How do you fix the floor on a pop-up camper?

In today’s article, we will answer the following question: How do you fix the floor on a pop-up camper? We will explain how you can easily fix or replace a damaged or rotten floor on a pop-up camper. 

How do you fix the floor on a pop-up camper?

It is easy to fix the floor on a pop-up camper once you locate the damage. If you notice that the floor parts in your pop-up camper have become mushy or unstable, it could be an indication that the floorboards, or worse, the supporting floor joists, are rotting and need to be replaced

Like most structural repairs, completing them when you first notice the problem will likely cost you less than if you let the problem go and let it get worse. Complete the repair as soon as possible after discovering that the pop-up camper floor is weakened.

Here’s how you fix the floor on a pop-up camper:

  1. Remove as much furniture and accessories as possible from inside the pop-up camper. This may require unscrewing cabinets or drawers from the walls and carrying them out. You want as much exposed floor space as possible.
  1. Remove the carpet from the inside of the pop-up camper. Start at a wall or corner and begin peeling off the carpet. If the wood subfloor is rotten, the adhesive that holds the carpet or vinyl flooring will often weaken, making it easier to remove.
  1. Remove the affected area from the floorboards with a crowbar or cut it out using a jigsaw. Inspect the joists under the subfloor. If they are solid, then they do not need to be repaired. If they feel soft or are black from moisture contamination, run two lengths of the same size lumber on either side of the affected joist. 

Drill a hole through the three pieces of wood in a solid part of the floor joist. Insert a bolt through the holes and put a nut on the other side to hold the wood in place. Repeat this on the other end of the support lumber you are installing. It will firm up the floor beam and will give you a solid structure to screw the floorboards into.

  1. Cut a piece of plywood that is the same thickness as the wood that has been removed, positioning it in the match when removing the rotten floorboards. Use wood screws to secure the new floorboard in place.
  1. Replace the carpeted or vinyl flooring with new carpet or vinyl and reinstall drawers or cabinets that have been removed. Replace the furniture, and your pop-up camper is ready to be used again.

Here’s how you replace rotten pop-up camper floor

Like everything, the pop-up camper floor needs maintenance. One common issue with older or badly kept campers is the wooden floor in the RV, which can rot. Replacing is a good project and it will take time and effort.

  1. Remove the rotten floor on the pop-up camper with the iron bar and a hammer. You are going to have to lift each individual nail by pushing the lever on the end of the nail and pulling it back. Remove all the flooring from the pop-up camper until one is left with the metal subfloor.
  1. Remove the insulation on the floor with your hands. Depending on the type of insulation, you may want to wear gloves so that your hands are not injured.
  1. Place the new insulation between the floor studs, filling in as many gaps as possible.
  1. Install the lumber by which each blade was obtained onto the studs and hammer it into place with the hammer and nails. Make sure none of the seams is on the plywood line and that they are staggered like a brick pattern.
  1. Measure for cards that are not standard size and cut the plywood to size using the circular saw and sawhorses. Mark the panel using the pencil, then place the wood on the easel to cut.
  1. Nail the remaining boards to the plant using the hammer and nails.
  1. Apply laminate flooring, remove the backing from each tile and glue it to the plywood. Make sure each tile is lined up edge to edge with the one next to it.

How can water damage your pop-up camper floor?

On prolonged contact with water, the wood fibres in the pop-up camper floor swell, which can damage the surface of your floor. If you use too much water to clean your camper floor, the strips may be damaged. And your floor will lose its elegance and authentic properties. Maintaining a varnished floor is essential to its preservation.

In all circumstances, it is recommended that you place a mat in front of your dishwasher and kitchen sink to protect the floor from damage from water, soap and all other liquids. Choose rugs that have a non-abrasive surface underneath. This will make them safe for your soil.

Immediately wipe up any water, liquid or detergent spills on your floor surface before it seeps under the planks of your wooden floor.

Use rimmed rugs at each entrance door to catch water, salt, and snow. Beware of the calcium from the salt that cities use to melt snow during the winter season. It can be very damaging to your floor, because it directly attacks your varnish, drying it out and removing its protective properties.

Place plates of your waterproof plants under the pots to prevent accidental water spills that could harm your camper flooring. Indeed, prolonged exposure of your wooden floor with the pot of an unprotected plant could cause an entrenched ring. The only way to fix this situation will be to perform a floor repair.

The consequences of water damage can be disastrous: rotten floors, damaged beams, and so on.

To effectively and durably treat a damp pop-up camper, it is essential to call in a professional. Only a specialist can:
