Quartz sand
If you are working on a beautiful model or a unique art project and need a finish that strongly resembles sandstone? Quartz sand is frequently used in this way, after mixing with polyester, epoxy and polyurethane resins, to obtain unique sand imitations.
This washed and dried silica sand is also often used in the processing of polyconcrete to obtain increased mechanical properties.
Moreover, quartz sand can be used for sanding. This way you increase the adhesion on, for example, tiles and you do not need to sand.
