Are you able to sand floorboards painted with sand?

This begs the question: Can you paint floorboards without sanding them?

You can paint a wooden floor with no sanding. However, you should take care not to damage the walls. If you decide to apply a second coat paint on top of the first, then continue as before. This is it! No need to sand!

What should you do before you paint walls or sand floors? If you're getting professional work done, it's better to paint the majority of the walls after the flooring has been installed. It is best to do any wall prep work first, such as ripping up wall papers, patching holes in walls, and so on.

Another question is: Should you sand the floorboards?

You can sand the floorboards diagonally with a large drum sander if they are very uneven. Then, you can move to the boards. You should always sand with your wood grain.

Is vinegar able to remove paint from wood?

Vinegar can be used to soften paint. It won't take the paint off, but it will soften it up so that scraping is much faster and easier. Simply heat some vinegar in a saucepan or microwave, and then use a brush to apply it to the surface. Allow it to cool for a while before testing the paint.
