Can colour markings be applied to rubber granules flooring?

Commercially available permanently flexible line-marking paints for synthetic sports surfaces and permanently flexible car park marking paints are suitable for PU-bound rubber-granule flooring.

Some rubber-granule slabs have porous surfaces on which lines may feather. Careful, clean application and precise masking are particularly important to prevent this.

Before application, a trial on slab offcuts is recommended to gain initial experience. Alternatively, a specialist sports-line-marking contractor can be used.
