Monoguard is a highly durable, water-based, quick-drying 2-in-1 anti-corrosion paint for direct application on rust, steel, zinc, and more, even in harsh industrial conditions.
Monoguard steel structure paint is based on a new generation of acrylic resins and special anti-corrosive substances. It creates a highly resistant protection for steel against temperature changes and external conditions. In addition, the paint is flexible, so it does not crack or peel. Thanks to its excellent UV resistance, the paint does not yellow and the colors fade very slowly.
Monoguard steel structure paint has excellent adhesion to many substrates, including:
Monoguard is ideal for general renovations as well as minor repair work. Before application, it requires only minimal substrate preparation (see application notes).

PROVEN EFFECTIVENESS
Monoguard can be used in harsh industrial and marine environments (C5). Its anti-corrosion effectiveness over a very long period (vH > 25 years) has been proven in tests conducted by the independent COT laboratory.
LONG-TERM PROTECTION
Monoguard anti-corrosion paint provides long-lasting (> 25 years) protection. Thanks to its very high adhesion and resistance to external conditions, it does not peel or flake off over time.
EXCELLENT ADHESION
Outstanding adhesion to various metals guarantees the effectiveness and versatility of the product. Thanks to its excellent adhesion, Monoguard anti-corrosion paint can be used both as a primer and a topcoat.
Durable corrosion protection - Certified in C5 environment
Outstanding adhesion - Effectiveness and versatility
Quick application - 1 day of work for 20 years of protection
Safe for people and the environment - low VOC content and PZH certification

After 1440 hours of salt spray testing, Monoguard anti-corrosion paint remains intact. Even around the incision, rust does not develop under the paint coating.
By applying 215 micrometers of Monoguard anti-corrosive paint (dry film thickness), we obtain one of the most durable anti-corrosive systems. The expected durability of the system is 15 to 25 years in industrial conditions.

Adhesion to ferrous metals:
Monoguard steel structure paint has excellent adhesion to ferrous metals - steel and cast iron (see COT tests for adhesion to steel - p. 4 and appendix p. 1 - 4).
Monoguard's adhesion increases over time. Weeks and months after application, the innovative components inside the coating continue to increase the bond, reaching up to 17 MPa / 2500 PSI when performing a pull-off test in accordance with ISO 4624 (substrate pull-off strength test). These values significantly exceed the 7 MPa / 1000 psi regularly required by many industry specifications.
Monoguard's excellent adhesion also actively contributes to protecting steel from corrosion. Because the coating adheres so well to the surface, it is more difficult for rust to begin its damaging expansion. The bond works so well that rust simply does not have enough strength to push the coating away and come into contact with the bare metal surface to which Monoguard has literally bonded itself.
This is also a big advantage in the event of local damage to the coating, as rust will not be able to spread easily.

Adhesion to non-ferrous metals:
For non-ferrous metals, Monoguard steel structure paint has excellent adhesion to galvanized steel, stainless steel, old patinated, and oxidized copper. For other metals, such as new copper or aluminum, special substrate preparation or the use of Multiprim paint for aluminum and smooth substrates may be required to achieve the best adhesion.
Detailed information is provided in the tables below.
Legend:
| ALUMINUM | ||
|---|---|---|
| Product | Substrate preparation | Adhesion |
| Monoguard | water + detergent | poor (adhesion is poor if we only clean and wash the substrate) |
| diluted sulfuric acid + rinse with water | GT1 | |
| Multiprim | water + detergent | GT0 |
| diluted sulfuric acid + rinse with water | GT0 | |
| Conclusion: Multiprim gives much better results than Monoguard on aluminum. No acid preparation of the substrate is required for Multiprim. Acid preparation of the substrate is required for Monoguard. For projects where aluminum is not exposed to mechanical stress, the adhesion of Monoguard to properly prepared aluminum may be sufficient. However, before applying it, we recommend testing it on a smaller area to confirm that Monoguard adheres well. |

| COPPER - NEW, IN GOOD CONDITION | ||
|---|---|---|
| Product | Substrate preparation | Adhesion |
| Monoguard | water + detergent | GT2 |
| 10% hydrochloric acid + rinse with water | GT0 | |
| Multiprim | water + detergent | GT2 |
| 10% hydrochloric acid + rinse with water | GT0 | |
| Conclusion: Monoguard and Multiprim give the same result on new copper. For best adhesion, it is useful to prepare the substrate with acid. During testing, cleaning with a 10% acid solution did not change the appearance of new copper. However, we obviously recommend conducting a test cleaning on a smaller area to confirm that the aesthetic effect will be satisfactory. |
||
| COPPER - OLD PATINATED, OXIDIZED | ||
|---|---|---|
| Product | Substrate preparation | Adhesion |
| Monoguard | water + detergent | GT0 |
| Multiprim | water + detergent | GT0 |
| Conclusion: Monoguard and Multiprim give the same result on galvanized steel. Acidic substrate preparation is not required. We recommend using Monoguard paint because it has better anti-corrosion properties. | ||
