How to replace your trailer Bunk Board Carpet

1)  Unbolt and remove existing bunk boards from trailer. Take the existing bunk carpet off and sand away any glue or debris before applying new carpet. Also examine the old bunk boards and make sure that they are not warped or broken. Replace if needed. Obviously skip this one if your starting with new bunk boards.

2) Measure the size of your boat bunks to determine how many rolls of bunk carpet you will need. (See "Note" at bottom for suggested measuring method)

3) You may either glue or staple your replacement bunk carpeting down. We would suggest just to staple your new bunk carpeting. This will allow the carpet to give a little while loading and un-loading your boat and prevent tearing of the carpet over time.

4) Before carpeting your trailer bunks take the bolts used to secure your bunks to your trailer and insert them into your already drilled out holes on your bunk board. Follow the steps below with the bolts inserted through the drilled out holes on the board. This will allow the carpet to be applied over the head of the bolt preventing it from scratching the bottom of your boat or pontoons.

5) Unroll and layout your new carpet (which you have already cut to size) with the rubber backing facing up. Place the bunk board evenly right to the edge of the laid out carpet. Leaving enough carpet on either end to completely wrap each end of your bunk. Hold the carpet to the board and start to roll the new carpet onto the bunk board. Staple down the first side. Then roll the board until it is completely covered. When you get to this point take a staple gun and apply staples every 2 to 3 inches along the bottom of the bunk board. This will ensure a secure and snug fit. If measured correctly when cut there should be about 2 inches or so of carpet left to overlap the first initial bottom side, staple down this excess carpet on top of the existing carpet. 

(If you plan to use marine carpet glue please be sure to use water based carpet glue, other alcohol based adhesives will eat away the rubber backing of the carpet.)

6) Take the newly wrapped bunk board and place it with the bottom side up one last time and use the excess carpet you have already accounted for at either end and wrap, securing with glue or staples. Overlap and secure the excess carpet to the bottom side of the bunk.

7) Place your new bunk board off to the side and repeat steps for remaining bunks.


For a better look, plan to wrap the entire bunk board, ends too. The majority of trailer bunks are made using standard 2x4 or 2x6 boards.

The actual measurements of a (in inches):


bunk board measurements

For bunk carpet installation: The width of the replacement carpet for each bunk should be at least 12 inches wide for 2x4 bunks (16 inches wide for 2x6 bunks). This allows an extra 2 inches of carpet to overlap on the bottom of the bunk which lets you easily secure the carpet around the bunk. When measuring the length of each bunk board add an extra 7 inches to the total length, to be safe. This allows for an extra 3.5 inches of carpet for both ends of the bunk. 1.5 inches of that is used to cover the exposed wood at either end. The other 2 inches is overlap so that you my secure the carpet easily at both ends with a staple gun and/or glue.

**Special Note**

For those who have bunk boards that use 2x6 size boards. Our 16oz. rolls of marine carpet can be used because the 12in wide rolls of bunk carpet are not wide enough to fully cover the 2x6 application. For a 2x6 application you will need your replacement carpet to be about 16in wide per bunk to be safe. These rolls of our 16oz marine grade carpet can be taken and cut into 16in wide strips.

There are 6ft wide and 8.5ft wide rolls available.

  •  A 6ft (72in) wide roll will allow you to cut 4 16in wide strips.
  •  A 8.5ft (102in) wide roll will allow you to cut 6 16in wide strips.

***As an added bonus there are 15 different colors of our 16oz carpet available and in stock to choose from. In some cases purchasing a full roll of 16oz or 20oz carpet and cutting it into strips for your bunks may be cheaper than purchasing multiple pre-cut rolls of bunk carpet. There is no difference in quality between our pre-cut bunk carpet rolls and our full rolls of marine carpet. All of our carpet is tough, durable, fade resistant, rubber backed and made specifically for use in the harsh marine environment. Click HERE to be taken to our 16oz marine carpet color choices.
