Painting - Can't get rid of the sanding dust HELP!!

I've wiped the walls down with a damp sponge 3 times and I still can see dust on my hand. Is the damp sponge raising the joint compound????
I never did get an answer as to the "right primer" for this job.

Try a tack cloth instead.

As for primer, get a good quality paint like Sherwin Williams or Benjamin Moore and then use whatever primer is recommended on the paint can.

I usually sweep the walls with a push broom [minus the handle] and prime. A damp sponge/rag will do a better job of removing the dust but it can also soften up the joint compound. As long as the majority of the dust is removed you should be fine.

A latex wall primer should be fine but a lot depends on what the finish coat is to be. Many different primers are formulated for new drywall but most have a specific type of top coat in mind. Ask at the paint store which type of latex primer would be best for the type of top coat you will be using. Having the primer tinted may save a coat of the finish paint.

I use a dry-type swiffer
Works great
IMO the damp sponge doesn't quite cut it

A damp sponge will take off joint compound. Indeed, if you look at a tub of joint compound, it is how the instructions suggest you smooth the final coat.

Go with a tack cloth, as others have said.

Thanks!
I like the swiffer idea, pretty sure the wife has one of those.:D As for my push broom, well the only one I have is my garage broom and I sure ain't wiping down walls with that.:o The last time I used it was to spread kitty litter over an oil spill. Never leave an oil spray can where little hands can play with it.:rolleyes:
I sometimes use a tack cloth in my wood shop, it leaves a stickey residue. Would that happen on a wall?????:confused:
