    Why Etching Aluminum Is Important

    Aluminum is a notoriously tricky material to paint or coat. Getting a finish to stick usually requires sanding with coarse grit sandpaper until bright, then priming with a specialty primer. The Zinc Chromate primers commonly used in the past are expensive, and less widely available due to environmental concerns. Instead of painting, some choose to anodize aluminum. But if you want to prime and paint, you certainly can. And, you can get excellent results.

    The secret lies in etching the surface with the right product. Compare TotalBoat Aluminum Etch Wash to Alodine or Alumiprep 33. Our phosphoric acid-based etching wash is fast and easy to use, and creates the toothed surface required for epoxy primer or paint to bond successfully and durably.

Important Safety Information:

Phosphoric acid is dangerous to work with because it can cause serious skin burns, eye damage, and respiratory system damage. Do not breathe its spray, mist, fumes, gas, or vapors.

Always wear protective clothing and equipment to protect your eyes, skin, and lungs when working with TotalBoat Aluminum Boat Etch Wash. This personal protection includes gloves, glasses or goggles, a respirator, and a proper apron or similar protective clothing.
