Stucco Additives for Venetian plasters

Add a creative touch to your finishes

Stucco Additives

A unique feature of Stucco Italiano is its great range of marmorino additives and stucco additives, associated with its offer of plain materials. Some of these auxiliaries are developed to solve the problems that commonly occur to applicators and to facilitate the application of the plasters. Other supplements are conceived to add special effects to lime and acrylic finishes or to provide them with the best protection.

Stucco Additives for Substrate Preparation

Universal Primer

Universal acrylic primer to prepare the substrate before painting or applying lime-based plasters. It has to be diluted 1 to 9 with water, and then be applied with a roller on every type of substrate. It is also used as first protection layer of Flooring materials, such as Pastellone, diluted 1 to 15 with water.

Yield: Smooth surfaces (ex. gypsum substrates): 1 liter covers 20/22 m².

  • Universal Primer for any type of substrate
  • Used also for the protection of Pastellone

Quartz Primer

A very adhesive acrylic primer with quartz sand. It is used as an undercoat before applying lime or  cement-based plasters. It is ready to use on any kind of substrate, although a 10% dilution with water is possible.  We suggest to use it especially on wooden or gypsum substrates.

Yield: 1 liter covers 5/6 m²

  • Universal Primer for any kind of substrate

GLP – Gap Leveling Plaster

It is a plaster with an extreme adhesion capacity, that doesn’t shrink when it dries off. Because of this quality, we use it to fill gaps between tiles in walls and floors, before applying Pastellone or other plasters. Moreover, since it is very adherent, it can be used as the first layer on very smooth surfaces, such as marble or tile floors, before applying lime or cement-based flooring products. If our GLP is used, no sanding of the tiles is needed: just clean the tiles to remove the greasy substances before applying it. Because of all these qualities, we consider our GLP among the most useful additives for Venetian plaster and other stuccos.

FAQ on Stucco Italiano’s Stucco Additives

Why are so many stucco additives needed?

We designed our Stucco & Marmorino additives to facilitate the application or to help the applicator to apply our plasters in extreme conditions. For example, in excessive heat, very large walls, crumbly or very smooth substrates such as marble or tiles. Furthermore, other additives for Venetian plaster and Italian stuccos are useful to cope with particular requests from the end client, when the material needs to be modified to make it brighter, phosphorescent, or with colored dots.

I read that your stucco additives participate in the Stucco Italiano philosophy. What does it mean?

Stucco Italiano is a system designed primarily for the craftsman. Therefore, our Stucco additives are used to give space to the creativity and imagination of our primary customers. The majority of these are decorative additives for Venetian plaster or other Italian stuccos.
