Introduction
Italian plaster is a decorative coating based on lime paste and marble powder, applied in multiple layers and achieving high gloss when polished. It breathes thanks to its natural structure; however, protective sealer/wax is essential for wet areas.
Who Is It Suitable For?
- Living rooms, entrances and corridors seeking feature wall.
- High visual impact in prestige spaces like hotels/villas.
- Surfaces requiring protection with proper sealer in areas like kitchen and behind sink.
Material Selection
Product family is usually divided into Marmorino Fine/Coarse and Grassello di Calce. Granule size determines texture and final gloss. UV-resistant minerals should be preferred in pigment selection.
Application Steps
- Surface Preparation: Flat, solid, dust-free base; appropriate primer.
- 1st Coat (Base): Thin and homogeneous spread with steel/stainless steel trowel.
- 2nd Coat: Coverage with cross movements; surface corrections after partial drying.
- Burnishing (Polishing): Increasing gloss with correct trowel angle and pressure.
- Protection: Natural wax or water-based sealer according to area requirements.
Common Mistakes
- Insufficient surface flatness → wavy gloss.
- Wrong trowel angle → burn marks/darkening.
- Skipping sealer in wet areas → stains and water marks.
