Painting Alumawood Patio Covers

Alumawood is a popular and durable material used for patio covers and awnings. Its aluminum construction makes it lightweight, low maintenance, and resistant to cracking, peeling, rotting, and warping. But even the factory-applied finish on Alumawood will fade and wear down over time from sun exposure and weather. Painting your Alumawood patio cover can give it a fresh new look and add lasting color.

Can You Paint Alumawood Patio Covers?

The short answer is yes, you can paint Alumawood patio covers. Painting aluminum is very doable with the right prep work, paints, and techniques. However, there are some important factors to keep in mind:

  • Use high quality 100% acrylic latex or oil-based enamel paints designed for metal surfaces. Stay away from cheaper vinyl and lower grade latex paints which won’t adhere well or last.
  • Proper surface prep is crucial – clean, degrease, and scuff the surface lightly before painting. This helps the paint bond.
  • Apply in thin, even coats allowing proper dry time between coats. Usually two coats is sufficient for adequate coverage and durability.
  • Hire a professional painter experienced with aluminum if you want the longest lasting, most durable painted finish.

While the baked-on finish Alumawood comes with from the factory is meant to stand up to sun and weather for years, paint can freshen up the look of an older Alumawood cover and allows you to easily change colors when desired. Just don’t go too crazy with frequent repainting every couple years or the paint may start peeling. Plan on repainting every 5-7 years, longer if possible.

Preparing Alumawood for Painting

Prepping an Alumawood cover properly before painting is the most important step for achieving great results. Here is a primer on how to get your Alumawood ready for paint:

Clean and Degrease

Use a general household cleaner or degreaser to thoroughly clean the Alumawood, removing any dirt, grease, oil or chalky residue from the existing finish. If there is mildew or mold present, use a mildew remover and a stiff brush to scrub it away. Rinse thoroughly.

Lightly Scuff the Surface

Using 120-150 grit sandpaper, lightly scuff the entire surface of the Alumawood cover. This helps the paint adhere properly. Don’t remove too much of the existing finish. Just rough it up a bit.

Remove Loose Paint and Dust

If you’re repainting an already painted cover, scrape off any loose or peeling paint. Feather surrounding edges smooth. Then wipe the entire surface with a tack cloth to remove dust.

Spot Prime Bare Aluminum

For any exposed bare aluminum, spot prime just those areas with a quality etching metal primer. This helps prevent corrosion under the new paint.

With proper prep work like this, you’ll have a clean surface ready for fresh paint that will look great for years.

Best Paints for Alumawood Covers

Not all paints are created equal when it comes to bonding and lasting on aluminum surfaces like Alumawood. To get the best looking, most durable painted finish, use these recommended paints:

Oil-Based Alkyd Enamel

Oil-based paints provide the toughest, longest-lasting finish on aluminum. For Alumawood covers, an exterior alkyd enamel, like Rust-Oleum Professional High Performance Protective Enamel, is an excellent choice. Oil paints adhere well, resist fading and wear, and expand and contract similarly to aluminum.

100% Acrylic Latex Paint

For a latex option, choose a high quality 100% acrylic latex paint formulated for metal surfaces, like Sherwin Williams ProClassic Exterior Alkyd Acrylic or Benjamin Moore DTM Acrylic Coating. These offer great adhesion and durability.

Krylon Fusion Spray Paint

For small Alumawood paint jobs, Krylon Fusion spray paint bonds incredibly well to metals and plastics. Just be sure to use their primer first for best adhesion. Multiple light coats work best for full coverage.

Avoid cheaper paints like vinyl, lower grade latex, and generic enamels. Stick with the premium quality paints designed for exterior metals and you’ll get great painted results on your Alumawood that will last.

How to Paint Alumawood Covers

Once your Alumawood cover is prepped properly and you’ve got the right paint selected, follow these tips for applying the paint:

Paint in Thin, Even Coats

Apply the paint in smooth, thin coats without allowing it to puddle or run. Thick coats take too long to dry and can crack. Multiple thin coats provide better adhesion and a smoother finish.

Allow Proper Dry Time Between Coats

Don’t rush the painting process. Follow the manufacturer’s recommendations for dry time between coats – usually at least 24 hours for oil-based and 4-6 hours for latex. This prevents trapped moisture problems.

Apply Two Coats for Best Durability

Most quality paints will provide adequate coverage in two coats. The second coat seals the first for added protection. Additional coats won’t improve durability much and can start showing brush marks.

Maintain Wet Edges When Brushing

While spraying paint on Alumawood is fastest, high quality brush painting works too. Maintain a wet edge as you paint and avoid going over areas as they start to dry or you’ll get lap marks.

Use a High Quality Brush or Roller

Spend a little more on premium brushes and microfiber rollers designed for smooth metal surfaces. Avoid foam rollers which flatten leaving texture. Quality tools make painting much easier.

Follow these tips as you apply the paint for professional looking results. Your freshly painted Alumawood cover will look amazing for years to come.

Painting Alumawood Cover Undersides

While the top of your Alumawood cover is the part most visible, for full protection you’ll also want to paint the underside surfaces. This isn’t quite as easy considering the height and angles involved. Here are some tips to make underside painting more manageable:

Use Ladders or Scaffolding

For one-story patio covers, an extension ladder with a work platform can allow you to reach much of the underside. For taller covers, renting scaffolding provides safe access.

Lay Down Drop Cloths

Protect the ground, outdoor furniture, plants, etc. from paint drips by laying down canvas drop cloths below the cover before starting.

Create a Raised Platform

Place plywood planks across sawhorses or ladders to create a raised platform. This allows you to stand comfortably underneath while painting rather than bending over.

