How to use it
- Calculate length of juntas: 40m┬▓ ├À 0.30m ├ù 2 = 266.67 ml
- Calculate volume of junta: 266.67m × 0.003m × 0.01m = 0.008 m³
- Calculate weight: 0.008m³ × 1600 kg/m³ = 12.8 kg
- Apply factor waste: 12.8 kg × 1.15 = 14.72 kg of fragüe
Common mistakes
- ⚠️ Use frag├╝e incorrecto to The rate of junta (ep├│xico to zonas h├║medas)
- ⚠️ Not limpiar The exceso of frag├╝e antes of que seque
- ⚠️ Apply frag├╝e in juntas muy anchas without Use frag├╝e especial
Worked example
