I posted similar to this elsewhere as i overlooked this section. I have opened up a fireplace in which i want to tile over the bricks. I have removed plaster from the wall too where i want to tile, to keep it flush with coming out of the fireplace opening. The bricks what were under the plaster are very dusty (from the old plaster) (and some soot staines within the fireplace). I am no expert at tiling and wish to purchase products ready mixed etc. How and what would you do to prep the surface and what tile adhesive given the high temperatures they will be exposed to once the stove is fitted?
