- Part A net weight : 15.3 kg - 1.3 kg = 14 kg

- Part B net weight : 7 kg - 1.3 kg = 5.7 kg

- PartA / Part B : 14 kg / 5.7 kg ---> 2.45

- Ratio by weight -> 2.45 : 1

Acceptable ratio range

- Standard -> 2.45 : 1 ( Part A : Part B as a ratio of total weight )

- Acceptable ratio range of Part A to Part B

2.32 : 1 ~ 2.56 : 1

Progress (1st coat + mesh installation ) - Spray on the primed surface -

A good fan makes the even surface and thickness A poor fan makes the irregular surface

( sagging,uneven surface )

- Trowel -

After trowelling,Mesh install with a proper mesh overlap ( 50 mm , 150 mm )

- Mesh installation and Rolling -

Makes the even surface and good wettability to substrate

e. Stipple coat ( if any )

Page 14: CHARTEK 7 Application Method - pds25.egloos.com

Progress ( 2nd coat ,stipple finish - if any ) - DFT check -

Before 2nd coat start, A DFT checking should be done at the 1st coated area

- Spray on the 1st coated surface -

A good fan makes the even surface and thickness A poor fan makes the irregular surface

Make the even surface and good wettability to substrate

( sagging,uneven surface )

- Trowelling -

Progress ( 2nd coat ,stipple finish - if any ) - Rolling -

- Stipple finish -

to give a wide fan and a coarse surface.

Make the flat surface with a big roller at the big area Make the flat surface with a small roller at corner,edge

Stipple coat is produced by boosting chartek material temperature and raising pump pressure
