Gloss and Smoothness Specifications for Paint
Gloss and Smoothness Specifications for Paint
(OP)
How do I specify smoothness and gloss of a painted surface. Are there GLOSS numbers? What about smooth? Can I assume, because a surface has a certain gloss it must be smooth?
Thanks
Bill

For smoothness, you will need to consider multiple criteria. Roughness, waviness, lay, and DOI (distinctness of image) may be involved. There are multiple techniques, standards, instruments, etc. available.
You may need to contact some consultants, test labs, and vendors for help.

ASTM D523 describes a 100-scale gloss value, but requires an angle as well.
