COATING-
SYSTEMS

Our CleanTop® Coating system is much more than just a subsequently applied impregnation on the stone surface. Our Clean-Top® systems represent an essential competitive advantage for your products, and they are already approved for decades! From acrylate wet-side coating systems to 2-component systems (part of mixdesign and coating layer) to 3-component systems applied on the wet and dry side. The question is: What do you need for your products and for your market? Which benefits and climatic challenges are important for you?

With our advice and experience in application technology of spraying bars, roller systems and robots, we will find the right solution for your company to make your products more durable. You will achieve excellent results if we mutually consider the interaction of raw materials, surface properties and performance requirements.

We have been developing suitable coatings for a wide range of paving stones and slabs for over 20 years. In doing so, we are not only focussed on practice and customer value, but also benefit from our own experience in our production – day-to-day. As always, success is based on details.
