Will this kill and prevent mold from growing on the backside of unfinished drywall and bare unsealed wood?

It doesn't kill the mold, it keeps it from spreading outwardly by encapsulating the spores. Remember mold sends "roots" out into the material. To prevent/kill mold get rid of the moister source and adequately dry the material its on.

How exactly do you use this product? Do you need to cover furniture or other things? How long does it take to dry? How often should you use?

Follow the directions on the label. The basic way is to spray it directly on top of the surface of the mold. It is not sprayed in the air so furniture and other things don't need to be covered. The dry time, if the humidity is normal (low), should be about 5 minutes, max10 minutes as the mold doesn't need to be saturated, just covered. Once all the mold has been covered/sprayed you won't have to use it again, unless the mold has spread to other areas. If this is the case run a dehumidifier to dry out and remove the moisture from material it's growing on and then you can spray the new mold growth.

It says use for fabric. Is this good for painted dry wall too?

Yes, but remember the mold is most likely started on the backside. See my other reply's for additional information. If you just want to hide the stain/mold use a alcohol or shellac based primer then paint. Use in well ventilated area. See other reply's. If you start smelling a musty smell you'll have to dry out the wall cavities and wood framing by removing the bottom 8" or so of the drywall and use a fan to circulate the air in the wall then you can use this product again. Remember you don't want a "sick" unhealthy house.
