Jotun Jotamastic Smart Pack HB Primer 10L

High Build Surface Tolerant Epoxy Mastic Primer for Corrosion Protection

Jotun Jotamastic Smart Pack HB is a two-component high build epoxy mastic primer designed for corrosion protection in demanding marine and industrial environments. Supplied in a convenient 10L smart pack, it simplifies mixing while maintaining the performance expected from Jotun’s Jotamastic range.

This surface tolerant epoxy is engineered to perform on steel substrates with less than ideal preparation, making it suitable for maintenance and repair work where abrasive blasting may not be achievable. It provides strong adhesion and builds a protective barrier to extend service life.

Jotamastic Smart Pack HB can be used as a primer or intermediate coat within a complete coating system and is suitable for use in atmospheric and immersed environments when specified.

Designed for professional use, it delivers consistent high build performance and reliable protection when applied in accordance with Jotun specifications.

Recommended Thinner

Jotun Jotamastic Smart Pack HB requires Jotun Thinner No.17 when thinning is necessary for application.

• Formulated for epoxy coating systems
• Ensures correct viscosity for spray, brush and roller application
• Maintains coating performance and film build
• Suitable for cleaning application equipment

Important: Always follow the Jotun technical data sheet for thinning ratios. Do not substitute with No.7 or No.10 thinners, as this may affect curing, adhesion and long term protection.
