Hi, so I’m relatively new to tiling. I’ve got a job where the walls aren’t 100% flat but not the worst. I’ve sealed the old plaster with a primer. Am I ok to dot and dab the tiles, I don’t mean 5 dots with 20% coverage, the dots I’d put on would get a minimum coverage of around a 70% adhesive bed. Is this ok? The tiles are 600x300. Thanks
