How to use it

  1. Calculate 10% waste: 20m² x 1.10 = 22m² of slabs
  2. Calculate stone volume: 20m² x 0.02m = 0.4m³
  3. Estimate weight: 0.4m³ x 2700 kg/m³ = 1080 kg (granite)
  4. Calculate adhesive: 20m² x 4 kg/m² = 80 kg of flexible adhesive

Common mistakes

  • ⚠️ Not sellar The mármol (es poroso and mancha fácilmente)
  • ⚠️ Use adhesive común in lugar of adhesive flexible to piedra
  • ⚠️ Not Verify que The estructura soporte The weight (piedra es muy pesada)
