I am in process of painting the house and want a smooth surfaced walls.
How do I remove the texture from the walls?
I purchased a sanding attachment for my shop-vac that has a hose, two different size connectors, a sanding pad with holes for airflow and 1 piece of sanding screen. I used it to sand patching and paint build-up this past weekend and I found it worked quite well. I had very little clean up and found the suction was adequate after I had put in two new filters (the one around the blower is the most important). One thing I did find, though, is that you would likely need medium and a fine screen to get a good finish suitable for painting.
When all is said and done, though, it might be a lot quicker and easier to get a drywaller or plasterer in to put a skim coat on to flaten the walls. That's probably your best bet for a good finish.
