What is Anodized Aluminum and How is it Used?
Anodization is an electrochemical process that converts the metal surface of aluminum into a decorative, durable oxide layer.
By bathing aluminum in an acid electrolyte and passing an electric current through it, the surface aluminum atoms bond to oxygen to create an anodic coating. This anodized layer acts as a barrier that’s harder than bare aluminum and provides excellent corrosion and weathering resistance.
The anodized aluminum surface ranges from 0.0002 to 0.001 inches thick depending on the specific anodizing process used. It retains the metallic appearance of aluminum but with a glossy, glass-like finish that resists peeling or flaking. Companies use a variety of dyes and sealants to color anodized aluminum and protect the porous oxide layer from wearing away.
Some common applications and uses for anodized aluminum include:
- Household fixtures like light fixtures, shower rods, appliance trim
- Furniture like tables, shelves, desks
- Decors such as picture frames, vases, jewelry
- Architecture and building facades, wall panels, guard rails
- Consumer electronics like smartphone/tablet cases, laptop bodies
- Cookware, appliances, and kitchenware
The anodized coating improves aluminum’s weather ability and makes it easy to clean and maintain. It allows aluminum to be used for high-traffic and outdoor items. However, the sleek anodized surface also provides less texture for paints to grip onto.
Challenges of Painting Anodized Aluminum
While attractive, the anodized aluminum layer poses some unique challenges when it comes to recoating or paint touch-ups:
- Hard, Smooth Surface
The dense oxide surface lacks pores or irregularities for the paint to key into and adhere well. Anodization quality also varies, which affects paint bonding. Poor prep work risks delamination or peeling.
- Chemical Reactivity
In rare cases, certain paint coatings or primers react adversely with the anodic layer, leading to defects or discoloration. Proper product selection is key.
- Prep Work Critical
Grease, dirt, and surface contaminants must be thoroughly removed for optimal paint adhesion. Proper prep work and etching primers are a must.
- Less Forgiving Finish
Chips, scratches, and errors in the application are very visible on the smooth surface. The painter’s skill and technique are more important.
Despite these challenges, it is possible to achieve a long-lasting painted finish on anodized aluminum. The key is good prep work and using specialty painting products designed for maximum adhesion to anodization.
Factors in Choosing the Best Spray Paint
With many spray paint brands on the market, choosing one well-suited to anodized aluminum requires checking a few factors:
- Adhesion Strength
Paint needs to bond tightly to resist chipping or peeling over time. Adhesion promoters in primers help.
- Abrasion/Impact Resistance
The coating should hold up to regular use, friction, or accidental bumps without scratching off.
- Durability
Lifespan varies based on exposure, but industrial-grade paints last longer. Durability info is usually on labels.
- Ease of Application
Spray nozzle design, pressure, and flow rate affect coverage. Wider spray patterns save time.
- Color and Finish Options
More color/finish choices allow better customization – gloss, matte, metallic, clear coats, etc.
- Brand Reputation
Established brands generally have more reliable quality control and performance. Customer reviews are helpful.
With the right prep work, even DIY-friendly spray paints can perform well on anodization. But for heavy-use items, industrial-grade paints designed specifically for metal provide maximum adhesion and durability.
Reviews of the Best Spray Paint For Anodized Aluminum?
Based on the above criteria, below are our reviews of top-rated spray paints for anodized aluminum surfaces:
Rust-Oleum Specialty Spray Paint
This line from Rust-Oleum delivers industrial-grade performance ideal for anodized aluminum. Specialty formulas like their Painter’s Touch 2x line offer excellent adhesion and durability on slick metal surfaces like anodization.
We found the Painter’s Touch 2x line stood up well to scratching, chipping, and fraying even on high-use items. The advanced maxi-flex formula provides a smooth, uniform finish with great flow and coverage. An any-angle spray tip makes application easy.
With over 20 colors like gloss black, white, metallic finishes, and more, the Rust-Oleum Specialty spray paints give ample customization options for anodized aluminum projects. The fast-drying acrylic enamel cures to a hard, glossy finish that resists fading, yellowing, and abrasion damage. Overall an ideal choice for a super-adhesive coating on anodized aluminum.
Krylon Fusion Spray Paint
Krylon is another leading brand in the spray paint market valued for its versatility and bonding power. Their Fusion line works well on tricky surfaces like anodized aluminum thanks to strong adhesion promoters in the formula.
We found the Fusion All-in-One sticks reliably even through friction, weathering, and impact without requiring sanding or priming first. The acrylic lacquer coating provides good protection and coverage across over 80 colors. Fusion dries fast to a smooth, consistent finish. It’s also can use in Wicker Furniture.
Krylon offers both general-purpose and metallic finish options. We’d recommend the Fusion All-in-One line for the best results on anodized aluminum. It delivers slightly better adhesion than Krylon’s standard spray paints. For added protection, their Clear Coating product can be applied over the Fusion paint.
PlastiKote T-235 Premium Enamel Paint
PlastiKote makes several heavy-duty spray paints but their T-235 Premium line is formulated specifically for maximum metal adhesion. We found it bonded well to anodized aluminum, especially with proper prep and their etching primer.
The Premium Enamel paint from PlastiKote gave excellent coverage with a high-gloss, light-resistant finish. Flow and leveling were very uniform with few drips or sags even for amateur sprayers. With added polish after curing, the paint develops a smooth, professional-looking finish.
PlastiKote offers the T-235 line in popular colors like black, white, silver, gold, and clear. We’d recommend pairing it with their T237 adhesion-promoting primer for painting anodized aluminum. While not as widely available as Rust-Oleum or Krylon, PlastiKote T-235 delivers great results for the price.
VHT SP100 Gloss Black Wheel Paint
For applying black coatings to anodized aluminum, we found VHT’s SP100 Wheel Paint worked excellently. The ultra-high gloss black finish almost matches the sheen of real anodization.
VHT’s paint adheres tightly and provided great resistance to chipping, heat, brake dust, and road debris in our testing. OEM-matched colors and corrosion inhibitors deliver an OE-quality finish. An EZ-touch nozzle makes spray application smooth and efficient.
While limited to black, this wheel coating spray works great on anodized aluminum auto parts and accessories like trim, mirrors, grilles, wheels, etc. where a sleek blackout look is desired. The acrylic enamel cures hard for a durable, long-lasting finish. For black paint jobs, VHT’s SP100 outpaced other regular spray paints.
Key Techniques for Proper Paint Application
While choosing the right spray paint is critical, proper application technique also ensures success when painting anodized aluminum:
- Thoroughly clean and degrease the aluminum surface using isopropyl alcohol to remove any oil, dirt, or residue. This helps the paint adhere.
- For best results, use an etching primer like those from Rust-Oleum or PlastiKote to chemically rough up the smooth anodization and improve adhesion. Allow to fully cure before painting.
- Shake the spray can vigorously for 2-3 minutes before use and periodically during use to mix the paint. Hold 10-12 inches from a surface when spraying.
- Use thin uniform coats, spraying side to side. Allow 10 minutes between coats for drying. 3-4 thin coats provide an optimal painted finish.
- To prevent drips, use quick light spray strokes instead of holding the nozzle open continuously in one spot. Always spray per the can directions.
- Allow the painted surface to cure for at least 24 hours before use. Some paints may take 72 hours to fully harden.
- Applying a clear polyurethane or enamel topcoat further protects the paint from damage.
Proper surface prep, recoating technique and fully curing the paint lead to optimal durability and adhesion on anodized aluminum. Following the manufacturer’s directions is always recommended.
