Just bought our first home a year ago. I want to remodel the main bathroom because it is in desperate need. My question is does anyone know what this on the walls? It looks like linoleum. If anyone knows what it is and by chance how it is installed. What I mean by that is, like does this normally get put on over drywall? What do you think is underneath it? All the other walls in the house are plaster. I was considering just painting over it for know a taupe or creamy color. Idk. Thanks in advance for your responses.
