preparing to install subway tile backsplash
I'm getting ready to install subway tile backsplash in the kitchen but when i removed the old tin tiles, they have tile adhesive or mastic stuck to the wall. What is the best way to remove and or prepare the wall to add the new tiles?
Thanks !!
Thanks !!

Have you tried scraping off the mastic? Often that will tear the drywall paper and if it does, those areas need to be coated with either Zinnser's Gardz or an oil base primer.

I would use a 6 to 8 inch taping knife, like the one below.

Over the years, mine have become very sharp. They will readily and evenly knock off high spots of plaster, glue ect. The wall doesnt have to be completely smooth as the new mastic or thin set will be applied with a notched and will have a slight amount height to it. But it must not have high spots.
As said, if the drywall is torn, you must seal it with a quality NON latex primer.
