Domande Frequenti
What consumption should I use?
Consumption varies with technique: Venetian plaster 0.8–1.0 kg/m², textured plasters 1.5–3.0 kg/m², coarse stone-effect plasters up to 5 kg/m². Check the product datasheet.
How much waste is realistic?
10% is typical for smooth application; complex textures or inexperienced applicators should budget 15–20%.
Does this include primer?
No. Primer and finishing wax or top coat are sold separately and need their own calculation.
