Stucco Italiano substrates and additives for Venetian decorative materials

Be creative, mix and match your decorative finishes

Stucco Substrates and Additives

  • The unique feature of Stucco Italiano products is the large range of additives, combined with the range of standard materials. Some of these additives have been specially developed to solve problems that often occur working with materials and to assist in easing the application of decorative plasters. Other additives are designed to give special effects to lime and acrylic coatings or to give them the best protection.

Stucco Substrates and Preparations

Universal Primer

  • Universal Acrylic Primer is for preparing the substrate before painting or applying lime-based decorations. It must be diluted with water in a ratio of 1: 1 to 1: 9, and then applied with a brush, roller or pump on each type of substrate. It is also used as the first protective layer of flooring material, such as Pastellone, diluted 1:15 with water.
  • Coverage: smooth surfaces (i.e. gypsum substrates): 1L covers 20 to 60m²

Universal base coat for any type of substrate

It is suitable to protect Pastellone

Quartz Primer

  • This acrylic primer with quartz sand is characterized by excellent adhesion. It is used as a base before applying lime and decorative cement-based mortars. It is ready for use on any type of substrate, although 10% dilution with water is possible. We suggest using it especially on wooden or plaster substrates.
  • Coverage: 1L covers 12 to 16m²

GLP – Gap Leveling Plaster

  • It is a filler with extreme adhesion properties, which does not shrink out when it dries. Due to this quality, we use it to fill the gaps between tiles in the walls and floors, before applying Pastellone or other decorative plasters. Moreover, since it is very adhesive, it can be used as a first layer on very smooth surfaces, such as marble or tiles, before applying the product on a lime or cement floor. If our TGF is used, it is not necessary to sand the tiles; just clean the tiles to remove greasy substances before applying.
  • Because of all these qualities, we consider our GLP among the most useful additives for Venetian plaster and other stuccos.

  • Liscio is a natural, limestone mass used to level walls. It is applied in several layers over Universal or Quartz substrate. Due to its fine structure, the final surface is ideally smooth and is an excellent base for applying decorative thin-layer materials.

Special Accessories for Application

SAA – Strong Adhesive Additive

  • It is a powder that can be added to any decorative mortar based on lime or cement, in order to increase its adhesion to any surface, such as tiles and glass. The packages are 1kg and can be added to a 16kg bucket of Pastellone or 24kg of any decorative lime-based plaster.

Increases adhesion to any surface


  • It is a hardener for all our decorative mortars based on lime and cement. Our densifier is a special resin, which, once mixed with an alkaline mixture, gives a higher density and viscosity. It is used if the decorative plaster is too liquid, for example when a large amount of liquid pigment is added to the material. It can also be used when the decorative plaster must be applied in a thicker layer, to prevent it from falling off the wall during the application of the material. Keep in mind that if the suggested amount is exceeded (if you put more hardeners than necessary), the material will return to its liquid form.
  • Packaging: 50gr or 500gr can
  • Application: it must be slowly poured into the mortar while mixing with the mixer

FAQ for Stucco Italiano’s substrates and additives

  • We designed additives for Stucco & Marmorino to facilitate their application or help the applicator apply our mortars in extreme conditions. For example, in high heat, very large walls, crumbly or very smooth substrates such as marble or tiles. Furthermore, other additives for Venetian plasters and Italian stuccos are useful for solving the special requirements and wishes of our customers, when it is necessary to modify the material to make it brighter, more phosphorescent or with colored spots.
  • Stucco Italiano is a system intended primarily for artisans. Therefore, our stucco additives are used to give space for creativity and imagination of our customers. Most of them are decorative accessories for Venetian decorative material or other Italian stucco.
