Frequently bought together


Watco Roadmarker and Roadmarker Reflective is a versatile and quick drying line marking paint based on chlorinated rubber resin which can be applied as low as 5°C. It is showerproof in 1 hour and will accept pedestrian traffic in only 4 hours at 10°C. Both formulations can be used on bare concrete, asphalt or painted floors and may also be used on aged blacktop, thermoplastic coverings, and most types of painted lines and floor paints. 

For a more clearly visible marking we recommend Watco Roadmarker Reflective, which has a surface coated with fine glass beads. Light reflects from the back of each bead to give a brighter appearance. The glass beads are extremely hard wearing and also give the surface greater slip resistance. 


  • Ideal for private roads, car parks, industrial floors and school playgrounds.
  • Formulated to tolerate a slightly damp substrate
  • Based on chlorinated rubber
  • Apply with a roller or brush
  • Suitable for well ventilated internal or external floors.
  • Watco Roadmarker includes reflective glass beads for enhanced visibility

Surface preparation

Ensure surfaces are clean, dry and free from any loose material. Remove any contamination, including dirt, oil, laitance and light to medium grease with Watco Bio D, or for thick deposits of grease use Watco Concroff.


If appearance is critical we recommend the application of a small trial area first. No need to stir. Apply by roller or brush. Make sure the lid is not left off the product for any length of time to prevent it drying out.
