Progressive grit sanding – part 2

Let’s have a look at the effect of Sanding Grit vs Chatoyance: find out here what specific grit needs to be reached to boost grain depth.

A number of samples were progressively sanded to higher and higher grits and their chatoyance was measured at each step. The results are summarized in table below:

The same data are shown in chart below:

The chart clearly shows a sharp increase in chatoyance when going from 800-grit to 3000-grit for all the species.

Ziricote – 800-grit – PZC = 5.5

Ziricote – 3000-grit – PZC = 7.7

Black Walnut – 800-grit – PZC = 13.8

Black Walnut – 3000-grit – PZC = 24.7

Spanish Cedar – 800-grit – PZC = 12.2

Spanish Cedar – 3000-grit – PZC = 16.0

Euro Maple – 800-grit – PZC = 12.7

Euro Maple – 3000-grit – PZC = 16.1

Sweet Cherry – 800-grit – PZC = 8.2

Sweet Cherry – 3000-grit – PZC = 13.0

Staghorn Sumac – 800-grit – PZC = 14.8

Staghorn Sumac – 3000-grit – PZC = 27.1

Movingui – 800-grit – PZC = 12.2

Movingui – 3000-grit – PZC = 17.4

Black Locust – 800-grit – PZC = 13.3

Black Locust – 3000-grit – PZC = 20.6

QS London Plane – 800-grit – PZC = 10.4

QS London Plane – 3000-grit – PZC = 15.1

FS London Plane – 800-grit – PZC = 7.7

FS London Plane – 3000-grit – PZC = 10.3

Padouk – 800-grit – PZC = 14.5

Padouk – 3000-grit – PZC = 23.2

Sapele – 800-grit – PZC = 15.3

Sapele – 3000-grit – PZC = 21.0
