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.

Hydrophobic agents

Exceed your customer´s quality expectations! Hydrophobic admixtures developed by METTEN for base and facemix fill pores and capillaries of your product, durably preventing water penetration. Added in the mixing process it becomes an integral part of the production. The result: significantly enhanced freeze-thaw resistence, reduced tendency toward efflorescence and much more!

Surface Protection

A coating or impregnation is the final step that completes the three level METTEN CleanTop® System – granting an easier-to-clean effect and significantly enhancing the long-term durability of your concrete pavers.

There is no one-size-fits-all solution. Every CleanTop® system is precisely tailored to your raw materials, surface finishes, and performance requirements. Backed by more than 25 years and more than 13.000.000 sqm of hands-on experience, METTEN offers you a comprehensive portfolio of proven solutions: From film-forming to non-film-forming coatings, from cost-efficient, high-performance wet side coatings to premium wet and/or dry side surface treatments – you and your customer can rely on consistent quality, lasting protection, and visible value.
