Don't do it in sections unless you have to. The less seams you have the better.
This way will work fine, but you have to make sure you're going perfectly straight! 1/4 of an inch at one end could mean you are out by 4 inches at the other end and it will look silly.
Some tips before you start
- Make sure the floor is clean. No dust or small rocks
- Don't do this on a windy day
- Take your time
- Glue can stink, it can also cause issues in an enclosed space. Open up windows and doors for ventilation
- You can also check Youtube for how to videos
1) Roll it out
3) Measure again
4) Mark the roll for cutting
5) Measure it again
6) Preliminary cut, leave an inch or so extra as a rough cut
7) Double check it all fits and trim the excess
Practice a dry run by rolling it out with no glue first
9) Roll it up so that you can start at either the front or the back. You want to finish where it will be easier to get out of the vehicle
10) Begin by putting some glue on the floor and place the roll on it.
11) Then begin slowly backing up and either putting glue on the floor or on the roll itself (floor is easier) and slowly back up
Your alternative is to find someone with experience laying down linoleum flooring or take it to an RV shop and pay for them to do it but these ways can get expensive.
