damp protective wall. The versatile composition of this plaster involves construction materials like cement lime and sand.
But still there remains doubt in people that the wall won’t be getting any moisture and get deteriorated. To ensure that, people chose to plaster over that. But now the question is, can you paint over Venetian plaster?
Yes, you can ultimately paint over Venetian plaster after some preparation. Let’s know the necessary steps and combine them with your creativity.
Which Paints are Best for Using on Venetian Plaster?
You can’t start with any paint you want. Venetian gives an alkaline base that won’t create an adhering surface for polymer or vinyl-based paints. You should preferably go for Latex-based paint. Rust-Oleum is recommended one.
Another solution is to use an alkyd primer. You can do the job of priming the wall for adhering limestone as well as other paint types at the same time.
How to Paint Over Venetian Plaster?
Venetian gives a soft, earthy feel which brings elegance to your room. In case, you still want to paint over it, the followings are your indication:
- Masking Tape/ Painter’s Tape
- Paint container with brushes/ paint sprayer
- Denatured alcohol (mineral spirit as an alternative)
- 80 & 120-grit sandpaper
- Painting palate
- Palm sander
- Cleaning rag
So, these are the must-have necessities.
Step 01: Skimming the Plaster
Before you jump into the painting, look out for defects or residue over the plaster. You need to get rid of every defect before giving any new paint layer.
While many clean the wall by washing it off, the best solution is skimming off the defective coating. Such a decision of yours will fill the holes as well.
After you are done, wait for a few moments and let the wall dry.
Step 02: More Cleaning
In this step, you will be making sure that the wall is free from any unseen dust. Using a dampened rag, rub it against the wall. The rag needs to be dampened with denatured alcohol, not water.
Ensuring that the wall is clean now, and no particle will be hindering the process, let’s get to the next level.
Step 03: Sanding off the Plaster
Sand the wall with 80-grit sanding paper. Now there are two ways in doing that. One is to have enough manpower to sand the wall off. Another is to use a palm sander to do the work evenly and without much pressure.
Machine sanding would be effective here as it can balance the pressure and won’t get exhausted. That means sanding the wall in this step needs the minimum pressure.
Now, the question is, why we are performing this step? It’s not for everyone. The case could be after cleaning with rubbing alcohol, if there is a presence of any stain that couldn’t be removed with denatured alcohol, needs this step.
After you are done, now wipe off the wall using any dampened rag. This time you will be using water to dampen the rag.
Step 04: Another Round of Sanding
The previous sanding was responsible for cleaning off any hindering particles, like- grease, dust, stain, etc. But we did it using coarse sandpaper. Hence, the texture of the wall isn’t ready for painting.
This second round of sanding is for ensuring a smooth textured wall for painting. For this job, you will be using 120-grit sandpaper.
Step 05: Safety Precaution
Your wall has switchboards and electrical outlets. Use the painter’s tape to cover them up. It’s for safety reasons. Not only it will save the board from stain, but also from getting wet and malfunctioned.
Cover the floor as well with an old piece of cloth to save it from staining.
Step 06: Priming
Primer is the most common word when it comes to painting. Like any other case of paint, the primer will also play an important role here. Be sure to choose alkyd or quartz primer for Venetian paint.
Take a few drops of the primer into the paint try or the palate, then use the brushes to start your job.
The edging brush is basically for the edges around the masking tape. Use small brushes for detailing and fixation at the end. For the entire wall use roller having long-handled.
The length should not be too big. Choose the length that will be controllable for you for applying an even and thin coat. Then it’s time to dry the primer.
Step 07: Painting Time!!
Choose your color shades and fill your color try with a mixture of colors. Leave some portion of the tray to empty. It will be necessary in case of some mistake in the process.
Maybe you are using latex paint preferably. Start painting with the brushes required for each need. Paint in one direction to avoid agglomeration of the paint. In the end, you will get an evenly painted wall.
Now, let the paint dry according to the manufacturer’s instructions.
While you are using brushes and container paint, you might not know that spray paint will make this job even easier for you. You can alternatively choose HVLP spray paint.
Step 08: Removal of the Covering
Now you will be pulling out every tape you used in the project. A misconception is that you should pull the tape out after the paint is dry. That’s a pretty horrible idea.
Dry paints are quicker to come off. And so, you should be pulling the tape out when the paint is partially dried. That is, the paint is in adhering condition.
Step 09: Additional Layer of Coating
It’s an optional step for you. Choose to perform the step if your work needs it.
Many times, you might feel the necessity of applying another layer of paint. Apply it right after the former one is cured. However, it won’t be a good idea to apply a double layer of primer.
How to Remove Venetian Plaster?
Now that you are well aware of the steps, and suppose have decided to strip off the paint. What will be the procedure? Hoping that the following will give you a quick idea-
Use a spray bottle with having paint stripper in it, to spray over the wall. The stripper should not be able to remove more than the exposed outer paint layer or at most two layers.
After spraying the stripper, a spatula will be enough to scrape away the plaster. Wet plasters are easy to come off. After you are done, it’s time to smooth the exterior with sanding. At last, you will repaint it.
Right after you know, can you paint over Venetian plaster or not, I guess you are all warmed up to start the painting. Have fun and explore the painting over plaster.
However, when you are too energetic to start the job, don’t forget to take safety measures; especially if you have a breathing problem. It’s a must-do step, whether or not it’s mentioned in the procedure.
While painting over your Venetian plaster, you will notice the masking of its luminosity and depth. But it won’t be too much to notice. However, it’s not adding a negative point to the paint but its info that should be known.
You can paint over Venetian, as you want. However, the preparation work is a must for the paint to stay. Moreover, you need to be well aware of what kinds of paint will adhere to it.
Alkyd Primer is suitable for both Venetian plaster and all other paint types. So, why go for other primers, while this can be your all-time primer? Alkyd primer will not only adhere to limestone but also to the next paint layer you are providing also.
