Bartoline Etch Primer is an essential solution for metalworkers, DIY enthusiasts, and automotive restorers who need to ensure topcoat adhesion on difficult, non-porous surfaces. It excels at bonding to metals like aluminum, stainless steel, and galvanized steel, providing a durable matte foundation that prevents peeling or flaking. While it offers superior protective qualities for cars, tools, and machinery, users must be aware that it requires precise application conditions and a dedicated 24-hour drying period to reach full hardness.

No, this primer is specifically formulated for metallic surfaces and will not provide the correct adhesion or finish on porous materials like wood or plastic.
You should allow the primer to dry for at least 24 hours to ensure it has fully hardened before applying your chosen topcoat.
While it is designed to prime metal, its primary function is adhesion; for extreme rust prevention, ensure the base metal is fully treated before priming.
No, this primer is designed to provide a matte, durable base for your topcoat.
For best results, apply 2 to 3 thin coats, allowing 15-20 minutes between each application.
You are likely holding the can too close or spraying too heavily; increase the distance to 25cm and apply lighter coats.
Soak the nozzle in acetone or a dedicated paint thinner, then clear the aperture with a fine pin.
The surface was likely not cleaned thoroughly; strip the area and re-apply after degreasing with a solvent cleaner.
Before application, the metal must be completely clean, dry, and free of any grease or oil. Use a high-quality degreaser to prepare the surface, as any residue will inhibit the primer's ability to etch the metal. Work in a well-ventilated area, preferably between 15-25 degrees Celsius. After application, allow 15-20 minutes between coats for the solvents to flash off. Once finished, invert the can and spray for a few seconds to clear the nozzle, preventing clogs. Store in a cool, dry place away from direct sunlight.
