Plaster and Hemp

Intonaco e Canapa is a special plaster based on NHL 5 natural hydraulic lime and 0-6mm Fine Canapulo, designed for the breathable protection, restoration, and conservative restoration of even heterogeneous masonry made of hemp and lime Biomattone®, brick, tuff rock, and natural stone. A specific formulation with high permeability to water vapor diffusion, it is intended for filling, roughcasting, base plaster, and rustic finishing of new or existing masonry, both internal and external. Due to its natural properties and color, it is particularly suitable for work on buildings of historical and artistic interest or for environmentally friendly green building projects.

Substrates to be plastered must be stable, clean, and consistent, free of loose particles, dust, bacterial growth, salt efflorescence, oils, greases, waxes, residues from previous work processes, etc.
If necessary, pre-clean the substrate by pressure washing or sandblasting. The product can be mixed manually with a low-speed electric mixer or applied mechanically using plastering machines for premixed products.

Mixing and installation

For manual applications, mix Intonaco e Canapa by adding 6-6.5 liters of clean water per 25 kg bag in a cement mixer. Pour the correct amount of water into the cement mixer, then add the powdered product. Mix the product for approximately 2-3 minutes until a smooth, lump-free mixture is obtained. Apply the product with a trowel like a traditional plaster. The mixed product can be used within 2 hours of mixing with water. Corner guards, separation strips, level guides, etc. must be installed before applying the plaster layer to the entire wall. For mechanical spraying applications, apply the product evenly in a single layer, with a thickness of between 10 and 20 mm. Subsequent layers can be applied as long as the previous layer is not completely dry. The plaster is then leveled and finished using an aluminum straight edge. Any burrs or excess material are removed by scraping and polishing the surfaces.

The surfaces thus prepared are ready for finishing products: to achieve a fine, natural finish, use Malta Fine indoors and Stabilitura Naturale Traspirante Plus outdoors; to achieve a textured finish, use Canapulino or Canaposo.
