Simple Steps on How to Replace Boat Floor

Here are the steps on how to replace boat floor:

Step #1. Clear the area of the floor you want replaced. 

  • Check for fixed seats, decors, wiring, and other elements that could interfere in the removal of the floor tiles. 
  • Remove or detach these attachments to clear the floor area.
  • Make sure that the floor area in the deck is dry. 

Step #2. Remove the existing flooring. 

  • Begin removing the old flooring. 
  • Leave at least a 3-4-inch allowance on the frame aligning the edge of the boat. This should make it easy and safe to replace boat floor.
  • When removing a soft and spongy boat floor, avoid holding it in the middle as it can cause the floor tile to crack. Instead, hold it from the tip of the tile. 

Step #3. Reconstruct the new floor. 

  • To replace boat floor, prepare the all-new plywood for measuring. 
  • Using the old floor tiles as a model, measure and cut the plywoods (if needed) to fit into the existing frame. 
  • Fix holes for screwing into the wood floor tiles. 
  • Once done, coat the wood tiles with epoxy to water-proof them. 
  • With the frame and screws all set, attach/lay the flooring. Add new holes if necessary. 

Step #4. Seal the floor area.

  • Once reconstructed, finish the floor with the fiberglass strand. 
  • Pour in resin after and then spread. 
  • Once the sealed new floor has dried, sand it to polish. 
  • Create new holes aligning the seal (resin) and the floor tile. 
  • Screw the sealed floor tiles into the deck. 

Step #5. Layer in a carpet or any external pads. 

  • With the new floor screwed, lay in any carpet or external padding for added protection. 
  • For the final part of your boat floor replacement: re-fix the seats, tools, and other materials into place. 

Congratulations — you’ve reached this far. You can replace the boat floor anytime and expect success.
