Jotamastic 85 vs 90: Which Epoxy Coating is Better for Steel Maintenance?
Jotamastic 85 is a smart solution for maintaining steel structures in corrosive environments like Bali, which often poses an endless challenge for property owners.
If we previously discussed the 3-layer system in the anti-corrosive paint Bali guide, now it is time to enter a specific realm: maintenance. In the world of industrial painting, the names Jotamastic 85 and Jotamastic 90 are often a point of debate for project owners.
Which is more efficient? Which is the toughest against salt spray? Both products are part of the Jotamastic family, which has been legendary for over 30 years in protecting the world’s most extreme assets. However, for your project in Bali, choosing the right specification is the key to cost efficiency.
Understanding the Concept of Surface Tolerant Epoxy with Jotamastic 85
Before comparing the two, you need to understand why this series is so popular. Both are types of surface tolerant epoxy. This means these paints are specifically designed to be applied to surfaces where perfect cleaning down to white metal is not possible.
In Bali, performing total sandblasting on existing structures such as operating hotel balconies is often difficult due to dust and noise constraints.
This is where the roles of Jotamastic 85 and 90 become lifesavers, as they possess extraordinary adhesion even on steel that has only been manually cleaned.
Deep Dive: The Advantages of Jotamastic 85 for Maintenance Efficiency
Jotamastic 85 is a highly suitable solution for routine maintenance. If your project is not located directly on a beachfront submerged in seawater, this product offers the perfect balance between protection and price. One technical point often sought by contractors is the ease of application. This product has a fairly long pot life, providing flexibility for field teams to apply it with a brush or roll in narrow areas.
Another major advantage is that this series is a tintable epoxy, meaning it can be tinted to a wide range of colors in the Jotun Multicolor Industry (MCI) system. This is perfect for maintenance projects that require specific aesthetic matching without sacrificing protection. Interestingly, for those concerned with environmental aspects, Jotamastic 85 is a green certificate epoxy with lower VOC levels, making it a healthier choice for crowded commercial areas.
One technical point often sought by contractors is the ease of application. This product has a fairly long pot life, providing flexibility for field teams to apply it with a brush or roll in narrow areas that are difficult to reach with spray machines.
When Do You Need the Performance of Jotamastic 90?
If Jotamastic 85 is the “workhorse” for general maintenance, then Jotamastic 90 is the “fortress” for more extreme conditions.
Jotamastic 90 has a higher volume solids content, which technically means the layer left after the paint dries will be thicker in a single application. Jotamastic 90 is usually chosen for areas requiring higher abrasion resistance or structures frequently subjected to physical impact.
In Bali, when compared to Jotamastic 85, the 90 series is more commonly applied to the underside of jetties, ship structures, or beachfront areas constantly exposed to sand abrasion and seawater.
It is also important to consider the drying time; Jotamastic 90 is designed for faster throughput, allowing for quicker recoating intervals which is vital for projects with tight schedules.
Jotamastic 85 vs 90: Which is Best for Your Bali Project?
Let’s break it down based on your project needs:
- Rust Resistance: Both are highly capable anti-rust paint for steel. However, Jotamastic 90 offers slightly superior protection in highly aggressive marine environments.
- Cost Efficiency: For routine maintenance of buildings, fences, or warehouse structures far from the shoreline, using Jotamastic 85 is far more budget-efficient without sacrificing Jotun’s protection standards.
- Project Speed & Drying Time: If you have very short downtime, the drying time of Jotamastic 90 is generally faster, especially with its wintergrade variant. However, for Bali’s tropical temperatures, the standard Jotamastic 85 version is already ideal and very manageable.
Why Choose Through an Official Jotun Authorized Dealer in Bali?
Choosing between these two technical specifications can be very confusing without proper guidance.
As an official Jotun Authorized Dealer in Bali, we often find cases where project owners use “over-spec” products, resulting in a wasted budget, or conversely “under-spec” products, causing paint failure within a year.
Buying from an official source ensures you receive certified authentic products, including access to technical support to calculate exactly how many liters of Jotamastic 85 you actually need to achieve a safe layer thickness.

In the end, there is no “better” product in an absolute sense; there is only the product that is “most suitable” for your needs. Use Jotamastic 85 for efficient, economical, and environmentally friendly maintenance solutions in general areas where a tintable epoxy is required for color flexibility. Use Jotamastic 90 if your project directly faces wave impact, heavy abrasion, or requires a faster drying time.
