How to apply venetian plaster on walls: application step by step
Now that you have known exactly what venetian plaster is, where it can be used and what the most important characteristics are, you are probably wondering how to apply it on walls and ceilings.
In this section we explain the step-by-step process of applying venetian plaster on walls. Take note!
1. Make sure the walls are in good condition before applying venetian plaster
Check that the walls are in good condition: free of dust and without any irregularities, cracks or imperfections. In other words, completely smooth.
2. Mix the venetian plaster with the chosen dye
The next step is to mix the stucco paste with the chosen dye in a bucket and stir until the desired texture and colour is achieved, or you can buy a stucco paint, a ready-to-use paste already pigmented and ready to decorate the wall.
3. Apply first coat of venetian plaster
Now it is time to start decorating the wall or ceiling with venetian plaster. Apply the first coat of venetian plaster evenly with a trowel so that the surface is as smooth as possible.
When the wall is completely covered, leave to dry for at least 6 hours. After the time, use a spatula or sandpaper to smooth the surface and remove any remaining burrs.
4. Apply a second coat of venetian plaster
Apply a second coat of venetian plaster to the wall or ceiling following the same process as in the previous step. In this case, let it dry for 24 hours and use a cloth to wipe off the dust.
5. Apply the third coat of venetian plaster
Apply the third and final coat of venetian plaster. Unlike the previous two coats, do it in an irregular manner and purposely leave points of the wall or ceiling unfilled. Allow to dry for about 30 minutes.
6. Polishing to achieve the marble effect
The last step consists of applying a layer of wax to polish the wall or ceiling on which the venetian plaster decorative technique has been used. This wax leads to the marble effect that is the main characteristic of venetian plaster.
A wax that not only gives the surface a shine, but also protects the venetian plaster wall. The method of use of the wax is to apply it in a circular motion.
Venetian plaster price per square metre
The price of venetian plaster per square metre is between 80 and 100 euros.

Dimension of the wall where venetian plaster is to be applied
The square metres of the wall or ceiling are decisive for the price of venetian plaster. As a general rule, the applicator can offer a special rate for larger and more prominent surfaces in order to reduce the final cost.
Contracted labour for venetian plaster application
In relation to the previous variable, labour also influences the price. Each professional has specific application rates and uses a type of material that may be more or less expensive. Likewise, travelling can also increase the price per square metre.
Whether the future venetian plaster wall needs to be repaired
Although it is not a variable that depends on venetian plaster wall in itself, the price increases if the support on which this decorative technique is to be used is in poor condition. A substrate that will require conditioning and repair treatment prior to the application of the stucco. In some cases, the cost can be considerably higher.
How to repair damaged venetian plaster
If venetian plaster becomes damaged over time and cracks and fissures appear in the wall or ceiling, it will need to be repaired to prevent further deterioration of the surface. These problems can be compounded by a loss of colour over time.
Whatever the reason why the substrate has been affected, the repair is not simple and can only be carried out by an experienced professional. Below we will explain how to repair venetian plaster depending on the damage.

For small cracks or fissures in the wall or ceiling, use acrylic paint or putty to repair the substrate. Smooth and smooth the surface to make it homogeneous. Both the part that has been repaired and the part that has not, so that there are no visual contrasts. Then reapply the product as if you were applying the venetian plaster for the first time.
3. Cutter for larger cracks and holes in the venetian plaster
If, on the other hand, the cracks or fissures are larger and even a hole has been made in the surface, it will be necessary to use a chisel and mallet to remove the damaged area of venetian plaster wall. When there are no more imperfections, the product should be reapplied.
How to remove venetian plaster from walls
Are you bored of venetian plaster on your walls and don't know how to remove it? You have several alternatives to do it and apply a new decorative coating. Pay attention:

Microcement, the best substitute for venetian plaster for walls
Venetian plaster walls were, are and will continue to be a decorative trend. What if we told you that there is another decorative coating that offers the same finish as venetian plaster but cheaper and with more advantages?
This is the case of microcement on walls , a decorative stucco capable of providing the same texture as venetian plaster walls and which is also equally resistant to environmental humidity, impermeable to running water if a sealant is used and very durable.
In addition, microcement allows walls and ceilings to be renovated just as quickly as venetian plaster and without the need for building work or debris. Not to mention that it is resistant to sunlight (it can therefore be used outdoors), is cheaper and resists abrasion, wear and tear and friction. And best of all, as it is compatible with practically all types of materials (tiles, ceramics, tiles, cement, plaster, plasterboard...), it can be applied in many more rooms, thus considerably expanding the range of possibilities.
