Replacing worn boat carpet or laying fresh carpet on a trailer bunk isn't complicated, but the details matter. Marine carpet is purpose-built boat flooring designed to withstand sun, moisture, and constant foot traffic on decks.
Bunk carpet is a different replacement product built to cushion and protect the hull. This guide covers how to pick the right boat carpet for your vessel, which adhesive to use, and how to install both.
Different boat types cater to different weights and widths, so whether you're refreshing a bass boat deck, doing a boat carpet replacement on fishing boats, or wrapping trailer bunks, the rules are the same: match the material to the boat, use the right adhesive for the backing, and plan for a clean install. Midwest Fabrics stocks marine carpet, adhesives, and boat interior accessories.
Marine Carpet vs. Bunk Carpet: What's the Difference
Deck carpet and bunk carpet often get lumped together, but they serve different jobs. Marine carpet for boat decks is a cut-pile boat flooring made from solution-dyed polypropylene, engineered to withstand UV, water, and traffic. It gets glued down across the deck, hatches, and sidewalls. Bunk carpet is denser, thinner, and rubber-backed. It wraps the wooden bunks on a trailer to protect the hull as the boat slides on and off. Deck boat carpet is measured by face weight in ounces; bunk carpet is measured by thickness and locked down with contact cement and stainless staples. Solvent deck adhesive attacks bunk rubber, so match the product to the job before you purchase.
Choosing the Right Marine Carpet for Your Boat
Marine carpeting comes in weights like 16oz, 20oz, 24oz, and 28oz. Higher face weight means more fiber per square yard, which offers a plusher feel and better durability in high traffic areas. Lighter 16oz styles fit storage compartments and hatches; 24oz and 28oz styles offer the durability main decks need.
Boat types with heavy foot traffic across the whole deck should skip the lighter weights and go 24oz or higher. Solution-dyed polypropylene, also called olefin, is the widely used marine carpet fiber.
Color runs through the entire strand, so the material resists fading, and polypropylene resists mold and mildew, drains water, and offers real value on boats that live outdoors. Marine-grade backing offers drainage holes so trapped water escapes instead of pooling under the boat flooring.
Standard widths are 6 feet and 8 feet 6 inches, and those two widths cover most boat decks in a single run without seams. Roll length runs up to 30 feet, with a 5-foot minimum order. Check the total length and width of the area before ordering. If your deck sits between the two widths, the wider 8-foot 6-inch width offers the most flexible margin and the best value on cutting waste.
Bass Boat Carpet Weights
Bass boat carpet is commonly available in 18oz, 23oz, and 28oz weights, and the right bass boat carpet weight comes down to how the boat is used. The 23oz bass boat carpet is the most popular pick because it balances plush feel with durability.
The 28oz bass boat carpet offers the thickest pile for anglers who spend long days on the water. Most owners on a serious bass boat build choose 23oz or 28oz bass boat carpet for the casting deck; lighter 18oz bass boat carpet fits a bass boat that stays covered between trips.
Match the width and length of the bass boat deck before you purchase, and choose the quality fiber weight that fits how often the bass boat sees water.
Pontoons and Fishing Boats
Pontoons benefit from 20oz to 24oz on the main deck, since the flat, open layout means every square foot gets traffic. A thicker 24oz style holds up longer than 20oz where seating and traffic overlap. Fishing boats with narrower walkways use lighter styles on the sides and thicker material in the casting areas. Snap-in boat carpet offers a removable option in various colors and styles that lifts out for cleaning without pulling up glued sections.
Marine Grade Carpet vs. Outdoor Carpet: What Sets Them Apart
Outdoor carpet and marine carpet share traits like UV and mildew resistance, but marine grade carpet is built to a higher standard. Marine grade construction offers drainage backing plus tighter tuft binding that withstands the flex of a boat hull. Patio outdoor carpet doesn't offer that same structure, so its backing is simpler and less durable. If the flooring will get wet often, marine grade is the best choice.
Best Marine Carpet Glue and Adhesive for Boat Flooring
Adhesive choice makes or breaks a marine carpet install, and the right pick offers years of hold. For decks, use a water-based marine carpet glue like Roberts 6700 or a comparable outdoor-rated adhesive. Water-based products bond well to plywood and aluminum, clean up with water before curing, and stay safe on rubber-backed material. Solvent-based adhesives dissolve rubber backing, which is why they're wrong for marine flooring.
For bunks, contact cement is the standard boat carpet glue. Apply it to both the wood and the back of the carpet, let it flash off, then press the two surfaces together. Stainless staples along the edges lock the material in place through years of trailer use. A marine carpet adhesive rated for outdoor use can offer better protection against sun and moisture than a general-purpose product. The upholstery adhesives collection groups these adhesives by application.
How to Install Marine Grade Carpet on a Boat Deck
Boat carpet replacement follows a repeatable process. Pull the old boat carpet, scrape residue from the deck, and vacuum thoroughly. Dry-fit the new carpet before spreading adhesive: roll it out, trim to rough shape with a couple inches of overhang on each width and length, and mark hatches and hardware openings with chalk.
Fold half the carpet back, spread adhesive on the exposed deck with a notched trowel, and press from the center out. Repeat on the second half and trim final edges. For hatches and curved edges, cut relief slits so the carpet lays flat. Let the adhesive cure overnight.
How to Install Boat Trailer Bunk Carpet
Boat trailer bunk carpet is a shorter install and a breeze compared to a full deck job. Remove the old carpet and staples from the bunk boards. Cut the new material 2 inches longer than each board and wide enough to wrap around the top and sides; check the length and width of each bunk before cutting, and box up any offcuts for later patches.
Apply contact cement to the top of the bunk and the underside of the carpet, and wait 10 to 15 minutes until both surfaces feel tacky. Center the carpet, press from the middle, wrap the sides tight, and secure with stainless staples every 4 to 6 inches along the underside.
Staples stay hidden and out of contact with the hull. Note the install date on the underside of a bunk board with permanent marker so the next replacement cycle is easy to plan.
Marine Carpet Care and Maintenance
Marine carpets inhibit mold and mildew, but they still need routine cleaning. Rinse the deck after each trip to remove salt, fish slime, and debris. A soft-bristle brush and a mild boat carpet cleaner handle most staining. Avoid bleach and harsh solvents that break down the fiber binding.
Textured marine-grade surfaces provide traction on wet decks, and keeping the boat carpet clean preserves that grip. Check edges once a season for a sign of lifting and re-glue any spots that have separated. An adhesive rated for outdoor use also offers a longer service window between reglue jobs.
Owners who hear a squelch when they step on a section of deck should refer back to those edges first, since trapped moisture is usually the culprit. A quality install treated this way can offer a durable service life, often a decade or more before replacement.
