Preparing Your Boat for an AWL-GRIP Repaint: Owner Checklist

Pre-drop-off checklist to avoid delays and warranty issues

A full AWL‑GRIP repaint is a significant investment. Small prep steps on your part save time, money, and headaches.

According to AWL‑GRIP guidance, AWL‑GRIP is a professional two‑component polyester urethane topcoat.

It is formulated for above‑waterline use on fiberglass, aluminum, steel, and wood, and it is much tougher and more UV resistant than factory gelcoat.

Boat owners choose a full AWL‑GRIP repaint when widespread oxidation, cracking, or color inconsistency make spot gelcoat fixes impractical. This checklist shows what you must do before drop‑off. It will help protect systems, speed work, and avoid surprises that delay the job or affect warranties.

Learn why working with a certified AWL‑GRIP paint center matters: what certification means for your warranty and finish.

What we inspect first and which repairs must be done before paint

Worried about hidden damage under old paint? We start with a full, documented pre‑paint inspection so nothing surprises you later.

According to AWL‑GRIP guidance, that inspection must identify structural cracks, delamination, soft spots, corrosion, blistering, and the condition of existing coatings down to the substrate.

• Check for structural cracks and deep gouges, which require grinding and proper fiberglass repair before fairing.
• Locate delaminated areas and soft spots that indicate core failure or trapped moisture.
• Inspect for corrosion and osmotic blistering, especially on metal or wet core areas.
• Evaluate old fairing and filler for shrinkage or voids that will telegraph through a high‑gloss finish.
• Test previous coatings for compatibility so we know if removal is required down to the substrate.

Which structural repairs we always finish first

Transoms, stringers, core rot, and delamination are critical repairs that must be completed and cured before any cosmetic AWL‑GRIP work.

We repair cores with epoxy, re‑glass weakened areas, and refair surfaces so the new paint adheres to a stable substrate.

How surprises are prioritized and what to budget

We prioritize work that affects safety and structure first, then functional systems, and finally cosmetic improvements.

When we find hidden damage, we explain the issue, provide a written change order, and get your approval before proceeding.

Plan a contingency. Typical guidance is 10 to 15 percent of the estimate. For full restoration boats, budget up to 20 to 30 percent for surprises.

Remove or Secure These Items Before Drop‑Off

Want the cleanest, longest‑lasting AWL‑GRIP finish? Little prep on your part makes a big difference.

Plan to remove anything you can. Masking around fixed items never looks as good as painting to a bare edge.

Removable gear and personal items

• Take out portable electronics, chartplotters, and speakers so we can prep and paint behind their mounting plates.
• Remove antennas and radomes when possible so we can finish those bases cleanly rather than mask them off.
• Strip canvases, bimini tops, cushions, carpets, and all loose personal items to prevent overspray damage.
• Where practical, remove trim tabs, cleats, rails, vents, and other hardware for superior edge results.

Mechanical and electrical prep that protects systems

We recommend disconnecting or removing batteries during major paint work to avoid discharge or contamination.

If you cannot remove batteries, at least disconnect the negative terminal and stow battery boxes in a dry place.

Cover bilge pumps and wiring to keep paint chips and dust out. A clogged pump can become a serious safety hazard.

Minimize fuel in tanks when practical and mask fuel fittings and sending units to prevent contamination during sanding and painting.

Do not paint sacrificial anodes. Mask or remove them so they stay electrically exposed to seawater and keep protecting your boat.

If you want us to handle brightwork or remaining items, tell us up front. We offer brightwork and hardware services.

Leaving items on board is possible, but it risks damage and can add time or cost to the job.

Prep steps, primers, and finish choices that protect your new AWL‑GRIP paint

Want a mirror‑like AWL‑GRIP finish that lasts? Small prep steps before drop‑off make the biggest difference.

Start with thorough cleaning and degreasing using a two‑cloth method, as AWL‑GRIP recommends, to remove oils and contaminants before sanding. That simple step prevents adhesion problems and cosmetic defects later. AWL‑GRIP maintaining guidance

Follow a proper sanding progression to avoid visible scratch print‑through. Use coarser grits around 80–120 for heavy removal and fairing, 120–220 for old paint, and 220–400 for final smoothing.

