I've removed browning from brickwork and breeze block with an SDS drill tile spade some of it just fell away some areas were more tenacious.
There is a thin coating in many areas embedded into the breeze block surface.
Besides removing as much dust as possible, do I need to prepare the surface prior to dot and dab with some sealer such as pva are similar or will the dot and dab adhesive stick okay on its own?
