Why is it that you feel you need to wash or sand the walls, smoke and or nicotine damage? I can't remember the last time we washed walls. Are the walls latex or oil? If they have satin or semi gloss latex on them now I would just slap another coat of the same product on them and be done with it.


In some cases like old thick glossy apartment painting we use 80 grit sandpaper to bite into the surface and provide key., also removes allot of surface impercections

The thing is with painting every job is different so you may not need to perform the same taks on every job. Me personally I would not sand latex semi gloss textured walls just to repaint them. The paint will stick. With that being said if there is oil paint, smoke, or wax of any kind on the surface or any other film or gresse yes sand and or wash the walls before painting. You may even want to consider an oil base oderless primer if need for interior projects

You are right. But, you asked about an alternative to sanding or washing.

Priming is the only thing I can think of, but that's not what you're after.
What we're saying is that a quick pole sand will scuff the surface, break the gloss enough to get better adhesion. If it were trim, or a table or something that needs more protection, then more sanding is needed.

But anyway, I don't know of any tricks other than sanding or washing. There might be a no rinse, spray on product out there.
