Repair mortar DEC

The ready-to-use, extrudable joint mortar for the long-lasting closing of masonry joints

The fischer repairing mortar DEC is ideal for the lasting renovation of joints, the closing of cracks in masonry and the optical repairing of chips and breaks in façades and masonry. It can close drill holes that have burst, as well as downpipes, railings, lamps and cable connections. The practically odourless mortar can be easily processed thanks to its stable consistency. It offers really good resistance to weather, ageing and UV. Once a skin has formed, the fischer DEC is rainproof. fischer DEC is not suitable for permanent exposure to water.

Product Description

  • The ready-to-use, sprayable joint mortar means that there is no need to add water or carry out time-consuming pre-mixing work. It enables clean, purposeful work. This means that you avoid dirtying surrounding areas and wasting material.
  • Good adhesion even on slightly damp substrates practically allows for all-weather work and prevents forced interruptions.
  • The structure of the high-quality water-based polymer has been perfectly designed with the visual appearance of the mortar in mind. This ensures a discreet joint and perfect appearance.
