How to Paint Over Venetian Plaster? A step-by-step guide

Venetian plaster is an attractive, textured wall finish made from a mix of marble dust, lime, and water. While it can provide a beautiful, unique look to a room, sometimes the color of the plaster may no longer match the existing decor.

When this happens, it’s time to repaint the walls. Painting over Venetian plaster may seem intimidating, but it can be a relatively easy DIY project with the right preparation and techniques.

Step 1: Prepare the surface

Before you begin painting, you must ensure the surface is clean and free of dust, dirt, and debris. Use a vacuum or a damp cloth to remove loose particles from the walls.

Step 2: Repair the surface

If there are any cracks, chips, or other imperfections, use a putty knife or a spackling compound to fill them in. Allow the putty or spackling to dry before you begin painting.

Step 3: Sand the surface

Using fine-grit sandpaper, lightly sand the surface of the plaster. This will help create a smoother texture for the paint to adhere to and provide a surface with more teeth for the paint to grip.

Sanding should be done lightly and with light pressure to avoid damaging the plaster. After sanding, use a damp cloth to remove excess dust and debris. This will ensure the surface is clean and free of particles interfering with the painting process.

Step 4: Apply the painter’s tape

Before you begin painting, it is vital to protect the edges of the plaster from the paint using painter’s tape. Applying the tape around the plaster’s edges will help ensure that the paint does not bleed onto the walls, which could potentially ruin the job.

Press the tape onto the wall firmly so it sticks securely. When applying the tape, check for any edges that may not be fully sealed. This will help ensure the paint job is done to the highest standard.

Step 5: Prime the surface

Now, prime the surface of the plaster. An appropriate primer will help the paint adhere to the surface and create a uniform finish. These are available in various finishes, and selecting one that suits the type of paint you will be using is essential.

When applying the primer, ensure that the entire surface of the plaster is covered, and it is best to use a brush or roller to achieve an even coating. Once the primer is dry, you can proceed to the next step.

Step 6: Apply the paint

When applying the paint, make sure to use the proper tools. Apply an even coat of paint to the surface of the plaster with a quality paintbrush or roller. For best results, make sure to follow the paint manufacturer’s instructions. Apply the paint in even strokes, letting it dry completely between coats.

Depending on the type of paint used, you may need to apply multiple coats to achieve the desired look. Allow the paint to cure completely before using the surface. For more tips on painting and plastering, consult a professional.

Step 7: Apply a topcoat

After the paint has dried, apply a topcoat of sealer to the walls. This will keep the paint from fading and give the walls a glossy finish.

Step 8: Remove the tape

Once the paint and sealer are fully dry, gently remove the painter’s tape from the walls—exercise caution when removing the tape to prevent any of the paint or sealer from being removed. To help with this, slowly peel back one corner of the tape.

Step 9: inspect the work and clean

When the painting is finished, inspect it to ensure it is even and free of streaks and drips. Wipe away any dust or dirt from the walls with a damp cloth.

What Should You Consider When You Paint Over Behr Venetian Plaster?

Considering a few things before painting over your Behr Venetian Plaster would be best. For starters, it is a porous material.

This means that paint will struggle to adhere to the surface and will likely chip and peel off over time. As a result, it’s critical to properly prepare the surface before applying any paint.

This includes sanding the surface with medium-grit sandpaper to provide a smooth surface for the paint to adhere to. Additionally, clean the surface with a specialized cleaner to remove any dirt or debris that could prevent the paint from bonding properly.

Once this is done, you can apply a single coat of primer to the surface before painting. This will ensure that the paint will adhere properly and last many years.
