Can you put cement over a painted wall?
Mortar cannot be installed directly over painted concrete itself. First, a surface more textured and solid must be applied over the painted concrete. This surface is called a scratch coat. A scratch coat will give the mortar something to hold on to, instead of the layer of paint over concrete.
