May be used wet or dry
Due to the continuous development of suction technology and grinding machines, wet grinding is increasingly becoming a niche application. However, wet sanding applications will always be an alternative solution for certain applications, and specifically clear coat rework. The 1948 siaflex series for both wet and dry applications caters to the different requirements and preferences of global markets and users. 

Dry application 
Machine sanding produces a finer surface finish than manual sanding. To achieve the same surface quality as in machine sanding, it is necessary to use one grit finer during manual sanding.
Wet sanding 
To achieve the same result with wet sanding as with dry application, it is necessary to sand with one to two grits finer.
