Abstract

In this work, the influence of surface roughness of a natural stone material on two important
parameters for the performance of the industrial coating process will be studied. The selected
parameters are contact liquid drop angle, to assess the best conditions for the application of the
liquid coatings, and the adhesion strength, to assess the best coating performance once the
coating has been applied and dried. These two parameters are quantitative and may allow the
comparison between different case studies. The study of influence will be addressed in this work
from a practical point of view, so that results can be applied in a current industrial process for
optimization purposes. The obtained conclusions are expected to be used to propose
recommendations for the stone industry to guarantee the performances of the coating systems
applied.
