Levelling base
Leveling Base is a high-quality undercoat plaster specifically designed to create a smooth and even surface prior to the application of paints and decorative finishes that require a flawless substrate. What sets Leveling Base apart from standard products on the market is its unique, non-gypsum formulation.
Unlike gypsum-based plasters, our Leveling products do not shrink and do not carry the typical disadvantages of gypsum, such as vulnerability to moisture or mould growth. Instead, Leveling Base is alkaline in nature, giving it natural anti-mould properties and making it an excellent choice for healthy, long-lasting wall finishes.
Stucco Quartz primer trowel
Quartz Primer is a highly adhesive acrylic primer enriched with fine quartz sand, formulated as the standard undercoat for most of our lime and cement-based plasters. Its textured surface promotes excellent grip, ensuring optimal adhesion of subsequent plaster layers.

Thanks to its superior grip, it is also highly effective when applying plasters to wooden surfaces, such as tables, furniture, and cabinetry—ensuring durability even on more flexible or unstable substrates.
Designed for professionals who need maximum performance under demanding conditions.
TECHNICAL AUXILIARIES
Densifier for lime
Our Densifier is a specialized resin designed to increase the density and viscosity of lime-based plasters when mixed with alkaline materials. It is particularly useful when:
-
A large amount of liquid pigment has been added, making the plaster overly fluid
-
The plaster needs to be applied in thicker layers, helping prevent sagging or slipping during application
Ideal for improving workability in challenging conditions, the Densifier enhances control without compromising the finish.
Important: Exceeding the recommended dosage may reverse its effect, returning the mixture to a more liquid state.
SDA - Slow Drying Additive
Extended Working Time for Large Surface Applications
Our Retardant Paste is designed to extend the drying time of lime-based products, making it ideal for applications on larger surfaces that would otherwise dry too quickly. It can be used with all our lime and cement-based products, giving you more time to work without compromising the quality of your finish.
Application:
The quantity of Retardant Paste to be added depends on your specific needs, with the maximum recommended dosage being one full jar (0.9 kg) per 24 kg of material.
Packaging: Available in 0.9 kg buckets.
Cleaner for venetian plasters
It is designed to remove ordinary dirt, as well as dirt found above radiators or fireplaces. When you wash a wall finished with there is the risk that the dirt on the surface penetrates in the stucco together with the water you use to clean it, making it irreparably dirty. Our cleaner keeps the dirt into its foam, preventing it from penetrating.
