FEATURES
Self-curing two-component system consisting of rubber base and hardener mixed by customer immediately before use.
APPLICATIONS
Construction and repair of the buildings and structures:
- Joints sealing of concrete and reinforced concrete structures with a maximum deformation of 25%
- Building structures junctions sealing
- Gaps and cracks sealing
Advantages
- The material is hydrophobic and provides hydrophobicity of the treated objects
- Mastic is resistant to the influence of atmospheric factors
- Mastic is resistant to the action of ozone and ultraviolet
- The material has good dielectric properties

THE MASTIC PREPARATION
Before application, thoroughly mix the mastic base with the hardener in the ratio 4 parts by weight of hardener for 100 parts by weight of base (or as indicated in the passport for batch of products). For mixing we recommend to use a slow speed drill with the mixer for viscous pastes.
WARNING! Pot life of mastic at 20°C is up to 1 hour.
COATING
Apply the mastic with a spatula, a syringe or other device. Mastic layer shall be at least 5 mm. The mastic should be applied evenly, without breaks, rolls and voids. Never use mastic in the rain and snow, if there is a risk of precipitation on the surfacemastic puts.
