Flooring – Repairing 2 long cuts in vinyl flooring

In answer to Mike's question about a repair kit, my first thought is to go to a local store that sells no-wax flooring. They would sell you a repair kit. Second thought is to look on Amazon, there I found a Vinyl flooring repair kit: that includes what you need for a color match. Apparently it cures when you apply heat, so I'd use my heat gun, but a hair dryer might work too. (I see that one online reviewer said it did not harden for them, but it sounds like they did not read the instructions about it needing heat to cure.)

The repair kit I had used for spot repair in the past was basically a tube of clear cement. You dabbed it on and it air cured. It was really designed to seal the seams between two pieces of flooring, but that was where I needed it.

If you are unsure about how to do something like this, a great idea is always to find a scrap to practice on. That local flooring store would surely have a scrap piece of flooring to play with, if you don't have one.

I think I would jack the wall up a tiny bit (1/16 inch), enough to slide out the particle board and slide in plywood.

Given the difficulties of jacks being in the way of the work, cut the plywood so it is only 12-16 inches wide (and 8 feet long or whatever) so the jacking support can be away from the wall.
