mudding/floating painted walls
We will close on a house next week. The first thing my wife wants done is to re-texture then repaint. The current texture is very "aggressive" where there are obvious dips and bowls. Those are the only terms I can describe them. The texture was sprayed on and knocked down, but done unevenly. There are also two walls where they owners went a step (actually 3 or 4 steps) further and sponged on several layers of paint. Anyways, I plan to mud all the walls, but I'm not sure on what to use as a cleaner. I don't want to use TSP as I'm not sure I can thoroughly rinse it out of all the features of the textured walls.
I've done a search here and have read about powdered dirtex. Would that work better? In the event that I can't find it locally, can I use something else? maybe wipe on a mixture of vinegar and water? ammonia and water?