Fairing, fillers, and feathering repairs

Address dents, gouges, and low spots with Awlfair fairing compounds so the topcoat lays on an even surface. These fillers must be sanded between applications to achieve a flawless finish.

Feather small repairs far beyond the damage so edges blend invisibly. Typical feathering moves through 220, 320, 400 and higher grits during final blending.

• Clean and degrease all painted areas with approved solvents before any sanding.
• Mark areas that need fairing or structural repair so we can estimate labor and materials accurately.
• Expect multiple sanding passes and filler applications for heavily worn or pitted surfaces.
• Plan to let repairs cure fully; rushing cures or sanding creates adhesion and finish problems.

How color and special finishes change the job

Color choice affects heat, repairability, and longevity. Dark colors absorb far more solar energy and can reach much higher surface temperatures than white.

That extra heat increases thermal expansion, stresses hardware, and can reveal print‑through on older GRP cores. AWL‑GRIP color guidance

Metallic and pearlescent effects look spectacular, but they are harder to spray evenly and harder to blend during repairs. Products like Awlcraft SE are designed for these effects, yet they still require controlled application and experienced sprayers.

Bottom line: do the prep right, pick colors with the job in mind, and plan repairs into the schedule. We handle the technical primer and fairing work, but your thorough cleaning and clear direction speed the process and protect your warranty.

What to expect for timing, haul-out logistics, environmental rules, and your warranty

Wonder how long a professional AWL‑GRIP repaint will tie up your boat and what you must handle beforehand? Knowing the timeline, transport needs, regulatory limits, and warranty traps helps you plan smarter and avoid surprises.

According to AWL‑GRIP guidance, preparation is most of the job and cure times drive the calendar.

AWL‑GRIP topcoats cure in stages: a first cure around 12 to 24 hours, a second cure at 72 to 96 hours, and full cure in 14 to 21 days. You can often return to limited service after the second cure, but the coating needs weeks to reach full strength.

Haul‑out, blocking, and shop access

Shops need clear access to haul, block, and move your boat through prep, primer, and paint bays. Indoor, ventilated spaces or temporary enclosures are preferred to control overspray and meet environmental rules.

Do your part before drop‑off: remove loose gear, disconnect batteries if possible, and empty or mask fuel fittings. These steps speed work, protect systems, and reduce the chance of added charges or delays.

Environmental rules and waste handling to avoid fines

Painting is regulated for air and water protection. Follow rules and shop BMPs to avoid fines and pollution.

• Watch VOC limits. Some jurisdictions enforce strict marine coating VOC rules and violations can mean fines.
• Control overspray by using indoor booths, tarps, or low‑overspray spray equipment and avoid windy days.
• Treat solvents and leftover paint as hazardous waste. Do not pour them down drains or into the water.
• Never plan major sanding or spraying while the boat is in the water. Marinas typically forbid in‑water painting.

Warranty basics and common ways owners accidentally void coverage

AWL‑GRIP warranties vary by product and application, typically from about 12 to 36 months. As a certified AwlGrip Paint Center, we back our Awl‑Grip work with a longer, five‑year guarantee in many cases.

Warranties require professional application and documentation. Keep invoices and, when available, the application log and batch numbers.

• Avoid unauthorized thinners, additives, or incompatible primers because they void warranty coverage.
• Do not use abrasive pads or harsh polishing compounds that the manufacturer limits for topcoats.
• Prevent trapped moisture. Do not shrink‑wrap wet boats or leave wet gear against fresh paint.
• Register warranty paperwork if required and confirm the warranty commencement date with your applicator.

Bottom line: plan on at least a week before limited use and two to three weeks for full cure. Allow extra time for repairs found during inspection, follow environmental rules, and keep your documentation to protect the warranty.

Get a Smooth, On‑Schedule AWL‑GRIP Repaint

Keep three simple takeaways top of mind so your repaint stays on time, on budget, and warranty‑safe.

• Complete structural repairs first so transoms, stringers, and cores are sound, cured, and faired before painting.
• Remove or securely stow removable gear and disconnect batteries so systems stay protected and we can paint to bare edges.
• Understand prep, timeline, and warranty rules: expect thorough cleaning, sanding and fairing, staged cure windows, environmental limits, and a contingency budget.
