Practice with Venetian plaster

It is very different from painting. Knowing how to paint a room does not automatically make you proficient with Venetian plasters. The professional is the painting contractor who has done plaster many times.

A Little time spends practicing with Venetian plaster tools that will help you gain confidence and skills.

A good way to practice is to buy a few sheets of drywall and then apply the plaster with a steel trowel using different strokes and different angles. 

Experiment by creating different amounts of texture on the surface. If you are adding your shade to the Venetian plasters, mix.

Small batches with varying amounts of dye (taking notes as you do) until you find the right mix.

Prepare your room for apply Venetian plaster


Clear the room as much as possible and spread a trap on the floor.

If there are any cracks or holes, fill it properly otherwise after the final Venetian plaster coating it will tear apart from that crack.

Wash off the dirt and grease. Surfaces should be primed or coated with paint.

Glossy paint surfaces can be covered with plaster as long as you lightly sand the wall/surface to remove the shine. 

Carefully read the instructions on the Venetian Plaster box for… NO more additional prep requirements.

Venetian plaster tools like steel trowels and drywall knives can have sharp angles that can leave marks and scratches in the plaster. To avoid this problem, round the corners with 100 grit sandpaper.

You can wear gloves when mixing and applying the cast, as this can irritate the skin. Protective goggles should also be worn if you extend it above your head.

Mix the Venetian plaster thoroughly before each use. 

First coating of Venetian plaster 

Open the box of Venetian plaster and, if necessary, add the tint. Mix all the ingredients well and make it think, not too liquid not too solid.

Start from the corner of the room. 

Apply the sealer with a flexible steel trowel (painting contractor also suggest 4 to 6-inch drywall knife).

Apply a thin layer of plaster; hold the steel trowel at a 15 to 30-degree angle. Distribute the plaster with varying lengths and angles of strokes.

Don’t worry about covering every square inch evenly.

Let some of the original plaster wall surfaces show through the stains, but keep the surface reasonably smooth sleek.

Clean the trowel from time to time to prevent the dried platter from getting into your Plaster finish.

Wait for it to dry completely (approximately four hours) before applying the next coat.

Second coating of Venetian plaster 


Use the same color of applying Venetian plaster for the second coat. Hold the steel trowel at a 60 to 90-degree angle, apply the plaster’s thin coat. Use long and short overlapping strokes (X-shaped). 

Carefully cover the surface, fill in any voids, and eliminate high areas.

Allow the plaster to dry for at least 24 hours before proceeding to the Venetian plaster finishing treatment.

Venetian plasters final finish touch

The final Venetian plaster step finish job involves burnishing the surface, and possibly applying Venetian plaster topcoat.

The top of coat Venetian plaster will add durability to the surface and is particularly recommended for rooms with high humidity (like bathrooms) and high traffic. 

However, if you do decide to use a topcoat, be sure to choose a product that is recommended by a professional’s painting contractor that is specifically recommended for the brand of plaster you used.

To polish, rub the surface with very fine sandpaper (400 or 600 grit) in a circular motion. Clean the surface with a damp cloth. 

The topcoat is usually applied with a trowel shortly after the plaster dries. The topcoat may darken the color a bit.

Once dry, you can polish the surface again with the flat side of a clean steel trowel or putty knife.

You can also create a good shine and add protection to the surface by using paste wax for the topcoat.

Apply a thin layer of wax with a trowel, and then polish the surface by rubbing it with the side of the trowel.

Useful recommendations

The choice of Venetian plaster is a matter of taste. It tends to resemble the texture of stone, pearls, surfaces covered with leather, wood, and fabric. If you wish, the texture can be corrected or even modified. The plaster walls or ceiling may become dull or shiny. Consider the purpose of the room, the style you want to change.

If you want to finish the metal with plaster, you will need to treat it with synthetic resins to prevent corrosion. Over time, it will become partially visible even through the translucent plaster layer.

The final wax coating is necessary to ensure moisture resistance. It is used in bathrooms, bathrooms, or kitchens after the Venetian plaster is finished.

The only caveat here – keep in mind that wax tends to darken over time, so avoid too much.

If successful, you will have a beautiful textured, moisture resistant, hard, and smooth sleek surface; plaster can serve you up to 15 years or more.

Another advantage is the ease of selecting the desired color and texture for your furniture.
