Stirrers for hot mastic

There are two ways to prepare mastics: hot and cold. Hot mastic is made on site several hours before use. The process requires careful control and safety measures. The most important qualities of hot roofing mastic are heat resistance, flexibility and adhesiveness.

It is the main water proof sealant for water proofing of all kinds. Mastics are also used for control joints. Hot mastics is a mix of oil bitumens or bitumen polymer blends with mineral filling. Bitumen roofing mastic is a black viscous substance, made of roofing bitumen with fibrous, combined or dust filling and an additive.

Bitumen mastic can protect any surface from moisture, mould or fungi. It does not bulge under influence of water vapor and creates a solid seamless waterproof cover. This material does not crack and is quite strong.


This material also serves for waterproofing of underground objects, such as sewer pipes, gas and oil lines, water pipes. It can be used for treatment of welding seams in metal structures and undersides of vehicles, contact lines between metal and concrete and brick in buildings, horizontal surfaces in pools and lavatories.

 Production process is rather hazardous due to the temperature of the materials. Depending on the type of bitumen, the temperature may vary from 110oC to 160oC, which is enough to cause burns or fires.

A good replacement is the bitumen based liquid rubber. It offers the same reliability and strength, while simplifying the production and application process. Liquid rubber is a bi-component bitumen-polymer emulsion; all words in the name are equally important: ‘bi-component’, ‘bitumen-polymer’ and ‘emulsion’. In classical sense, it is an emulsion of bitumen polymers, water and bitumen, with bitumen being the main substance. Production of liquid rubber requires special equipment to make emulsion stable to stratification, such stability being the main indication of the quality of the emulsion. We offer a specifically developed mixing device: GlobeCore™ CLM colloid mill.
