Our products

A product range which is future-orientated and highly competitive puts us among the world’s leading companies in the wood preservation industry. We offer a wide variety of products for timber and pressure impregnation. We also have solutions to protect against blue stain.

Vacuum pressure treatment

Modern wood preservation places high demands on research and technology. Today, preservatives must be effective and at the same time comply with the legal requirements for environmental, health and occupational safety. Wolman products offer you this security in all applications, whether with decking or structures that are subject to heavy loads such as wooden roller coasters. 

Wolmanit® CX or Wolsit® KD products. The right solution for every application.


Sinesto® and Wolsin® products provide wood with reliable protection against sapstain and other wood-staining fungi, such as mould. 

Treatment of constructional timber

Wolsit® EC products – the extensive Wolman product range meets all requirements for modern wood protection in building construction.

Protection of wood-based materials

Whether Wolsit® or Xyligen® - Wolman can provide optimum protection, whatever the demands on your wood-based materials.


One team. Many voices. Going Beyond, Together - this was the motto of the #SikaDay2024.
