Multiprim - water-based paint for aluminum, zinc, stainless steel, and copper.
The paint has very good adhesion to most smooth and compact materials, including aluminum, galvanized steel, stainless steel, zinc, copper (new and old patinated, oxidized), lead, black steel, hard PVC, glass fiber reinforced polyester, glass, and ceramics.
Multiprim is based on acrylic polymers. It has very good UV resistance and high durability in outdoor conditions.
It can be used as a primer applied in 1 or 2 coats. However, for long-term corrosion protection, Multiprim is best finished with Monoguard anti-corrosive paint or colorless Monoguard Clear.

More information about Multiprim aluminum paint.
The tables below show a comparison of the adhesion of Multiprim paint to aluminum and smooth substrates, and Monoguard anti-corrosive paint to aluminum, as well as copper (new and old patinated, oxidized), galvanized steel, and stainless steel.
Legend:
| ALUMINUM | ||
|---|---|---|
| Product | Substrate preparation | Adhesion |
| Multiprim | water + detergent | GT0 |
| diluted sulfuric acid + rinse with water | GT0 | |
| Monoguard | water + detergent | bad (adhesion is poor if we only clean and wash the substrate) |
| diluted sulfuric acid + rinse with water | GT1 | |
| Conclusion:
Multiprim gives much better results on aluminum than Monoguard. Acid preparation of the substrate is not 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. How to prepare aluminum before applying Monoguard paint?
NOTE:

| COPPER - NEW, IN GOOD CONDITION | ||
|---|---|---|
| Product | Substrate preparation | Adhesion |
| Multiprim | water + detergent | GT2 |
| 10% hydrochloric acid + rinse with water | GT0 | |
| Monoguard | water + detergent | GT2 |
| 10% hydrochloric acid + rinse with water | GT0 | |
| Conclusion: Multiprim and Monoguard give the same result on 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 the copper. However, we obviously recommend carrying out a test cleaning on a smaller area to confirm that the aesthetic effect will be satisfactory. |
||
| COPPER - OLD PATINATED, OXIDIZED | ||
|---|---|---|
| Product | Substrate preparation | Adhesion |
| Multiprim | water + detergent | GT0 |
| Monoguard | water + detergent | GT0 |
| Conclusion: Multiprim and Monoguard give the same result on old patinated, oxidized copper. Acidic substrate preparation is not required. We recommend using Monoguard paint because it has better anti-corrosion properties. | ||
Why does the can say that the paint is only 0.99 l, 0.97 l, or 0.93 l?
The total volume of paint consists of the volume of the base and the volume of the pigment.
The total volume depends on the color, but is very close to 1 l.
The exact volume of a 1 l package, depending on the color, is presented in the table on the right/below.
The volume of 5-liter packages varies accordingly.
