My living room wood floors are too thin to sand

I would go with Porch and Floor paint.

Many hardware/paint stores sell paint made just for floors. I'd check out each option, or do a light sand, and stain.

Great choice! And a wonderful way to save them. Here are some really good tips!

Floor paint

pirch and floor is what will hold up best!

porch And floor paint, sorry for the spelling errors

Depending on the look you're going for- you could start with white Kilz & that will cover a multitude of sins. then you can do anything you want style or color wise- stencils, patterns, a new texture. I covered 2 floor types in 1 redo. You can see it in my projects. It was suprisingly easy!

thank you all for so much good information. i really appreciate it

It is very likely you have completed this project. Just in case, refinishing a floor is an alternative to sanding. It is similar to a piece of furniture, only larger. Won’t remove major defects (deep scratches and stains) but will greatly improve any floor’s appearance.
