I live in a shabby share house. It has one main toilet with some mix n match tiling. I am thinking of painting the tiles to look like a pixel mosaic, perhaps of Van Gogh.
Some googling suggests I could use oil paints. I would apply with a brush to each tile. This is fine but would cost like £40-60 in paint. Is there a cheaper option?
Should I do a spray coat of white primer first? Would likely require two cans.
Also can I please borrow an orbital sander from anyone for the prep work (if that is indeed the best idea)? Can offer beer. The tiling is slightly uneven in depth across the wall, i.e. it's not a flat surface, so is this even the best sanding approach?
