If the lines on your artificial surface are faded we can be fairly confident that these have been sprayed on. Only in very severe cases have inlaid lines faded as a result of UV instability due to a manufacturing issue. In the few cases of this nature it is normally the colour red that is more susceptible to this and due to improvements over time we have not seen a case of this for the last 10 years. The solution to sprayed lines fading is to to re-apply more aerosol or line marking compound. However, take care not to over-apply these paints, especially where lines overlap at the corners, as paint build-up can lead to slip hazards for users. If you find yourself constantly reapplying markings you might want to consider using our special 2 part compounds. These have been tried and tested over many years and some clients have experienced more than 18 months of useable life from a single application.
