Jotamastic 80 is a two pack, surface-tolerant, high solids, epoxy mastic coating for repair and maintenance. It is specially designed for areas where optimum surface preparation is not possible or desired, and as a solution for less severe environments.
Jotamastic 80 is an anticorrosive coating which can be used as primer, mid coat and finish coat or as single coat system in atmospheric and immersed
environments (aluminium versions for use below water). Can be applied at sub zero surface temperatures.
- Minimal surface preparation
- Can apply in low film thickness
- Low VOC - Good for the environment
- Good resistance to solvent & chemicals
- User friendly
- High solids product

Surface Preparation: All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.
Bare steel: Cleanliness: Power tool cleaning to min. St 2, mill scale free (ISO 8501-1:2007). Improved surface treatment (blast cleaning to Sa 21⁄2)will improve the performance. In case of hydrojetting the flash rust degree shall not exceed moderate in SSPC and NACE standards for water prepared surfaces.
Shop primed Steel: Clean, dry and undamaged approved shopprimer.
Coated Surfaces: Clean, dry and undamaged compatible primer. Contact us for more information. For maintenance UHPWJ to WJ2 (NACE No.5/SSPC-SP12) or Power tool cleaning to min. St 2 for rusted areas.
Other surfaces: The coating may be used on other substrates.
