Thanks buddy. I don't know if I will have DIY story, it's a tedious cut and paste job, need to move stuff around and replace the flooring but that's all. It's probably a few days work, but the content is only 4 lines.
Move the furniture.
Take out the old and disgusting flooring.
Replace the new vinyl flooring
Put the furniture back. Don't drag it, or it spoil the new vinyl and we gotta repeat from step 1 again 🤣
