ACB Group has developed special markings with high visibility for school environments As a producer, together with the government and other partners, we are committed to the safety of our children. The Topmark range improves safety in and around schools. With the Playmark range, we create fun in the playground. The pre-formed markings are easy to apply, weather-resistant and environment-friendly. Many schools have already appealed to our expertise. View the photos of a project at a school in Limburg here.