Use Pole Paint Rollers

Attach rollers to extendable paint poles which allow reaching higher underside areas without climbing ladders. High quality microfiber or foam pole rollers work great.

With some creativity and the right tools, you can paint the underside of your Alumawood cover to get that freshly painted look everywhere.

Hiring a Professional Painter

While do-it-yourself painting is certainly possible with proper prep and technique, hiring professional painters who specialize in painting aluminum patio covers will provide the highest quality, longest lasting results.

Experienced With Aluminum

Professional painters with metal experience understand all the right products and processes for the most durable finish. DIY mistakes can lead to peeling or having to repaint sooner.

Proper Equipment

Painting contractors have the right ladders, lifts, and tools to safely access difficult areas like cover undersides. They can spray paint for a smooth uniform finish too.

Better Prep Work

Experts will take the time to clean, etch, sand, and prime the Alumawood properly so paint bonds incredibly well. This leads to longer lasting results.

Warranties Offered

Many professional painters offer warranties on their workmanship. This guarantees the paint job for a certain number of years.

While costing more upfront, hiring a reputable professional painter is worth it for Alumawood covers with a beautifully done paint job that will last.

Paint Color Choices for Alumawood Covers

Beyond getting the prep work and application right, choosing the right paint color is key to getting great results when painting your Alumawood patio cover.

Popular Paint Color Options

Some of the most popular color choices for aluminum patio covers and awnings include:

  • White – A crisp, classic color that complements most home exteriors
  • Beige – Warmer tan and brown beige tones blend well and hide dirt
  • Gray – Sophisticated grays from light silver to dark charcoal work on any style home
  • Brown – Rich browns like mocha and espresso provide an earthy feel
  • Cream – Softer whites like almond, ivory, and cream give a subtle elegance
  • Red – Vibrant reds and burgundies make a bold accent statement
  • Green – Nature-inspired greens like sage and forest add welcoming color
  • Blue – Cool tones like navy and sky blue are calming outdoor accents

Neutral vs. Bold Color Choices

Neutral white, beige, gray, and brown are the most common choices for aluminum patio covers since they seamlessly match most homes. But don’t be afraid to go bold with brighter accent colors as well. Vibrant reds, blues, greens, or other colors can liven up your outdoor space. Just be sure they complement your home’s existing color scheme.

Matching Your Home’s Exterior

Selecting a patio cover paint color that matches or complements your home’s exterior color palette helps it blend in naturally rather than clashing. Consider siding, brick, trim, shutters, and other exterior colors when choosing a paint shade. Soft whites, warm grays, tans, and other neutral earth tones tend to work on most houses.

Factors Affecting Perceived Color

Keep in mind that the color you see on a small paint sample can look different once applied to the larger surface area of a patio cover. Lighting also affects colors. Softer north facing light, shade, or artificial lighting at night changes how paint colors appear. Opt for medium depth colors that maintain their character in different lighting. Also, painted aluminum will show some sheen, subtly lightening colors.

Hiring a Color Consultant

If struggling to pick the perfect paint color for your patio cover, consider hiring a professional color consultant. Experts at firms like Color 911, Phorr Architects, and Color by Design can assess your home, analyze colors, and recommend shades guaranteed to complement your exterior beautifully. Their fees are well worth it for flawless results.

Painting Over Factory-Applied Finishes on Alumawood

Many Alumawood patio covers come pre-finished from the factory with durable baked-on finishes like Kynar 500 designed to last 15-20 years. But painting over these factory finishes is certainly possible for freshening up the look. Here are some tips:

  • For proper paint adhesion, thoroughly clean and scuff sand the existing finish first
  • Spot prime any exposed aluminum before applying finish coats everywhere
  • Satin or semi-gloss paints help hide imperfections in the existing finish best
  • Higher quality oil and 100% acrylic latex paints adhere well and last over factory finishes
  • Allow extra dry time between coats when painting over factory baked-on finishes

With the right prep work and paints, you can successfully apply a fresh painted finish over the factory coating on your Alumawood cover that will look amazing. Just don’t expect the paint to last quite as long as on raw Alumawood – plan on repainting after 5 years or so.

Avoiding Common Paint Problems on Alumawood Covers

Painting Alumawood covers brings amazing results when done right, but also comes with the risk of frustrating problems occurring if proper techniques aren’t followed. Be aware of these potential painting pitfalls:

With high quality application and paints, you can expect an Alumawood cover’s painted finish to last around:

  • 5-7 years for latex acrylic paint
  • 7-10 years for oil-based enamel

Plan on inspecting the paint yearly and touching up any problem spots. Then do a full repaint once fading and wear become extensive. With proper prep and painting techniques, your freshly painted Alumawood cover will continue looking amazing year after year.

Cost to Paint Alumawood Patio Covers

If hiring a professional contractor to paint your Alumawood patio cover, the costs typically range:

  • $300 to $800 for a smaller 8′ x 8′ pergola cover
  • $800 to $1500 for a 12′ x 12′ single-car cover
  • $1500 to $3000+ for a large 20′ x 20′ double car cover

Factors impacting the cost include:

  • The size of the cover – larger covers require more prep, paint, time, and equipment
  • Whether scaffolding/lift rental is needed to access high areas
  • If spray painting or just brush/roller application is used
  • How much repainting vs. painting over original finish is required
  • What prep work like stripping peeling paint or filling holes is needed
  • If you provide the paint or the contractor supplies it
  • Local labor costs and contractor rates in your area

While DIY painting can save on labor costs, hiring a pro experienced with aluminum finishes assures a long-lasting, high quality paint job.
