Interior Wall hardener?

I had a contractor come by and as he looked at different parts of my house he noticed my weak cellotex interior walls and mentioned there was something he could apply to these walls called (twenty) or something like that which once applied would make the walls extremely hard. I was wondering what the product might be. Sure sounds more fun than transporting, cutting, hanging, and securing drywall to me.

Any ideas?

I did a quick search on Wall Hardener.

I don't think its meant to make walls stronger or better but only to make the surface harder.

Lets see what our paint experts say.

There are binding agents like the one that Norm supplied a link for that will make textures less water soluble but they are generally added to the texture. I doubt they would work over an already painted wall.

Oil base paints dry to a harder film than latex, waterborne paints have a film that is almost as hard as oil. I'd want more info on the coating he proposed!
