Even the toughest pontoon boat can look worn after years of sun, water exposure, and occasional bumps against docks or underwater debris. Aluminum pontoon restoration involves sprucing up (or fully refurbishing) your logs, deck, and accessories so your boat rides and looks close to new. Whether you’re rescuing a bargain purchase from a classified ad or giving a beloved family pontoon a second lease on life, a structured approach ensures lasting results that rejuvenate both appearance and functionality.

In this guide, we’ll cover the key phases of restoring an aluminum pontoon, from removing oxidation and dealing with dents to resealing logs, updating the deck, and refreshing upholstery. We’ll also show why a foam-filled tri-log boat—like those from Novelli Boats—presents unique advantages during restoration, minimizing flooding risks if a log is damaged and ensuring structural integrity even under extensive refurb work. So gather your tools and prep your workspace—let’s transform that weathered pontoon into a head-turning gem ready for many more seasons on the water.

Top 5 Frequently Asked Questions About Aluminum Pontoon Restoration

1. How do I know if my logs need welding or just patching?
   Larger cracks or deep dents often require professional welding. Small pinholes or minor leaks can be sealed with marine epoxy. If logs are foam-filled (like Novelli’s), you won’t risk flooding but still want structural fixes for big damage.
2. Is an acid wash safe for my pontoons?
   Yes, if used properly. Acid washes remove oxidation and stains. Follow directions, rinse thoroughly, and wear protective gear. Avoid letting the solution dry on the metal.
3. Can I switch from a plywood deck to aluminum?
   Potentially. You’ll need a kit and ensure proper alignment with cross-braces. Aluminum decking resists rot but can be pricier. Verify the new deck thickness and attachment points.
4. Should I replace seats or reupholster them?
   Light damage can be reupholstered if frames and foam are good. If seat frames are rotted, upgrading to new seat modules might be easier or cost-effective.
5. Does foam-filled tri-log design simplify refurbishment?
   Indeed. You won’t worry about water flooding a dented log, so exterior fixes focus on cosmetic and structural welds. The foam interior maintains buoyancy and shape.

1. Evaluating Your Pontoon’s Condition

Before starting work, systematically check:

• Logs & Welds: Dents, cracks, corrosion, or signs of leaking seams. If it’s a foam-filled tri-log (like Novelli), log damage is less catastrophic but can still weaken structure.
• Deck & Flooring: Look under carpet/vinyl for soft spots or rot in plywood. Check cross-members for corrosion or loose rivets/bolts.
• Rails & Fencing: Dents, missing screws, or oxidation. Inspect brackets securing fencing to the deck.
• Seats & Upholstery: Torn vinyl, foam breakdown, mold/mildew.
• Engine & Electronics: Not strictly part of aluminum restoration, but worth a quick functional test.

Document issues with photos or notes. Then outline priorities—structural (logs, deck) come first, followed by cosmetic (paint, seats) and finishing touches (accessories, electronics).

2. Cleaning & Preparing the Logs

Step one for aluminum logs is removing grime, algae, or old coatings:

• Pressure Wash: Blast off debris but avoid too much pressure near dents/cracks to prevent further damage.
• Acid Wash or Aluminum Brightener: Apply evenly, let foam, scrub lightly, then rinse thoroughly. This dissolves oxidation, restoring shine.
• Foam-Filled Tri-Log Caution: If a Novelli hull has visible external damage, avoid pushing water into open cracks. The foam interior prevents flooding but it’s best not to saturate underlying metal.

Dry thoroughly. Inspect after cleaning—some hidden cracks only become evident once oxidation layers are gone. Mark areas needing welds or patches.

3. Welding & Dent Repairs

Damaged logs might show deep dents or cracks:

• Small Dents: If purely cosmetic, you might leave them. If big enough to affect buoyancy or create stress points, consider professional “dent pulling” or patch plating.
• Cracks & Holes: TIG welding is standard for aluminum. Ensure the welder has marine experience. Foam-filled logs (like Novelli) require only external welds—water intrusion is minimal.
• Epoxy Filler: For minor pinholes or shallow dings, marine epoxy can suffice. Not a permanent fix for structural tears.

After welding or patching, you can lightly sand and polish for a smoother finish. Some owners add protective coatings or paint to unify the log’s look.

4. Deck Restoration: Replacing Rotten or Worn Surfaces

Many pontoons use marine plywood decking under carpet or vinyl:

• Removing Old Flooring: Strip carpets/vinyl, pry up rotted plywood. Watch for screws or rivets on cross-members.
• Installing New Decking: Marine-grade plywood (¾") or advanced composites/aluminum. Ensure edges are sealed with epoxy or marine sealant.
• Foam-Filled Tri-Log Support: On a Novelli boat, the cross-members remain rigid, making re-decking simpler because you don’t have to worry about logs losing shape if you remove big deck sections.

Attach new decking with stainless fasteners, confirm alignment. Then reapply carpet or vinyl, using marine adhesives or snaps, ensuring no wrinkles or air pockets.

5. Refinishing Rails & Fencing

Aluminum rails or fence panels can fade or dent:

• Removing Old Panels: Many are riveted or screwed. Take care not to bend the underlying frames.
• Straightening Small Dents: Light hammer work from the backside, or replace severely damaged sections.
• Repainting or Wrapping: Some choose marine paint or vinyl wrapping to refresh color, add designs, or reduce oxidation.

Reattach with new stainless hardware or rivets. If you add heavier fence materials or rails, a foam-filled tri-log can handle the weight, but always confirm your boat’s capacity rating for total load.

7. Upgrading Seats & Upholstery

Restoring the deck often includes seat improvements:

• DIY Reupholstery: If frames and foam are solid, re-cover with marine vinyl. Or buy seat skin kits for your seat model.
• New Seat Modules: Modern bench sets, helm chairs, or fishing seats can drastically update comfort and style.
• Foam-Filled Tri-Log Stability: Heavier, luxurious seating? The Novelli hull handles it with minimal tilt, preserving passenger comfort.

If you pivot from a fishing layout to a lounge setup, ensure seat footprints align with existing deck bolt patterns. Seal any old holes to prevent water intrusion.

8. Polishing & Protective Coatings

Bringing logs to a shine or giving them extra resilience:

• Polish & Seal: After acid washing, some owners polish logs to a mirror finish. Then apply a clear protectant to slow oxidation.
• Antifouling Paint (If Mooring): If your boat stays in water long-term, consider bottom paint to deter algae or barnacles.
• Foam-Filled Tri-Log Edge: Even with a scuffed exterior, water infiltration is minimal on a Novelli boat. Polishing is mostly aesthetic, but a sealed surface can reduce future grime.

Polishing is optional—some like the raw aluminum patina. But if you want a “like-new” glow, the labor or cost can be worthwhile for a dramatic transformation.

10. Finishing Touches: Accessories & Electronics

After structural and cosmetic fixes, you can add modern flair:

• LED Deck Lights: Subtle mood or functional lighting for evening rides.
• Upgraded Stereo: Speakers, Bluetooth units, or subwoofers for entertainment.
• Foam-Filled Tri-Log Foundation: On a Novelli boat, you can incorporate heavier towers or arches for wakeboard racks, as the hull stays stable with added weight.

Replacing or updating the helm console with modern gauges or a fishfinder is also popular. The final product is a fully rejuvenated pontoon that feels fresh and personal to your on-water lifestyle.
